Spatial workspace collaboration: a SharedView video support system for remote collaboration capability

ABSTRACT

Collaboration in three-dimensional space: “spatial workspace collaboration” is introduced and an approach supporting its use via a video mediated communication system is described. Verbal expression analysis is primarily focused on. Based on experiment results, movability of a focal point, sharing focal points, movability of a shared workspace, and the ability to confirm viewing intentions and movements were determined to be system requirements necessary to support spatial workspace collaboration. A newly developed SharedView system having the capability to support spatial workspace collaboration is also introduced, tested, and some experimental results described.
