The roles of sensory modalities in collaborative virtual environments (CVEs)

Computers in Human Behavior, 24(4), 1404–1417.

By: C. Nam*, J. Shu & D. Chung

author keywords: collaborative virtual environments (CVEs); haptic feedback; presence; copresence; collaboration
TL;DR: Results of the study indicated that the task performance, perception, and user behavior inCVEs can be affected due to supported sensory modalities, and the multiple sensory information types that are required to perform the task at hand should be provided to effectively support collaboration between people in CVEs.
