HAND GESTURE RECOGNITION USING ACCELEROMETER FOR DISABLED

Only way of communication for the Disabled persons who can‟t speak and hear is the sign language. A system has been proposed in this paper which helps in recognizing the Gestures made by disabled persons and thus helps them to communicate with others easily using the Gesture Technology. Portable device is developed in this system for making Gestures. This device contains tri-axial accelerometer motion sensor, microcontroller (msp430G Launchpad) and wireless Technology (Bluetooth). Microcontroller reads the 3-axis data of the sensor and sends wirelessly through Bluetooth to the processor when the user makes the Gesture. An Application has been developed on the processor, which will process the data and message will be displayed that the user wants to convey based on the recognized gesture. The system uses very low power of 3.35v.
