AUTONOMOUS CAMERA BASED EYE CONTROLLED WHEEL CHAIR USING RASPBERRY-PI

A novel technique is implemented for the eye controlled based independent and cost effective system. The purpose of Eye movement based control electronic wheelchair is to eliminate the necessity of the assistance required for the disabled person. And it provides great opportunity of the disabled to feel of independent accessible life. The implemented system will allow the disabled person to control the wheelchair without the assistance from other persons. In this system controlling of wheelchair carried out based on Eye movements. The camera is mounted in front of the user, to capture the image of any one of the Eye (either left or right) and tracks the position of eye pupil with the use of Image processing techniques. According to the position of the eye, wheelchair motor will be directed to move left, right and forward. In addition to this, for the safety purpose infrared obstacle sensor is mounted in front of wheelchair to detect the obstacles and automatically stop the wheelchair movement. An APR module is mounted in wheel chair which gives information about the obstacle through speaker. To make system cost effective for monitoring, a Raspberry pi board allowed to access the system without displaying unit
