Lindeman" To: 3-D User Interaction Mailing List <3d-ui@hitl.washington.edu> Subject: Re: Virtual vs. Real Manipulation Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Status: RO Okay, I've been lurking long enough! Nice to see so much activity on the list! (BTW, Doug, how did it go?) I, for one, would like to conduct a study comparing real and virtual manipulation. Just throwing out some ideas here: 1. You may remember the game "Operation" from your childhood (for those who don't, this was an electric game that required players to take turns removing plastic bones from metal slots from a patient using a pair of metal tweezers. If you touched the sides of the slot, a contact would be closed, and a buzzer and light would be triggered.) It would be pretty straightforward to build physical and virtual systems that would (arguably) be equivalent. 2. Path tracing could similarly be done using a "wire-and-loop" type of electric system. (I remember reading a paper on a virtual system that did this...anyone have the reference?) Another sort-of side question would be how well immersive VR systems compare with standard windows interfaces. (This is probably a function of my own work in 2-D interaction in 3-D worlds.) It would be interesting to compare a touch screen interface with a virual touch screen. Anyway, just a few musings....Any comments? -Rob --- _/ _/ _/ _/ * Robert W.
