The magic window : balancing privacy and awareness in office settings

Co-workers who are physically distributed in the same building often obtain information about others through the windows in office doors. Using the information gathered by looking through the window, they can determine whether it is a good time to initiate a conversation with the occupant. There are, however, two problems with ordinary glass windows. First, there are times when the window does not provide enough information, such as when the occupant is away. Second, there is potential to violate the occupant’s privacy; as a result of the privacy risk, people often cover their windows entirely. If office windows are to work efficiently as a support for collaboration, there must be a balance between awareness and privacy. In this research, I augmented the functions of a physical office window with a computer-mediated replacement called the Magic Window. The Magic Window collects video of the occupant, mediates the signal in various ways, and then presents the altered view on a screen that replaces the glass window. The Magic Window provides a better balance of awareness and privacy in office settings by allowing occupant to differentiate the amount of awareness information based on the viewer. The Magic Window system was tested in an eight-month field trial. The trial showed that the augmented window did provide a balance of privacy and awareness, and also raised a number of issues that will aid the design of future design of co-present media spaces

Psychology

The Internet explosion and broad interest in collaborative technology have driven increased interest in the field of computer-supported cooperative work (CSCW). Historically, behavioral research on CSCW applications has reflected a strong influence from ethnomethodology. This article argues that the CSCW community should adopt a stronger orientation to other social science disciplines, particularly psychology. Greater attention to the psychological literature provides three benefits. First, psychologists offer well-validated principles about human behavior in group and organizational contexts that are relevant to CSCW research. Second, psychologists offer reliable and proven measures of human behavior that, if adopted by CSCW researchers, can provide a uniform basis for comparison across studies. Finally, psychologists offer data collection and analysis methods that identify salient and generalizable features of human behavior, which may lead to the development of universal principles of CSCW design.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68835/2/10.1177_089443939801600106.pd

Improving availability awareness with relationship filtering

Awareness servers provide information about a person to help observers determine whether a person is available for contact. A trade -off exists in these systems: more sources of information, and higher fidelity in those sources, can improve people’s decisions, but each increase in information reduces privacy. In this thesis, we look at whether the type of relationship between the observer and the person being observed can be used to manage this trade-off. We conducted a survey that asked people what amount of information from different sources that they would disclose to seven different relationship types. We found that in more than half of the cases, people would give different amounts of information to different relationships. We then constructed a prototype system and conducted a Wizard of Oz experiment where we took the system into the real world and observed individuals using it. Our results suggest that awareness servers can be improved by allowing finer-grained control than what is currently available

Enabling Polyvocality in Interactive Documentaries through ‘Structural Participation’

Recent innovations in online, social and interactive media have led to the emergence of new forms of documentary, such as interactive documentaries (‘i-Docs’), with qualities that lend themselves to more open and inclusive production structures. Still, little is known about the experience of making and/or participating-in these kinds of documentary. Our two-year in-the-wild study engaged a large community-of-interest in the production of an i-Doc to explore the ethically-desirable yet challenging aim of enabling multiple subjects to have agency and control over their representation in a documentary. Our study reveals insights into the experiences of participating in an i-Doc and highlights key sociotechnical challenges. We argue that new sociotechnical infrastructure is needed, that frames both ‘executory’ and ‘structural’ forms of participation as symbiotic elements of a co-design process
