I seem to remember an experiment whereby you run to hoses in a helix about each other with an insulater between them. If you then run cold water in both and put you hand around the outside, you will feel a sensation of cold. If hot, then you feel hot. (In your hands obviously) If you run hot and cold, one in each tube, then you will have a sensation of pain by nerve induction. If this is made into a small glove using tubing, then you could also have a "warning" type device; however, this is a false pain, and does no "real" damage. The pain can be described as a "cold burning, but not quite". Just a thought from VR tactile synthesists. Also, how about a variable tip/pad unit run on piezo-electric crystal combined with the crystal/fluid matrix to provide a sense of presure on the positive side of the object held in VR simulations with the added effect of causing a general stiffening associated with holding an object. The pad/tip is there to provide a sense of tactile orientation. -rick.
