We present results on the recognition of intentional humangestures for video annotation and retrieval. We definea gesture as a particular, repeatable, human movementhaving a predefined meaning. An obvious application ofthe work is in sports video annotation where umpire gesturesindicate specific events. Our approach is to augmentvideo with data obtained from accelerometers worn as wristbands by one or more officials. We present the recognitionperformance using a Hidden Markov Model approach forgesture modeling with both isolated gestures and gesturessegmented from a stream.
