- 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"
