A haptic mouse system, comprising a self-propelled mouse ( 102 ) and a mouse pad ( 100 ), is intended for use as a mouse pointing device in a computer system. The haptic mouse system can provide directional force feedback to a user in response to commands from the host computer. The self-propelled mouse ( 102 ) is moveable over the mouse pad ( 100 ) and is separable therefrom, thus allowing the user to operate the device in multiple strokes like a regular mouse. The self-propelled mouse ( 102 ) includes a control circuit and a two-dimensionally driving motor having multiple drive elements. The motor can interact with the mouse pad ( 100 ) and produce a horizontal propelling force ( 106 ), perceptible to the user as a haptic feedback, when the drive elements are activated in a predetermined pattern and only when the self-propelled mouse ( 102 ) is placed on the mouse pad ( 100 ). The control circuit responds to commands from the host computer by varying the activation pattern in order to control direction and magnitude of the propelling force ( 106 ). Several preferred embodiments describe two-dimensionally driving motors of various design and principle of operation, including planar and spherical dynamoelectric motors, friction drives, and different types of vibration motors.
