Anyaway this is NOT the EXOS Dextrous Hand Master: it is a force
feedback device designed by Dr. Burdea at Rutgers University, like
Zyzzy says.  It is not even a commercial product, even if I guess this
WAS to be sold by VPL (with the name of DataGlove FBX)... until
happened what happened at VPL. (BTW any news or point of contact for
VR Builder??)

There's another extensive article describing this device, written by
the ones who made it, on the first issue of Presence, "A Portable
Dextrous Master with Force Feedback"
