Abstract

In present-day scenario, many people aren’t able to control powered wheel chair using various interfaces like joystick, head control or voice control. For this reason, a new image-processing based mobility assistance system is proposed in this paper that automatically tracks the leg movement of the assisting person and follows him accordingly. In addition to this, an eye tracking feature has been inculcated into the proposed system that would help the disabled person in controlling the movement of wheel-chair using eye movement in the absence of an assisting person. The leg tracking module has been devised using the background subtraction and CamShift algorithms while the eye-tracking module utilizes the Haar cascades along with the Daugman’s algorithm to track the eye-movement.
