Forwarded by ---------------- Original message follows ---------------- From: To: Doug Bowman Date: Tue, 25 May 1999 10:18:27 +0900 Subject: Re: Virtual vs. real manipulation -- Hi, Doug, FYI, As far as I know, my intimate seniors, Dr. Kitamura at Osaka Univ. and Dr. Noma at ATR had been studying performance of object-stacking task in a real vs. a VE. Though they used magical interaction (a kind of snapping), they tried to make real interaction as possible by using realtime collision detection and two-handed haptic interfaces. I think their research suits your interest. Maybe you already know them... Yoshifumi Kitamura, Amy Yee, and Fumio Kishino.
