Abstract
A force module and a haptic device configured to prevent the vibration property from being diminished are offered. The force module according to one aspect includes a force sensation creating device configured to create a kinesthetic illusion through asymmetric vibration; and a supporting portion arranged between the force sensation creating device and a target portion to which the force sensation creating device is attached, and configured to support the force sensation creating device with respect to the target portion in such a manner as to allow for vibration.
Claims13
A force module comprising:
- a force sensation creating device configured to create a kinesthetic illusion through asymmetric vibration;
- and
- a supporting portion arranged between the force sensation creating device and a target portion to which the force sensation creating device is attached, the supporting portion being configured to support the force sensation creating device with respect to the target portion in such a manner as to allow for vibration,
- wherein the force sensation creating device is configured to generate asymmetric vibration in such a manner as to provide a being-pulled sensation in a predetermined guiding direction,
- the target portion is an operation member manually manipulated by a user,
- the guiding direction of the force sensation creating device is established along a manipulation direction of the target portion,
- the target portion is a steering wheel that is rotationally manipulated, and
- the force sensation creating device is arranged on an upper side of the steering wheel with respect to a rotational shaft of the steering wheel.
