slide to unlock"... I am actually offended that Lucent filed a patent in 1998 (awarded in 2001) for VR-based interface. VPL Research had already built goggle/glove systems 13 years before Lucent filed that patent. Hell, I had already played Dactyl Nightmare (image right) before that patent was filed. In fact, take a look here and see what prior art you find.
