Abstract

A mobile device having at least one microphone sensor and a method for controlling the same are disclosed. The method includes receiving at least two audio signals through the at least one microphone sensor within a predetermined time period, recognizing input directions and voice command from the at least two audio signals sequentially, determining whether the recognized input directions and voice command match to preset input directions and preset voice command mapped to the preset directions, sequentially for the at least two received audio signals, and executing a preset control command, if the recognized input directions and voice command match to the preset input directions and voice command.

Claims

1. A method for controlling a mobile device having at least one microphone sensor, the method comprising:

receiving at least two audio signals in a sequence through the at least one microphone sensor within a predetermined time period;

recognizing input directions and voice commands of the at least two audio signals in the sequence;

determining whether the recognized input directions and voice commands correspond with preset input directions and preset voice commands mapped to the preset directions; and

executing, by the mobile device, at least one preset control command, when the recognized input directions and voice commands are determined to correspond with the preset input directions and voice commands.

2. The method according to claim 1, wherein the executing step includes executing a control command for unlocking a screen of the mobile device or a control command for unlocking an application installed in the mobile device.

20. A computer-readable recording medium storing therein a computer program which is executable by a processor and implements the method of claim 1.

3. A method for controlling a mobile device having at least one microphone sensor, the method comprising:

receiving audio signals through the at least one microphone sensor;

selecting an audio signal among the received audio signals;

recognizing an input direction and voice command of the selected audio signal; and

identifying an object displayed in the recognized input direction of the selected audio signal, and

executing, by the mobile device, at least one control command based on the recognized voice command of the selected audio signal for the identified object.

4. The method according to claim 3, wherein the at least one control command corresponding to the recognized voice command includes at least one of a copy command, a delete command, an enlarge command, a contract command, a send command, and a share command for the identified object.

5. The method according to claim 3, wherein the executing step further includes executing a control command corresponding to the recognized voice command differently depending on the recognized input direction of the selected audio signal, even though the same voice command is recognized.

6. The method according to claim 3, wherein the selecting step includes selecting an audio signal having a highest sound pressure among the received audio signals by comparing the received audio signals.

21. A computer-readable recording medium storing therein a computer program which is executable by a processor and implements the method of claim 3.

7. A mobile device for process an input, the mobile device comprising:

a microphone unit including at least one microphone sensor configured to receive an audio signal; and

a controller configured to recognize an input direction and voice command of the received audio signal and to control the mobile device to execute at least one preset control command corresponding to the recognized input direction and voice command.

8. The mobile device according to claim 7, further comprising:

a memory configured to store direction-voice mapping information including information about input directions of audio signals and voice commands mapped to the input directions, and to store control commands corresponding to the direction-voice mapping information for controlling the mobile device.

9. The mobile device of claim 8, wherein the memory stores a mapping information list for at least two audio signals successively received within a predetermined time period and a control command corresponding to the mapping information list to control the mobile device.

10. The mobile device according to claim 9, wherein when an order and content of direction-voice mapping information recognized from the at least two audio signals match with the mapping information list stored in the memory, the controller controls execution of the control command corresponding to the mapping information list.

11. The mobile device according to claim 10, wherein the control command corresponding to the mapping information list includes a command for unlocking a screen of the mobile device or a command for unlocking an application installed in the mobile device.

12. The mobile device according to claim 7, wherein the controller identifies an object displayed in the recognized input direction of the audio signal, and controls execution of a control command corresponding to the recognized voice command for the identified object.

13. The mobile device according to claim 12, wherein the control command corresponding to the recognized voice command includes at least one of a copy command, a delete command, an enlarge command, a contract command, a send command, and a share command for the identified object.

14. The mobile device according to claim 7, wherein the controller controls execution of a control command corresponding to the recognized voice command differently depending on the recognized input direction of the audio signal, even though the same voice command is recognized.

15. The mobile device according to claim 14, wherein when the control command corresponding to the recognized voice command is a search command, the controller controls execution of the search command by using a different search engine or by displaying a different category of search results depending on the recognized input direction of the audio signal.

16. The mobile device according to claim 14, wherein when the control command corresponding to the recognized voice command is a communication connection command, the controller controls execution of the communication connection command by using a different communication target or a different communication scheme depending on the recognized input direction of the audio signal.

17. The mobile device according to claim 14, wherein when the control command corresponding to the recognized voice command is an execution command, the controller controls execution of the execution command by using at least one of a different execution target, a different execution unit, and a different category of execution results depending on the recognized input direction of the audio signal.

18. The mobile device according to claim 14, wherein when the control command corresponding to the recognized voice command is an electronic mail execution command, the controller selectively controls execution of either a first account'"'"'s electronic mail or a second account'"'"'s electronic mail depending on the recognized input direction of the audio signal.

19. The mobile device according to claim 14, wherein when the control command corresponding to the recognized voice command is a voice execution command, the controller selectively controls output of a result of executing the voice execution command either in a first category including text or a second category including voice, depending on the recognized input direction of the audio signal.
