To block or not to block: Understanding the effects of programming language representation in high school computer science classrooms. Abstract: In the last few years, Chicago, New York City, and San Francisco have all announced major initiatives to bring computer science classes and computational thinking into every high school in their cities - with countless other smaller school districts following suit. Having made these commitments, attention now shifts towards how best to teach computer science to diverse populations of high school students who grew up in the age of smart phones, iPads, and Facebook. An increasingly popular strategy being employed is the use of graphical, block-based programming environments like Scratch, Blockly, and Alice. While these environments have been found to be effective at broadening participation with younger learners, open questions remain about their suitability in high school contexts. In this talk, I will present findings from a two-year classroom study looking at how the design of introductory programming environments affects learners' emerging understandings of computer science concepts and their perceptions of the field of computer science. I will also discuss the affordances of block-based programming environments relative to more conventional text-based alternatives.

From Independence to Interdependence: A Social Narrative of Assistive Technology Abstract: In the Assistive Technology and greater disabilities community, “independence” has been a core goal and frame for making progress toward equality. This dominant narrative is often interpreted to mean that disabled people can and should live independently without help from others, and that assistive devices exist to displace reliance on helpers. For example, a wearable device that gives a blind person turn-by-turn directions through an airport displaces a sighted human guide. However, my work with people with disabilities in the home, in the workplace, and in public spaces has demonstrated that collaboration is a significant tool and goal of people with disabilities in their everyday lives. Further, social setting and human-human interactions significantly impact whether and how assistive devices are used. In this talk, I will share and unpack stories from people with various abilities to argue that assistive technology design through the lens of “interdependence” provides a more honest, respectful, and empowering alternative for assistive technology design.

Gabriela: Addressing health inequities through human-centered design Talk 1 - Abstract: When we use empathy and human-centered approaches in developing health interventions, we have the capacity to affect social change. We can direct human-centered computing toward underserved populations. We can target marginalization, stigma, and inequity with human- centered methods. In this talk, I will share projects that have focused on addressing inequities within children’s behavioral health services, treatment for youth living with HIV, and opioid overdose prevention. I will present methodological approaches to designing for and with underserved populations, and show how to practice inclusion and equity in the design process. Based on the results of my projects, I will also outline design principles for health information technologies that do not sacrifice humanity for standardization. Finally, I will discuss the importance of broadening participation in computing, for more equitable research participation, methods, and output.
This talk discusses three main areas in this research: 1) How well does OSN data reflect real-world population data, 2) What are the patterns in response behavior to these events, and 3) How can low-quality information be filtered out from these data sources? I will present findings across these questions, showing social media data mirrors certain geographic populations, discussing event-detection algorithms, and outlining some current research in cross-platform information quality. I will then open discussion on future work in: OSN data for qualitative study, crisis informatics, and studies of population/platform differences in online information quality.
Bio: Dr. Cody Buntain is a postdoctoral research fellow at the University of Maryland’s Human-Computer Interaction Lab and is funded by the Intelligence Community Postdoctoral Fellowship.

Designing with Data: How machine learning is morphing human, product, and system design Abstract: The nature of product design has increased in scale, both inside corporations and in self-organized online communities (e.g., OpenIDEO, Local Motors). This is thanks to unprecedented amounts of digital design information made possible by globally distributed groups of thousands of people who collaborate together on design projects over the Internet. However, this increased scale and diversity comes with a price: 1) these groups generate more data than they can effectively use, 2) it becomes difficult to leverage their diverse expertise, and 3) involving non-experts meaningfully the design process, particularly for complex mechanical systems, requires rethinking how people interact with design tools and what kind of intelligent support we need to provide.

Exploratory visualization tools for health records research, and an exciting detour into infrastructural support for health records research at UMD Abstract: Important medical research is increasingly based on analysis of data collected during provision of routine care. Compared to clinical trials data, this "secondary use" data is not susceptible to randomized, prospective study protocols; it suffers from poor quality and extreme "missingness" for observational or retrospective methods; strict privacy and human subjects regulations limit its availability; processing it for analysis is complicated by the diversity of its sources, formats, and the plethora of language and coding systems in which it is recorded; and analyzing it generally requires advanced clinical training and methods for grappling with its extreme multi-variateness, sparsity, and unknown systemic biases. Despite these formidable challenges, this data is orders of magnitude cheaper and more prolific than clinical trial data. Researchers and analysts within medical provider institutions can have access to data for millions of patients essentially for free; while medical products companies, regulators, and payer institutions can affordably purchase data for hundreds of millions of patients. Further, although analysts' uses cases are diverse and their methods (e.g., advanced statistics or machine learning) often opaque as well as immature; they share many basic questions and tasks: they almost universally need to characterize their populations on various demographic and clinical dimensions; they generally need to choose study and comparator cohorts; they need to group patients by disease and treatment parameters; they need to evaluate the significance of untold co-morbidities and confounders; they need to explore and discover temporal patterns obscured by the volume and variability of the data. The advent of common data models and open-source software is just beginning to drastically streamline research workflows with this data. For analysts with access to data in OHDSI (ohdsi.org) format, for instance, many months of the standard observational study workflow can be skipped entirely. OHDSI's web-based cohort construction tools and it's open and growing R methods library allow researchers not only to define and execute their studies in hours or days rather than months, these researchers can now instantly and precisely share their code and aggregate results in a research network to be immediately replicated on dozens of other databases containing records for hundreds of millions of patients. What this means for my research is: 1) my visualization tools can be built to a single data model and can be tested with a wide variety of use cases and without requiring my subject matter expert collaborators to perform data collection and transformation just to work with me; and 2) my tools can be built with immediate integration into platforms they are already using, so, for instance, they can take advantage of these experimental visualization tools as they design their study and set parameters; they can feed those parameters into their statistical or machine learning algorithms; and they can then (continuing in the same platform) use these visualization tools to explore and evaluate results. What it also means for my research, for better or worse, is that my model for developing and evaluating visualization software and working with users and collaborators is very different from what HCI researchers are used to, and, since no one at UMD (as far as I know) is using OHDSI or anything like it, I have been spending more time explaining and evangelizing for my preferred research platform than for my research itself. At the Brown Bag I will talk about both; but depending on audience interest (some of our visualization researchers will be off at IEEE VIS this week), I may end up focusing more on the infrastructural issues.

Designing for User Agency and Participation Abstract: Digital technologies provide many opportunities to engage the interest and attention of users of all ages. A central question for the designers of these systems is what aspects of user interaction do they want to encourage and emphasize. In this talk, I present several research projects in which I designed digital systems to motivate user participation and collaboration. These projects include a digital living media system that engages child users though the dynamics of caring and responsibility and a Do-It-Yourself (DIY) open-source communication board for non-verbal users. For each project, I describe how I worked closely with various stakeholders including children, parents and teachers. I conclude with reflections on how to design digital system to support human agency and participation.

Teacher Noticing: Leveraging Technology to Explore Noticing and Noticing to Explore Technology Abstract: We introduce technology-mediated teacher noticing (TMTN): a vision for the design and use of technology-mediated tools that takes seriously the need for teachers to attend to, interpret, and respond to their students’ thinking. This vision is situated at the intersection of research on teacher noticing, and on technology to support student thinking. We synthesize that work to highlight specific ways that technology-mediated classroom tools can focus and stabilize teachers’ attention on valuable aspects of student thinking emphasized by current reform efforts. We then illustrate TMTN with classroom examples in which technology supported or obstructed teachers' attention to student thinking, and consider implications for research on technology in teacher practice, professional development, and the design of technological tools for K-12 classrooms.

Visualizing and Exploring Cliques and Cartel-Like Patterns in Citation Networks Abstract: With the growing emphasis on metrics such as citation count and h-index for research assessment, several reports of gaming and cartel-like formations for boosting citation statistics have emerged. However, such cartels are extremely difficult to detect. This paper presents a systematic approach to visualizing and computing clique and other anomalous patterns through ego-centric citation network analysis by drilling down into the details of individual researcher’s citations. After grouping the citations into three categories, namely, self- citations, co-author citations, and distant citations, we focus our analysis on the outliers with relatively high proportion of self- and co-author citations. By analyzing the complete co-authorship citation networks of these researchers one at a time along with all the co-authors and by merging these networks, we were able to isolate and visualize cliques and anomalous citation patterns that suggest plausible collusion. Our exploratory analysis was carried out using the citation data from Web of Science (now Clarivate Analytics) for all the highly cited researchers in Computer Science and Physics. I will also discuss some of the potential research opportunities in 'citation analytics'.

How do art & design accelerate research in science & engineering? Abstract: Leonardo is the classic example of fusion between art and science, as well as design and engineering. His artistic side amplified his perceptual abilities enabling him to make scientific breakthroughs about human anatomy, hydraulics, optics, and much more. Similarly, Pasteur’s training in lithography sensitized him to understand the chirality of molecules. Artistic skill enabling science is but one of four paths that I see. A second path is that the demands of art push science and engineering forward, as in the case of Karl Heinz needing to create the MP3 algorithms for compressing music. A third path is that the playful, exploratory, iterative, and divergent methods of art & design free up scientists and engineers to expand the range of their thinking. A fourth path is that products of art & design, such as paintings, sculpture, music, or film can directly inspire scientists and engineers. This talk will present further examples and call for closer connections across these disciplines.

A New Genre of Human Computer-Interaction and Interfaces for 3D Creative Design and Fabrication Abstract: The convergence of many factors such as low cost sensors, electronics, computing, machines, and more recently machine learning have created the potential for changing the way users engage with the physical world. This talk will explore and demonstrate how we can create new geometric interfaces and interactions that leverage our knowledge of the physical world for 3D design and fabrication. These new methods and tools enable users to personalize designs using new machines. In the first part of the talk we will explore how any consumer with little knowledge of computers can repurpose everyday objects and or shapes and quickly customize them to foldable constructions. Such constructions are then used to create robots in the physical world. In the second part we will see how new interactive workflows using a smart phone and tablets with pen-and-touch interfaces can be used for collaborative 3D design ideation. As a result of low thresholds and simple user interactions with lower cognitive loads, users are shown to explore multiple creative pathways. In the last part of the talk we will examine how a new deep learning technique, “SurfNET”, transforms a single image into 3D shapes and even hallucinate shapes that it has not seen. We envision a future with personalized manufacturing interfaces that lower the barrier for many to participate in the design and fabrication processes.

Taking a Teen-Centric Approach to adolescent Online Safety Abstract: Most online safety tools (i.e., “parental controls”) are designed to meet the needs of parents and young children, ignoring the complex developmental needs of adolescents (ages 13-17) as they transition into adulthood. This makes sense; it is easier to design sociotechnical solutions that monitor and restrict undesirable behavior than it is to build systems that help adolescents youth how to self-regulate their own actions. Similarly, it is also more clear cut to create laws, such as the Childrens’ Online Privacy Protection Act (COPPA), that protect younger children (ages 13 and under), that together, either result in teens being treated like children or leaving teens to virtually fend for themselves. In my talk, I discuss the status quo of technical solutions for adolescent online safety and propose a paradigm shift towards more teen-centric approaches for keeping adolescents safe online, which includes empowering teens to self-regulate their online behaviors to more effectively manage the risks (e.g., information breaches, cyberbullying, sexual solicitations, and exposure to explicit content) they may encounter online.

Human-Centered Principles and Methods for Designing Robotic Technologies Abstract: The increasing emergence of robotic technologies that serve as automated tools, assistants, and collaborators promises tremendous benefits in everyday settings from the home to manufacturing facilities. While these technologies promise interactions that can be highly complex and beneficial, their successful integration into the human environment ultimately requires these interactions to also be natural and intuitive. To achieve complex but intuitive interactions, designers and developers must simultaneously understand and address human and computational challenges. In this talk, I will present my group’s work on building human-centered guidelines, methods, and tools to address these challenges in order to facilitate the design of robotic technologies that are more effective, intuitive, acceptable, and even enjoyable through successful integration into the human environment. The first part of the talk will review a series of projects that will demonstrate how the marrying of knowledge about people and computational methods through a systematic design process can enable effective user interactions with social, assistive, and telepresence robots. The second part of the talk will cover ongoing work that provides designers and developers with tools to apply these guidelines to the development of real-world robotic technologies and that utilizes partnerships with domain experts and end users to ensure the successful integration of these technologies into everyday settings. The talk will conclude with a discussion of high-level design guidelines that can be drawn from this body of work.

Designing for Diversity: HCI and the Support of Scientific Research Abstract: Understanding user needs and designing new technologies to meet those needs has long been a focus of HCI research. HCI has been embedded within a sociotechnical systems approach often considering user needs within a work context where an employing organization designs the work, chooses the technologies, and hires and trains the employees. This organizational “container” has been eroding, which raises interesting questions about the relationships among people, innovative technologies, work, and the role of HCI in this new hyper-diverse environment.

Using Business Intelligence and Machine Learning in financial decision making in Cybersecurity sector Abstract: Cybersecurity is a complex and multifaceted challenge that is continuously growing in importance. It is a concern that not only affects banks and government agencies, as it constantly revealed through the media, but its implications expand beyond. It comes as no surprise that Wall Street would push efforts to cash in on the opportunity that is cybersecurity. In fact, cybercrime is fueling a worldwide cybersecurity market which is expected to grow from $75 billion presently to $170 billion by 2020. Hundreds of billions of dollars are being spent by consumers, businesses, governments, and the rest of the world to secure our ever-changing catalog of technology including, PCs, personal and corporate networks, the Internet of Things (IoT), and mobile devices. Despite a tumultuous stock market and poor venture capital returns, cybersecurity companies are raising large rounds of financing from investors. Due to the nascent nature of this field, the highly data-driven investment methodologies of old are not effective in guiding investment decisions. Investors complain that these methods are not agile and fall short when keeping up with current trends in the cybersecurity market. Our research utilizes principles of business intelligence and the latest research in hacker cognitive psychology to present a comprehensive, informative and easily digestible indicator for investors that is agile and self-optimizing. We present a model that considers blogosphere sentiment, relevant news, trend data, and real-time cyber-attack tools, techniques, and procedures to produce an investment indicator that will assist investors in their decision making. |

Gaming the System: How Useful are Game-based Approaches for Crowdsourcing Content? Abstract: Crowdsourcing has become a major way of getting work done through an online community. In addition to employing volunteers or paid human experts, computer games are a possible means to attract participants for crowdsourcing projects. Such games are seen as a promising approach to crowdsourcing because they capitalize on people's desire for entertainment. In other words, they make crowdsourcing fun and engaging, fostering participation in the process. This talk will introduce game-based approaches for crowdsourcing. The talk will illustrate these ideas in a specific context of crowdsourcing content, and in particular, mobile media. By blending games with crowdsourcing of mobile media, such applications provide entertainment and content is created as a result of gameplay. Nevertheless, there are challenges associated with game-based approaches for crowdsourcing since they have to meet the twin goals of entertaining users and producing quality output. Through various studies that will be presented, issues in creating these games as well as design lessons are discussed.

Abstract: The Scaled Agile Framework (SAFe) has provided one of the most accepted and widely used methods with which to scale agility within an organization. It also inherently calls upon the delivery of value to the customer. While value is typically encapsulated within the value stream, through areas such as vision and UX, one word that cannot be found anywhere within the framework is "culture". This talk explores how consideration of culture and the target user(s) can dramatically shift the direction of a project, value stream or business. It also covers how this influences the vision and UX design within a portfolio. It will cover the cost of refactoring legacy code that did not consider target demographics when initially conceived, as well as some of the UX Research methods, such as ethnography, that can be used to build cultural consideration within your business model. It will help people focus on a larger picture than just a team, project, program or portfolio approach to the end user... that end users themselves function as a system of systems that needs to be considered. The talk is primarily aimed at intermediate practitioners: ScrumMasters/Developers/UX Content Strategists/Product Owners/CEOs/Biz Dev/UX Researchers/UX Designers/SAFe Practitioners This session will be of interest to those with intermediate experience who work in UX, Agile, Business or Portfolio Vision/Management and who have an interest in how culture can be considered in SAFe and other Scaled Agile approaches. |

Anthony Pellicone The Game of Performing Play: Understanding Streaming as Cultural Production Abstract : Live streaming has become pervasive in digital game culture. Previous work has focused largely on technological considerations in streaming platforms. However, little is known about how streamers enter the practice, gain skills, and operate as content producers. We present a qualitative study of an online forum dedicated to streaming. By observing the conversations between veterans and newcomers to the practice, we develop an understanding of how streamers must tie together technological, social, and gameplay-based skills to craft an appealing performance of play. We find that a key skill in streaming is the development of a unique attitude and persona as a gamer, which permeates into every element of a streamer’s performance. As individual identity becomes important in streaming practice, design considerations for platform features such as community moderation and stream metrics may help improve equitable participation in this increasingly important aspect of game culture. Bio: Anthony is in his fifth year of the Information Studies PhD program at the University of Maryland, and he will be defending his dissertation in May. Generally, he is interested in the ways that people learn, socialize, and play in online spaces dedicated to games. His previous work has centered on digital gameplay as an experience that is connected across multiple platforms and communities, and the culture of play in these environments. Currently he is researching both informal science learning in Alternate Reality Games, as well as live-streaming video games as an act of performance and cultural production.
Where is the Digital Divide? A Survey of Security, Privacy, and Socioeconomics Abstract: The behavior of the least-secure user can influence security and privacy outcomes for everyone else. Thus, it is important to understand the factors that influence the security and privacy of a broad variety of people. Prior work has suggested that users with differing socioeconomic status (SES) may behave differently; however, no research has examined how SES, advice sources, and resources relate to the security and privacy incidents users report. To address this question, we analyze a 3,000 respondent, census-representative telephone survey. We find that, contrary to prior assumptions, people with lower educational attainment report equal or fewer incidents as more educated people, and that users’ experiences are significantly correlated with their advice sources, regardless of SES or resources. Bio: Elissa Redmiles is a Ph.D. student at the University of Maryland in Computer Science. Her research focuses on understanding and measuring users' security behavior and developing security education interventions for at-risk users. She is the recipient of an NSF Graduate Research Fellowship and a Facebook Fellowship. Prior to pursuing her Ph.D., Elissa held Marketing Management and Software Engineering roles at IBM and was a Data Science for Social Good Fellow at the University of Chicago.
Gains from Participatory Design Team Membership as Perceived by Child Alumni and their Parents Abstract: The direct gains children perceive from their membership on Participatory Design (PD) teams are seldom the focus of research studies. Yet, how HCI practitioners choose to include children in PD methods may influence the value participants see in their participation, and thereafter the outcomes of PD processes. To understand what gains former child members of a PD team perceive from their participation we conducted a two-part study. In Study 1 we surveyed and interviewed child alumni of a PD team to determine gains that are perceived first-hand. In Study 2 we obtained a secondary perspective by surveying and interviewing parents of alumni. We report on the perceived gains to former participants that were identified and described in these two studies—including collaboration, communication, design process knowledge, and confidence. We reflect on our findings through discussions of the continued applicability of gains, new opportunities, and implications for PD practitioners and methods. Bio: Brenna is a PhD candidate in Information Studies at the University of Maryland’s Human-Computer Interaction Lab (HCIL). Brenna’s thesis investigates participant perspectives on their membership in an intergenerational Participatory Design team, with a focus on how participants view the ethics of their participation and perceive gains from participation. Brenna is also the Research Coordinator for Kidsteam: A co-design team that works with children to design technologies that support children’s learning and play. Through this work she has been a part of the design of many amazing children’s technologies with researchers throughout the university as well as numerous industry (e.g., Pearson International, Nickelodeon) and government (e.g., U.S. National Park Service, the Office of Science, Technology and Policy at the White House) organizations. Brenna has a M.S. in Human-Computer Interaction from the University of Maryland and a B.A. in Telecommunication- Digital Media, Art, and Technology from Michigan State University.

Majeed Kazemitabaar MakerWear: A Tangible Approach to Interactive Wearable Creation for Children Abstract: Wearable construction toolkits have shown promise in broadening participation in computing and empowering users to create personally meaningful computational designs. However, these kits present a high barrier of entry for some users, particularly young children (K-6). In this paper, we introduce MakerWear, a new wearable construction kit for children that uses a tangible, modular approach to wearable creation. We describe our participatory design process, the iterative development of MakerWear, and results from single- and multi-session workshops with 32 children (ages 5-12; M=8.3 years). Our findings reveal how children engage in wearable design, what they make (and want to make), and what challenges they face. As a secondary analysis, we also explore age-related differences. Bio: Majeed is Masters Student in the Computer Science department, working with Jon Froehlich in the HackerSpace. He co-designs, builds and evaluates technologies for children.
Exploring Novice Approaches to Smartphone-based Thermographic Energy Auditing: A Field Study Abstract: The recent integration of thermal cameras with commodity smartphones presents an opportunity to engage the public in evaluating energy-efficiency issues in the built environment. However, it is unclear how novice users, without professional experience or training, approach thermographic energy auditing activities. In this paper, we recruited 10 participants for a four-week field study of end-user behavior exploring novice approaches to semi-structured thermographic energy auditing tasks. We analyze thermographic imagery captured by participants as well as weekly surveys and post-study debrief interviews. Our findings suggest that while novice users perceived thermal cameras as useful in identifying energy-efficiency issues in buildings, they struggled with interpretation and confidence. We characterize how novices perform thermographic-based energy auditing, synthesize key challenges, and discuss implications for design.

Network Visualization and Immersive Analytics Abstract: In this talk I will give an overview of on-going and recent research activities in the Monash Adaptive Visualisation Lab (MArVL). We currently have two significant research initiatives. The first is Network Visualisation, an area we have exploring for many years, with a focus on developing techniques to produce high-quality diagrams using constraint-based optimisation and alternative, scalable approaches to visualise large graphs. Our second research thrust in recent years has been Immersive Analytics: developing a new research area for the visualisation community that seeks to investigate the use of emerging display and interaction technologies and techniques for visualisation visual analytics. We believe these new technologies represent the potential for a paradigm shift in the utility and ubiquity of visual thinking.

Contextual Design, Cool Concepts, and Women in Tech Project Abstract: Karen has recently joined University of Maryland as a Research Scientist and will provide a brief overview of her work in user-centered design techniques and innovation as well as her new work understanding and creating intervention methods to help technology companies retain women. Karen will share the new techniques described in her upcoming book Contextual Design V2: Design for life. Because of the revolution in how technology is now integrated into life with smartphones and tablets, designers and researchers must consider new ways of collecting and using user data. The Cool Project helped define the key aspects we must now consider; these led to changes in the Contextual Design Method. Karen will also share the focus of her research on women in technology at the iSchool . Currently through collaborating with many in the industry The Women in Tech Project presents a framework for what keeps women satisfied and successful. They have also developed a measure which is being honed. More research will be occurring as well as the creation of intervention games and techniques.
Karen is a member of the CHI Academy (awarded to significant contributors in the Computer Human Interaction Association) and in 2010 received CHI’s first Life Time Award for Practice for her impact on the field. She holds a doctorate in applied psychology from the University of Toronto.

How I Learned to be Secure: a Census-Representative Survey of Security Advice Sources and Behavior Abstract: Few users have a single, authoritative, source from whom they can request digital-security advice. Rather, digital- security skills are often learned haphazardly, as users filter through an overwhelming quantity of security advice. By understanding the factors that contribute to users' advice sources, beliefs, and security behaviors, we can help to pare down the quantity and improve the quality of advice provided to users, streamlining the process of learning key behaviors. In this work we rigorously investigated how users' security beliefs, knowledge, and demographics correlate with their sources of security advice, and how all these factors influence security behaviors. Using a carefully pre-tested, U.S.-census-representative survey of 526 users, we present an overview of the prevalence of respondents' advice sources, reasons for accepting and rejecting advice from those sources, and the impact of these sources and demographic factors on security behavior. We find evidence of a "digital divide" in security: the advice sources of users with higher skill levels and socioeconomic status dier from those with fewer resources. This digital security divide may add to the vulnerability of already disadvantaged users. We conclude with recommendations for combating the digital divide and improving the efficacy of digital-security advice.

Using Human Centered Design to Make Informed Consent Actually Inform Abstract: Mobile technologies have the potential to revolutionize both the way in which individuals monitor their health as well as the way researchers are able to collect frequent, yet sparse data on participants in clinical studies. In order for data from these devices to have maximal impact in a research setting however, the development of systems to collect, manage, and broadly share these data is essential. Possibly more important are the social constructs on which these systems need to be built to allow maximal utility to come from these data while minimizing adverse impact on individual participants. More specifically, the union of these systems and constructs must be an ecosystem build upon trust. We will present one such ecosystem focused on putting the participant at the center of the data collection: specifically by acknowledging possible risks to both individual participants as well as sub-populations of participants, providing opt-in settings for broad data sharing, and the development of an open research ecosystem built upon a social contract between researchers and research participants. A case study of one such mHealth study, leveraging Apple’s ResearchKit framework, will be presented and discussed.

EventAction: Visual Analytics for Temporal Event Sequence Recommendation Abstract: Recommender systems are being widely used to assist people in making decisions, for example, recommending films to watch or books to buy. Despite its ubiquity, the problem of presenting the recommendations of temporal event sequences has not been studied. We propose EventAction, which to our knowledge, is the first attempt at a prescriptive analytics interface designed to present and explain recommendations of temporal event sequences. EventAction provides a visual analytics approach to (1) identify similar records, (2) explore potential outcomes, (3) review recommended temporal event sequences that might help achieve the users' goals, and (4) interactively assist users as they define a personalized action plan associated with a probability of success. Following the design study framework, we designed and deployed EventAction in the context of student advising and reported on the evaluation with a student review manager and three graduate students. http://hcil.umd.edu/eventaction

Exploring dimensions of 'place' Abstract: Place is one of the foundational concepts on which the field of Geographical Sciences has been built. Traditionally, geographic information science research into place has been approached from a spatial perspective. While space is an integral feature of place, it represents only a single dimension (or a combination of three dimensions to be exact), in the complex, multidimensional concept that is place. With the increased availability of large, user-generated datasets, it has becoming increasingly apparent that the value of 'big data' lies not necessarily in its size, but in its heterogeneity. In my research, I exploit this heterogeneity to build computational, data-driven models of human behavior, taking a multi-dimensional approach to investigating place and the activities people carry out at those places. In this talk I introduce the concept of Semantic Signatures built from spatial, temporal and thematic dimensions extracted from user-contributed, and authoritative datasets. I show how these signatures can enhance existing geolocation methods, form the foundation of place-similarity models and contribute to visualizing the platial pulse of a city.

Better Matching Markets via Optimization Abstract: The exchange of indivisible goods without money addresses a variety of constrained economic settings where a medium of exchange—such as money—is considered inappropriate. Participants are either matched directly with another participant or, in more complex domains, in barter cycles and chains with other participants before exchanging their endowed goods. We show that techniques from computer science and operations research, combined with the recent availability of massive data and inexpensive computing, can guide the design of such matching markets and enable the markets by running them in the real world. A key application domain for our work is kidney exchange, an organized market where patients with end-stage renal failure swap willing but incompatible donors. We present new models that address three fundamental dimensions of kidney exchange: (i) uncertainty over the existence of possible trades, (ii) balancing efficiency and fairness, and (iii) inherent dynamism. For each dimension, we design scalable branch-and-price-based integer programming market clearing methods. Next, we combine these dimensions, along with high-level human-provided guidance, into a unified framework for learning to match in a general dynamic setting. This framework, which we coin FutureMatch, takes as input a high-level objective (e.g., “maximize graft survival of transplants over time”) decided on by experts, then automatically learns based on data how to make this objective concrete and learns the “means” to accomplish this goal—a task that, in our experience, humans handle poorly.

Teaching JavaScript as Social Justice: Interrogating Culture, Bias and Equity in an Introductory Programming Course Abstract: When learning skills like computer programming, students need to develop an understanding of issues of culture, bias and equity at the same time that they learn the technical elements. As information professionals they will need to understand and navigate these issues. This presentation describes a course that integrates both social justice and technical elements, instead of separating them into different courses as is typical practice. I will describe the approach and structure and reflect on the experience and student feedback. I will invite all of us to discuss the creative tension in teaching both technical and ethical skills, and how we can embed these across the curriculum.
Before joining academia, Dr. Kules spent 20 years designing and implementing information systems for a variety of applications, including wireless telephony, customer service, banking, and a multimedia web sites. He earned his Ph.D. in Computer Science at the University of Maryland in 2006.

Usability of Three-dimensional Virtual Learning Environments: An Exploratory Study of the Think Aloud Approach Abstract: A recent review examining 10 years of research between 1999 and 2009 and focusing on the application of virtual reality technology for educational purposes, has found that the majority of interest from the research community has centered on the learning outcomes of such applications (Mikropoulos & Natsis, 2011). Out of the 53 studies reviewed by Mikropoulos & Natsis, 50 have examined the learning outcomes of such environments. While the findings of this review have revealed that learning outcomes were overwhelmingly positive for such environments, the review has also identified other topics of great interest and importance to such applications that have received very little attention from the research community. One specific topic that has not received adequate attention from researchers examining 3D virtual learning environments is usability. This is of great concern as usability has been shown to influence the learning experiences of users of 3D virtual learning environments, which in turn affects their learning outcomes (Dede, Salzman, Loftin, & Sprague, 1999; Lee, Wong, & Fung, 2010; Merchant et al., 2012).

All the Data Fit to Print: Newsroom Tools for Generating Personalized, Contextually-Relevant Visualizations (Campus Visualizations Partnership lecture) Abstract Visualizations can enhance news article content by presenting complex facts clearly and providing contextually-relevant visualizations. By using novel natural language and text mining approaches, our systems define "queries" that encode the article's topic (e.g., "unemployment in CA in March," "global average temperatures in 2012") and the comparisons that are made in the article's text (e.g., differences between states or over time) to guide the visualization generation. Compelling visualizations are relevant and 'interesting'-concepts that are very hard measure, but we address these challenges in the Contextifier, NewsViews, and PersaLog systems, which are meant to help journalists tell their stories more effectively (joint work with Brent Hecht, Jessica Hullman, Tong Gao, Carolyn Gearig, Josh Ford, and Nick Diakopoulos).

Community-based Data Validation in Citizen Science Abstract: Technology-supported citizen science has created huge volumes of data with increasing potential to facilitate scientific progress. However, verifying data quality is still a substantial hurdle due to the intended applications of data and limitations of existing data quality mechanisms. The talk discusses results from a paper that received an "Honorable Mention" at CSCW 2016 which investigated community-based data validation practices in an online community where people record what they see in the nature. We also examined the characteristics of records of wildlife species observations that affected the outcomes of collaborative data quality management. The findings describe the processes that both relied upon and added to information provenance through information stewardship behaviors, which led to improvements in indicators of data quality. The likelihood of community-based validation interactions were predicted by several factors, including the types of organisms observed and whether the data were submitted from a mobile device. Unexpected and counter-intuitive results reflect the realities of the material world in which mobile apps are deployed, and suggest implications for design and practice. The talk concludes with discussion of the evolution of recent developments in Federal policies related to crowdsourcing and citizen science.

Kotaro: The Design of Assistive Location-based Technologies for People with Ambulatory Disabilities: A Formative Study Abstract (Kotaro): In this paper, we investigate how people with mobility impairments assess and evaluate accessibility in the built environment and the role of current and emerging locationbased technologies therein. We conducted a three-part formative study with 20 mobility impaired participants: a semi-structured interview (Part 1), a participatory design activity (Part 2), and a design probe activity (Part 3). Part 2 and 3 actively engaged our participants in exploring and designing the future of what we call assistive locationbased technologies (ALTs)—location-based technologies that specifically incorporate accessibility features to support navigating, searching, and exploring the physical world. Our Part 1 findings highlight how existing mapping tools provide accessibility benefits—even though often not explicitly designed for such uses. Findings in Part 2 and 3 help identify and uncover useful features of future ALTs. In particular, we synthesize 10 key features and 6 key data qualities. We conclude with ALT design recommendations.
As a first step, we conducted 25 semi-structured interviews of a demographically broad pool of users. These interviews resulted in several interesting findings: (1) participants evaluated digital-security advice based on the trustworthiness of the advice source, but evaluated physical-security advice based on their intuitive assessment of the advice content; (2) negative-security events portrayed in well-crafted fictional narratives with relatable characters (such as those shown in TV or movies) may be effective teaching tools for both digital- and physical-security behaviors; and (3) participants rejected advice for many reasons, including finding that the advice contains too much marketing material or threatens their privacy.

How New Technologies Can Enhance Learner Autonomy Abstract: Find out more about the new technology-based approaches for supporting education from the perspective of learner autonomy. The University of Edinburgh and the British Open University have made extensive use of Massive Open Online Courses (MOOCs), including innovative applications of MOOCs to domains such as real-time political situations and citizen science. While to date, MOOCs and shared virtual environments have augmented rather than displaced more mature modes of e-learning, in the future, individual and distributed groups of learners will be able to become much more autonomous as they take advantage of new developments in data science.

or on a highly parallel infrastructure performing aggregations on the
fly. In my talk, I will explain why we need more flexible solutions and

Measuring Password Guessability for an Entire University
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. |

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. |

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. |

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. |

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.

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). |

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.

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: |
