Gestures in Python

[Brian Kelley]

Back in the day I did gesture recognition using a floating vector 
strokes and a neural network for classification.

Essentially you trap strokes and put them into a vector like:

[(angle, distance), (angle, distance) ...]

new strokes come in the end and disappear off of the beginning.

We then trained the neural network on various gestures like circles, 
stars etc.

If a gesture was recognized, the floating window of strokes was cleared 
and sat waiting for a new gesture.

The nice thing is that the classification was only taking 3-5% cpu on a 
pentium 200 so we had plenty of time do do other stuff.
