REVIEW ON HAND GESTURE RECOGNITION TECHNIQUES FOR HUMAN-COMPUTER INTERACTION

Abstract

The gestural equivalent of direct manipulation interfaces are those which use gesture alone. These can range from interfaces that recognize a few symbolic gestures to those that implement fully fledged sign language interpretation. Similarly interfaces may recognize static hand poses, or dynamic hand motion, or a combination of both. In all cases each gesture has an unambiguous semantic meaning associated with it that can be used in the interface. In this section a brief review on the technology used to capture gesture input is presented. Finally we summarize the lessons learned from these interfaces.
