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 (email@example.com) or Daniel Pauw (firstname.lastname@example.org). In the email, briefly describe the topic and preferred dates.

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.

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:
