Active Handrest For Haptic Guidance and Ergonomic Support
First Claim
1. An active handrest system with haptic guidance, comprising:
- a haptic interface device operable to be manipulated by a user'"'"'s fingers, the haptic interface device being operatively connected to a movement sensing mechanism capable of sensing motion of the haptic interface device in three dimensions; and
an active handrest, operatively associated with the haptic interface device, the active handrest including an actuated support platform actuated in at least one degree of freedom, the active handrest being configured to support a hand, wrist, and/or arm of a user and being moveably responsive to motions of the haptic interface device detected by the movement sensing mechanism.

Abstract
An active handrest system (10, 10a) with haptic guidance comprises a haptic interface device (12) operable to be manipulated by a user'"'"'s fingers (14). The haptic interface device is operatively connected to a movement sensing mechanism (16) capable of sensing motion of the haptic interface device in three dimensions. An active handrest (18) is operatively associated with the haptic interface device, the active handrest including an actuated support platform (20) actuated in at least one degree of freedom. The active handrest is configured to support a hand, wrist, and/or arm of a user and is moveably responsive to motions of the haptic interface device detected by the movement sensing mechanism.

10. A method of providing haptic guidance and support during precision manipulation tasks, comprising:
-
supporting a hand, wrist or arm of a user on an actuatable support platform; generating position and/or force data relating to a haptic interface device and an active handrest during movement of a hand of a user; calculating a controlled compensation movement corresponding to an input movement control model based on the position signals and/or the force signals; and actuating the support platform to provide the controlled compensation movement. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of providing support to a wrist or arm during precision manipulation tasks, comprising:
-
supporting a hand, wrist, or arm of a user on an actuatable support platform; receiving signals from a haptic interface device during movement of a hand of a user; and moving the support platform in response to the signals received to provide support to the hand, wrist, or arm in a different location than an initial location of the actuatable support platform.
