The Collaborative and Multimedia Group conducted research from the spring of 1998 to the fall of 2001, at which time its members moved to other groups. Subsequent work can be found on the pages of individual group members. This is a summary of the group’s projects and papers. Papers written in 2001 are updated to reflect final status.
Online communication, collaboration, and communities are the basis for exciting new application areas for computers. Our group explored new technologies and novel applications in these areas. For online communication and collaboration, we strove to make audio and video as flexible and easy to use as text. We worked to help people access and collaborate around multimedia, in real-time and on-demand. We explored new communication paradigms and techniques to increase awareness and interaction among geographically distributed participants, and exploring how our technologies apply in the consumer space, developing enhanced media-browsing interfaces and services for interactive television. For online communities, we explored how sociological principles and data mining techniques can provide a framework for enhanced services, including formation of peer support networks, development of reputations, and incentive structures that encourage continued contribution for the collective good.
