AUTOMATIC CAMERA BASED EYE CONTROLLED WHEELCHAIR SYSTEM USING RASPBERRY PI

Abstract

This method includes the electronic wheelchair that implemented for the disabled person. The purpose of this eye controlled wheelchair is to eliminate the assistance required for the disabled person. In this system controlling of wheelchair is depend on eye movements and central switch. Camera is mounted on wheelchair in front of the person, for capture the image of eye and tracks the position of eye pupil by using some image processing techniques. According to eye pupil position of user, motor will be move in required direction such as left, right and forward. Ultrasonic sensor is mounted in front of wheelchair for safety to detect static or mobile barriers and stop the wheelchair movement automatically. A central switch is also mounted on wheelchair for emergency purpose and stop to move in require direction if any one call to stop and someone require attention on themselves. This is independent and cost effective wheelchair system. A raspberry pi board is used to control whole system.
