The beliefs states are probability density functions conditioned on the trajectories of the observed variables. We describe example implementations of gesture recognition based on Hidden Markov Models and a dynamic programming recognition algorithm. Granular synthesis is used to present the audio display of the changing probabilities and observed states.</ABSTRACT><NOTES>DCS Technical Report TR-2002-127</NOTES></RECORD></RECORDS></XML>
