MagicMouse, a three-dimensional computer mouse was designed by a team of five WPI undergraduates –
…the mouse uses an array of receivers to track the motion of a tiny ultrasonic transmitter worn on the index finger like a ring. The unique design, the first radical change in the computer mouse in more than 40 years, makes it possible to control and manipulate items on a computer screen just by pointing at the monitor.

I think these guys are a bit behind. I have a P5 “power glove” mouse that does the exact same thing(only with IR instead of ultrasonic) PLUS it allows you to use your fingers as buttons for the mouse. That last part is the best cause you act as though you’re clicking your mouse button and it detects the movement through special sensors that measure the bend of each finger.
Thing is, when I bought mine they were less than $20, now they’re apparently $80. Eeek.
Its not a new concept to use time of flight ultrasound triangulation to get position information in 3D space. It should be noted that with only one transmitter tilt data is not captured and so you can’t just point rather you must hover over the area.
Nice project though.

The Nintendo Power Glove worked this way, too.
