Abstract: Wheelchairs are used by physically disabled people. Now a days technology promises a wide scope in developing smart wheelchair. This paper is to describe a smart wheelchair using smart phone to control the rotation of wheel chair based upon the body gesture and voice of the physically challenged people. In build voice and gesture are used to control the movements of wheelchair as well as by using smart phone. 8 sensors are used among which 2 of them are IR sensors the remaining 6 are for temperature, smoke detection, light detection sensors. This system that allows the user to effectively interact with the wheelchair at various levels of the control and sensing. The system is divided into 3 main units Gesture recognition through Android, Voice recognition through Android, Motor control by signal conditioning. The system is based on grouping an android phone with a Sensors and AVR micro-controllers.
