From: draperjv@ornl.gov Subject: SCI: Presence, Telepresence, and Immersion Organization: Oak Ridge National Laboratory Presence, telepresence, and immersion are psychological phenomena. Is anyone out there trying to measure them in a reliable and valid fashion? Anyone know of any research going on to better define and measure these phenomena? JVD [Slater, M. and Usoh, M. (1993).
