  • Patent number: 7503852
    Abstract: A hand-held input device provides a directional force feedback that acts on a housing of the device. The input device includes a threaded shaft that is rotatably driven by an electric motor. The motor causes a mass to move in response to a control signal received from a host computing device, such as personal computer that is executing a game or simulation. When the mass is rapidly accelerated or abruptly stopped in response to the control signal, the change in momentum of the mass imparts a directional reactive force to the housing, and an operator holding the housing feels the haptic force.
