Abstract:
A method and apparatus for adjusting force output from force feedback devices based on user contact with the device. A degree of user contact with a manipulandum of the device is determined by examining the motion of the manipulandum in at least one degree of freedom. A force is output in the degree of freedom of the manipulandum by an actuator of the force feedback device, where a magnitude of the force is adjusted in accordance with the degree of user contact. The force output can be stopped if the user is not contacting the manipulandum, or the forces can be reduced in magnitude if the user has a light contact or reduced grip on the manipulandum. The device can also continue to monitor manipulandum motion to determine when the user is again interacting with the manipulandum and to reapply or increase the magnitude of the forces.
