From: Robert Lougher Subject: Re: HUMAN-FACTORS: Long term immersion in VR Date: July 3, 1996 I am trying to get a VR based training project setup for the USAF and have jumping all over the nation gathering SIGNIFICANT information on VR where ever I can find it. Recommend you go to Armstrong Labs at Brooks AFB. http://www.brooks.af.mil/al. I found there multiple studies based on physical vs VR. My guess is most is related to pilot simulator studies. Also, read Mr. Pierce's post - my only experience was standing as walking around with a primitive HMD. Very little vertigo but visual focus was impaired for a few seconds. Hope this helps. Robert W.
