Abstract
One embodiment of the present invention provides a haptic device including a flexible and deformable tube, a liquid or gel-like substance, a sensor and an actuator. The flexible and deformable tube is affixed to a grip area to be gripped by a user. The liquid or gel-like substance is sealed within the tube and configured to transmit a pressure or/and pressure vibration vibration/pressure therethrough. The sensor is configured to detect the pressure or/and pressure vibration vibration/pressure generated in the tube. The actuator is configured to generate a haptic signal in the tube and/or the substance so as to be transmitted to the user.
Claims27
A haptic device to be mounted on a grip area to be gripped by a user, the haptic device comprising:
- a flexible and deformable tube affixed to the grip area;
- a liquid or gel-like substance sealed within the tube and configured to transmit a pressure or/and pressure vibration therethrough;
- and
- a sensor configured to detect the pressure or/and pressure vibration generated in the tube;
- an actuator configured to generate a haptic signal in the tube and/or the substance so as to be transmitted to the user.
A haptic covering for a steering wheel, comprising:
- a flexible and deformable toroidal tube affixed to a rim of the steering wheel;
- two self-sensing transducers provided in the toroidal tube, configured to detect the pressure or/and pressure vibration within a given frequency range and a given magnitude range, and configured to generate the pressure or/and pressure vibration as a haptic signal;
- a processor unit configured to receive a detection result from the self-sensing transducers, configured to control the self-sensing transducers to generate the haptic signal based on the received detection result, and configured to communicate with an in-car central processing unit.
