This paper basically provides a real time model of a low cost wheel chair based on the guiding movement of the tongue, for the persons disabled with quadriplegia. The model is realized through the data comparison in serial communication with the special purpose microcontroller IC. In this paper tongue is our object detected by using infrared signals to serially interact with the controller, which in turn, controls the wheel chair movements. This communicative act with as the wireless, be here
