Directional inertial tactile feedback using rotating masses
First Claim
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.

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.
