A primary goal of gesture recognition research is to create a system which can identify specific human gestures and use them to convey information or for device control. Interface with computers using gestures of the human body, typically hand movements. In gesture recognition technology, a camera reads the movements of the human body and communicates the data to a computer that uses the gestures as input to control devices or applications. For example, a person clapping his hands together in front of a camera can produce the sound of cymbals being crashed together when the gesture is fed through a computer.?
In everyday life, physical gestures are a powerful means of communication. A set of physical gestures may constitute an entire language, as in sign languages. They can economically convey a rich set of facts and feelings. For example, waving one's hand from side to side can mean anything from a "happy goodbye" to "caution". Use of the full potential of physical gesture is also something that most human computer dialogues lack.
The need for more "natural" interaction techniques has been often stressed. This seminar makes the modest suggestion that gesture-based input is such a technique. Research Into the uses of gesture in human computer interaction is embryonic, and we hope to have inspired others to exercise their ingenuity in developing effective gestures.
