Abstract: Robots of the future should communicate with human in natural way. Hence, we are especially interested in hand motion based gesture interface. The purpose of this study was to present the reliable means of human-computer interfacing based on hand gestures made in three dimensions. In this paper we present a hand gesture recognition system which is of general use and can be used for different applications. The system is based on a MEMS accelerometer and it is able to recognize several gestures. The system can be divided in two parts: a gesture recognition module with MEMS sensor and a wheel-Chair controlled by the microcontroller.
Keywords: hand gesture recognition, micro-electromechanical systems (MEMS), gesture control, and wheel-chair.
