ABSTRACT:
Directional haptic feedback for a haptic feedback interface device. A haptic feedback interface device, in communication with a host computer, includes a housing physically contacted by a user operating the interface device, and a plurality of actuators producing inertial forces when the actuators are driven by control signals. Each of the actuators includes a rotatable eccentric mass positioned offset on a rotating shaft of the actuator, where the actuators are rotated simultaneously such that centrifugal forces from the rotation of masses combine to output the inertial forces substantially only along a single axis having a desired direction approximately in a plane of rotation of the masses.
