Please - you are not trying to conduct a conversation based upon Xbox
experiences - are you? Xbox has an entirely different purpose and
objective.

Why is the Xbox so wrong a thought? A computer senses the motion and
reacts pretty closely to the type of motion. Sounds like it could be
adapted very well to a saw safety device.
Relative motion isn't going to save a finger, and absolute
positioning that can tell a finger from the lumber you want to cut is
going to be virtually impossible. Telling the difference between wood
and flesh in CONTACT with the blade is difficult enough - and that
technology is the core of HALF of the SS patent.
