Issues of controlling public kiosks and other self service machines using gesture recognition

We discuss the issues involved in controlling self service machines via gestures composed of both static symbols and dynamic motions. Each gesture is modeled from either static model information or a linear-in-parameters dynamic system. Recognition occurs in a real-time environment using a small amount of processing time and memory. We will examine which gestures are appropriate, how the gestures can be recognized, and which commands the gestures should control
