Gesture Recognition with a Wii Controller
Scholmer et al recognize gestures using the accelerometer data of the Wiimote. First the data is vector quantized with k-means and k=14. Next the data is input to HMMs for each of 5 gestures. Additionally the accelerometer data is filtered before processing. Acceleration values below a threshold are considered idle and ignored as well as accelerations that differ too greatly on all components from the previous acceleration.
Discussion
Wii+HMM=Gestures. Also all but one of the gestures are in only a 2D plane which should make classification of the other relatively simple.
