Abstract

A system for controlling a sound wave-based touch recognition interface includes: an auditory user interface (AUI) pad configured to transfer a sound wave, a sound wave recognition member configured to convert the sound wave transferred from the AUI pad into an electrical signal, and an actuator member attached to one side of the AUI pad and configured to be deformed in response to the electrical signal converted by the sound wave recognition member.

Claims

1. A system for controlling a sound wave-based touch recognition interface, comprising:

an auditory user interface (AUI) pad configured to transfer a sound wave;

a sound wave recognition member configured to convert the sound wave transferred from the AUI pad into an electrical signal; and

an actuator member attached to one side of the AUI pad and being deformable in response to the electrical signal converted by the sound wave recognition member.

2. The system according to claim 1, further comprising:

a controller configured to receive the electrical signal from the sound wave recognition member to control the deformation of the actuator member.

3. The system according to claim 1, wherein the AUI pad is locally deformed.

4. The system according to claim 3, wherein the AUI pad is locally deformed along with the deformation of the actuator member.

5. The system according to claim 1, wherein when an external pressure is applied to the AUI pad, the AUI pad is locally deformed by the external pressure, and the actuator member is deformed by the external pressure.

6. The system according to claim 1, wherein when an external pressure is applied to the AUI pad, the AUI pad is locally deformed by the external pressure, and the actuator member is not deformed by the external pressure.

7. The system according to claim 1, wherein the actuator member is one of a plurality of actuator members, and only some of the plurality of actuator members are operated.

8. The system according to claim 1, wherein the actuator member is one of a plurality of actuator members, and all of the plurality of actuator members are operated.

9. The system according to claim 1, wherein one or more vibration characteristics of the AUI pad are changed based on when the actuator member is not deformed, when the actuator member is substantially completely deformed, or when the actuator member is partially deformed.

10. The system according to claim 9, wherein:

when the actuator member is not deformed, the actuator member is flat,

when the actuator member is substantially completely deformed, both ends of the actuator member are warped, and

when the actuator member is partially deformed, only one end of the actuator member is deformed.

11. The system according to claim 1, wherein the system for controlling the sound wave-based touch recognition interface is applied to an interface of a vehicle.

12. The system according to claim 1, wherein an operation of the actuator member stops to change one or more vibration characteristics of the AUI pad.
