Brown Bag Lunch Schedule

The HCIL has an open semi-organized weekly "brown bag lunch (BBL)" on every Thursdays from 12:30-1:30pm in HCIL (2105 Hornbake, South Wing). The topics range from someone's work, current interest to the HCIL, a software demo/review, a study design, a proposed research topic, an introduction to a new person, etc. The BBL is the one hour a week where we all come together--thus, it’s a unique time for HCIL members with unique opportunities to help build collaborations, increase awareness of each other’s activities, and generally just have a bit of fun together with free food every week.

To sign up for a session, send an email to BBL student co-coordinator Arunesh Mathur (amathur@umd.edu) or Daniel Pauw (dpauw@umd.edu). In the email, briefly describe the topic and preferred dates.

To get notified about upcoming events, please subscribe one of these mailing lists.

We thank YAHOO for its sponsorship of the HCIL Brown Bag Lunches .

02/19/2015	Jeff Rick Developer and Researcher, ScienceKit project (link)	Expand 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.

	Meethu Malu PhD Student, Department of Computer Science (link)	Expand 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.
04/09/2015	Fan Du PhD Student, Department of Computer Science (link)	Expand 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.

09/25/2014	Kotaro Hara CS PhD Student: (link)	Expand UIST2014 Practice Talk: Tohme: Detecting Curb Ramps in Google Street View Using Crowdsourcing, Computer Vision, and Machine Learning 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.
10/02/2014	Michelle Mazurek Assistant Professor, Department of Computer Science (link)	Expand Measuring Password Guessability for an Entire University 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. 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.
10/09/2014 (room 2119)	m.c. schraefel Professor, University of Southampton (link)	Expand Exploring the role of HCI as an agent of cultural change: from health as a medical condition to health as shared, social aspiration. 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. 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?

10/16/2014	Uran Oh CS PhD Student	Expand ASSETS 2014 Practice Talk: Design of and Subjective Response to On-body Input for People With Visual Impairments 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.
10/23/2014	Andrea Wiggins Assistant Professor, iSchool (link)	Expand Citizen Science at Scale: Human Computation for Science, Education, and Sustainability 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. 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. 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.
10/30/2014	Nicholas Diakopoulos Assistant Professor, UMD College of Journalism (link)	Expand Computational Journalism: From Tools to Algorithmic Accountability 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. 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.

11/06/2014	Susan Winter Assistant Program Director, MIM	Expand Top-Down and Bottom-Up: Building Information Science for an Active Middle 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. Bio: Susan J. Winter, Ph.D. is Chair of the UG Committee, Director of Research Advancement, Assistant Director of the MIM Program and of CASCI at UMD’s iSchool. She has previously been a Science Advisor in the Directorate for Social Behavioral and Economic Sciences, Acting Deputy Director of the Office of Cyberinfrastructure and a Program Director at NSF supporting distributed, interdisciplinary scientific collaboration where she was responsible for programs funding research on virtual organizations as sociotechnical systems, cyber-enabled discovery and innovation, and cyberinfrastructure education, and enabling resources for building community and capacity for complex data-driven and computational science including high performance computers, large-scale databases, and advanced software tools. Her research on the impact of IT on the organization of work has appeared in top journals; she has extensive international managerial and consulting experience, and currently serves on the editorial boards of top Journals.

Jan 30	Helena Mentis New UMBC HCI faculty member bio	Expand Tracking the Body in Healthcare 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.

March 6	Megan Monroe PhD Student homepage	Expand The Talk Talk So you have to give a talk, now what? Well, it's probably too late to run, and nobody likes a hider, so your best bet is to just suck it up, and start prepping your talk. But how? What should you do first? What are you even trying to accomplish here? Prepping a talk is not only a daunting prospect, but it's really easy to get lost in the details and lose sight of the big picture. In this brown bag, I'll be laying out that big picture, and providing a step-by-step roadmap of how to get there. The goal is to give rookie talk-givers a better sense of direction as they navigate the shadowy abyss of prepping a talk. I'm also hoping that some of the more experienced talk-givers can chime in with some of their best tips and tricks for building a slammin' talk. Megan Monroe is a fifth year PhD student in the Computer Science Department who feels super awkward writing about herself in the third person. That being said, she has given a lot of talks, and is loosely presumed to proficient in this area.

March 27	Jessica Vitak Assistant Professor in iSchool HCIL faculty member bio	Expand Privacy Management in the Digital Age 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.

In this talk, Chris (and others) will lead a talk and discussion about GitHub. Generally, Chris will give an overview of GitHub and facilitate a discussion about why the HCIL might want to adopt GitHub in some way, perhaps by making an "Organization" entity under which projects can be created and students, faculty, and others in the HCIL can check in their code.
April 10	Vanessa Frias-Martinez Assistant Professor in iSchool bio	Expand From Digital Footprints to Social Insights 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.
April 17	Alex Pompe Senior Technical Advisor at IREX	Expand Bridging ICT4D lessons from the NGO sector towards academia (Slides) Abstract: ICT4D professionals in both the academic and NGO areas stand to benefit from greater collaboration, awareness, and transparency of experiences. However, often at conferences both groups are frustrated due to a lack of common understanding and misconceptions. This talk will present a number of case studies from IREX's ICT work in a variety of regions focused on providing open discussion and discourse so that lessons from all development practitioners can be lent towards improving processes on both sides of the table. The talk will also include discussion of internships and job skills in the ICT4D sector from an NGO employer's perspective. As a Senior Technical Advisor at IREX, Alex Pompe is a lead member of the Center for Collaborative Technology managing the NGO's ICT4D consulting portfolio. Clients come for a range of countries such as Sri Lanka, Malaysia, India, Nepal, Romania, Ukraine, Moldova, and Bhutan.

Th, Sept 19	HCIL/HCI Graduate Students facilitated by Michael Gubbels and Tak Yeon Lee	Talk/Discussion	Expand The goal of this session is to provide several students at various points in their academic programs , 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).
Wed, Sept 25	Jonathan Donner	External Speaker	Expand Everybody’s internet? :Designing for mobile-centric internet users in the developing world 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.

Th, Oct 3	Ed Cutrell	External Speaker	Expand Technology for Emerging Markets (TEM) group at Microsoft Research 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: 1) VideoKheti: A prototype multimodal system to help low-literate farmers search for agricultural extension videos on smart phones. 2) IVR Junction: A platform for building scalable and distributed voice forums for users with low-end phones. 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. 4) Maybe something else, depending on the interests of the audience Bio: Ed Cutrell manages the Technology for Emerging Markets (TEM) group at Microsoft Research India. Ed has been working in the field of human-computer interaction since 2000, studying everything from novel interaction techniques to interfaces for search and information retrieval. His current research focuses on Information and Communication Technologies for Development (ICT4D). The goal of this work is to understand how people in the world's poor and developing communities interact with information technologies and to invent new ways for technology to meet their needs and aspirations. He is trained in cognitive neuropsychology, with a PhD from the University of Oregon. http://research.microsoft.com/~cutrell http://research.microsoft.com/en-us/groups/tem/
Th, Oct 10	Marshini Chetty Assistant Professor in iSchool and HCIL faculty member http://marshini.net	Talk	Expand HCI and Networking - Taming the Internet One Bit at a Time Abstract: 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. Bio: Marshini Chetty is an Assistant Professor in the College of Information Studies at the University of Maryland specializing in human computer interaction and ubiquitous computing. Marshini's research focuses on making information about infrastructure technologies more readily available to everyday users to help them manage complex systems such as broadband networks.
