Gesture recognition using the XWand

Abstract: "The XWand is a wireless UI device that enables styles of natural interaction with intelligent environments. The XWand system exploits human intuition, allowing control of everyday objects through pointing and gesturing. We describe the hardware device and then examine several approaches to gesture recognition. We discuss results from experiments using a linear time warping method, a dynamic time warping (DTW) method, and a hidden Markov model-based method (HMM)."
