<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> A panel discussion on approaches to reviewing research papers.</b> | |||
<br> | |||
In light of the approaching deadline for SIGCHI 2020, Professors Niklas Elmqvist, Amanda Lazar, and Joel Chan will discuss the why/how of giving feedback on drafts of research papers. This would be helpful for anyone (Undergrad, Masters, or PhD students) who might be thinking of volunteering to review for conferences, ACM SIGCHI, or even for other lab members in the HCIL’s very own CHI clinic. Reviewers of all levels of expertise, even if you’ve never reviewed a research paper, are encouraged to participate and ask questions during the discussion.

<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 & 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> 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>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> | |||

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. | |||

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.
