Physiological Measures of Presence in Virtual Environments
Michael Meehan, Brent Insko, Mary C. Whitton, Frederick P. Brooks · 2001
Virtual environments (VEs) are the most advanced human-computer interfaces yet developed. Researchers, by the development of new methods, theories, and technologies, have endeavored to make effective VEs. The definition of effectiveness changes based on the application of the VE. For flight simulators, training transfer is important. For architectural walkthroughs, accurate perception of space is important. For treatment of phobias and post-traumatic stress disorders, presence – evoking in patients the feeling that they are near the source of their phobia or stress – is important [Hodges, 1994]. It is on this last concept, presence, that this paper focuses.
