I'm doing my defense next week, but I still have time to post this, so surely you'll have time to reply... :-) A question was posed to me recently and I thought I would throw it out to the group to see what you thought. I'll post my own answer in a few days. In terms of performance (speed and errors), how far are we from real-world performance on a simple, within-reach object manipulation task in VR? That is, if you have a set of 4 blocks that you want to place one on top of the other, how much worse is it in VR than in real life? Are we close to the optimal we can do in VR? If not, what would cause performance to leap to the next level? Are these even the right questions to be asking? Chew on that and reply to the group... --Doug -- Doug Bowman, Ph.D. Candidate College of Computing, GVU Center, Georgia Tech Room 388 CRB, (404) 894-5104 bowman@cc.gatech.edu http://www.cc.gatech.edu/~bowman/
