Selection is made by tapping gently with the back of the head. For forward drive, three taps activate the switch. The user then tilts his head forward from the vertical position to produce forward motion. The speed attained is proportional to the degree of lateral head tilt. Turning can be accomplished with or without forward motion.
Motion is reduced to zero as the head is returned to the vertical position.
The user can then activate the head switch with one tap to return to the stop position. At the stop position, he is free to move his head without inducing wheelchair motion. Reverse drive is selected by two head taps, then, the same forward head tilt produces proportional rearward motion. The turn control in reverse is unchanged. You are visitor number .
