Abstract

A storage unit stores a correspondence between a voice command and a display mode modification operation. When a control unit determines that a vehicle is traveling according to a traveling state of the vehicle obtained by a traveling state acquisition unit, when a voice recognition unit recognizes a voice, which is uttered by a user and received by a voice input unit, and when the control unit determines that the recognized voice corresponds to a voice command stored in the storage unit, the control unit performs a display mode change operation corresponding to the voice command and modifies a display mode of an icon indicated on an indication screen of an indication unit.

Claims

1. An in-vehicle device configured to be equipped to a vehicle, the in-vehicle device comprising:

an indication unit having an indication screen and configured to indicate an icon corresponding to a gadget on the indication screen;

a traveling state acquisition unit configured to obtain a traveling state of the vehicle;

a voice input unit configured to receive a voice uttered by a user;

a voice recognition unit configured to recognize a voice uttered by a user and received by the voice input unit;

a storage unit configured to store a correspondence between a voice command and a display mode modification operation; and

a control unit configured to perform a display mode modification operation, which is stored in the storage unit and corresponding to a voice command to modify a display mode of an icon indicated on the indication screen when;

i) the control unit determines that the vehicle is traveling, according to a traveling state of the vehicle obtained by the traveling state acquisition unit,

ii) the voice recognition unit recognizes a voice, which is uttered by a user and received by the voice input unit; and

iii) the control unit determines that the recognized voice corresponds to the voice command stored in the storage unit.

2. The in-vehicle device according to claim 1, further comprising:

an operation receiving unit configured to receive an operation of a user as a display mode modification operation to modify a display mode of an icon,

wherein the control unit is configured to perform a display mode modification operation, which is stored in the storage unit and corresponding to a voice command to modify a display mode of an icon indicated on the indication screen when;

i) the control unit determines that the vehicle is traveling, according to a traveling state of the vehicle obtained by the traveling state acquisition unit;

ii) the control unit determines that the operation receiving unit receives a display mode modification operation;

iii) the voice recognition unit recognizes a voice, which is uttered by a user and received by the voice input unit; and

iv) the control unit determines that the recognized voice corresponds to the voice command stored in the storage unit.

3. The in-vehicle device according to claim 2,

wherein the operation receiving unit is configured to receive a gadget start operation performed by a user to start a gadget,

wherein the control unit is configured to perform a display mode modification operation, which is stored in the storage unit and corresponding to a voice command to modify a display mode of an icon indicated on the indication screen when:

i) the control unit determines that the vehicle is traveling, according to a traveling state of the vehicle obtained by the traveling state acquisition unit;

ii) the control unit determines that the operation receiving unit receives a display mode modification operation different from a gadget start operation;

iii) the voice recognition unit recognizes a voice, which is uttered by a user and received by the voice input unit; and

iv) the control unit determines that the recognized voice corresponds to the voice command stored in the storage unit.

4. The in-vehicle device according to claim 2,

wherein the operation receiving unit is configured to receive a display mode modification operation performed by a user to modify a display mode of an icon selected from icons by a user,

wherein the control unit is configured to perform a display mode modification operation, which is stored in the storage unit and corresponding to a voice command to modify a display mode of an icon selected by a user from icons indicated on the indication screen when:

i) the control unit determines that the vehicle is traveling, according to a traveling state of the vehicle obtained by a traveling state acquisition unit;

ii) the control unit determines that an operation receiving unit receives a display mode modification operation different from a gadget start operation;

iii) the voice recognition unit recognizes a voice, which is uttered by a user and received by the voice input unit; and

iv) the control unit determines that the recognized voice corresponds to the voice command stored in the storage unit.

5. The in-vehicle device according to claim 2, wherein the control unit is configured to enable the voice recognition unit to recognize a voice when the control unit determines that the operation receiving unit receives a display mode modification operation.

6. The in-vehicle device according to claim 1, wherein the control unit is configured to modify a display mode of an icon indicated on the indication screen by modifying a display position of an icon on the indication screen.

7. The in-vehicle device according to claim 1, wherein the control unit is configured to modify a display mode of an icon indicated on the indication screen by modifying a display size of an icon on the indication screen.

8. The in-vehicle device according to claim 1, wherein the control unit is configured to modify a display mode of an icon indicated on the indication screen by modifying a contrast of an icon on the indication screen.

9. The in-vehicle device according to claim 1, wherein the control unit is configured to modify a display mode of an icon indicated on the indication screen by modifying permission of indication of an icon corresponding to a gadget on the indication screen.

10. The in-vehicle device according to claim 1, wherein the gadget is a program configured to enable a user to access a frequently used software tool.

11. A method for modifying a display mode of an icon corresponding to a gadget indicated on an indication screen, the method comprising:

obtaining a traveling state of a vehicle;

receiving a voice uttered by a user using a voice input unit;

recognizing a voice received by the voice input unit using a voice recognition unit;

first determining whether the vehicle is traveling according to the obtained traveling state of the vehicle;

second determining whether the voice recognition unit recognizes a voice received by the voice input unit;

third determining whether the recognized voice corresponds to a voice command stored in a storage unit; and

performing a display mode modification operation, which is stored in the storage unit to correspond to the voice command, to modify a display mode of an icon indicated on the indication screen when all the first determining, the second determining, and the third determining make positive determinations.

12. The method according to claim 11, wherein the gadget is a program configured to enable a user to access a frequently used software tool.

13. A computer readable medium comprising instructions executed by a computer, the instructions including the method according to claim 11.
