        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.
