Physiological Reaction and Presence in Stressful Virtual Environments
A common measure of the quality or effectiveness of
a virtual environment (VE) is the amount of presence
(the sense of being there) it evokes in users. Experience
the dramatic VE reported in the SIGGRAPH 2002 Paper,
Physiological Measures of Presence in Virtual Environments,
that demonstrates that heart rate is a reliable, valid,
sensitive, and objective measure of presence in stressful
Measurement of effectiveness ("presence")
of virtual environments.
For any VE that elicits a physiological reaction (stressful,
relaxing, or otherwise), it is possible to construct
a physiological measure of presence. These physiological
measures of presence can be used to understand which
aspects of the VE are important for improving presence.
With this knowledge, VE practitioners could design more
