From: "PSOTKA, JOSEPH" Subject: SCI: Vr and Psychology Date: 23 Oct 92 15:48:00 EDT Quote++++++++++++++++++++++++++++++++++++++++++++++++++++ While using a VR system, I was just standing still but using buttons to move back/forward, etc, I found myself leaning backwards/forwards whenever I started and stopped moving. I thought this was quite interesting, but I'm more of a programmer than a psychologist so I don't know much about psychological effects of VR. Quote++++++++++++++++++++++++++++++++++++++++++++++++++++ This is a well-known but stiill poorly understood phenonmenon studied by many psychologists. One well-known researcher in the area I. P. Howard has called this "vection" For a general work, see: Howard, I. P. (1982). Human Visual Orientation. New York: Wiley. A more recent treatment of a broad spectrum of things like this is: Ellis, S. R. (Ed.), (1991). Pictorial Communication in Virtual and Real Environments. London: Taylor and Francis. Thanks for pointing this out. It would be very helpful to the science if everyone collected such blindingly obvious but often not understood phenomena and put a little note in. Its like discovering new stars palnet s and asteroids. Most of them have been discovered, but every now and then you can hit the jackpot and really uncover something important. Keep up the good work!
