  • Publication number: 20120293312
    Abstract: The invention is to provide a force feedback device and a positioning method. The force feedback device includes a microprocessor which controls a motor to rotate at a constant velocity. The motor moves a non-equidistant blocking grating to passes through a detector. The detector detects the passage of the blocking grating to generate an on or off signal. A timer counts the time of the on or off signal to calculate the angle which the blocking grating passes through. The absolute angle of the blocking grating is decided by comparing with an absolute angle stored in a memory to position a joystick.
