Ubiquitous Analytics: Interacting with Big Data Anywhere, Anytime
<div class="mw-collapsible-content">
<br> Abstract: Computing is becoming increasingly embedded in our everyday lives: mobile devices are growing smaller yet more powerful, large displays are getting cheaper, and our physical environments are turning intelligent and are integrating an increasing number of digital processors. Meanwhile, data is everywhere, and people need to leverage all of this digital infrastructure to turn it into actionable information about their hobbies, health, and personal interest. In this talk, I will present the concept of ubiquitous analytics that is staking out a new digital future of ever-present, always-on computing; one that can support manipulating, thinking about, and interacting with data anytime, anywhere.

UIST2014 Practice Talk: Tohme: Detecting Curb Ramps in Google Street View Using Crowdsourcing, Computer Vision, and Machine Learning
<div class="mw-collapsible-content">
<br> Building on recent prior work that combines Google Street View (GSV) and crowdsourcing to remotely collect information on physical world accessibility, we present the first “smart” system, Tohme, that combines machine learning, computer vision (CV), and custom crowd interfaces to find curb ramps remotely in GSV scenes. Tohme consists of two workflows, a human labeling pipeline and a CV pipeline with human verification, which are scheduled dynamically based on predicted performance. Using 1,086 GSV scenes (street intersections) from four North American cities and data from 403 crowd workers, we show that Tohme performs similarly in detecting curb ramps compared to a manual labeling approach alone (F-measure: 84% vs. 86% baseline) but at a 13% reduction in time cost. Our work contributes the first CV-based curb ramp detection system, a custom machine-learning based workflow controller, a validation of GSV as a viable curb ramp data source, and a detailed examination of why curb ramp detection is a hard problem along with steps forward.

Measuring Password Guessability for an Entire University
<div class="mw-collapsible-content">
<br> Despite considerable research on passwords, empirical studies of password strength have been limited by lack of access to plaintext passwords, small data sets, and password sets specifically collected for a research study or from low-value accounts. Properties of passwords used for high-value accounts thus remain poorly understood.


We fill this gap by studying the single-sign-on passwords used by over 25,000 faculty, staff, and students at a research university with a complex password policy. Key aspects of our contributions rest on our (indirect) access to plaintext passwords. We describe our data collection methodology, particularly the many precautions we took to minimize risks to users. We then analyze how guessable the collected passwords would be during an offline attack by subjecting them to a state-of-the-art password cracking algorithm. We discover significant correlations between a number of demographic and behavioral factors and password strength.
<br/>


We also compare the guessability and other characteristics of the passwords we analyzed to sets previously collected in controlled experiments or leaked from low-value accounts. We find more consistent similarities between the university passwords and passwords collected for research studies under similar composition policies than we do between the university passwords and subsets of passwords leaked from low-value accounts that happen to comply with the same policies.

Exploring the role of HCI as an agent of cultural change: from health as a medical condition to health as shared, social aspiration.
<div class="mw-collapsible-content">
<br>Abstract: What is the role of HCI in supporting a better normal for our health, creativity, quality of life - especially if we think about health outside a medical context. I have been thinking about the concept of “make better normal” and Ben Shneiderman has challenged me to ask isn’t that the role of design in general? And most of us would agree, so what’s different when we talk about health, not as a medical condition, but as a paradigm shift, where health is a shared and supported social aspiration? In such a discussion, HCI becomes an agent not necessarily for change, but for cultural shift - assuming we might agree on what proactive health looks like in practice - so we can design to support it. As part of this discussion i’ll offer in5 as a design model for proactive health and look forward to your feedback.
<br>
<br>
Also, we might consider how the role of HCI would change in this dynamic over time. Initially, proactive health design is likely design against the status quo. For example, if the status quo is sedentary knowledge work, and the research shows that more movement during the day is better for us cognitively, physiologically, socially, then what does HCI do to help support this transition individually and culturally? What is the role and perhaps responsibility of our collaborative work with, for instance, visualisation and big data? Likewise, what is the map of this territory for us? where are the important research questions? how would we know them? Do we ourselves need to evolve a new disciplinary expertise from nutrition to neurology for proactive health tech design? I have some thoughts/experiences in this space i’d like to share to hear your insights. Also, in particular, I would also like to present the related outcomes from a Dagstuhl Workshop that happened in June to consider Grand Challenges for Interactive Technology Design for Proactive Health, and to invite you to participate in and contribute to shaping these Challenges. This exchange, i hope, will act as both this invitation and a call to action - to say that if we see the opportunities to make a real and credible difference for proactive health, do we not need to find, fundamentally, ways to better support each others’ work to have effects at scale, to model a path for others to trust and to follow?

ASSETS 2014 Practice Talk: Design of and Subjective Response to On-body Input for People With Visual Impairments
<div class="mw-collapsible-content"> <br>
For users with visual impairments, who do not necessarily need the visual display of a mobile device, non-visual on-body interaction (e.g., Imaginary Interfaces) could provide accessible input in a mobile context. Such interaction provides the potential advantages of an always-available input surface, and increased tactile and proprioceptive feedback compared to a smooth touchscreen. To investigate preferences for and design of accessible on-body interaction, we conducted a study with 12 visually impaired participants. Participants evaluated five locations for on-body input and compared on-phone to on-hand interaction with one versus two hands. Our findings show that the least preferred areas were the face/neck and the forearm, while locations on the hands were considered to be more discreet and natural. The findings also suggest that participants may prioritize social acceptability over ease of use and physical comfort when assessing the feasibility of input at different locations of the body. Finally, tradeoffs were seen in preferences for touchscreen versus on-body input, with on-body input considered useful for contexts where one hand is busy (e.g., holding a cane or dog leash). We provide implications for the design of accessible on-body input.

Citizen Science at Scale: Human Computation for Science, Education, and Sustainability
<div class="mw-collapsible-content">
<br>Citizen science is gaining recognition as an innovative mode of scientific collaboration that engages the public in real-world research. Increased coordination and communication capacities attributed to technological advances have lead to dramatic growth in the scale, scope, and impact of public participation in science, while also enabling novel research that would not otherwise be feasible. In addition, citizen science is full interesting challenges for HCI, with notable needs and opportunities for innovation in such areas as sensors, DIY technologies, mobile applications, painless data entry, usability for "K through gray", STEM learning technologies, and data visualization and exploration tools.
<br>
<br>
This talk will introduce two projects focused on supporting large-scale participation in citizen science from a data-centric perspective. In the eBird "human-computer learning network", 40% annual growth in data submissions to one of the world's largest biodiversity data sets creates a challenge for data validation by a limited pool of experts. Our team has applied AI and machine learning to refine the system's dynamically-generated data entry interfaces, reducing the incidence of "false positives" for outlier records that require expert review. In addition, we have developed a method to estimate contributors' expertise based entirely on their data submissions, and examining time series of these expertise estimates also suggests a learning effect through ongoing participation. The expertise estimates are currently being incorporated into spatio-temporal models of bird migration to reduce noise introduced by the natural variability in diverse human observers.
<br>
<br>
The second project, recently funded by the NSF CyberSEES program, will develop proof-of-concept infrastructure to deliver biodiversity data from science classrooms across the US to researchers that need data for ongoing research. Through partnerships with several sustainability science projects and the Smithsonian BioCubes program, student-generated data will be integrated with data collected by professional scientists to support ecological studies monitoring the spread and impact of invasive species, the biogeographic and evolutionary effects of climate change, and community changes in species-rich but vulnerable coastal marine ecosystems. The UMD team will investigate the factors that enable and prevent participation by both data producers (learners) and data consumers (scientists), in order to inform the design and development of current and future cyberinfrastructure.

Computational Journalism: From Tools to Algorithmic Accountability
<div class="mw-collapsible-content">
<br> Abstract: Computational Journalism was initially conceived of as an application of computing technologies to enable journalism across information tasks such as information gathering, organization and sensemaking, storytelling, and dissemination. But computing and algorithms can also become the object of journalism. Algorithms adjudicate a large array of decisions in our lives: not just search engines and personalized online news systems, but educational evaluations, markets and political campaigns, and the management of social services like welfare and public safety. A new form of computational journalism that I call “Algorithmic Accountability Reporting” is emerging to apply the core journalistic functions of watchdogging and accountability reporting to algorithms. In this talk I will provide some perspective on the tool-oriented roots of computational journalism, and then discuss how algorithmic accountability reporting is emerging as a mechanism for elucidating and articulating the power structures, biases, and influences that computational artifacts play in society.
<br>

Bio: Nicholas Diakopoulos is an Assistant Professor at the University of Maryland College of Journalism. His research is in computational and data journalism with an emphasis on algorithmic accountability, narrative data visualization, and social computing in the news. He received his Ph.D. in Computer Science from the School of Interactive Computing at Georgia Tech where he co-founded the program in Computational Journalism. Before UMD he worked as a researcher at Columbia University, Rutgers University, and CUNY studying the intersections of information science, innovation, and journalism.

Top-Down and Bottom-Up:  Building Information Science for an Active Middle
<div class="mw-collapsible-content">
<br> Abstract: Our increasingly digital society has spurred interest in information science, with a belief that it can improve health, safety, the environment, education, economic growth and more.  However, capturing these benefits will require skilled information professionals who understand and create digital solutions that improve lives in a variety of fields.  Guided by its focus on information, technology and people, the iSchool at the University of Maryland is developing an innovative BS in Information Science (BSIS) that will address the demand for such professionals.  High-level frameworks lend structure to the disparate information science activities and disciplinary domains, but lack the detail necessary to guide research and educational programs.  At this session, we will co-design the emergent BSIS curriculum that prepares students for success in a wide variety of information science careers.

Tracking the Body in Healthcare
<div class="mw-collapsible-content">
<br> New gesture and movement tracking technologies are offering rich possibilities for our everyday computing experiences. More than simply intuitive and non-intrusive forms of interaction these technologies can provide ways to transform behavioral practices in particular contexts. Within these contexts, there are important challenges in how we take the opportunities provided by body/movement sensing systems and design them in ways that are attuned to the demands and circumstances of a particular setting. In this talk I will explore these issues in the context of the particular setting of healthcare. I will present prior work on a Kinect-based system that uses gesture and voice recognition capabilities to enable clinicians to interact with images during surgery without compromising sterility as well as new work on sensing a Parkinson's patient's movement ability for clinical decision-making and patient empowerment.

Privacy Management in the Digital Age
<div class="mw-collapsible-content">
While regularly used for interpersonal communication, relationship maintenance, and information sharing, newer communication technologies such as Facebook and Twitter have also created significant tension between individuals’ desire to maintain privacy and to be engaged participants in online communities. Problems arise due to the increasing diversity of users on these sites, a lack of privacy management knowledge and/or skills, and the often-changing privacy standards of the sites themselves. Rather than proactively engaging this complexity, many users employ reactive privacy management strategies—until something bad happens to me, I won’t worry about the information I’m sharing.
Understanding how people conceptualize privacy and how that conceptualization influences behavior is increasingly important in today’s networked world, as individuals—and information—are now connected in more ways than ever before. The affordances of social media distinguish them from other communication channels, both on- and offline, with content being easier to search and archive, while people and content are more highly linked within systems. Thus, the consequences of employing more reactive strategies are far-reaching, with potential impacts on personal relationships, financials, work, and beyond. In this talk, I’ll highlight some of my recent findings on this topic as well as overview my expected research trajectory for the next few years in this very active space.

From Digital Footprints to Social Insights
<div class="mw-collapsible-content">
The pervasiveness of cell phones, mobile applications and social media is generating vast amounts of information that can reveal a wide range of human behavior. From mobility patterns to social connections, these signals expose insights about how humans behave and interact with their environment. While a lot of work has focused on analyzing behaviors, relatively little effort has been dedicated to understanding ways in which such findings could be useful to decision makers in areas like smart cities or public health. In this talk I will discuss two projects: (1) AlertImpact, an agent-based framework that uses geo-referenced cell phone data to model the impact of the preventive actions implemented by the Mexican government during the H1N1 flu outbreak and (2) TweetLand, a method to automatically identify urban land uses and landmarks (point of interest) using tweeting patterns.

<div class="mw-collapsible mw-collapsed">
The goal of this session is to provide several students at various points in their academic programs
<div class="mw-collapsible-content">
, but especially new students, with a chance to talk about (1) their interests, (2) the projects to which they've contributed, and (3) those they'd like to do. Our hope is that this will allow new students to introduce themselves and convey their interests in a way that helps them find others with shared interests and form working relationships on projects with professors and other students. Students will have 5–8 minutes to introduce themselves and their interests, their previous and current projects, skills and expertise, and their future interests in HCI and the HCIL. Hopefully, this will help new students connect with professors and other students with whom they share interests and can work together on research projects. Following talks will be about 10 minutes for discussion with the presenting students (perhaps for asking them to join a project team).

Everybody’s internet? :Designing for mobile-centric internet users in the developing world
<div class="mw-collapsible-content">
Within 5 years, wireless broadband services will cover 85% of the world’s population,
and data-enabled mobile (cellular) devices will outnumber personal computers and
tablets. This talk, taken from a book in preparation, details the growing importance
of ‘mobile-centric internet use’ in the developing world, raising questions and
challenges for design.
A breathlessly optimistic narrative has proclaimed the mobile phone the device
which will finally close the ‘digital divide’, but the digital world does not run
exclusively on mobile handsets. To guide policy and technical investments in
socioeconomic development— I argue that it is better to reframe and view the
mobile handset as one piece of a person’s digital repertoire, which also might include
PCs, telecentres, TVs, tablets, and other devices.
In the talk and in the book I revisit some of my previous studies in three domains of
socioeconomic development: microenterprises and livelihoods, citizen journalism,
and secondary education. Across each, I celebrate the transformational potential of
the mobile phone. Yet, in each case, I use the “digital repertoires” lens to raise
concerns, identifying how the capacity to generate, produce, and curate information
may remain concentrated among those with better resources to secure digital tools,
and the skills and incentives to use them. The person with $30 basic data-enabled
phone and the person with a smartphone and a state-of-the-art $1000 desktop
computer both can connect to the internet; however, it is not the same internet.
Yet these persistent digital stratifications can be reduced if technologists,
researchers, practitioners, and policymakers work to ensure that constrained digital
repertoires enable not only coordination and consumption (which phones already do
well), but also contribution (which they do less well). From natural user interfaces to
language support to bandwidth pricing, there are concrete ways in which more
empathetic design and policy can help a greater proportion of the world’s
inhabitants be more productive with their ICTs.

<div class="mw-collapsible-content">
The Technology for Emerging Markets (TEM) group at Microsoft Research India seeks to address the needs and aspirations of people in the world's developing communities. Our research targets people who are just beginning to use computing technologies and services as well as those for whom access to computing still remains largely out of reach. Most of our work falls under the rubric of the relatively young field of Information and Communication Technology for Development (ICTD or ICT4D). By combining a variety of backgrounds and training, we are able to engage deeply with some of the complex problems associated with poverty and scarce resources. Our goal is to study, design, build, and evaluate technologies and systems that are useful for people living in underserved rural and urban communities around the world. In this talk, I will give an overview of some of the recent work in the group, focusing on projects that explore modalities and interactions specifically designed for the unique contexts and users we’re working with:<br>
1) VideoKheti: A prototype multimodal system to help low-literate farmers search for agricultural extension videos on smart phones.<br>
2) IVR Junction: A platform for building scalable and distributed voice forums for users with low-end phones.<br>
3) Massively Empowered Classrooms (MEC): A project to explore how innovations in MOOCs and blended learning can be applied to second-tier, large-scale engineering education in India.<br>

<div class="mw-collapsible mw-collapsed"> HCI and Networking - Taming the Internet One Bit at a Time
<div class="mw-collapsible-content">
Abstract:<br>
As we become more dependent on high speed Internet, we increasingly have to deal with making sure our devices are connected properly, that we're getting the speeds we need, and that we're making efficient use of our data. Yet often, Internet connections break or do not work as planned, causing us endless headaches. We also have to juggle constraints such as slow speeds, limited bandwidth, and high data costs depending on our location and use. My research focuses on helping users manage Internet connectivity in their homes, the workplace, and on the go, particularly under constraints of low resources and high costs. In this talk, I'll go over how I use HCI and networking to reach the goal of taming the Internet for everyday users and talk about future directions.

Cross-Device Frameworks for Collaborative Visualization


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.

Using these two frameworks, we are currently working on 1) development of advanced interaction models for large display environments based on proxemics: the spatial attributes of users such as position, orientation, and distance, and 2) easing the process of collaboration in analytical activities by designing smart ways to share information (for instance, using QR codes).

Two kids, one iPad


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?

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.

Bio: Jochen "Jeff" Rick designs innovative and effective applications for the newest technologies to research the potential of these technologies to support collaborative, social, and exploratory forms of learning. With an M.S. Electrical Engineering (1999, Georgia Tech) and a Ph.D. Computer Science (2007, Georgia Tech), he feels comfortable developing for emerging platforms. He developed CoWeb, the first wiki designed to support learning, well before Wikipedia existed. He developed DigiTile, a tabletop application for two children to collaboratively learn about fractions through constructing colorful mosaic tiles, before there was a commercial touch tabletop. As an experienced designer (two major server technologies, six applications for interactive tabletops, two applications for tablets, two applications for multiple devices, etc.), he seeks to realize the future of learning technologies. He is the lead developer on UMCP's Science Everywhere project.

Designing Social Technologies for Creativity and Discovery


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.

Bio: Kurt Luther is Assistant Professor of Computer Science at Virginia Tech, where he is also a member of the Center for Human-Computer Interaction and a faculty affiliate in Human Centered Design. His general research interests include social computing, crowdsourcing, and creativity support tools.

SWARM: Sensing Whether Affect Requires Mediation


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.

Bio: Michele A. Williams is a Human-Centered Computing PhD candidate at UMBC. She holds a B.S. in Computer Science from Bowie State University and a Masters of Software Engineering from Auburn University where she concentrated in human-computer interaction and her thesis consisted of a multimodal intelligent tutoring system.

IUI '15 Practice Talk


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


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.

Bio: Hyojoon Kim is a Ph.D. candidate in the School of Computer Science at the Georgia Institute of Technology under the supervision of Professor Nick Feamster. He is broadly interested in computer networks and systems, but currently focus more on network configuration analysis, network reliability enhancement, and building better abstractions for network management. He received his B.S. in Computer Science from University of Wisconsin - Madison and M.S. from Georgia Tech. In the past, he has worked as a research engineer at Future Systems, a major manufacturer of network & security solutions in South Korea, and did several internships at HP Labs-Palo Alto, CA, USA.

CHI Practice Talk: Understanding the role of thermography in energy auditing: current practices and the potential for automated solutions


Abstract: (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.

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


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.

CHI Practice Talk: Trajectory Bundling for Animated Transitions


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.

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


Abstract: (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.

Open Government Data and Civic Applications: What would successful collaboration look like?


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.

Building a Plane in Mid-air


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.

Bio: Heather Bradbury, Director of MICA’s Masters of Professional Studies programs in Information Visualization and the Business of Art and Design, comes to MICA with over 15 years of experience in the fields of creative and educational project development and strategic communication. Heather’s background and broad professional experience, including Communications Specialist at the Maryland State Department of Education, Office of the State Superintendent; IDEAS Grants Manager and Education Specialist at the Space Telescope Science Institute (Home of Hubble Space Telescope); and co-owner of Balance-the Salon, an award-winning hair salon and photo gallery, provides her with a unique perspective in business operations and management as well as communication through various mediums to tell stories.

Social Information Spaces: Designing for Smart(er) Societies


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.

Interface design for the Analysis and Data Mining of the large data coming out of the ALMA telescope


Abstract: 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.
