Ten years ago, I designed, patented, and produced the first touch-less mouse...The Motion Mate.
I used three Sharp IR detectors, an E PROM, I wrote the firmware in PIC and the drivers in C. I used phase space algorithms to perform real time predictive co-ordinate shifts derived by repetitive sampling positions of the users’ hands by target acquisition via triangulation.
It worked perfectly. I even designed a 3D game of Jenga for it.
That being said. There is a big down side.
Try this exercise:
Stand for five minutes moving your hands around, perhaps pretending to chisel a statue out of granite.
It’s taxing, uncomfortable, and exhausting...if not down right damaging!
