I am looking for tactile feedback devices to incorporate into a
motion-tracking system -- for example, to let the person being tracked
know if they are out of range of the motion tracker.  I would need
these devices to be small and wireless.  Our original idea is have
small vibrating units (such as finger rings) that would vibrate as
long as they were receiving a "you are in range" signal from the
tracking device. I suppose this would have to be done with a radio
receiver/transmitter.  In concept this is very similar to a commercial
pager -- something that vibrates when it gets a signal.

Any information would be greatly appreciated -- either about existing
products, people working on similar projects, or ways to hack
something like this together.  Also any other newsgroups/web sites
that have information on tactile feedback devices.

Many thanks,
