<b>The User Experience of Viewing Captioned Content</b>
 +
<br>
 +
Much has been made of the ability of automatic speech recognition (ASR) to supplement or replace human captioners both for video content and for live meetings. While the word error rate of ASR has been steadily improving, and on some types of content can even beat out human captioners, these improvements do not automatically in a good user experience for people who are deaf or hard of hearing. In this talk we will examine the reasons why this is so, and provide an overview of current efforts to develop human-centered caption quality metrics that are more closely aligned with meeting the needs of people who depend on captions to consume content.

<b>Promoting Pro-social Behavior with End-to-End Data Science</b>
 +
<br>
 +
The recent development of data science methods, including large-scale machine learning and causal inference, has presented a game-changing opportunity for social good provision through the effort of the crowd. In this talk, I introduce an end-to-end data science pipeline to promote behavioral change for pro-social benefits. More specifically, this involves conducting causal data analysis on empirical data for actionable insights and robust prediction models, incorporating the insights and predictions in designing recommender systems for individual actions, and evaluating the effectiveness of the recommender systems in promoting behavioral changes with randomized field experiments. I will present two applications of the end-to-end pipeline, where we designed and deployed team recommender systems on an online microfinance platform (Kiva.org) and a ride-sharing platform (DiDi). We evaluated the recommender systems through large-scale field experiments, which show significant increases in user participation. The recommender system has been deployed in DiDi and has impacted millions of users in practice.

<b>Quantifying Human Performance and the Quality of Immersive Experiences</b>
 +
<br>
 +
Psychometric evaluations are generally used to understand the Quality of Experience (QoE) of immersive environments produced using augmented/mixed/virtual reality. Typically, these subjective evaluations are done from an end-user point-of-view, but these are limited by the subjective observations due to a number of factors. The objective approach consists of measuring the QoE by monitoring the network technical parameters or the network Quality of Service (QoS), such as throughput, delay, and packet loss. Most of the research on objective approaches for QoS-QoE mapping have focused on video streaming. Such objective QoS-QoE mapping strategies cannot be directly applied for immersive environments.
 +
Hence, in this talk, we address two related questions: (1) Can we identify metrics that can objectively quantify the performance of an immersive environment? (2) Can we use the above objective performance metrics to understand the possible user QoE without the need for subjective user study or with minimal user study? We start with different examples of immersive environments such as haptic-enabled applications, mirror therapy, and games. We discuss what metrics are influenced by different system parameters such as processing power, and network QoS. Then, we present some of our preliminary work on understanding users’ QoE through these metrics.

<b>Celestial: Color Patterns for improving Color Perception for blind people.</b>
 +
<br>
 +
It is relatively difficult to recreate the abstract three-dimensional shape with only the tactile sense. Gibson said "These abilities can be improved through practice." "When you touch something, You may have no idea about it at first touch, but as you continue touching, you soon will know vaguely what it is" , Kojiro Hirose said. 
 +
 +
Recently, we developed "Blind-touch" to aid the visually impaired to appreciate greater painter’s work of art. This work is a reproduction of an existing masterpiece by means of a 3D printer and haptic electronics. It recognizes the pattern by touching the object in the artwork with a fingertip, and voice explanation and sound effect are provided through the voice user interface.  Color is an equaling lens through which we experience the natural and digital realities. Now, we are exploring the tactile-color association based on semiotics  to represent colors  with fingertip tactile sensation. In this way, audio  and touch contribute information to the non-visual perception of color in an complementary manner. In this talk, we review the related works and  introduce a so-called “Celestial color tactile pattern”  built based on the concept of both pictogram and ideogram and its variants.

<b> Human-Centered Artificial Intelligence: Designing Next Generation User Experiences</b>
 +
<br>
 +
The next generation of user experiences will produce 1000-fold improvements in human capabilities. These new tools will amplify, augment, enhance, and empower people, just as the Web, email, search, navigation, digital photography, and many other applications have already done. These new human-centered tools will produce comprehensible, predictable, and controllable applications that promote self-efficacy and social participation at scale. The goal is to ensure human control, while increasing the level of automation. In short, the next generation of tools will make more people, more creative, more often.
 +
<br>
 +
Improved designs will give billions of users comprehensible interfaces that hide the underlying complexity of advanced algorithms. Users will see familiar visual strategies based on direct manipulation to provide informative feedback about the machine’s state and what they can do. Every use will build confidence that users can reliably accomplish their goals and increase the trust that the machine is under their control.

<b>MakeCode and CODAL: intuitive and efficient embedded systems programming for education</b>
 +
<br>
 +
Across the globe, it is now commonplace for educators to engage in the making (design and development) of embedded systems in the classroom to motivate and excite their students. This new domain brings its own set of unique requirements. Historically, embedded systems development requires knowledge of low-level programming languages, local installation of compilation toolchains, device drivers, and applications. For students and educators, these requirements can introduce insurmountable barriers.<br>
 +
We present the motivation, requirements, implementation, and evaluation of a new programming platform that enables novice users to create software for embedded systems. The platform has two major components: <br>1) Microsoft MakeCode (www.makecode.com), a web app that encapsulates an entire beginner IDE for microcontrollers; and <br>2) CODAL, an efficient component-oriented C++ runtime for microcontrollers.<br> We show how MakeCode and CODAL provide an accessible, cross-platform, installation-free programming experience for the BBC micro:bit and other embedded devices.

<b> Towards Automated Fact Discovery and Ranking</b>
 +
<br>
 +
In this talk, I present the work of finding new, prominent situational facts, which are emerging statements about objects that stand out within certain contexts. Many such facts
 +
are newsworthy—e.g., an athlete’s outstanding performance in a game, or a viral video’s impressive popularity. Effective and efficient identification of these facts assists journalists in reporting,
 +
one of the main goals of computational journalism. A situational fact can be modeled as a “contextual” tuple that stands out against historical tuples in a context, specified by a conjunctive constraint involving dimension attributes when a set of measure attributes are compared. New tuples are constantly added to the table, reflecting events happening in the real world. Our goal is to discover constraint-measure pairs that qualify a new tuple as a contextual significant tuple, and discover them quickly before the event becomes yesterday’s news.

<b> Diversity in Matching Markets</b>
 +
<br>
 +
In bipartite matching problems, vertices on one side of a bipartite graph are paired with those on the other. In its offline variant, both sides of the graph are known a priori; in its online variant, one side of the graph is available offline, while vertices on the other arrive online and are irrevocably and immediately matched (or ignored) by an algorithm. Examples of such problems include matching workers to firms, advertisers to keywords, organs to patients, and riders to rideshare drivers. Much of the literature focuses on maximizing the total relevance---modeled via total weight---of the matching. However, in many real-world problems, it is also important to consider the contribution of diversity: hiring a diverse pool of candidates, displaying a relevant but diverse set of ads, and so on.
 +
 +
In this talk, we model the promotion of diversity in matching markets via maximization of a submodular function over the set of matched edges. We present new results in a generalization of traditional offline matching, b-matching, where vertices have both lower and upper bounds on the number of adjacent matched edges. We also present new theoretical results in online submodular bipartite matching. Finally, we conclude with ongoing work that approaches the problem of hiring a diverse cohort of workers through the lens of combinatorial pure exploration (CPE) in the multiarmed bandit setting, and discuss an ongoing experiment in this space at a large research university.
 +
 +
This talk will cover joint work with Saba Ahmadi, Faez Ahmed, Samsara Counts, Jeff Foster, Mark Fuge, Samir Khuller, Zhi Lang, Nicholas Mattei, Karthik A. Sankararaman, Candice Schumann, Aravind Srinivasan, and Pan Xu.

<b> What is Valuing vs “Jerk” Behavior? How behavior impacts a positive working experience</b>
 +
<br>
 +
Women in tech leave the field at twice the quit rate as men. Women often state, and research confirms, that women don’t feel valued. They point to the culture of the organization and how they are treated as a contributing factor. They say that men are “bro’s” or “jerks.” In 2018, we launched the Valuing &amp; Jerk Project as one WITops initiative (https://www.witops.org). This talk
 +
will present our findings and perspective.
 +
Behavior creates or undermines connection and value. The Valuing and Jerk Project focuses on understanding which behaviors are experienced as valuing in everyday work and which result in
 +
naming the other as a “jerk”. Using Contextual Inquiry, we have uncovered core valuing behaviors, what devaluing means, and where behavior crosses the line to become “jerk” behavior. Armed with this understanding our next step is to generate and test interventions and solutions. The talk will introduce the Valuing and Jerk Project.

<b>Underestimating the challenge of cognitive disabilities (and digital literacy). Directions to explore in short, medium and long term.
 +
</b>
 +
<br>
 +
Recent work has caused us to question our understanding of the challenge of digital access by people with cognitive disabilities.  Our underestimation may, in part, help explain our difficulties as a field to date. In part, it has exposed what may be a much wider problem than we understood, and one that goes beyond those we have thought of as having cognitive disabilities. It intersects with digital literacy but also has implications for those with other disabilities as well. The concept of Technology Quotient (TQ) will be discussed and approaches for addressing access by people with cognitive disabilities and low digital literacy today, tomorrow and in the future will be explored in this talk.

<b> Human Factors in Mobile Authentication</b>
 +
<br>
 +
Mobile authentication is a crucial component of authentication more broadly,
 +
especially as mobile devices become evermore connected to the broader computer
 +
security ecosystem. The overarching goal of my research is to improve the
 +
current state of mobile authentication by taking a holistic approach to
 +
measuring mobile authentication and its impacts that intersect directly with the
 +
user experience. In this talk, I will present a narrative of contributions to
 +
mobile authentication over the last 10 years, focusing on how human factors
 +
impact the security, from attacks, choices, and perceptions. I will particularly
 +
focus on one form of mobile authentication, Android's graphical pattern unlock,
 +
which may be the most heavily used graphical authentication system, ever. Based
 +
on my experience, I will also present some new directions and methods that can
 +
improve the security of mobile authentication and some new results on PINs and
 +
LG's graphical Knock Code Authentication.

<b> Storytelling makes research data come to life </b>
 +
<br>
 +
We all love our user research data…but why is it such a struggle to use the insights we uncover to create direction for a project?  Storytelling is the missing link, getting past charts and graphs to dig into what the data means for meeting human needs and making something usable and useful. Whitney will show how stories put research insights into context, communicate the entire user journey, show problems through the eyes of your users, and help you ask better questions (and run better usability tests) to gain deeper insights. Whitney is the co-founder of the Center for Civic Design, approaching democracy as a design problem, so there will be examples from the challenges of designing elections as well as stories from her work in theatre.

<b>Design Democratization in the Age of Machine Learning.</b>
 +
<br>
 +
Design democratization can transform the way we think about designing products. However, to enable design democratization, we need machine learning and computing methods to enable organizations to process a large amount of information efficiently. Using the example of online design contests, we will discuss three problems which organizations face in conducting design contests: a) How does one form teams to evaluate design ideas? b) How does one filter high quality and diverse ideas out of hundreds of submissions? and c) How does one reliably measure the creativity of ideas? We will discuss how matching, ranking, and novelty estimation methods developed in our work address these issues and what challenges remain for the field.

<b>Interactive Fabrication and Fabrication for Interaction.</b>
 +
<br>
 +
3D printing technology has been widely applied to produce well-designed objects. There is a hope to make both the modeling process and printing outputs more interactive, so that designers can get in-situ tangible feedback to fabricate objects with rich functionalities. To date, however, knowledge accumulated to realize this hope remains limited. In this talk, I will present two lines of research. The first line of work aims at facilitating an interactive process of fabrication. I demonstrate novel interactive fabrication systems that allow the designer to create 3D models in AR with a robotic arm to print the model in real time and on-site. The second line of work concerns the fabrication of 3D printed objects that are interactive. I report new techniques for 3D printing with novel materials such as fabric sheet, and how to print one-off functional objects such as sensor and motor. I will conclude the talk by outlining future research directions built upon my current work.

<b>Everyone a Data Scientist: Empowering Casual Users to Understand Complex Data.</b>
 +
<br>

Understanding data is quickly becoming the new digital divide. Merely having access to information and communication technologies (ICTs) is no longer sufficient when our society is overflowing with massive volumes of raw, complex, and heterogeneous data. Since best-practice data science workflows are still only available through esoteric software libraries, typically accessed using the Python and R languages, leveraging this data to its full potential often requires significant programming expertise. Even commercial point-and-click analytics tools such as Tableau, Spotfire, and QlikView require training and assume significant prior knowledge of mathematical, statistical, and sometimes even machine learning concepts. This means that currently only people who have the appropriate data and technology literacy can harness the ready availability of data in our society.
 +
 +
In this work-in-progress talk, I will discuss our efforts for shrinking or outright eliminating this new digital data divide through interactive visualization, explainable machine learning, and collaborative technologies. More specifically, I will talk about several past, current, or planned projects on this topic, including (1) the use of mixed-initiative interaction, which combines both human and computational efforts in the analytical process; (2) the use of attention for computational steering; (3) recommender systems for automatically suggesting the next analytical step in a workflow; (4) direct manipulation methods for interacting with machine learning models; and (5) "team-first" collaborative mechanisms that reduce the barrier to synchronizing and sharing work to facilitate emergent collaboration. This is ongoing research, so your feedback on these efforts is welcome.

<b>Join, Stay or Go? Members’ Life Cycles in Online Health Communities</b>
 +
<br>
 +
This talk discusses temporal changes in members’ participation in online health community (OHC), focusing on their motivations for joining and changes in their motivations as they transition to other roles or ultimately leave the community. We use mixed methods, combining behavioral log analysis, automated content analysis, surveys and interviews. We found that members started participating in OHCs for a common set of reasons, mainly to acquire support and to perform social comparisons. When their need for support decreased, most members quit the site. The motivations of those who stayed shifted to providing support and helping other members in the community. Oldtimers also established social ties with others members, which motivated them to stay in the community. These oldtimers, who contributed the majority of content, encountered challenges that threatened their commitment to the community, including negative emotion related to other members’ deaths. These challenges led them to take leaves of absence from the community or to drop out permanently. Our findings shed light on the changing motivations of OHC members, which provide implications for better designing OHCs.

<b>ORC Layout: Adaptive GUI Layout with OR-Constraints</b>
 +
<p>We propose a novel approach for constraint-based graphical user interface (GUI) layout based on OR-constraints (ORC) in standard soft/hard linear constraint systems. ORC layout unifies grid layout and flow layout, supporting both their features as well as cases where grid and flow layouts individually fail. We describe ORC design patterns that enable designers to safely create flexible layouts that work across different screen sizes and orientations. We also present the ORC Editor, a GUI editor that enables designers to apply ORC in a safe and effective manner, mixing grid, flow and new ORC layout features as appropriate. We demonstrate that our prototype can adapt layouts to screens with different aspect ratios with only a single layout specification, easing the burden of GUI maintenance. Finally, we show that ORC specifications can be modified interactively and solved efficiently at runtime.</p>

Cross-Device Frameworks for Collaborative Visualization
+
<b>It's all about creating new possibilities for people: A journey from the lab to a startup</b>
 +
 
 +
One of the most valuable parts of the DNA of HCIL is its focus on "human", and how our mentors guide us to connect our work with people (users). As a student of this school of thought, I had found my purpose to help the 95% by identifying, questioning, and removing barriers (creating opportunities) in visual analytics. Two years ago, with results baked in lab, and the same driving purpose, I stepped into a world unknown to me: creating, running, and growing a business, one customer at a time.
 +
 
 +
I am back to share some of the surprises, new perspectives, and validations from this journey so far. What I missed can help you realize the opportunities you already have. What I wish I knew may reveal some gaps. And, what remained constant may hint that research in university and what comes after may not be so different after all. I also will touch on the subtle and dynamic balance between your elevator pitch, your audience, the value you provide, and crossing the finish line.

<div class="mw-collapsible-content">
<br> Abstract: Collaborative Visualization focuses on shared use of interactive visual representations of data by a group engaged in joint information processing. However, to fully exploit this, we need to also bring cross-device interaction into picture considering that we carry more than a single device these days. In our research, we created two frameworks— Munin and PolyChrome— for building collaborative visualizations on multiple input and output surfaces, such as tabletop displays, wall-mounted displays, and mobile devices. These frameworks follows a layered architecture to abstract out the communication, interaction, and visualization requirements for the aforementioned. Furthermore, PolyChrome utilizes the web as a medium for collaborative visualization while maintaing a server for persistent storage of visualizations and user interaction over time.

<b>Information Olfactation: Harnessing Scent to Convey Data</b><br>
 +
Olfactory feedback for analytical tasks is a virtually unexplored area in spite of the advantages it offers for information recall, feature identification, and location detection. We have introduced the concept of information olfactation as the fragrant sibling of information visualization, and this talk will cover our theoretical model of how scent can be used to convey data. Building on a review of the human olfactory system and mirroring common visualization practice, we propose olfactory marks, the substrate in which they exist, and their olfactory channels that are available to designers. To exemplify this idea, we present viScent: A six-scent stereo olfactory display capable of conveying olfactory glyphs of varying temperature and direction, as well as a corresponding software system that integrates the display with a traditional visualization display, along with three applications that make use of the viScent system.

<b>Learning in the Holodeck: the Role of Multisensory Cues on Pattern Recognition in VR</b><br>
 +
Designing for multiple senses has the capacity to improve virtual realism, extend our ability to process information, and more easily transfer knowledge between physical and digital environments. HCI researchers are beginning to explore the viability of integrating multisensory media (“multimedia”) into virtual experiences, however research has yet to consider whether mulsemedia truly enhances pattern recognition in virtual reality (VR). In the context of citizen science watershed habitat training, our research asks, how does realism affect observation skills in VR? Within this domain, we build a multisensory system that allows users to feel (wind, thermal, humidity) and smell landscape and environmental conditions. We then compare and report on how users make observations and infer patterns between 2 stream habitats in VR, with and without the multisensory information. Our findings reveal that multisensory information improved the number of high-level, mid-level and low-level observations participants made, and positively impacted engagement and immersion.

A Characterization Study of Exploratory Analysis Behaviors in Tableau <br>
 +
Exploratory visual analysis (EVA) is an interactive process comprising both focused tasks and more open-ended exploration. Visual analysis tools aim to facilitate this process by enabling rapid specification of both data transformations and visualizations, using a combination of direct manipulation and automated design. With a better understanding of users’ analysis behavior, we might improve the design of these visualization tools to promote effective outcomes. <br>
 +
 
 +
In this talk, I will present our recent work on characterizing the EVA process. We contribute a consistent definition of EVA through review of the relevant literature, and an empirical evaluation of existing assumptions regarding how analysts perform EVA. We present the results of a study where 27 Tableau users answered various analysis questions across 3 datasets. We measure task performance, identify recurring patterns across participants’ analyses, and assess variance from task specificity and dataset. We find striking differences between existing assumptions and the collected data. Participants successfully completed a variety of tasks, with over 80% accuracy across focused tasks with measurably correct answers. The observed cadence of analyses is surprisingly slow compared to popular assumptions from the database community. We find significant overlap in analyses across participants, showing that EVA behaviors can be predictable. Furthermore, we find few structural differences between open-ended and more focused analysis tasks. Finally, I will discuss the implications of our findings for the design of effective data analytics systems, and highlight several promising directions for future study.

<br> Abstract: Multi-touch devices are starting to replace PCs as the dominant form of computing, particularly for children. As a result, serious efforts are underway to investigate and integrate tablets into the classroom. Most of these research efforts are software agnostic, assuming that the current software ecology is sufficient to realize and study the potential of the hardware. In such a research mode, it is natural to think of tablets as personal devices since the vast majority of software is built around that premise (e.g., tablets as ebooks). Can they be more? Can tablets support collaborative learning?

<b>Visualization by Demonstration</b>
 +
<div class="mw-collapsible-content">
 +
<b>Abstract:</b> A commonly used interaction paradigm in most visualization tools is manual view specification. Tools implementing manual view specification often require users to manually specify visual properties through GUI operations on collections of visual properties and data attributes that are presented visually on control panels. To interact with tools implementing manual view specification users need to understand the potentially complex system parameters being controlled. Additionally, in such tools, users need to constantly shift their attention from the visual features of interest when interacting.  
 +
 
 +
In this talk, I present an alternative interaction paradigm for visualization construction and data exploration called visualization by demonstration. This paradigm advocates for a different process of visualization construction. I will also discuss the trade-offs between these interaction paradigms based on the data collected from an empirical study. I will then discuss applications of the "by demonstration’" paradigm in other areas in data visualization.  
 
<br>
 
<br>
 
<br>
 
<br>
In this talk, I present a vision of tablets as tiny tabletops to support at-device collaboration. We developed the Proportion iPad app to realize and study this vision. In Proportion, two children work at one tablet to complete a series of increasingly difficult ratio / proportion problems. In our studies at German primary schools (grade 4, age 9-11), we used Proportion to study the role of collaboration and multi-touch. I will present both early empirical findings across conditions and a case study of a particularly successful group.

<b>Dancing Pigs or Security? Measuring the Rationality of End-User Security Behavior</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: Using encryption tool is the only way to truly protect users’ confidentiality from third-party services. Although many encryption tools have been designed so far, they have been tested for usability either only in the lab or not at all. In this talk, we will present our research of usability about a particular encryption tool, called BrowserCrypt. First, we will talk about the overall design about this in-the-field study. Specifically, the usability of BrowserCrypt ignoring key management issue is detailed. Second, we will present our progress so far, including how BrowserCrypt works on Piazza and the data we have collected. Then, the challenges and limitations we encountered will be described, and our corresponding solutions will be proposed. Finally, we will introduce the future work.

<b>Abstract:</b> Accurately modeling human decision-making in security is critical to think about when, why, and how to recommend that users adopt certain secure behaviors. We used behavioral economics experiments to model the rationality of end-user security decision-making in a realistic online experimental system simulating a bank account. We ask participants to make a financially impactful security choice, in the face of transparent risks of account compromise and benefits offered by an optional security behavior (two-factor authentication). We find that more than 50% of our participants made rational (e.g., utility optimal) decisions, and we find that participants are more likely to behave rationally in the face of higher risk. Additionally, we confirm that users are boundedly rational: they make decisions based on some risks and context, but not others, and we can model their behavior well as a function of these factors. Finally, we show that a “one-size-fits-all” emphasis on security can lead to market losses, but that adoption by a subset of users with higher risks or lower costs can lead to market gains.

Designing Social Technologies for Creativity and Discovery
+
<b>Building Student Self-Awareness of Learning to Enhance Diversity in the Sciences</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: Computing has given rise to a wide range of software tools for supporting all stages of a creative process, from ideation and prototyping to disseminating finished creative works. More recently, these tools have begun to incorporate social elements, drawing on a growing body of research demonstrating the benefits of collaboration for enhancing creativity. Crowdsourcing platforms like Amazon's Mechanical Turk, which allow software developers to programmatically seek out human workers to complete online micro-tasks and integrate the results directly into a user interface, suggest exciting new opportunities to design social technologies that support creative processes. In this talk, I will describe some of my recent projects in this space. These include Pipeline, a tool for supporting leaders of artistic collaborations organized online; and CrowdCrit, a system that crowdsources critiques of visual designs and aggregates the results for designers. I will also present some preliminary work using social technologies to help solve historical mysteries. Throughout the talk, I will identify broader theoretical and design implications for social computing and creativity support tools.

<b>Abstract:</b> Many students are being left out of pursuing further studies in science because the current system of science education values students who learn via completion in an isolated, rather than collaborative way (Tobias, 1990). The stereotype of students who excel in science tend to be the ones who can conform to the institutional structure where the teacher is the sole source of knowledge (Friere, 2000). Through the idea of “Education as the Practice of Freedom” (hooks, 1994), the presentation will explain investigations that explore tangible ways to break down that stereotype. This research begins with the assumption that if teachers taught the ways science operates as a discipline, then students gain more power to construct their own scientific knowledge because they understand the “rules” of knowledge validation (Duschl, 1990). Learning how scientific knowledge is constructed and being self-aware of one’s own learning in science can help level the playing field so that students can do inquiry well (NRC, 1996; AAAS, 1993) and the science classroom will be a more inclusive, positive environment rather than relying on isolated competition for teaching. In this presentation, I will present an overview of research I have done over the past 10 years that focuses on helping students to become self-aware of their learning in science and how scientific knowledge is constructed. The work involves 8th grade students, undergraduates, graduate students, and professionals. The studies include constructs such as self-efficacy, motivation, metacognition, self-regulated learning, and visualization. Findings of the studies are synthesized into self-awareness priorities and how those constructs will ultimately impact social justice by providing more opportunities to see alternative perspectives and learn the “rules” of knowledge validation in science. As a result, students develop a sense of agency and an identity where anything is possible because they can learn independently in any situation.

SWARM: Sensing Whether Affect Requires Mediation
+
<b>The Problem of Designing for Subcultures</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: SWARM (Sensing Whether Affect Requires Mediation) is a wearable affective technology designed to allow a user to reflect on their own emotional state, help a user modify their affect, and help a user to interpret the emotional states of others. SWARM aims for a universal design (inclusive of people with various disabilities), with a focus on modular actuation components to accommodate users’ sensory capabilities and preferences, and a scarf form-factor meant to reduce the stigma of accessible technologies through a fashionable embodiment. Using an iterative, user-centered approach, this talk presents SWARM’s design and additionally contributes findings for best practices in creating personal emotion management systems, communicating emotions through technology actuations, wearable design techniques (including a modular soft circuit design technique that fuses conductive fabric with actuation components), and universal design considerations for wearable technology.

<b>Using Data and Technology to Save Endangered Species.</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: Finding the differences and similarities between two datasets is a common analytics task. With temporal event sequence data, this task is complex because of the many ways single events and event sequences can differ between the two datasets (or cohorts) of records: the structure of the event sequences (e.g., event order, co-occurring events, or event frequencies), the attributes of events and records (e.g., patient gender), or metrics about the timestamps themselves (e.g., event duration). In exploratory analyses, running statistical tests to cover all cases is time-consuming and determining which results are significant becomes cumbersome. Current analytics tools for comparing groups of event sequences emphasize a purely statistical or purely visual approach for comparison. This paper presents a taxonomy of metrics for comparing cohorts of temporal event sequences, showing that the problem-space is bounded. We also present a visual analytics tool, CoCo (for “Cohort Comparison”), which implements balanced integration of automated statistics with an intelligent user interface to guide users to significant, distinguishing features between the cohorts. Lastly, we describe two early case studies: the first with a research team studying medical team performance in the emergency department and the second with pharmacy researchers.

uCap: An Internet Data Management Tool for the Home
+
<b>Thinking, Autism and AGI</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: Internet Service Providers (ISPs) have introduced “data caps”, or quotas on the amount of data that a customer can download during a billing cycle. Under this model, Internet users who reach a data cap can be subject to degraded performance, extra fees, or even temporary interruption of Internet service. For this reason, users need better visibility into and control over their Internet usage to help them understand what uses up data and control how these quotas are reached. In this paper, we present the design and implementation of a tool, called uCap, to help home users manage Internet data. We conducted a field trial of uCap in 21 home networks in three countries and performed an in-depth qualitative study of ten of these homes. We present the results of the evaluation and implications for the design of future Internet data management tools.

<b>Abstract:</b> Despite recent advances in deep learning, we do not know yet how we can combine these application-specific models to build an artificial general intelligence (AGI).
<br/>
+
Furthermore, the data is becoming the bottleneck to scale these approaches for the multiple tasks. In this talk, I propose a theory of the thinking and a neural algorithm that can bootstrap intelligence with limited computational resources and data. This neural algorithm approximates the O(n3) parameter space of the thinking theory into the O(1) parameters to make learning tractable for the biological intelligent agents. I will explain this proposal by cognitive phenomenons that are observed in a human, such as infant language acquisition, visual and verbal thinking, personality, creativity, exploit-exploration trade off, dreaming, one-shot learning, abstract language.

<b>Shareable Dynamic Media: A revisit of the fundamentals of interactive computing</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: ([https://www.youtube.com/watch?v=cMGwNf90z28 Video Preview]) The building sector accounts for 41% of primary energy consumption in the US, contributing an increasing portion of the country’s carbon dioxide emissions. With recent sensor improvements and falling costs, auditors are increasingly using thermography—infrared (IR) cameras—to detect thermal defects and analyze building efficiency. Research in automated thermography has grown commensurately, aimed at reducing manual labor and improving thermal models. Though promising, we could find no prior work exploring the professional auditor’s perspectives of thermography or reactions to emerging automation. To address this gap, we present results from two studies: a semi-structured interview with 10 professional energy auditors, which includes design probes of five automated thermography scenarios, and an observational case study of a residential audit. We report on common perspectives, concerns, and benefits related to thermography and summarize reactions to our automated scenarios. Our findings have implications for thermography tool designers as well as researchers working on automated solutions in robotics, computer science, and engineering.

<b>Abstract:</b> Developing interactive systems that support collaboration between people, distribution across heterogeneous devices and user appropriation is notoriously difficult. Today’s software rests on a foundation built for personal computing, and to properly support the aforementioned qualities we need to revisit this foundation. In this talk, I will present you with a vision called Shareable Dynamic Media, inspired by Alan Kay’s seminal vision of Personal Dynamic Media. I will present a prototype implementation of the vision called Webstrates, and demonstrate how it enables the development of software where distribution across devices, collaboration between people, and malleability and reprogrammability are the norm rather than the exception. I will show our latest project, Codestrates, that combines Webstrates with the literate computing approach of interactive notebooks.

CHI Practice Talk: Personalized, Wearable Control of a Head-mounted Display for Users with Upper Body Motor Impairments

<b>Understanding User Tradeoffs for Search in Encrypted Communication</b>
 +
<br>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: Head-mounted displays provide relatively hands-free interaction that could improve mobile computing access for users with motor impairments. To investigate this largely unexplored area, we present two user studies. The first, smaller study evaluated the accessibility of Google Glass, a head-mounted display, with 6 participants. Findings revealed potential benefits of a head-mounted display yet demonstrated the need for alternative means of controlling Glass—3 of the 6 participants could not use it at all. We then conducted a second study with 12 participants to evaluate a potential alternative input mechanism that could allow for accessible control of a head-mounted display: switch-based wearable touchpads that can be affixed to the body or wheelchair. The study assessed input performance with three sizes of touchpad, investigated personalization patterns when participants were asked to place the touchpads on their body or wheelchair, and elicited subjective responses. All 12 participants were able to use the touchpads to control the display, and patterns of touchpad placement point to the value of personalization in providing support for each user’s motor abilities.

Abstract: End-to-end message encryption is the only way to achieve absolute message privacy. However, searching over
<!--<br/>
+
end-to-end encrypted messages is complicated. Several popular instant messaging tools (e.g., WhatsApp, iMessage) circumvent this inconvenience by storing the search index locally on the devices. Another approach, called searchable encryption, allows users to search encrypted messages without storing the search index locally. These approaches have inherent tradeoffs between usability and security properties, yet little is known about how general users value these tradeoffs, especially in the context of email rather than instant messaging. In this paper, we systematize these tradeoffs in order to identify key feature differences. We use these differences as the basis for a choice-based conjoint analysis experiment focused on email (n=160), in which participants make a series of choices between email services with competing features. The results allow us to quantify the relative importance of each feature. We find that users indicate high relative importance for increasing privacy and minimizing local storage requirements. While privacy is more important overall, local storage is more important than adding additional marginal privacy after an initial improvement. These results suggest that local indexing, which provides more privacy, may often be appropriate for encrypted email, but that searchable encryption, which limits local storage, may also hold promise for some users.

CHI Practice Talk: Trajectory Bundling for Animated Transitions
+
<b>Designing A Flexible Personal Data Tracking Tool</b>
 +
<br>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: Animated transition has been a popular design choice for smoothly switching between different visualization views or layouts, in which movement trajectories are created as cues for tracking objects during location shifting. Tracking moving objects, however, becomes difficult when their movement paths overlap or the number of tracking targets increases. We propose a novel design to facilitate tracking moving objects in animated transitions. Instead of simply animating an object along a straight line, we create "bundled" movement trajectories for a group of objects that have spatial proximity and share similar moving directions. To study the effect of bundled trajectories, we untangle variations due to different aspects of tracking complexity in a comprehensive controlled user study. The results indicate that using bundled trajectories is particularly effective when tracking more targets (six vs. three targets) or when the object movement involves a high degree of occlusion or deformation. Based on the study, we discuss the advantages and limitations of the new technique, as well as provide design implications.

<b>Abstract:</b> We now see an increasing number of self-tracking apps and wearable devices. Despite the vast number of available tools, however, it is still challenging for self-trackers to find apps that suit their unique tracking needs, preferences, and commitments. In this talk, I will present OmniTrack, a mobile self-tracking system, which enables self-trackers to construct their own trackers and customize tracking items to meet their individual tracking needs. OmniTrack leverages a semi-automated tracking approach that combines manual and automated tracking methods. From a deployment study, we showed how participants used OmniTrack to create, revise, and appropriate trackers—ranging from a simple mood tracker to a sophisticated daily activity tracker. I will discuss how to further improve OmniTrack by incorporating multimodal interactions, providing more appropriate visualizations on a mobile device, and supporting researchers' unique data collection needs.

CHI Practice Talk: BodyVis: A New Approach to Body Learning Through Wearable Sensing and Visualization

<b>Combining smartwatches with large displays for visual data exploration by Karthik Badam and Tom Horak</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: ([https://www.youtube.com/watch?v=3zh_yaslOnY Video Preview]) Internal organs are hidden and untouchable, making it difficult for children to learn their size, position, and function. Traditionally, human anatomy (body form) and physiology (body function) are taught using techniques ranging from worksheets to three-dimensional models. We present a new approach called BodyVis, an e-textile shirt that combines biometric sensing and wearable visualizations to reveal otherwise invisible body parts and functions. We describe our 15-month iterative design process including lessons learned through the development of three prototypes using participatory design and two evaluations of the final prototype: a design probe interview with seven elementary school teachers and three single- session deployments in after-school programs. Our findings have implications for the growing area of wearables and tangibles for learning.

<br> Abstract: A growing number of governments are opening their data to the general public. The hope is that citizens and business will be able to transform the data into insights, services, and products that will provide social and economic value. Grassroots organizations and non-profits have begun to make use of the data through the development of civic applications. In this talk I focus on a network of 48 city level organizations. I compare these organizations to the open-source software community. By analyzing GitHub repositories, I evaluate how many civic applications are being created, how many people are involved, and how many of these projects last. Finally I imagine how community design, collaboration tools, and crowdsourcing techniques could be leveraged to better support distributed analysis of open government data.

<b>Abstract</b>: Advances in artificial intelligence enable us to address key social issues. However, to see the benefit of this technology in many real-world applications, an integrative approach is necessary; effective solutions consist of a pipeline of processes or tasks involving both humans and machines. My research has integrated human computer interaction (HCI) techniques and data-driven methods applied to human data to steer technological innovations for people with visual impairments and for people who are deaf or hard-of-hearing. In this talk, I will provide an overview of my research program, and I will demonstrate the effectiveness of integrating machine learning and HCI methodologies with two concrete examples: i) teachable object recognizers trained by blind users, and ii) facial expression synthesis in sign language animations.

<br> Abstract: How do you launch a new program in an emerging field at an established design school  – data, information, and visualization. When the Maryland Institute College of Art (MICA) decided to create a new graduate program in Information Visualization, there was a document and a great deal of confidence that the program would help take the college in a new direction. This talk will tell the story of pits and perils of how the program moved from an idea, to launch, to bringing its fourth year of students, and how data, information, and visualization was the pilot, engineer, and passenger.

<b>Abstract</b>: International students are a rapidly growing sub-population of students, and the United States, as a top destination, has hosted students from 218 different countries. However, as with other international newcomers, these students face various types of challenges in a new country. Studies have reported the challenges this population faces in regard to cultures, academic systems, and general adjustments, but research is less clear about the challenges they face in terms of information behaviors during adjustment to a new country. This study addresses the information behaviors of international newcomer students in the context of adjustment to new local environments; that is, their local information behavior (LIB). Specifically, drawing on prior work and theories, this research conceptualizes the idea of "socio-national context," the degree to which there are individuals from the same country available in one's local environment, as a factor influencing international newcomer students’ information behavior. Through the findings from this longitudinal mixed-method study of international and U.S. graduate students in different socio-national contexts, it is argued that information behavior theories and models need to account for people's socio-national contexts if they are to inform research involving international newcomer students and provide insights on designing systems and services for all international newcomer students, especially those from countries that tend to be less well-represented among international students in a host country.

Social Information Spaces: Designing for Smart(er) Societies

<b>Rethinking technology for dementia</b>
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: People are pretty smart. When someone uses bad information, it’s often because the tools they use to find that information were not designed to support good assessments. The need for an integrated HCI response to the problem of information assessment is critical in an age of participatory information sources like Wikipedia, Wikia sites, Reddit, and Ancestry.com. These are information sources produced and curated by thousands of contributors using collaboration or aggregation platforms. Such technologies can be designed to support human needs in different ways; for example, they can be designed using well-understood principles of usability, accessibility, or ergonomics. However, HCI currently lacks a shared vocabulary for talking about “assessability” — those properties of designed spaces that allow people to make good judgments about the information they encounter there. Assessable designs don’t just deliver assessments of information quality, but support people in getting *better* at judging the information they encounter online.

<b>Abstract</b>: As the population ages, research is increasingly focused on conditions associated with growing older, such as cognitive and physical impairment. Technology is often presented as a solution for managing or treating these changes. This framing can position health conditions as problems to address through design and can neglect the complexity and positive aspects of older adulthood. In this talk, I draw on critical perspectives from Human-Computer Interaction and Gerontology. I describe ways in which technology can help us understand and challenge stereotypes around aging as well as cognitive impairment, and my ongoing and future work in this area. I will argue for a view of aging that takes into account the ways that technologies position older individuals and, in turn, the way that this view can inform the design of new technologies to enrich the experience of growing older.

<b>Back to the Future: How people construct new creative ideas from old knowledge, and how technology can help</b>
coming out of the ALMA telescope
 
 
<div class="mw-collapsible-content">
 
<div class="mw-collapsible-content">
<br> Abstract: [http://en.wikipedia.org/wiki/Atacama_Large_Millimeter_Array ALMA telescope] is a large radio interferometer in Chile, operated by a large international consortium (Europe, North America, and Japan), and is starting to show groundbreaking new science. The data products will be delivered a series of large data cubes, requiring detailed analysis to get down to the real science. I will explain the ALMA data format, and what we are proposing to do to extract science and visualize these complex results to the user. We have played with some GUI designs, but decided on a pragmatic approach, to adopt and adapt an existing web interface that ALMA is using. We are looking forward to your feedback and suggestions to improve the design.

<b>Abstract:</b> Where do good ideas come from? One answer is that they come from prior knowledge: for example, Thomas Edison leveraged his knowledge of phonographs to “do for the eye what the phonograph does for the ear”. Yet, much research on human creativity demonstrates that prior knowledge often constrains creativity. How do people construct new creative ideas from old knowledge? And (how) can technology help? In the first part of my talk, I will summarize empirical work I have done that advances theories of the conditions under which people successfully construct new creative ideas from prior knowledge. This empirical work shows that prior knowledge can inspire creativity when it is analogically related to the current problem. This insight informs the ongoing work I will discuss in the second part of my talk: developing information technologies that combine human and machine intelligence to more effectively support analogical reasoning over prior knowledge.

The User Experience of Viewing Captioned Content
Much has been made of the ability of automatic speech recognition (ASR) to supplement or replace human captioners both for video content and for live meetings. While the word error rate of ASR has been steadily improving, and on some types of content can even beat out human captioners, these improvements do not automatically in a good user experience for people who are deaf or hard of hearing. In this talk we will examine the reasons why this is so, and provide an overview of current efforts to develop human-centered caption quality metrics that are more closely aligned with meeting the needs of people who depend on captions to consume content.

Promoting Pro-social Behavior with End-to-End Data Science
The recent development of data science methods, including large-scale machine learning and causal inference, has presented a game-changing opportunity for social good provision through the effort of the crowd. In this talk, I introduce an end-to-end data science pipeline to promote behavioral change for pro-social benefits. More specifically, this involves conducting causal data analysis on empirical data for actionable insights and robust prediction models, incorporating the insights and predictions in designing recommender systems for individual actions, and evaluating the effectiveness of the recommender systems in promoting behavioral changes with randomized field experiments. I will present two applications of the end-to-end pipeline, where we designed and deployed team recommender systems on an online microfinance platform (Kiva.org) and a ride-sharing platform (DiDi). We evaluated the recommender systems through large-scale field experiments, which show significant increases in user participation. The recommender system has been deployed in DiDi and has impacted millions of users in practice.

Quantifying Human Performance and the Quality of Immersive Experiences
Psychometric evaluations are generally used to understand the Quality of Experience (QoE) of immersive environments produced using augmented/mixed/virtual reality. Typically, these subjective evaluations are done from an end-user point-of-view, but these are limited by the subjective observations due to a number of factors. The objective approach consists of measuring the QoE by monitoring the network technical parameters or the network Quality of Service (QoS), such as throughput, delay, and packet loss. Most of the research on objective approaches for QoS-QoE mapping have focused on video streaming. Such objective QoS-QoE mapping strategies cannot be directly applied for immersive environments. Hence, in this talk, we address two related questions: (1) Can we identify metrics that can objectively quantify the performance of an immersive environment? (2) Can we use the above objective performance metrics to understand the possible user QoE without the need for subjective user study or with minimal user study? We start with different examples of immersive environments such as haptic-enabled applications, mirror therapy, and games. We discuss what metrics are influenced by different system parameters such as processing power, and network QoS. Then, we present some of our preliminary work on understanding users’ QoE through these metrics.

Celestial: Color Patterns for improving Color Perception for blind people.
It is relatively difficult to recreate the abstract three-dimensional shape with only the tactile sense. Gibson said "These abilities can be improved through practice." "When you touch something, You may have no idea about it at first touch, but as you continue touching, you soon will know vaguely what it is" , Kojiro Hirose said.

Recently, we developed "Blind-touch" to aid the visually impaired to appreciate greater painter’s work of art. This work is a reproduction of an existing masterpiece by means of a 3D printer and haptic electronics. It recognizes the pattern by touching the object in the artwork with a fingertip, and voice explanation and sound effect are provided through the voice user interface. Color is an equaling lens through which we experience the natural and digital realities. Now, we are exploring the tactile-color association based on semiotics to represent colors with fingertip tactile sensation. In this way, audio and touch contribute information to the non-visual perception of color in an complementary manner. In this talk, we review the related works and introduce a so-called “Celestial color tactile pattern” built based on the concept of both pictogram and ideogram and its variants.

Human-Centered Artificial Intelligence: Designing Next Generation User Experiences
The next generation of user experiences will produce 1000-fold improvements in human capabilities. These new tools will amplify, augment, enhance, and empower people, just as the Web, email, search, navigation, digital photography, and many other applications have already done. These new human-centered tools will produce comprehensible, predictable, and controllable applications that promote self-efficacy and social participation at scale. The goal is to ensure human control, while increasing the level of automation. In short, the next generation of tools will make more people, more creative, more often.
Improved designs will give billions of users comprehensible interfaces that hide the underlying complexity of advanced algorithms. Users will see familiar visual strategies based on direct manipulation to provide informative feedback about the machine’s state and what they can do. Every use will build confidence that users can reliably accomplish their goals and increase the trust that the machine is under their control.

MakeCode and CODAL: intuitive and efficient embedded systems programming for education
Across the globe, it is now commonplace for educators to engage in the making (design and development) of embedded systems in the classroom to motivate and excite their students. This new domain brings its own set of unique requirements. Historically, embedded systems development requires knowledge of low-level programming languages, local installation of compilation toolchains, device drivers, and applications. For students and educators, these requirements can introduce insurmountable barriers.
We present the motivation, requirements, implementation, and evaluation of a new programming platform that enables novice users to create software for embedded systems. The platform has two major components:
1) Microsoft MakeCode (www.makecode.com), a web app that encapsulates an entire beginner IDE for microcontrollers; and
2) CODAL, an efficient component-oriented C++ runtime for microcontrollers.
We show how MakeCode and CODAL provide an accessible, cross-platform, installation-free programming experience for the BBC micro:bit and other embedded devices.

Towards Automated Fact Discovery and Ranking
In this talk, I present the work of finding new, prominent situational facts, which are emerging statements about objects that stand out within certain contexts. Many such facts are newsworthy—e.g., an athlete’s outstanding performance in a game, or a viral video’s impressive popularity. Effective and efficient identification of these facts assists journalists in reporting, one of the main goals of computational journalism. A situational fact can be modeled as a “contextual” tuple that stands out against historical tuples in a context, specified by a conjunctive constraint involving dimension attributes when a set of measure attributes are compared. New tuples are constantly added to the table, reflecting events happening in the real world. Our goal is to discover constraint-measure pairs that qualify a new tuple as a contextual significant tuple, and discover them quickly before the event becomes yesterday’s news.

Diversity in Matching Markets
In bipartite matching problems, vertices on one side of a bipartite graph are paired with those on the other. In its offline variant, both sides of the graph are known a priori; in its online variant, one side of the graph is available offline, while vertices on the other arrive online and are irrevocably and immediately matched (or ignored) by an algorithm. Examples of such problems include matching workers to firms, advertisers to keywords, organs to patients, and riders to rideshare drivers. Much of the literature focuses on maximizing the total relevance---modeled via total weight---of the matching. However, in many real-world problems, it is also important to consider the contribution of diversity: hiring a diverse pool of candidates, displaying a relevant but diverse set of ads, and so on.

In this talk, we model the promotion of diversity in matching markets via maximization of a submodular function over the set of matched edges. We present new results in a generalization of traditional offline matching, b-matching, where vertices have both lower and upper bounds on the number of adjacent matched edges. We also present new theoretical results in online submodular bipartite matching. Finally, we conclude with ongoing work that approaches the problem of hiring a diverse cohort of workers through the lens of combinatorial pure exploration (CPE) in the multiarmed bandit setting, and discuss an ongoing experiment in this space at a large research university.

This talk will cover joint work with Saba Ahmadi, Faez Ahmed, Samsara Counts, Jeff Foster, Mark Fuge, Samir Khuller, Zhi Lang, Nicholas Mattei, Karthik A. Sankararaman, Candice Schumann, Aravind Srinivasan, and Pan Xu.

What is Valuing vs “Jerk” Behavior? How behavior impacts a positive working experience
Women in tech leave the field at twice the quit rate as men. Women often state, and research confirms, that women don’t feel valued. They point to the culture of the organization and how they are treated as a contributing factor. They say that men are “bro’s” or “jerks.” In 2018, we launched the Valuing & Jerk Project as one WITops initiative (https://www.witops.org). This talk will present our findings and perspective. Behavior creates or undermines connection and value. The Valuing and Jerk Project focuses on understanding which behaviors are experienced as valuing in everyday work and which result in naming the other as a “jerk”. Using Contextual Inquiry, we have uncovered core valuing behaviors, what devaluing means, and where behavior crosses the line to become “jerk” behavior. Armed with this understanding our next step is to generate and test interventions and solutions. The talk will introduce the Valuing and Jerk Project.

Designing to Support People with Cognitive and Learning Disabilities
Have you ever wondered how to create websites, applications, and content that support individuals with cognitive and learning disabilities; individuals who are aging; or individuals who are tired, overworked, and distracted? The W3C Cognitive and Learning Disabilities Accessibility (COGA) Task Force has been working on a design guide that goes beyond WCAG 2.2 to support individuals with cognitive and learning disabilities. The resulting design patterns and guidance bridges accessibility and usability and support a much wider audience than just those with disabilities. Rachael will present her perspectives as an invited expert on this work. Please come learn about the design patterns and how to provide input on this evolving document.

Underestimating the challenge of cognitive disabilities (and digital literacy). Directions to explore in short, medium and long term.
Recent work has caused us to question our understanding of the challenge of digital access by people with cognitive disabilities. Our underestimation may, in part, help explain our difficulties as a field to date. In part, it has exposed what may be a much wider problem than we understood, and one that goes beyond those we have thought of as having cognitive disabilities. It intersects with digital literacy but also has implications for those with other disabilities as well. The concept of Technology Quotient (TQ) will be discussed and approaches for addressing access by people with cognitive disabilities and low digital literacy today, tomorrow and in the future will be explored in this talk.

Human Factors in Mobile Authentication
Mobile authentication is a crucial component of authentication more broadly, especially as mobile devices become evermore connected to the broader computer security ecosystem. The overarching goal of my research is to improve the current state of mobile authentication by taking a holistic approach to measuring mobile authentication and its impacts that intersect directly with the user experience. In this talk, I will present a narrative of contributions to mobile authentication over the last 10 years, focusing on how human factors impact the security, from attacks, choices, and perceptions. I will particularly focus on one form of mobile authentication, Android's graphical pattern unlock, which may be the most heavily used graphical authentication system, ever. Based on my experience, I will also present some new directions and methods that can improve the security of mobile authentication and some new results on PINs and LG's graphical Knock Code Authentication.

Storytelling makes research data come to life
We all love our user research data…but why is it such a struggle to use the insights we uncover to create direction for a project? Storytelling is the missing link, getting past charts and graphs to dig into what the data means for meeting human needs and making something usable and useful. Whitney will show how stories put research insights into context, communicate the entire user journey, show problems through the eyes of your users, and help you ask better questions (and run better usability tests) to gain deeper insights. Whitney is the co-founder of the Center for Civic Design, approaching democracy as a design problem, so there will be examples from the challenges of designing elections as well as stories from her work in theatre.

Design Democratization in the Age of Machine Learning.
Design democratization can transform the way we think about designing products. However, to enable design democratization, we need machine learning and computing methods to enable organizations to process a large amount of information efficiently. Using the example of online design contests, we will discuss three problems which organizations face in conducting design contests: a) How does one form teams to evaluate design ideas? b) How does one filter high quality and diverse ideas out of hundreds of submissions? and c) How does one reliably measure the creativity of ideas? We will discuss how matching, ranking, and novelty estimation methods developed in our work address these issues and what challenges remain for the field.

Interactive Fabrication and Fabrication for Interaction.
3D printing technology has been widely applied to produce well-designed objects. There is a hope to make both the modeling process and printing outputs more interactive, so that designers can get in-situ tangible feedback to fabricate objects with rich functionalities. To date, however, knowledge accumulated to realize this hope remains limited. In this talk, I will present two lines of research. The first line of work aims at facilitating an interactive process of fabrication. I demonstrate novel interactive fabrication systems that allow the designer to create 3D models in AR with a robotic arm to print the model in real time and on-site. The second line of work concerns the fabrication of 3D printed objects that are interactive. I report new techniques for 3D printing with novel materials such as fabric sheet, and how to print one-off functional objects such as sensor and motor. I will conclude the talk by outlining future research directions built upon my current work.

Everyone a Data Scientist: Empowering Casual Users to Understand Complex Data.
Understanding data is quickly becoming the new digital divide. Merely having access to information and communication technologies (ICTs) is no longer sufficient when our society is overflowing with massive volumes of raw, complex, and heterogeneous data. Since best-practice data science workflows are still only available through esoteric software libraries, typically accessed using the Python and R languages, leveraging this data to its full potential often requires significant programming expertise. Even commercial point-and-click analytics tools such as Tableau, Spotfire, and QlikView require training and assume significant prior knowledge of mathematical, statistical, and sometimes even machine learning concepts. This means that currently only people who have the appropriate data and technology literacy can harness the ready availability of data in our society.

In this work-in-progress talk, I will discuss our efforts for shrinking or outright eliminating this new digital data divide through interactive visualization, explainable machine learning, and collaborative technologies. More specifically, I will talk about several past, current, or planned projects on this topic, including (1) the use of mixed-initiative interaction, which combines both human and computational efforts in the analytical process; (2) the use of attention for computational steering; (3) recommender systems for automatically suggesting the next analytical step in a workflow; (4) direct manipulation methods for interacting with machine learning models; and (5) "team-first" collaborative mechanisms that reduce the barrier to synchronizing and sharing work to facilitate emergent collaboration. This is ongoing research, so your feedback on these efforts is welcome.

Join, Stay or Go? Members’ Life Cycles in Online Health Communities
This talk discusses temporal changes in members’ participation in online health community (OHC), focusing on their motivations for joining and changes in their motivations as they transition to other roles or ultimately leave the community. We use mixed methods, combining behavioral log analysis, automated content analysis, surveys and interviews. We found that members started participating in OHCs for a common set of reasons, mainly to acquire support and to perform social comparisons. When their need for support decreased, most members quit the site. The motivations of those who stayed shifted to providing support and helping other members in the community. Oldtimers also established social ties with others members, which motivated them to stay in the community. These oldtimers, who contributed the majority of content, encountered challenges that threatened their commitment to the community, including negative emotion related to other members’ deaths. These challenges led them to take leaves of absence from the community or to drop out permanently. Our findings shed light on the changing motivations of OHC members, which provide implications for better designing OHCs.

ORC Layout: Adaptive GUI Layout with OR-Constraints

We propose a novel approach for constraint-based graphical user interface (GUI) layout based on OR-constraints (ORC) in standard soft/hard linear constraint systems. ORC layout unifies grid layout and flow layout, supporting both their features as well as cases where grid and flow layouts individually fail. We describe ORC design patterns that enable designers to safely create flexible layouts that work across different screen sizes and orientations. We also present the ORC Editor, a GUI editor that enables designers to apply ORC in a safe and effective manner, mixing grid, flow and new ORC layout features as appropriate. We demonstrate that our prototype can adapt layouts to screens with different aspect ratios with only a single layout specification, easing the burden of GUI maintenance. Finally, we show that ORC specifications can be modified interactively and solved efficiently at runtime.

It's all about creating new possibilities for people: A journey from the lab to a startup

One of the most valuable parts of the DNA of HCIL is its focus on "human", and how our mentors guide us to connect our work with people (users). As a student of this school of thought, I had found my purpose to help the 95% by identifying, questioning, and removing barriers (creating opportunities) in visual analytics. Two years ago, with results baked in lab, and the same driving purpose, I stepped into a world unknown to me: creating, running, and growing a business, one customer at a time.

I am back to share some of the surprises, new perspectives, and validations from this journey so far. What I missed can help you realize the opportunities you already have. What I wish I knew may reveal some gaps. And, what remained constant may hint that research in university and what comes after may not be so different after all. I also will touch on the subtle and dynamic balance between your elevator pitch, your audience, the value you provide, and crossing the finish line.

Information Olfactation: Harnessing Scent to Convey Data
Olfactory feedback for analytical tasks is a virtually unexplored area in spite of the advantages it offers for information recall, feature identification, and location detection. We have introduced the concept of information olfactation as the fragrant sibling of information visualization, and this talk will cover our theoretical model of how scent can be used to convey data. Building on a review of the human olfactory system and mirroring common visualization practice, we propose olfactory marks, the substrate in which they exist, and their olfactory channels that are available to designers. To exemplify this idea, we present viScent: A six-scent stereo olfactory display capable of conveying olfactory glyphs of varying temperature and direction, as well as a corresponding software system that integrates the display with a traditional visualization display, along with three applications that make use of the viScent system.

Learning in the Holodeck: the Role of Multisensory Cues on Pattern Recognition in VR
Designing for multiple senses has the capacity to improve virtual realism, extend our ability to process information, and more easily transfer knowledge between physical and digital environments. HCI researchers are beginning to explore the viability of integrating multisensory media (“multimedia”) into virtual experiences, however research has yet to consider whether mulsemedia truly enhances pattern recognition in virtual reality (VR). In the context of citizen science watershed habitat training, our research asks, how does realism affect observation skills in VR? Within this domain, we build a multisensory system that allows users to feel (wind, thermal, humidity) and smell landscape and environmental conditions. We then compare and report on how users make observations and infer patterns between 2 stream habitats in VR, with and without the multisensory information. Our findings reveal that multisensory information improved the number of high-level, mid-level and low-level observations participants made, and positively impacted engagement and immersion.

A Characterization Study of Exploratory Analysis Behaviors in Tableau
Exploratory visual analysis (EVA) is an interactive process comprising both focused tasks and more open-ended exploration. Visual analysis tools aim to facilitate this process by enabling rapid specification of both data transformations and visualizations, using a combination of direct manipulation and automated design. With a better understanding of users’ analysis behavior, we might improve the design of these visualization tools to promote effective outcomes.

In this talk, I will present our recent work on characterizing the EVA process. We contribute a consistent definition of EVA through review of the relevant literature, and an empirical evaluation of existing assumptions regarding how analysts perform EVA. We present the results of a study where 27 Tableau users answered various analysis questions across 3 datasets. We measure task performance, identify recurring patterns across participants’ analyses, and assess variance from task specificity and dataset. We find striking differences between existing assumptions and the collected data. Participants successfully completed a variety of tasks, with over 80% accuracy across focused tasks with measurably correct answers. The observed cadence of analyses is surprisingly slow compared to popular assumptions from the database community. We find significant overlap in analyses across participants, showing that EVA behaviors can be predictable. Furthermore, we find few structural differences between open-ended and more focused analysis tasks. Finally, I will discuss the implications of our findings for the design of effective data analytics systems, and highlight several promising directions for future study.

Visualization by Demonstration

Abstract: A commonly used interaction paradigm in most visualization tools is manual view specification. Tools implementing manual view specification often require users to manually specify visual properties through GUI operations on collections of visual properties and data attributes that are presented visually on control panels. To interact with tools implementing manual view specification users need to understand the potentially complex system parameters being controlled. Additionally, in such tools, users need to constantly shift their attention from the visual features of interest when interacting.

In this talk, I present an alternative interaction paradigm for visualization construction and data exploration called visualization by demonstration. This paradigm advocates for a different process of visualization construction. I will also discuss the trade-offs between these interaction paradigms based on the data collected from an empirical study. I will then discuss applications of the "by demonstration’" paradigm in other areas in data visualization.

Dancing Pigs or Security? Measuring the Rationality of End-User Security Behavior

Abstract: Accurately modeling human decision-making in security is critical to think about when, why, and how to recommend that users adopt certain secure behaviors. We used behavioral economics experiments to model the rationality of end-user security decision-making in a realistic online experimental system simulating a bank account. We ask participants to make a financially impactful security choice, in the face of transparent risks of account compromise and benefits offered by an optional security behavior (two-factor authentication). We find that more than 50% of our participants made rational (e.g., utility optimal) decisions, and we find that participants are more likely to behave rationally in the face of higher risk. Additionally, we confirm that users are boundedly rational: they make decisions based on some risks and context, but not others, and we can model their behavior well as a function of these factors. Finally, we show that a “one-size-fits-all” emphasis on security can lead to market losses, but that adoption by a subset of users with higher risks or lower costs can lead to market gains.

Building Student Self-Awareness of Learning to Enhance Diversity in the Sciences

Abstract: Many students are being left out of pursuing further studies in science because the current system of science education values students who learn via completion in an isolated, rather than collaborative way (Tobias, 1990). The stereotype of students who excel in science tend to be the ones who can conform to the institutional structure where the teacher is the sole source of knowledge (Friere, 2000). Through the idea of “Education as the Practice of Freedom” (hooks, 1994), the presentation will explain investigations that explore tangible ways to break down that stereotype. This research begins with the assumption that if teachers taught the ways science operates as a discipline, then students gain more power to construct their own scientific knowledge because they understand the “rules” of knowledge validation (Duschl, 1990). Learning how scientific knowledge is constructed and being self-aware of one’s own learning in science can help level the playing field so that students can do inquiry well (NRC, 1996; AAAS, 1993) and the science classroom will be a more inclusive, positive environment rather than relying on isolated competition for teaching. In this presentation, I will present an overview of research I have done over the past 10 years that focuses on helping students to become self-aware of their learning in science and how scientific knowledge is constructed. The work involves 8th grade students, undergraduates, graduate students, and professionals. The studies include constructs such as self-efficacy, motivation, metacognition, self-regulated learning, and visualization. Findings of the studies are synthesized into self-awareness priorities and how those constructs will ultimately impact social justice by providing more opportunities to see alternative perspectives and learn the “rules” of knowledge validation in science. As a result, students develop a sense of agency and an identity where anything is possible because they can learn independently in any situation.

Thinking, Autism and AGI


Abstract: Despite recent advances in deep learning, we do not know yet how we can combine these application-specific models to build an artificial general intelligence (AGI). Furthermore, the data is becoming the bottleneck to scale these approaches for the multiple tasks. In this talk, I propose a theory of the thinking and a neural algorithm that can bootstrap intelligence with limited computational resources and data. This neural algorithm approximates the O(n3) parameter space of the thinking theory into the O(1) parameters to make learning tractable for the biological intelligent agents. I will explain this proposal by cognitive phenomenons that are observed in a human, such as infant language acquisition, visual and verbal thinking, personality, creativity, exploit-exploration trade off, dreaming, one-shot learning, abstract language.

Shareable Dynamic Media: A revisit of the fundamentals of interactive computing

Abstract: Developing interactive systems that support collaboration between people, distribution across heterogeneous devices and user appropriation is notoriously difficult. Today’s software rests on a foundation built for personal computing, and to properly support the aforementioned qualities we need to revisit this foundation. In this talk, I will present you with a vision called Shareable Dynamic Media, inspired by Alan Kay’s seminal vision of Personal Dynamic Media. I will present a prototype implementation of the vision called Webstrates, and demonstrate how it enables the development of software where distribution across devices, collaboration between people, and malleability and reprogrammability are the norm rather than the exception. I will show our latest project, Codestrates, that combines Webstrates with the literate computing approach of interactive notebooks.

Bio: Clemens Nylandsted Klokmose is an associate professor in the development of advanced interactive systems at the Department of Digital Design and Information Studies, at the School of Communication and Culture, Aarhus University.

Clemens’ main interest is the fundamentals of interactive computing, particularly to support and understanding computing with multiple devices and multiple people. Many of his ideas are crystallised into the Webstrates platform (webstrates.net), which he leads the development of.

Understanding User Tradeoffs for Search in Encrypted Communication

Abstract: End-to-end message encryption is the only way to achieve absolute message privacy. However, searching over end-to-end encrypted messages is complicated. Several popular instant messaging tools (e.g., WhatsApp, iMessage) circumvent this inconvenience by storing the search index locally on the devices. Another approach, called searchable encryption, allows users to search encrypted messages without storing the search index locally. These approaches have inherent tradeoffs between usability and security properties, yet little is known about how general users value these tradeoffs, especially in the context of email rather than instant messaging. In this paper, we systematize these tradeoffs in order to identify key feature differences. We use these differences as the basis for a choice-based conjoint analysis experiment focused on email (n=160), in which participants make a series of choices between email services with competing features. The results allow us to quantify the relative importance of each feature. We find that users indicate high relative importance for increasing privacy and minimizing local storage requirements. While privacy is more important overall, local storage is more important than adding additional marginal privacy after an initial improvement. These results suggest that local indexing, which provides more privacy, may often be appropriate for encrypted email, but that searchable encryption, which limits local storage, may also hold promise for some users.

Bio: Wei Bai is a PhD student in the Department of Electrical and Computer Engineering at the University of Maryland, advised by Prof. Michelle L. Mazurek. His research interests include network security and privacy with an emphasis on human factors, and his dissertation is about user perceptions of and attitudes toward encrypted communication.

Designing A Flexible Personal Data Tracking Tool

Abstract: We now see an increasing number of self-tracking apps and wearable devices. Despite the vast number of available tools, however, it is still challenging for self-trackers to find apps that suit their unique tracking needs, preferences, and commitments. In this talk, I will present OmniTrack, a mobile self-tracking system, which enables self-trackers to construct their own trackers and customize tracking items to meet their individual tracking needs. OmniTrack leverages a semi-automated tracking approach that combines manual and automated tracking methods. From a deployment study, we showed how participants used OmniTrack to create, revise, and appropriate trackers—ranging from a simple mood tracker to a sophisticated daily activity tracker. I will discuss how to further improve OmniTrack by incorporating multimodal interactions, providing more appropriate visualizations on a mobile device, and supporting researchers' unique data collection needs.

Accessibility and Assistive Technologies at the Intersection of Users and Data

Abstract: Advances in artificial intelligence enable us to address key social issues. However, to see the benefit of this technology in many real-world applications, an integrative approach is necessary; effective solutions consist of a pipeline of processes or tasks involving both humans and machines. My research has integrated human computer interaction (HCI) techniques and data-driven methods applied to human data to steer technological innovations for people with visual impairments and for people who are deaf or hard-of-hearing. In this talk, I will provide an overview of my research program, and I will demonstrate the effectiveness of integrating machine learning and HCI methodologies with two concrete examples: i) teachable object recognizers trained by blind users, and ii) facial expression synthesis in sign language animations.

Small Worlds in a Distant Land: International Newcomer Students' Local Information Behavior in Unfamiliar Environments

Abstract: International students are a rapidly growing sub-population of students, and the United States, as a top destination, has hosted students from 218 different countries. However, as with other international newcomers, these students face various types of challenges in a new country. Studies have reported the challenges this population faces in regard to cultures, academic systems, and general adjustments, but research is less clear about the challenges they face in terms of information behaviors during adjustment to a new country. This study addresses the information behaviors of international newcomer students in the context of adjustment to new local environments; that is, their local information behavior (LIB). Specifically, drawing on prior work and theories, this research conceptualizes the idea of "socio-national context," the degree to which there are individuals from the same country available in one's local environment, as a factor influencing international newcomer students’ information behavior. Through the findings from this longitudinal mixed-method study of international and U.S. graduate students in different socio-national contexts, it is argued that information behavior theories and models need to account for people's socio-national contexts if they are to inform research involving international newcomer students and provide insights on designing systems and services for all international newcomer students, especially those from countries that tend to be less well-represented among international students in a host country.

Rethinking technology for dementia

Abstract: As the population ages, research is increasingly focused on conditions associated with growing older, such as cognitive and physical impairment. Technology is often presented as a solution for managing or treating these changes. This framing can position health conditions as problems to address through design and can neglect the complexity and positive aspects of older adulthood. In this talk, I draw on critical perspectives from Human-Computer Interaction and Gerontology. I describe ways in which technology can help us understand and challenge stereotypes around aging as well as cognitive impairment, and my ongoing and future work in this area. I will argue for a view of aging that takes into account the ways that technologies position older individuals and, in turn, the way that this view can inform the design of new technologies to enrich the experience of growing older.

Bio: Amanda Lazar is an Assistant Professor in the College of Information studies at the University of Maryland, College Park. Her research is in the areas of Human-Computer Interaction and Health Informatics. She studies how technologies designed for health and wellbeing position and support marginalized populations.

Back to the Future: How people construct new creative ideas from old knowledge, and how technology can help

Abstract: Where do good ideas come from? One answer is that they come from prior knowledge: for example, Thomas Edison leveraged his knowledge of phonographs to “do for the eye what the phonograph does for the ear”. Yet, much research on human creativity demonstrates that prior knowledge often constrains creativity. How do people construct new creative ideas from old knowledge? And (how) can technology help? In the first part of my talk, I will summarize empirical work I have done that advances theories of the conditions under which people successfully construct new creative ideas from prior knowledge. This empirical work shows that prior knowledge can inspire creativity when it is analogically related to the current problem. This insight informs the ongoing work I will discuss in the second part of my talk: developing information technologies that combine human and machine intelligence to more effectively support analogical reasoning over prior knowledge.

Bio: Joel Chan is an Assistant Professor in the University of Maryland’s College of Information Studies (iSchool), and Human-Computer Interaction Lab (HCIL). His research and teaching focus on the intersection of people, information, and creativity. He wants to know how they (can best) combine to enable us to design the future(s) we want to live in. His work has been recognized with a Best Paper Award at the ASME Design Theory and Methodology conference, the Design Studies Award 2015, and supported by an NSF Doctoral Dissertation Improvement Grant. Previously, he was a Postdoctoral Research Fellow and Project Scientist in the Human-Computer Interaction Institute at Carnegie Mellon University. He received his PhD in Cognitive Psychology at the University of Pittsburgh.

WILDLABS.NET: the conservation technology network

Abstract: WILDLABS.NET: the conservation technology network is a collaboration across organizations that provides online infrastructure to connect wildlife conservationists directly to technologists to support the informed integration of technology tools in conservation practice. Since 2015, WILDLABS has evolved into a thriving online community of over 2,300 experts around the globe who crowd-source ideas and information, share case studies and co-develop solutions to pressing conservation and research challenges. WILDLABS community members range from academics to tech sector professionals, NGO staff, field-based practitioners and makers. On our platform, ideas are shared in over 25 technology and conservation challenge-specific groups with over 450 active discussion threads. The community is also a hub for posting grant and job opportunities to enhance the uptake of technical expertise into wildlife conservation initiatives. In this talk, we’ll explore the latest happenings on WILDLABS and empower those with engineering and related expertise to share their abilities to help save species.
