The Effect of Audio and Visual Aids on Task Performance in Distributed Collaborative Virtual Environments
Résumé
Collaborative virtual environments (CVE) has recently gained the attention of many researchers due to its numerous potential application domains. Cooperative virtual environments, where users simultaneously manipulate objects, is one of the subfields of CVEs. In this paper we present a framework that enables two users to cooperatively manipulate objects in virtual environment, while setting on two separate machines connected through local network. In addition the article presents the use of sensory feedback (audio and visual) and investigates their effects on the cooperation and user's performance. Six volunteers subject had to cooperatively perform a peg‐in‐hole task. Results revealed that visual and auditory aid increase users' performance. However majority of the users preferred visual feedback to audio. We hope this framework will greatly help in the development of CAD systems that allow the designers to collaboratively design while being distant. Similarly other application domains may be cooperative assembly, surgical training and rehabilitation systems.
