Abstract

A force sensation exhibiting device has a housing which can be grasped by a hand, at least one rotatably or linearly movable motor contained in the housing, an input section where repulsive force information are input, and control circuit for driving and controlling said motor according to the repulsive force information, wherein a force sensation is given to said hand by a drive of the motor.

Claims

1. A force sensation exhibiting device comprising

a housing which can be grasped by a hand,

at least one rotatably or linearly movable motor contained in the housing,

an input section where repulsive force information are input, and

control means for driving and controlling said motor according to the repulsive force information, wherein

a force sensation is given to said hand by a drive of said motor.

2. A force sensation exhibiting device according to claim 1., wherein

a motor corresponding to a force vector is intermittently driven in a direction reverse to a force vector of the force sensation to be exhibited.

3. A force sensation exhibiting device according to claim 2, wherein

a motor corresponding to a force vector is intermittently driven so that a torque is proportional to a magnitude of said vector, and

in the intermittently driving, a period of turning off the motor is longer than a period until said activated motor stops.

4. A force sensation exhibiting device according to claim 2, wherein

activating motion, moving in the reverse direction, and stopping motions are repeated, in which

a motor corresponding to a force vector is activated so that a torque is proportional to a magnitude of said vector, and after being moved in a certain distance or a certain angle, activated in an extremely low torque in a direction reverse to that of the former activation, and after returns to a position or an angle before said activation is initiated, said motor is stopped.
