1. An apparatus comprising:
- a controller configured to output control signals;
a first actuator configured to oscillate for a first period of time upon receiving a first control signal from the controller to produce a first inertial force in a first direction; and
a second actuator configured to oscillate for a second period of time upon receiving a second control signal from the controller to produce a second inertial force in a second direction, wherein actuation of the first and second actuators is coordinated by the controller such that the first and second actuators together output a total inertial force in a desired direction as a result of the first and second inertial forces,wherein the first and second actuators are coordinated by maintaining a constant phase difference between the first actuator and the second actuator.

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.
