Sounds similar to something I tried about 4 to 5 years ago that used ultra- sonics and a serial port. Seemed like a great idea but turned out less than stellar for most computer work. To move your finger around in mid-air requires gross motor control that, for most people, is not too well refined. To move mice and trackballs requires fine motor control which is usually highly precise. I tried it for about a month and kept clicking on the wrong menu item, selecting the wrong object on screen, etc. Finally gave up on it. OTOH, the coolest thing about it was it detected z coordinates as well as x and y. It came with a couple games that utilized that feature. It worked pretty well for things like ring toss, but I wouldn't want to try to virtual sculpture with it.
