A computer could look at the image and tell whether your finger are in
the path before you even push the wood piece casing an alarm.

My camera tells when 5 people are smiling and then takes the picture!

Trouble is how many accidents happen straight in instead of hand
jerking against the side of the carbide? This is why the Saw-Stop
people are lying about the significance of the mechanism. Drag the side
of your hand against the carbide on the side of the blade and then have
it snap down, dragging it across your skin may lower the damage caused
in a contact accident but not prevent it, like they imply.

Saw-Stop bends the facts in the argument and then wins by simple facts
that may not be relevant to TS accident statistics.

A computer with a video camera could watch you as you make the cut. It
would "know" what the saw looked like and a piece of wood, but anything
too close to the blade would set it off.

It's another method, but not something I think would really work.
There's just too much information to process to prevent false trips and
ensure real ones. Anyone ever played with the Xbox Kinect?
