Abstract
A method and apparatus for wheelchair control. The position and distance of a touch point on a touch pad is used to set speed and wheel differential control. The two major wheels of the wheelchair are controlled according to these set quantities. Exceeding either of two horizontal accelerations measured by an accelerometer limits the set speed. Wheelchair control is shut down upon exceeding a vertical acceleration limit.
