Re:How about a 3D space mouse? (Score 1)

The hand gestures in Minority Report look really great, but imagine how tired your arms/hands/fingers would get, even after a short amount of time. The beauty of a conventional mouse is that you can move the cursor across the entire screen with only an inch of movement.

I suppose a therimin-like interface could be made that was intended to be used from a sitting position, with small movements of the hands and fingers. It might take a good while to learn to use though.
