Abstract
A force feedback mechanism designed for use with a mouse, trackball, keyboard, or other interface device manipulated by a user. The mechanism consists of a non-planar surface 11 that is substantially balanced with respect to a rotational axis 'A.' An actuator 12 controlled by a computer or microprocessor is connected to the non-planar surface 11. In response to signals from the computer or microprocessor the actuator 12 causes the non-planar surface 11 to rotate about its rotational axis 'A', thus conveying force feedback to the user's thumb or fingertip.
