Title:Embodied Computation for Social Learning: Findings from Field Research on Planning Support Systems
Abstract:After many years of discussion and research, professional urban planners are adopting a new class of digital planning support systems (PSS). Based on geographic information systems (GIS) software, these PSS allow stakeholders to create and compare development scenarios in real time at public workshops.
Through a mixed-methods research design, this study investigates the role of these new technologies in planning workshops in Boston, Kansas City, and Austin. The findings indicate high levels of social learning, broadly confirming the collaborative planning theory literature. Participants at planning workshops that incorporated embodied computing interaction designs reported higher levels of two forms of learning drawn from Argyris and Schön?s theory of organizational learning: single and double loop learning. Both were measured through a participant survey. Single loop learning is measured as reported learning. Double loop learning, characterized by deliberation about goals and values, is measured with a novel summative scale. These workshops utilized PSS to contribute indicators to the discussion through the use of paper maps for input and human operators for output. A regression analysis reveals that the PSS contributed to learning by encouraging imagination, engagement, and alignment. Participants' perceived identities as planners, personality characteristics, and frequency of meeting attendance were also related to the learning outcomes. However, less learning was observed at workshops with many detailed maps and limited time for discussion, and exercises lacking PSS feedback.
The development of PSS infrastructure and trends in the field will be briefly discussed.

Title:Sensemaking of Educational Data through Visualization and Machine Learning
Abstract:As instruction has moved online the amount of data we are able to collect about student interactions with learning resources has grown enormously. Every web page read, link followed, video streamed, and discussion message posted can be captured, aggregated, and analysed. In this talk I will share how information visualization and machine learning techniques can help us capitalize on this information. In particular, I will describe methods I have used to enable instructors to see the effects of their pedagogy, help students navigate through content faster and with more accuracy, connect predictive models to instructional design, and support educational researchers who are tying evidence to theory.

Title:Design Thinking Tools for the Individual, Group and Community
Abstract:Software tools serve a critical role in modern design thinking, from collecting inspirational materials on the Web to implementing the selected prototype. Despite many advances in recent years, existing tools still struggle to address the needs of users engaged in design thinking. For example, a tenet of design thinking is to generate multiple alternatives, yet the interface representations used in existing design tools do not effectively support this behavior.
In this talk, I will describe the inspiration for and the design and evaluation of several recent research projects that address problems and opportunities relevant to design thinking for the individual, group and community. The contributions of these projects include (i) the use of interactive spatial maps to organize design alternatives, enabling users to project meaning onto their exploration; (ii) an interactive visualization of design process that enables the user to capture and extract lessons and patterns from prior design activity; (iii) an on-demand method for generating structured feedback on visual designs using a crowd of non-experts; and (iv) an interface to aid design thinking in distributed user interface design discussions. The talk will include critical reflections on these projects and conclude with pathways for future work.
Bio:Brian Bailey is an Associate Professor in the Department of Computer Science at the University of Illinois, where he has been on the faculty since 2002.

Title:Supporting Creativity with Social Computing
Abstract:Social computing systems can catalyze and amplify creativity by connecting people from around the world and providing them with the tools to share ideas, coordinate efforts, and disseminate their creative products. Yet, we have only begun to tap into the creative potential of social computing, to understand its strengths and limitations, and to design technologies to promote its success. In this talk, I describe two significant challenges to creative social computing -- coordination and expertise -- and present one project/technology addressing each challenge.
In the first half, I will discuss the challenges of coordinating creative projects online, focusing on the example of collaborative animation projects called "collabs" on websites like Newgrounds.com. I will present Pipeline, a software tool I developed based on theories of distributed cognition and shared leadership, and report on an evaluation of Pipeline's effectiveness with a case study of a 30-member artistic collaboration called Holiday Flood.
In the second half, I will discuss the expertise challenges of using novice crowd workers to augment creativity in domains that require specialized knowledge, such as visual design. I will present CrowdCrit, a system I developed which uses a learning technique called scaffolding to help novice crowds on Amazon Mechanical Turk generate high-quality design critiques. I will share findings from a poster design contest co-hosted with a Pittsburgh music festival in which 14 participants received crowd critiques between iterations.

Title:Psychological Effects and Social Media Affordances: From Emotional Contagion at Scale to Virtual Hugs in Surgery
Abstract:How can social media play a role in our psychological health? Much has been written about how various Internet activities are associated with depression, narcissism, or even addiction. Given the startling ubiquity of social media in many aspects of everyday life in our society, we take a closer look at how some affordances of social media can influence our emotional and mental state in a series of experiments. I’ll talk about several new studies, including how Facebook can be self-affirming, how emotions can spread in a large-scale network experiment and how texting can alter our perceptions of pain, including reducing the amount of narcotics required during surgery. In contrast to studies that conclude that social media depresses us or makes us more narcissistic, I’ll draw conclusions about some of the psychological mechanisms that can allow social media to activate psycho- social resources in our day-to-day lives.
Bio:Jeff Hancock is an Associate Professor in the Departments of Communication and Information Science at Cornell University, where he is also co-Chair of Information Science and co-Director of Cognitive Science.

Title:The Other Side of Haptics: Movement as an Interaction Design Element
Abstract:Haptics as a research field concerns both the study of the touch senses and the development of technologies to display information to those senses. With respect to the development of hardware, the haptics community has hitherto focused on questions such as how to render the shape and texture of virtual objects and how to quantify the amount of information that can be transmitted to the human haptic senses. But such an approach is only one side of the haptic story because while it speaks to what we feel, it pays little attention to how we touch.
Our ability to pick up information through our haptic senses is closely related to how we move – we reach out to stroke the fur of a cat or we plunge our hand into water to see if it is warm or cold. In other words, the movements we perform are important because they determine what we can discover.
In this talk I will argue that such hand movements, and indeed the movement of the whole body connected to the hand, are the key to designing effective haptic interactions, whether in terms of developing new hardware or designing applications that use the touch senses. Drawing upon my prior work, I will demonstrate how movement can become a modality for interaction in its own right and will introduce the practical tools and the theoretical framework I have developed to enable the use of movement as an interaction design element.
Bio:Professor O'Modhrain has worked as a researcher and faculty member, both here and abroad, at the prestigious MIT Media Lab, Media Lab Europe, and at the Sonic Arts Research Center at Queen's University of Belfast. She has also worked for BBC Radio as an audio engineer and program producer. Her research focus is on haptics-touch and gesture-and its relationship to music performance and on the development of new interfaces for technology-enhanced instruments that extend the boundaries of musical expression. Also impressive is her combination of experience in many areas related to audio, psychoacoustics, computer music, cognition, and gestural control of music. She is internationally known and respected in her field, as evidenced by her record of scholarly accomplishment in well-regarded journals and as a frequent speaker at international conferences.

Title:Managing What’s on My Profile: Understanding Boundary Control on Facebook Through Temporal and Relational Lens
Abstract:With the prevalence of social media, hundreds of millions of users are generating digital traces of their day-to-day life on the web. Boundary control is challenging in this online environment because the need for identity expression might change over time, and the management of co-owned digital traces often involves decision-making with other people. In this talk I will present two recent CHI papers that explore how people interact with social media affordances to negotiate personal and relational boundaries, the difficulties they encounter, and what this implies for supporting better interaction between the space for the self, for relationships, and for public in social media.
Bio:Xuan Zhao is currently a PhD student at University of Michigan School of Information. Her current research focuses on understanding the nature of digital traces on social media in relation to other digital processions, with an emphasis on exploring the relationship between social media data and people's identity and relationships. Xuan holds a M.S in Human-Computer Interaction from Cornell University and a B.A from Shandong University. She has previously worked as a research intern at Intelligent Collaboration group at IBM Research, Facebook UEX Research, and the Socio-Digital group at Microsoft Research Cambridge.

Title:“Facebook is a Luxury”: No Electricity, High Costs and other Barriers to Social Media Adoption in Rural Kenya
Abstract:The New York Times, BBC and other media channels are abuzz with reports about Mark Zuckerberg’s efforts to connect everyone on the planet via Facebook. Missing from these reports are the realities rural African users encounter when trying to access the social media site. In this talk, I present findings from my fieldwork in rural Kenya studying mobile phone owners and social media users to describe how persistent poverty, limited access to technology and unreliable electricity hinder online participation. I draw on these results to discuss new design opportunities, to raise questions about broadening online participation and to highlight the importance of engaging with diverse users on their own terms.

Title:Mindtools: What does it Mean to be Literate in the Age of Google?
Abstract:What does it mean to be literate at a time when you can search billions of texts in less than 300 milliseconds? Although you might think that "literacy" is one of the great constants that transcends the ages, the skills of a literate person have changed substantially over time as texts and technology allow for new kinds of reading and understanding. Knowing how to read is just the beginning of it -- knowing how to frame a question, pose a query, how to interpret the texts you find, how to organize and use the information you discover, how to understand your metacognition -- these are all critical parts of being literate as well.
In this talk Russell will review what literacy is today, in the age of Google, and show how some very surprising and unexpected skills will turn out to be critical in the years ahead. We have created powerful new tools for the mind. Thing is, those tools are constantly evolving and changing even as the things they operate on change as well. This puts us in the position of having to learn how to find tools, and understanding the substrate on which they work. Literacy in these days is not just reading and writing, but also understanding what knowledge tools are available, and how they can be used in interesting new ways.

Title:Interactive Effects of Reach and Receptivity in the Open Collaboration Context: Predicting Open Source Software Project Success
Abstract:Projects vary in their ability to access and leverage the knowledge available across their networks. This paper develops and tests seven hypotheses related to the impact of network reach (distance and diversity of a project’s network alters) and receptivity (ability of the project to leverage network resources) on the success of open source software projects. Results from a study of 170 open source projects support the hypothesis that increases in reach imply increases in access to knowledge and thus have a direct positive effect on technical success. We explore three factors that represent a project’s receptivity to knowledge integration, which represents a critical means of leveraging network resources. These are implementation complexity, discussion interactivity and documentation comprehensiveness. Analysis reveals direct positive effects of discussion interactivity and documentation comprehensiveness on technical success. There are also interactions between reach and implementation complexity and between reach and documentation comprehensiveness. Findings extend the literature on open source software success and have implications for the wider literature on open collaborations. Implementation complexity, discussion interactivity, and documentation comprehensiveness are within the control of project participants, yielding practical implications.
Bio:Sherae L. Daniel completed her PhD in Information Systems with a minor in Econometrics from the University of Maryland's Robert H. Smith School of Business.

Title:Human and Social Interface for Sustainable Living
Abstract:The performance of energy efficient buildings and building systems relies not only on intelligent design and use of appropriate building technologies, but is also largely dependent on the ways in which these advances in ‘smart’ green building systems integrate with occupant use patterns to enhance overall life quality and support long-term behavioral transformation toward energy conservation practices.
Research has shown that while approximately half of the energy used in the home depends on the physical characteristics of a house and its equipment while residents and their behavior influence the balance.1Differences in individual behavior have been shown to produce large variations – in some cases as much as 300% - in energy consumption, even when controlling for differences such as housing, appliances, HVAC systems, and family size.2
This presentation reviews our understanding of existing energy use patterns and adoption/utilization of energy conservation practices in residential and workplace settings. Our intent is to explore the critical human and social dimensions of sustainable building/community design, and to understand those characteristics that enhance inhabitant life quality and support long-term energy conservation practices.
Bio:Dr. Jean Wineman is Professor of Architecture and Associate Dean, Taubman College of Architecture & Urban Planning, University of Michigan. Her research interests focus on the links between characteristics of architectural design and behavioral, educational, and performance outcomes.

As digital devices and internet connected services make their way into increasingly younger hands, parents have new anxieties to deal with. What are children doing with social media? How can parents cultivate constructive behaviors and healthy habits with new technologies?
The National Science Foundation has awarded UMSI assistant professor Sarita Yardi Schoenebeck a three year, $469,519 grant to conduct a wide-ranging study to assess parenting methods for increasing awareness, intentionality, and competency in youths’ social media usage. Schoenebeck notes that shifts in the technological landscape have generated a complex, sometimes fraught, series of parental perceptions relating to technology’s role in their children’s lives: parents hold simultaneously positive and negative views and have difficulty reconciling them.
The study will seek methods for reducing the challenges Schoenebeck identifies through a multi-step approach:
- A series of preliminary studies to identify how parents and children perceive social media use and where perceptions are mismatched
- A trial of mobile phone tools to encourage children to reflect on the content and context of their mobile social network use, along with text alerts to parents encouraging them to establish dialog with their children about social media
- A similar trial which leverages web browser usage among children with laptops and provides them with regular alerts
These studies will be used to generate themes and theories about how children use social media and how parents can be provided with tools to decrease their own anxiety about social media use while increasing the self-awareness and reflective capacity of children who engage with social media. The mobile phone and web-based tools will be made available to the public for adaptation, use, and review.

Understanding and Reducing the User Burdens Associated with Interactive Technologies for Health and Wellbeing
The use of interactive technologies to improve health and wellbeing has grown dramatically over the last two decades. However, there are many reasons why people still do not adopt different types of health technologies, including physical, mental, time, emotional, financial, and privacy demands. In my research, I have been seeking to understand and characterize these user burdens and design novel applications that can help to reduce them and improve access to healthcare. In this talk, I will first give an overview of studies seeking to understand the emotional, physical, and privacy burdens of interactive technologies. I will then describe the design and evaluation of three wellness applications my lab has developed in conjunction with health experts in which we have sought to reduce these burdens: 1) ShutEye, a mobile awareness display for promoting healthy sleep behaviors; 2) Lullaby, an at home capture and access system for monitoring the sleep environment; and 3) Baby Steps, an ecosystem of interactive tools for helping parents track developmental progress in young children. Finally, I will discuss future directions in helping to understand and reduce the user burden of health technologies.

HCI and Smartphone Data at Scale
Today's smartphones have an incredible wealth of data about us: they know who we know, who we communicate with, what apps we run, where we go, and more. Altogether, these new capabilities offer us the opportunity to analyze real-world social networks and human behaviors at a fidelity and scale that previously was not possible. As such, mobile devices can be thought of as a new scientific tool for capturing and understanding real-world interactions, activities, and behaviors.
In this talk, I discuss three threads of work my colleagues and I have been investigating. The first is using smartphones to infer depression in people, by using smartphone data to infer social relationships, sleep patterns, and physical activities.
The second thread is using geotag social media data from thousands of people for urban analytics, to help people understand the character, structure, and dynamics of cities.
The third thread is understanding how to protect the privacy of individuals. I will discuss some of our work in using crowdsourcing to dissect the behaviors of apps and to build better summaries that emphasize unexpected behaviors.

Analyzing Authoritative Conversational Language with Machine Learning
We constantly interpret social cues in our daily life - from members of other cultures, in new environments, and discussing complex topics. As common as these interactions are, it is no surprise that judging the authoritativeness of others is intuitive, almost automatic, for humans. For computational modeling, however, these cues are not so easy. My research builds sociolinguistic insight into machine learning, streamlining their theories when necessary and automating them when possible, to allow for patterns of authoritative behavior to emerge from large collections of conversational data. This talk demonstrates that authoritative language in conversation can be defined in a reliable way; that those cues can be reliably recognized using machine learning, matching human accuracy in judgment of authority and annotation of social behavior; and that the output of that prediction correlates with diverse outcomes, such as interpersonal trust, task success, and cross-cultural communication effectiveness. These results range across conversational domains, from controlled lab studies to the high stakes domains of healthcare and education.
Elijah Mayfield is a Ph.D. student at the Language Technologies Institute at Carnegie Mellon University, and a recipient of the 2011 Siebel Scholarship and the 2013 IBM Ph.D. Fellowship. His research focuses on using machine learning to better understand and recognize social cues in language, with an emphasis on authoritativeness, expertise, and empowerment. In practice, he is using these insights to improve understanding of real-world problems in education and healthcare. Elijah is also the founder of LightSIDE Labs, a startup in Pittsburgh, PA building platforms for automated assessment of student-written texts using machine learning. In 2012, LightSIDE was invited to participate in the ASAP Competition, held by the Hewlett Foundation and Kaggle.com, where those vendors demonstrated that the state-of-the-art in automated assessment matches human reliability. His work with LightSIDE has been highlighted across a variety of news sources including NPR Morning Edition, Education Week, and Science.

The Death of User-Centered Design
In this talk, I will share some nascent ideas about why and how the the field of HCI should move beyond user-centered design in framing problems and creating solutions. In the past three decades, topics of interest within HCI have migrated from usability of desktop computers for office workers to complex, societal problems including healthcare and sustainability. I believe that current HCI approaches, inspired by user-centered design, are insufficient to appropriately take on these new challenges. I propose, instead, that we take a service design approach and conceive of product service systems to look at problems holistically, and to consider the implications of what we might design.
Jodi Forlizzi is an Associate Professor of Design and Human-Computer Interaction at Carnegie Mellon University, in Pittsburgh, PA. She also leads the Human-Systems Interaction Group of the Quality of Life Technology Center, an NSF Engineering Research Center.

The Ethnomathematics of Algorithms: Sensors and the Problem of Little Big Data
Big data is a discourse that enables people imagine new ways that digital information can travel, connect people, and make meanings. The discourse brings together notions of the found object with a notion of the infinitely recombinable, as if all data were related to all other data if thrown into a cloud-like space and stirred around. In this discourse, data is assumed to lack boundaries, and meaning is assumed to be ready-to-hand, just round the corner with enough stirring. Yet it seems that just before the technology industry gets to that corner,it invariably calls for more context, as if adding “more context” were as simple as adding more data. Using an ethnography of home energy monitoring and health monitoring enthusiasts, I show how the cultural imagination of data's infinite recombinability encounters people’s practical experiences with sensor data. The anthropology of number shows that human sensemaking has much to do with sensor data’s linguistic properties. In Peircian terms, it is designed to generate “indexical” forms of meaning. For home energy and health monitoring, data’s indexicality both betrays too much and yet is never sufficient. Sensor data is both very big and very little at the same time. This expansive and yet myopic quality is the source of much consternation, as it forces users to encounter just how complex their own constructs of what constitutes a “healthy body” or an “energy efficient home” really are.

The role of prior beliefs and alluring information in everyday scientific reasoning
In this age of information, new research is reported to the general public on a daily basis. Whether it is an article about drinking red wine to lose weight or a friend telling us who we should vote for, we constantly encounter new claims that aim to influence our behavior. Research has suggested that vivid, anecdotal information may make claims more persuasive and may have an influence on our decisions. This body of research has yielded mixed results, however, and the conditions under which anecdotes exert an influence are unclear. My work examines whether anecdotes affect our ability to think critically about a claim and whether the influence of anecdotes depends on certain dispositional factors such as our prior beliefs.

Crowd Agents: Interactive Crowd-Powered Systems in the Real World
Over the past few years, I have been developing and deploying interactive crowd-powered systems. For instance, VizWiz has the crowd answer visual questions for blind people in less than a minute, Legion allows outsourcing of desktop tasks to the crowd, and Scribe allows the crowd to caption audio in real-time. Overall, thousands of people have engaged with these systems, providing an interesting look at how end users interact with crowd work in their everyday lives. Collectively, these systems illustrate a new approach to human computation in which the diverse and changing crowd is provided the computational support necessary to act as a single, high-quality actor. The classic advantage of the crowd has been its wisdom, but our systems are beginning to show how crowd agents can surpass even expert individuals on difficult real-time motor and cognitive performance tasks.

Using Mobile Phones to Augment Face-to-Face Social Interaction
We see technology as hindering our face-to-face social interactions. Individuals feel isolated by their devices even when surrounded by other people. This happens despite the fact that many of the devices we have in social settings, such as smartphones, are explicitly designed to support social connections. Such devices focus on remote connections at the cost of our immediate social interactions. We try to mitigate the cost of technology in social settings by not using it when with others (“No phones at the dinner table!”). However, rather than fight the creep of technology into our face-to-face interactions, there is an opportunity to build solutions that embrace it. I will present what we have learned through the deployment of several mobile phone applications intended to make you happy when the person you are with pulls out their phone, rather than annoyed. Bring your phone with you to try one of these applications out during the talk.
Jaime Teevan is a Senior Researcher in the Context, Learning, and User Experience for Search (CLUES) Group at Microsoft Research, and an Affiliate Assistant Professor in the Information School at the University of Washington.

Balancing Design and Technology to Tackle Global Grand Challenges
There are many urgent problems facing the planet: a degrading environment, a healthcare system in crisis, and educational systems that are failing to produce creative, innovative thinkers to solve tomorrow’s problems. A balanced approach is required to solve these problems: a balance between design and technology, a balance between government policy and individual behavior change, and a balance between Western and Eastern ways of thinking. Technology influences behavior, and I believe when balanced with revolutionary design, we can reduce a family’s energy and water use by 50%, double most people’s daily physical activity, and educate any child anywhere in the world to a level of proficiency on par with the planet’s best students. My research program tackles these grand challenges by using a new model of interdisciplinary research that takes a long view and encourages risk-taking and creativity. I will illustrate how we are addressing these grand challenges in our research by building systems that balance innovative user interfaces with novel activity inference technology. These systems have helped individuals stay fit, led families to be more sustainable in their everyday lives, and supported learners in acquiring second languages. I will also introduce the World Lab, a cross-cultural institute that embodies my balanced approach to attack the world’s biggest problems today, while preparing the technology and design leaders of tomorrow.

Big data as both a window and a mirror
People create enormous amounts of content in social media such as Flickr, Twitter, Facebook, and Blogger -- and because these media focus on awareness and current activity, most of this content disappears under the sea of the new, never to be seen again. In this talk we'll explore how systems can re-use these data to help create computational, social science, and personal knowledge. We'll use case studies around collaboration in Wikipedia, making sense of relationships in Facebook, and supporting personal reflection using social media to illuminate major themes around re-using these past data, including the value of multi-method approaches, the need to consider what is left out in online contexts, the potential of helping people use these data to better understand themselves, and the value of doing work that combines research, commercial, and personal interests.
Dan Cosley is an assistant professor in information science at Cornell University who does research around human-computer interaction and social media. His high-level research goal is to build systems that leverage people's pre-existing behavior in digital media to create new individual and social goods. These include SuggestBot, a recommender system that uses Wikipedia editing behavior and link structure to help contributors find articles they are interested in and that the community has marked as needing work, and Pensieve, a system that reminds people to reminisce and write about the past by sending them prompts based on content they have created in social media. This work is supported by a 2009 NSF CAREER grant. Along the way, he has studied a number of domains, including recommender systems, tagging, mobile interaction, museum informatics, and online communities. He values interdisciplinary research, sees research experience as a core component of undergraduate as well as graduate education, and prefers work that makes contributions both to academia and to society more broadly.

Student Design Competition
Two professors from MISC are among the first to offer free courses through a groundbreaking new service, U-M and Coursera announced April 18.
Clinical Associate Professor Charles (Chuck) Severance will present a class on the origins and technology of the Internet, while Associate Professor of Information Lada Adamic will present a course on social network analysis.
"A lot of the battles of our society will be played out over the Internet. It empowers people. If we have no idea what it is, how can we participate?” Severance said. “This course is hopefully going to make the average person far more curious, to want to make themselves more involved and a better network citizen. I want people to look at the Internet from the inside out."
An introduction to Severance’s course can be viewed below.
Adamic will focus on the analysis of social networks. "In this course, you will learn about the structure and evolution of networks, drawing on knowledge from disciplines as diverse as sociology, mathematics, computer science, economics, and physics," she wrote. "Online interactive demonstrations and hands-on analysis of real-world data sets will focus on a range of tasks: from identifying important nodes in the network, to detecting communities, to tracing information diffusion and opinion formation."
In the coming months, a total of seven University of Michigan faculty will offer courses on the site, covering topics ranging from finance to fantasy and science fiction. Coursera’s educational approach includes video lectures with interactive quizzes, mastery-building interactive assignments and collaborative online forums.
One U-M course already offered through Coursera is Model Thinking, taught by Scott Page, Professor of Political Science, Complex Systems and Economics. More than 50,000 people signed up for the class, which launched in February. So far, Page’s students have logged more than 1.2 million views of videos developed for the class. Assistant Professor of Computer Science and Engineering J. Alex Halderman will also offer a course on Securing Digital Democracy.
"Our faculty members are eager to share their knowledge globally and our students are equally excited about experimenting with this new approach to learning,” U-M President Mary Sue Coleman said in a statement.
School of Information Professor Paul Resnick and co-author Robert Kraut, along with contributors Sara Kiesler, Yuqing Ren, Yan Chen, Moira Burke, Niki Kittur, John Riedl, and Joseph Konstan, has published Building Successful Online Communities: Evidence-Based Social Design.
This book offers lessons from theory and empirical research in the social sciences that can help improve the design of online communities. The social sciences can tell us much about how to make online communities thrive, offering theories of individual motivation and human behavior that, properly interpreted, can inform particular design choices for online communities. The authors draw on the literature in psychology, economics, and other social sciences, as well as their own research, translating general findings into useful design claims.
The design claims follow a format familiar to former SI529 (and the prior SI684) students: Alternative X leads to Goal Y under Conditions Z or the comparative format Alternative X1 is more effective than Alternative X2 at achieving Goal Y under Conditions Z
For each design claim, the authors offer supporting evidence from theory, experiments, or observational studies.The book focuses on five high-level design challenges: starting a new community, attracting new members, encouraging commitment, encouraging contribution, and regulating misbehavior and conflict. By organizing their presentation around these fundamental design features, the authors encourage practitioners to consider alternatives rather than simply adapting a feature seen on other sites.Jennifer Preece, Professor and Dean of the University of Maryland’s iSchool, says this is "the book we’ve all been waiting for. Students, faculty, and professional developers will learn how online communities function. There’s something for everyone--empirical findings framed in theory, and gems of advice. The authors are remarkable researchers, teachers, and leaders in the field."
Guest Lecture by Tawanna Dillahunt: "Engaging and Connecting Stakeholders around Sensed Data to Support Environmental Sustainable Behaviors"
Tawanna Dillahunt, a soon-to-graduate PhD student from Carnegie-Mellon University will give a guest lecture on “Engaging and Connecting Stakeholders around Sensed Data to Support Environmental Sustainable Behaviors.”
Tuesday, 24 April, 12-1 pm · North Quad 2245 · Light lunch will be served.
Abstract: According to the U.S. Energy Information Administration, Americans consumed 100 quadrillion BTUs of energy in 2008, with personal, individual activities accounting for much of this consumption. Over the past few years, I have designed, implemented, and studied interfaces that reward conservation behavior by sensing and presenting positive feedback about green transportation choices and home energy consumption. I will give an overview of this work and discuss details of two projects: (1) Ubigreen: a mobile tool for tracking and supporting “green” transportation habits and (2) Community Monitor: a home-energy monitoring application that allows community members to engage with one another to share knowledge and information; to compare electricity consumption; and to build community. My results demonstrate the impact of engagement around social sharing, specifically around community energy monitoring in residential communities.
I have also researched barriers and opportunities for saving energy in low-income communities and explored the impact of multi-stakeholder relationships, and socioeconomic factors on conservation behavior.
Guest Lecture: "Does it matter where we test? Asynchronous remote user studies of digital libraries in natural environments"
Date and time: 02/14/2012 - 12:00pm
Location: 2245 North Quad
Speaker: Elke Greifeneder
Elke Greifeneder is a researcher at the Berlin School of Library and Information Science at Humboldt-Universität zu Berlin. In her research she investigates the adaption and the validity of quantitative and qualitative methods for user behavior studies in remote environments, especially in the user’s natural environment. She has a strong interest in user-centered design of digital libraries and has carried out several user studies. She is associate editor of Library Hi Tech. Elke holds a Magister degree in Library and Information Science and French studies from the Humboldt-Universität zu Berlin and will finish her dissertation this spring.
Abstract for talk:
Users access digital libraries from all over the world and at a time of their choosing. A methodological approach that allows researchers to create evaluations where participants can easily take part without being forced to come to a laboratory is desirable. In her talk, Elke discusses whether the data in a participant’s natural environment are similar to data from the same test in a laboratory.
Recent studies in Computer and Information Science compared data from laboratory tests with remote usability test data and discovered no significant difference between the two settings. But these studies created remote test settings that resembled virtual laboratories; they did not consider remote tests in natural environments. In a natural environment, people are accustomed to multi-tasking and, in consequence, are highly distracted. That means the assumption that laboratory data are similar to asynchronous remote test data might not be true for tests in a user’s natural environment, where researchers have no control over a participant’s other activities during the test period.
The talk discusses the validity of indicators like duration, success of task completion and ratings in a natural environment by showing the hard numbers researchers usually collect, and then illustrates these numbers with context information about what (really) happened in the test situation.

Title: Supporting Spatial Awareness and Independent Wayfinding for Pedestrians with Visual Impairments
Authors: Rayoung Yang, Sangmi Park, Sonali Mishra, Zhenan Hong, Clint Newsom, Erik Hofer, Hyeon Joo and Mark Newman
Abstract: Much of the information designed to help people navigate the built environment is conveyed through visual channels, which means it is not accessible to people with visual impairments. Due to this limitation, travelers with visual impairments often have difficulty navigating and discovering locations in unfamiliar environments, which reduces their sense of independence with respect to traveling by foot. In this paper, we examine how mobile location-based computing systems can be used to increase the feeling of independence in travelers with visual impairments. A set of formative interviews with people with visual impairments showed that increasing one’s general spatial awareness is the key to greater independence. This insight guided the design of Talking Points 3 (TP3), a mobile location-aware system for people with visual impairments that seeks to increase the legibility of the environment for its users in order to facilitate navigating to desired locations, exploration, serendipitous discovery, and improvisation. We conducted studies with eight legally blind participants in three campus buildings in order to explore how and to what extent TP3 helps promote spatial awareness for its users. The results shed light on how TP3 helped users find destinations in unfamiliar environments, but also allowed them to discover new points of interest, improvise solutions to problems encountered, develop personalized strategies for navigating, and, in general, enjoy a greater sense of independence.

Title: Social Mechanics and the Social Business
Abstract: In recent years, we have seen a very rapid and widespread growth in the use of social software in enterprise settings. Increasingly, both large and small companies are using this social media technology to manage and influence relationships with partners, customers and employees. Social networking applications are increasingly being tailored for enterprise use: social bookmarking is combined with enterprise search to improve information seeking, social file sharing applications are improving resource sharing, and enhanced personal profiles are helping to locate experts and improve social interaction as a result of enhanced people sensemaking. In this talk, the lessons learned from several social software research projects sponsored by the IBM Center for Social Software will be discussed. In each case study, a venture research approach was employed in which an innovative new social application was designed and deployed at scale. Three main questions will be explored. How can we harness the power of “social recommenders” to simultaneously boost information visibility and allow personalized monitoring and filtering? How can we use social applications to better support a more global organization? And finally, how can we design socially synergistic systems to support innovation?

Student Design Competition
The Association for Computing Machinery (ACM) has announced that School of Information Professor Paul Resnick and his collaborators have won the 2010 Software System Award for their GroupLens Collaborative Filtering Recommender Systems, which showed how a distributed set of users could receive personalized recommendations by sharing ratings, leading to both commercial products and extensive research.
The Software System Award is given annually to an institution or individuals recognized for developing software systems that have had a lasting influence, reflected in contributions to concepts and/or commercial acceptance. The award is based on work that Resnick and his group produced in the early to mid-1990s.
The GroupLens systems show how a distributed set of users could receive personalized recommendations by sharing ratings, leading to both commercial products and extensive research. Based on automated collaborative filtering, these recommender systems were introduced, refined, and commercialized by the team at GroupLens. They then brought automation to the process, enabling wide-ranging research and commercial applications. The team founded Net Perceptions, which provided recommender systems to leading retail and information companies around the world.
Recommender systems draw on machine learning, human computer interaction, ecommerce, information retrieval, databases, and other computer science fields.
Past winners of this prestigious award, which has been presented since 1983, include developers at Apache, Java, Mosaic, and Postscript. The first award was made to the developers of generic operating systems that led to the implementation of UNIX.
ACM is the world’s largest educational and scientific computing society, providing resources that advance computing as a science and a profession.
Three School of Information students and their teammate from the School of Art & Design have won the first-ever Yahoo! Boost Award to continue the development of a custom multi-touch table and “Chance-It!” — an application that uses the table to explore aspects of the creative process.
SI master’s students Yi Wei Chia and Stan Lin, SI Ph.D. student Jessica Hullman, and their teammate Zhang Zhang were tapped to receive this unique award.
Their project was one of six GROCS (Grant Opportunities [Collaborative Spaces]) 2010 projects supported by the University’s Digital Media Commons this year. GROCS provides collaborative space, equipment, and funding for students to engage in interdisciplinary research of their own design. Approximately 50 projects are proposed to GROCS each fall, of which four to six are selected for funding. Another project selected by GROCS for development was Zydeco, which has one SI team member, Alex Pompe and one Computer Science and Engineering team member, Alex Kuhn.
The Yahoo! Boost award was created specifically to further the development of a GROCS project, according to Don McGillen, Yahoo! senior manager for campus relations. Most Yahoo! awards are for best projects; this is the only Yahoo! award to help develop a promising project.
The award will allow the team to move the project toward their goal to make both the table and the application accessible beyond the U-M community. Chia’s work this summer will include publishing construction drawings for the table and improving its software interface so that novice programmers can more easily develop custom applications for it.
“Conceivably, tables modeled after this one could become resources for schools or museums with relatively small budgets,” says Linda Knox, GROCS program manager.
Over 90 teams entered the competition from around the world and Michigan was the only school with two teams selected for semifinals, Night Beacon and Mibo (Malhar Gupta, Katie McCurdy, Honor Potvin, Kimberly Eunkyoung Song, and Xiaowen Zhang). These two teams have been displaying their posters at CHI, the world's most prominent human computer interaction conference, along with 10 other teams. Night Beacon was among four teams selected for the finals, consisting of a short presentation from each team today.
MISC has historically had a very good showing in the CHI student design competition.
- 2009: SI students won first place with TreasureHunter, a project by Sang Koh, Amy Kuo, Debra Lauterbach, Noah Liebman, and Andrea McVittie. A second project, MIFresh, with members Maureen Hanratty, Geoff Ho, Jiang Yang, and Xiao Wei, took second. Three other MISC teams - WantKnot, LocalBuy, and eXtend - were semifinalists.
- 2008: doGooder came in second, and teams Portalis and Duando were semifinalists.
- 2007: altVerto won first place, and teams TxtBus and Carloop were also seminfinalists.
- 2006: Fitster placed third.

David Kieras is a Professor of Electrical Engineering and Computer Science and of Psychology. His primary general research field is applied and theoretical cognitive psychology, with specific interests in human-computer interaction, cognitive simulation modeling, human performance, complex human learning, and natural language processing.
Prof. Kieras' most prominent contributions to HCI have come in the form of computational models of human performance, starting with his work with Peter Polson on the Cognitive Complexity Theory, epitomized by the classic 1985 International Journal of Man-Machine Studies paper, which provided a seminal application of production systems to produce quantitative accounts of performance time and knowledge transfer from one interface task to another. Viewing production systems as an implementation of GOMS models, he developed NGOMSL as a practical predictive notation to for GOMS models. With Scott Wood, he created the GLEAN system for computational simulations of GOMS models, and with Ruven Brooks he developed an approach to task analysis and the design of functionality based on higher-level GOMS models. With David Meyer, he developed the EPIC cognitive architecture to integrate perceptual, motor, and cognitive performance, pioneering the rigorous application of cognitive architectures to the fine-grain modeling of multimodal user interaction and multitasking performance.
