Abstract
This paper basically provides a real time model of a low cost wheel chair based on the guiding movement of the retina, for the persons disabled with quadriplegia. This model is expected to benefit the poor paralyzed people as it provides a simplified low cost model of the wheel chair. The model is realized through matlab in serial communication with the special purpose microcontroller IC manufactured by Atmel Corporation, namely as ATmega1284P-IC. The eye movement is detected by a camera, which in reality is captured by a signal called electrooculographic (EOG) signal. The EOG signals are processed so that they can guide the serially interfaced microcontroller, which in turn, controls the wheel chair movements. The serial communication between matlab script and the microcontroller is carried out through RS-232 port. An LCD may be placed on the board to display the actions made in accordance with the retina movement.
