Abstract:

The report describes the results of the evaluation of a videoconference system carried out for the US Defense Advanced Research Projects Agency. The author spent three weeks in 1982 running and observing videoconferences held between two offices in the Air Force Manpower and Personnel Center on the Randolph Air Force Base in San Antonio, Texas. The videoconference system used a very compressed video image. The participants were able to retrieve and jointly create graphics using the Shared Graphics Work Space SGWS. The meetings held over the videoconference system were, by and large, natural, successful and, at times, very animated. Participants appeared to automatically compensate for some of the restrictions imposed by the medium, by for instance, checking verbally that each other was following the discussion. In comparison with the results from other full motion videoconferences, however, users of this system were more likely to be dissatisfied with their meeting and tended to feel that meetings took longer. Whereas the previous research tended to show the teleconferences were usually shorter than similar face to face meetings. Most of the dissatisfaction concerned the reliability of the equipment and specific aspects of the SGWS. A number of suggested improvements have been put forward in this report.
