Well, I like the idea of using LCD displays, since prolonged exposure to CRT's and close range is bad for you. On of the nurses where I'm working this semester has an LCD TV. Not that bad, though the quality depends on your viewing angle (or that lack of change in your angle) this is no problem to us, where-as the displays will be slaved to your eyes (ie. helmet). (If your going to flame me on CRT radiation bullshine, save it, at the hospital, I see CRT and MRI effects on people every day). ANYWAY, I realy liked the LCD, and saw major VR applications with them. BTW- Would someone tell me what kind of sensor it is to tell head rotation? (ie. change in direction of looking?) and with the displays, people dont allways look straight ahead, we "look with our eyes" more than we think we do. The display would have to be able to cover a large field of view with the areas that we can look at with our eyes. does anyone want to figure this out? Im going to bed now, but maybee I work on it tomarrow at work. :-) ps. VR would have GREAT protential in the Medical Field. I wont go into it now, but think about it. -- David C.
