Abstract

A mobile terminal including a wireless communication unit configured to provide wireless communication; a display unit; a sensing unit configured to sense a plurality of taps applied to the display unit; and a controller configured to control the display unit to be in a deactivated state, receive a plurality of taps applied to the display unit in the deactivated state, and execute a voice recognition function while maintaining the display unit in the deactivated state, when a pattern formed by the plurality of taps matches a preset pattern.

Claims

1. A mobile terminal comprising:

a wireless communication unit configured to provide wireless communication;

a display unit;

a sensing unit configured to sense a plurality of taps applied to the display unit; and

a controller configured to;

control the display unit to be in a deactivated state,

receive a plurality of taps applied to the display unit in the deactivated state,

execute a voice recognition function while maintaining the display unit in the deactivated state, when a pattern formed by the plurality of taps matches a preset pattern,

receive a voice input together with the plurality of taps, and

execute a function corresponding to the received voice input based on a finally applied tap among the plurality of taps being maintained,

wherein the voice input is received before the finally applied tap.

2. The mobile terminal of claim 1, wherein the controller is further configured to execute the voice recognition function when the finally applied tap among the plurality of taps is maintained.

3. The mobile terminal of claim 2, wherein the controller is further configured to terminate the voice recognition function when the finally applied tap is released.

4. The mobile terminal of claim 3, wherein the controller is further configured to terminate the voice recognition function when the finally applied tap is no longer sensed and a preset period of time has lapsed.

5. The mobile terminal of claim 2, wherein the controller is further configured to:

receive a voice input while the voice recognition function is executed, and

activate at least a portion of the display unit and display screen information of a corresponding function designated by the voice input.

6. The mobile terminal of claim 5, wherein when the corresponding function corresponds to one function, the controller displays the screen information for the corresponding one function, and when the corresponding function corresponds to at least two functions, the controller displays graphic objects respectively corresponding to the at least two functions on the display unit.

7. The mobile terminal of claim 1, wherein the controller is further configured to output notification information indicating the execution of the voice recognition function including at least any one among a visual method, an acoustic method, and a tactile method.

8. The mobile terminal of claim 2, wherein the controller is further configured to output notification information indicating the voice recognition is available when the finally applied tap is released and a voice input is not received.

9. The mobile terminal of claim 1, wherein the controller is further configured to receive a user selection as to whether the function corresponding to the received voice input is to be executed.

10. The mobile terminal of claim 9, wherein when the pattern formed by the plurality of taps is not identical to the pre-set pattern, the controller is further configured not to execute the function corresponding to the received voice input.

11. The mobile terminal of claim 1, further comprising:

at least first and second speakers having different output sound paths,

wherein the controller is further configured to;

output a sound related to the voice recognition function using the first speaker when a user is a first predetermined distance from the mobile terminal, and

output the sound related to the voice recognition function using the second speaker when the user is a second predetermined distance from the mobile terminal greater than the first predetermined distance.

12. The mobile terminal of claim 11, wherein an output amplitude of the sound output from the first speaker is smaller than that of the second speaker.

13. A method of controlling a mobile terminal, the method comprising:

controlling, via a controller of the mobile terminal, a display unit to be in a deactivated state;

receiving a plurality of taps applied to the display unit in the deactivated state;

executing, via the controller, a voice recognition function while maintaining the display unit in the deactivated state, when a pattern formed by the plurality of taps matches a preset pattern;

receiving a voice input together with the plurality of taps; and

executing a function corresponding to the received voice input based on a finally applied tap among the plurality of taps being maintained,

wherein the voice input is received before the finally applied tap.

14. The method of claim 13, further comprising:

executing the voice recognition function when the finally applied tap among the plurality of taps is maintained.

15. The method of claim 14, further comprising:

terminating the voice recognition function when the finally applied tap is released.

16. The method of claim 15, further comprising:

terminating the voice recognition function when the finally applied tap is no longer sensed and a preset period of time has lapsed.

17. The method of claim 14, further comprising:

receiving a voice input while the voice recognition function is executed; and

activating at least a portion of the display unit and display screen information of a corresponding function designated by the voice input.

18. The method of claim 17, wherein when the corresponding function corresponds to one function, the method further comprises displaying the screen information for the corresponding one function, and when the corresponding function corresponds to at least two functions, the method further comprises displaying graphic objects respectively corresponding to the at least two functions on the display unit.
