I read once of a virtual reality application for molecule construction.
You'd put on your gloves and waldos & be able to move around molecules
and try to fit them together. The feedback for how well they fit together
was communicated via the "resistance" experienced in the gloves.

Does anyone out there know anymore about this?

Take a look at last year's SIGGraph proceedings. There was a set of 2 or 3 presentations of systems that give force-feedback, including one that fits the above description pretty well (minus the gloves) -- Blair MacIntyre, Computer Graphics Lab Dept. of Computer Science, University of Waterloo, Waterloo, ON, Canada, N2L3G1 {bmacintyre@{watcgl|violet|watdragon}}.{waterloo.edu|uwaterloo.ca}

From an article I read in a Siggraph review; it was a prototype system made to see how much of an improvement VR would be to experts who already model these things in their heads (as is usually the case). The results were better than expected. The skill and ease with which the experts were able to model and create weird molecules was fabulous. The defeater was the cost and clumsyness of the interface however. I don't know if any further work was done along these lines. Possibly just waiting for 'advances in technology' to make it available. Is all. -- Mark Tilden: _-_-_-__--__--_ /(glitch!) M.F.C.F Hardware Design Lab. -_-___ | \ /\/ U of Waterloo. Ont.

One thing to take into account is that the prototype was built by canabalizing a 15-20 year old robot arm. The clumsiness/cost would be affected by this to a large degree. Well, perhaps not the cost. Actually, Mark, I think the software for force-feedback would make a spiffy real-time project, don't you? :-) -- Blair MacIntyre, Computer Graphics Lab Dept. of Computer Science, University of Waterloo, Waterloo, ON, Canada, N2L3G1 {bmacintyre@{watcgl|violet|watdragon}}.{waterloo.edu|uwaterloo.ca}

Project GROPE has been one of Fred Brooks' things for many years. possibly ever since he escaped from overseeing the development of IBM OS/360 aka "OS the Bitch Goddess". Lance

My favorite idea involving force feedback is extremely simple: a mouse that simply will not move into illegal/protected parts of the screen. marshall -- /****************************************************************************/ /* Marshall Gene Flax '89 (609)258-6739 mgflax@phoenix.Princeton.EDU */ /* c/o Jack Gelfand|Psychology Dept|Princeton University|Princeton NJ 08544 */ /****************************************************************************/
