ABSTRACT
We outline some of the benefits of shared visual information for collaborative repair tasks and report on a study comparing collaborative performance on a manual task by workers and helpers who are located side-by-side or connected via audio-video or audio-only links. Results show that the dyads complete the task more quickly and accurately when helpers are co-located than when they are connected via an audio link. However, they didn't achieve similar efficiency gains when they communicated through an audio/video link. These results demonstrate the value of a shared visual work space, but raise questions about the adequacy of current video communication technology for implementing it.
