Two pedals are used together to control a computer cursor. A Sensitivity Pedal (Pedal 2) varies the sensitivity (speed of movement) of the cursor and a Movement Pedal (Pedal 1 ) determines the direction of movement. By using both feet dynamically together, greater speed and precision is possible than with one foot alone. Cursor movements can be achieved which are both fast and precise, yet are still within the comfortable range of foot movement, by starting with maximum sensitivity then reducing the sensitivity as the target position is approached. Mouse-clicks are generated by rotational movement of the Sensitivity Pedal. Pedal movement may be sensed by electromagnetic induction, a linear voltage transducer, a potentiometer, or an optical transmission transducer. |
