In 1993 and 1994, instructors and students of architecture at several universities around the world* collaborated briefly on two “virtual design studio” projects. Using off-the-shelf technology of the time-email, CU-See-Me internet video, international conference calls, and exchange of CAD drawings, images, and Quicktime animations-this ambitious project explored the possibility of bringing together diverse members of an international design team together to collaborate on a short term (two week) project. Central to the “Virtual Design Studio” was a'digital pinup board', an area where participating designers could post and view drawings and textual comments, video links and email exchange provided the media for direct communication media about designs. A report on the project [21] makes clear that the process was not without technical difficulties: a significant amount of communication concerned scheduling and coordinating file formats, disappointingly little was devoted to discussions of design issues. Although it's clear that many of the minor technical problems that inevitably plague a forward-looking effort like the Virtual Design Studio will be solved in the near term, the project also reveals the need for research on software and design practices to make computer mediated design collaboration realize its attractive promise.
