Summary
Wiimote. Acceleration data. Quantize the (x,y,z) acceleration data using k-means into a codebook of size 14. Plug the quantized data in to a left-right HMM. Segment gestures by making the user press and hold the A button during a gesture. They can recognize about 90% of all gestures accurately (circle, square, tennis swing).
Discussion
The point of this is.... what? Wii games, like Wii tennis and bowling, are pretty darned accurate at this already.
