Media Spaces: Environments for Informal Multimedia Interaction
Wendy E. Mackay · 1999
Distributed organizations, with distributed cooperative work, are a fact of life. How can new technologies help? Distributed video is an appealing choice, carrying more contextual information than voice alone and, arguably, better at conveying subtle cues, such as the emotional states. Although new commercial systems are being introduced, they focus primarily on providing new technology. Most are based on relatively simple extensions of two existing models of communication: formal meetings become videoconferences and telephones become videophones. However, research in computer-supported cooperative work has tried to emphasize the user, with models based on Shared Workspaces (to support shared work on a common task), Coordinated Communication (to support structured communication to serve a specified purpose), and Informal Interaction (to support informal, unplanned and unstructured interactions). Although mediaspaces can incorporate all three, they emphasize informal communication, providing people working together at a distance with interactions that they take for granted when they are co-located. This chapter describes some of the pioneering work in media spaces, with more detailed descriptions of our own work at Rank Xerox EuroPARC (RAVE for our own use in the laboratory and WAVE, to support engineers working collaboratively between facilities in England and the Netherlands), concluding with a discussion of the technical, user interface and social issues involved in designing media spaces.
