A basic hand gesture control system for PC applications

We discuss the issues involved in controlling computer applications 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 examine which gestures are appropriate, how the gestures can be recognized, and which commands the gestures should control. The tracking method is detailed, along with its use in providing coordinates for the gesture control a PowerPoint presentation
