Hancock, Jeff, Birnholtz, Jeremy, Bazarova, Natalya, Guillory, Jamie, Perlin, Josh and Amos, Barrett (2009): Butler lies: awareness, deception and design. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 517-526. Available online
“Instant messaging (IM) is a common and popular way for co-workers, Friends, and family to stay in touch, but its always-on properties can sometimes lead people to feel overexposed or too readily available to others for conversation. This, in turn, may lead people to deceive others about their actual status or availability. In this paper, we introduce the notion of the "butler lie to describe lies that allow for polite initiation and termination of conversations. We present results from a field study of 50 IM users, in which participants rated each of their messages at the time of sending to indicate whether or not it was deceptive. About one tenth of all IM messages were rated as lies and, of these, about one fifth were butler lies. These results suggest that butler lies are an important social practice in IM, and that existing approaches to interpersonal awareness, which focus on accurate assessment of availability, may need to take deception and other social practices into account.”

Leshed, Gilly, Perez, Diego, Hancock, Jeffrey T., Cosley, Dan, Birnholtz, Jeremy, Lee, Soyoung, McLeod, Poppy L. and Gay, Geri (2009): Visualizing real-time language-based feedback on teamwork behavior in computer-mediated groups. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 537-546. Available online
“While most collaboration technologies are concerned with supporting particular tasks such as workflows or meetings, many work groups do not have the teamwork skills essential to effective collaboration. One way to improve teamwork is to provide dynamic feedback generated by automated analyses of behavior, such as language use. Such feedback can lead members to reflect on and subsequently improve their collaborative behavior, but might also distract from the task at hand. We have experimented with GroupMeter -- a chat-based system that presents visual feedback on team members' language use. Feedback on proportion of agreement words and overall word count was presented using two different designs. When receiving feedback, teams in our study expressed more agreement in their conversations and reported greater focus on language use as compared to when not receiving feedback. This suggests that automated, real-time linguistic feedback can elicit behavioral changes, offering opportunities for future research.”

Birnholtz, Jeremy, Mak, Clarissa, Greenberg, Saul and Baecker, Ronald M. (2008): Attention by proxy? issues in audience awareness for webcasts to distributed groups. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 103-106. Available online
“Instructor/student interaction in e-learning environments can positively impact both student learning and instructor satisfaction. In online webcast lectures, however, interaction can be difficult because instructors lack basic awareness information about their remote students. Our goal is to better understand the kinds of awareness information that instructors should have if they are to interact frequently and effectively with their students in e-learning environments. We conducted an exploratory study -- via interviews and observations -- of instructor attention in face-to-face classrooms at a large university. Our results imply that a webcast system should provide instructors with overview and detailed data about their students, but that this detailed information should not be displayed publicly.”

Ranjan, Abhishek, Birnholtz, Jeremy and Balakrishnan, Ravin (2008): Improving meeting capture by applying television production principles with audio and motion detection. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 227-236. Available online
“Video recordings of meetings are often monotonous and tedious to watch. In this paper, we report on the design, implementation and evaluation of an automated meeting capture system that applies television production principles to capture and present videos of small group meetings in a compelling manner. The system uses inputs from a motion capture system and microphones to drive multiple pan-tilt-zoom cameras and uses heuristics to frame shots and cut between them. An evaluation of the system indicates that its performance approaches that of a professional crew while requiring significantly fewer human resources.”

Wu, Mike, Birnholtz, Jeremy, Richards, Brian, Baecker, Ronald M. and Massimi, Mike (2008): Collaborating to remember: a distributed cognition account of families coping with memory impairments. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 825-834. Available online
“Individuals with cognitive deficits and their families are prime examples of collaborative "systems" that seek to perform everyday tasks together. Yet there has been little investigation into how these families communicate and coordinate in basic tasks like remembering appointments. In this paper we take a distributed cognition approach to studying ten families struggling with amnesia through nonparticipant observation and interviews. Our data show that the families work closely together as cognitive systems that must compensate for memory volatility in one of the members. We explore our participants' strategies for overcoming these difficulties and present lessons for the design of assistive technologies, highlighting the need for redundancy, easy and frequent synchronization, and awareness of updates. We conclude with implications for distributed cognition theory.”

In: Proceedings of ACM CSCW08 Conference on Computer-Supported Cooperative Work 2008. pp. 427-436. Available online
“Coordinating goals, schedules, and tasks among collaborators is difficult, and made even more so when there are disciplinary, geographic and institutional boundaries that must be spanned. Designing CSCW tools to support coordination in these settings, however, requires an improved under-standing of the constraints and conflicts that impede effective collaboration. We present findings from a study of distributed collaborations between academic surgeons and biomedical engineering researchers. These two groups differ significantly in their work priorities and institutional contexts, but are nonetheless able to work together and co-ordinate effectively. They accomplish this via human mediation, frequent ad hoc communication, and optimizing the use of their limited face-to-face interaction opportunities.”

“This paper presents an observational study of face-to-face university classrooms and provides preliminary design principles for improving interactivity in "webcast" presentations. Despite the fact that participation and interaction patterns appear to depend heavily on presentation style and class size, useful patterns were observed and analyzed. Design principles presented include the need to support rapid changes in floor control, multiple types of presentation technologies, and the subtleties of awareness between the audience and presenter.”
