In this paper, the authors present a new approach for communication with computer systems using hand gesture. The process is based on extracting features of the hand region and then using these features for communication with computer system. Their approach is defined in three steps segmentation for hand localization, feature extraction and feature identification to create a fuzzy rule base. The gesture is a natural way of communication for many people with sign language. In computer systems, gesture recognition is very difficult and complex task since the full recognition system should be able to identify the hand in different scales, positions, orientations, contrasts, funds, luminosity and others.
