Virtual reality (VR) is usually described by the media as a particular coll
ection of technological hardware: a computer capable of 3-D real-time anima
tion, a head-mounted display, and data gloves equipped with one or more pos
ition trackers. However, this focus on technology is somewhat disappointing
for communication researchers and VR designers. To overcome this limitatio
n, this paper describes VR as a communication tool: a communication medium
in the case of multiuser VR and a communication interface in single-user VR
. The consequences of this approach for the design and the development of V
R systems are presented, together with the methodological and technical imp
lications for the study of interactive communication via computers.
