Abstract

An encased driving section includes magnets provided on a bottom surface in such a manner that their polarities are alternately oriented, a movable frame which is contained in the case and to which coils are attached, and an operating member fixed on the frame. When a state sensor unit senses a state of a vehicle or outside the vehicle, such as omission to turn off lights and the direction of wind, a control section determines whether or not the sensed state should be indicated to an operator and, when it determines that the information should be indicated, passes an electric current through the coils in a predetermined direction to drive the driving section in order to communicate the information to the operator through a haptic stimulus. The haptic interface device can communicate various information to the operator through their sense of touch.

Claims

1. A haptic interface device comprising:

state sensing means for sensing at least one of a state of a vehicle and a state outside the vehicle;

indication control means for determining whether or not information sensed by said state sensing means should be indicated to an operator and for generating haptic information representing said information when it determines that the information should be indicated to the operator; and

haptic experience presentation means for moving based on the haptic information provided from said indication control means.

2. The haptic interface device according to claim 1, wherein said haptic presentation means has two or more degrees of freedom of movement].

3. The haptic interface device according to claim 2, wherein said haptic experience presentation means comprises:

a base member;

an operating member to be operated by the operator;

a moving member movably attached to said base member and to which said operating member is fixed; and

operating member drive control means for driving said operating member in at least two degrees of freedom by moving said moving member drive; and

said operating member control means controls said moving member in a movement pattern according to information to be provided to the operator.

4. The haptic interface device according to claim 3, further comprising immobilization means for forcibly immobilizing said moving member when a condition which may require strong gripping of a steering wheel on which the haptic interface device is installed is detected.

5. The haptic interface device according to claim 4, wherein

said immobilization means has a lock mechanism for physically inhibiting a movable state of said moving member.

6. The haptic interface device according to claim 3, wherein

said operating member drive control means drives said operating member in a direction relating to information to be indicated to the operator as haptic information.

7. The haptic interface device according to claim 1, wherein

said state sensing means has an information receiving unit for receiving traffic information sent from a provider as a state outside the vehicle.
