The Gametrak<\/a> system is a real 3DOF tracker. Well two actually, one for both hands. They claim the latency is really low (0 actually), but I’ll wait to have my hands on one of these before assuming it’s true =)<\/p>\n Anyway this seems like a good toy to play with, I’ll try it =). At 30\u00e2\u201a\u00ac<\/a>, it may be very worth it !!<\/p>\n","protected":false},"excerpt":{"rendered":" QuickWrite<\/a> is an input method created by Ken Perlin<\/a> so that \\”you shouldn\\’t ever need to pick up the pen (ie: no clicking, only gliding).\\” So today I played in Virtools with the idea of using Natural Point\\’s TrackIR<\/a> as an input device.

\nStrings attached to your hands help the system measure
\nthe distance and angles from the base item on the ground.
\nIt then determines the x,y, and z position of both your hands.<\/p>\n![\\\"\\\"](\\\"http:\/\/mrl.nyu.edu\/~perlin\/experiments\/quikwriting\/ql.gif\\\")

\nI really like this input method and think it might be useful for symbolic input in VWs.<\/p>\n
