I agree that Doug's question only makes sense for Realistic VEs. But what should not be forgotten is we will never be able to construct perfectly realistic VEs, and in terms of lack or incorrectness of any physical properties, all 'Realistic' VEs are 'Magic' VEs in a certain extent. . In this context, differences between the real world and such VEs may affect both well and badly (e.g., the efect of gravity and friction may go either way) depending on the task. And unfortunately, VEs often get away from real by trying to make VEs real..! For example, the more the objects, the slower the graphics. And the more we add multimodal devices, the more awkward the whole system be. Things go better, but we all have such dilemma, don't we ? Anyway, I think the performance comparison only is useless. It'd be useful with detailed configuration data (still, only useful for researchers ? :-)) P.S. please change my e-mail address of the ML from kiyosi-k@is.aist-nara.ac.jp to kiyo@crl.go.jp ---- Kiyoshi KIYOKAWA Multimedia Communications Section, Communications Research Laboratory, Ministry of Post and Telecommunication, Japan Email: kiyo@crl.go.jp / Tel/Fax: +81-42-327-6250/7941
