1. A haptic feedback interface device in communication with a host computer, said interface device outputting directional inertial sensations to a user based on interactions and events occurring in a graphical environment displayed by said host computer, the interface device comprising:

  • a housing physically contacted by a user operating said interface device; and

    a plurality of actuators producing inertial forces when said actuators are driven by control signals, each of said actuators including an eccentric mass positioned offset on a rotating shaft of said actuator, wherein said mass can be rotated by said actuator, and wherein said plurality of actuators are rotated simultaneously such that centrifugal forces from said rotation of said masses combine to output said inertial forces substantially only along a single axis having a desired direction approximately in a plane of rotation of said eccentric masses.
