Abstract

The present invention relates to a mobile terminal enabling a user to more conveniently use the terminal and a method of controlling therefor. According to at least one of embodiments of the present invention, a voice data can be recorded using an attachable/detachable stylus pen and the recorded voice data can be easily stored and managed by the stylus pen. And, according to at least one of embodiments of the present invention, a virtual hand writing memo written by the attachable/detachable stylus pen can be easily stored and managed by the stylus pen.

Claims

1. A mobile terminal, comprising:

a detachable stylus pen including a microphone;

a touch screen configured to output an execution screen of an application;

a wireless communication unit configured to receive a voice signal from the detached stylus pen, the voice signal generated in response to at least one voice received via the microphone while the stylus pen is detached from the mobile terminal; and

a controller configured to;

execute the application; and

control the touch screen to display text corresponding to at least a portion of the received voice signal at a specific position of the execution screen in response to selection of the specific position by the stylus pen.

2. The mobile terminal of claim 1, further comprising a memory, wherein the controller is further configured to:

store the received voice signal in the memory; and

cause the touch screen to display a playback icon for allowing playback of the stored voice signal when the playback icon is selected.

3. The mobile terminal of claim 1, wherein:

the at least one voice comprises voices of a plurality of persons; and

the controller is further configured to cause the touch screen to display a plurality of texts, each text corresponding to a respective one of the voices of the plurality of the persons.

4. The mobile terminal of claim 1, wherein the controller is further configured to cause the touch screen to output a list of candidate words for replacing a word of the displayed text in response to selection of the word.

5. The mobile terminal of claim 4, wherein the candidate words are arranged in a specific order according to their degrees of similarity to a signal section of the voice signal corresponding to the word.

6. The mobile terminal of claim 1, wherein:

the stylus pen further includes a memory configured to store the voice signal, the at least one voice comprising a plurality of voice data; and

the controller is further configured to cause the touch screen to output a pop-up window including a plurality of texts, each text corresponding to a respective one of the plurality of voice data, such that one of the plurality of texts is selected via the pop-up window.

7. The mobile terminal of claim 6, wherein the controller is further configured to cause the touch screen to display recommended text among the plurality of texts distinctively over the rest of the plurality of texts, the text in the pop-up window recommended based on the specific position.

8. A method of controlling a mobile terminal comprising a detachable stylus pen including a microphone, a touch screen, and a wireless communication unit, the method comprising:

outputting an execution screen of an application via the touch screen;

receiving a voice signal from the detached stylus pen via the wireless communication unit, the voice signal generated in response to at least one voice received via the microphone while the stylus pen is detached from the mobile terminal; and

displaying text corresponding to at least a portion of the received voice signal at a specific position of the execution screen in response to selection of the specific position by the stylus pen.

9. The method of claim 8, wherein the mobile terminal further comprises a memory and the method further comprises:

storing the received voice signal in the memory; and

displaying a playback icon for allowing playback of the stored voice signal when the playback icon is selected from the touch screen.

10. The method of claim 8, wherein:

the at least one voice comprises voices of a plurality of persons; and

the method further comprises displaying a plurality of texts, each text corresponding to a respective one of the voices of the plurality of the persons.

11. The method of claim 8, further comprising outputting a list of candidate words for replacing a word of the displayed text in response to selection of the word.

12. The method of claim 11, wherein the candidate words are arranged in a specific order according to their degrees of similarity to a signal section of the voice signal corresponding to the word.

13. The method of claim 8, wherein:

the stylus pen comprises a memory configured to store the voice signal, the at least one voice comprising a plurality of voice data; and

the method further comprises outputting a pop-up window including a plurality of texts, each text corresponding to a respective one of the plurality of voice data, such that one of the plurality of texts is selected via the pop-up window.

14. The method of claim 13, further comprising displaying recommended text among the plurality of texts distinctively over the rest of the plurality of texts, the text in the pop-up window recommended based on the specific position.

15. A mobile terminal, comprising:

a detachable stylus pen including a tracking sensor configured to track virtual hand writing;

a wireless communication unit configured to communicate with the detached stylus pen and to communicate with a counterpart to perform a phone call;

a memory configured to store information; and

a controller configured to cause the memory to store a virtual hand writing memo via an application in response to tracking, by the tracking sensor, of the virtual hand writing memo during the phone call.

16. The mobile terminal of claim 15, wherein the controller is further configured to cause the memory to store information about the counterpart together with the virtual hand writing memo such that a call can be made to the counterpart via the stored information while the stored virtual hand writing memo is accessed.

17. The mobile terminal of claim 15, wherein:

the tracking sensor is further configured to track a drawing pattern following the virtual hand writing memo, the drawing pattern corresponding to one of a plurality of drawing patterns pre-stored in the memory; and

the controller is further configured to identify the application according to the drawing pattern.

18. A method of controlling a mobile terminal comprising a detachable stylus pen including a tracking sensor, a memory, and a wireless communication unit, the method comprising:

communicating with a counterpart via the wireless communication unit to perform a phone call; and

storing a virtual hand writing memo in the memory via an application in response to tracking, by the tracking sensor, of the virtual hand writing memo during the phone call.

19. The method of claim 18, further comprising storing, in the memory, information about the counterpart together with the virtual hand writing memo such that a call can be made to the counterpart via the stored information while the stored virtual hand writing memo is accessed.

20. The method of claim 18, further comprising:

tracking, by the tracking sensor, a drawing pattern following the virtual hand writing memo, the drawing pattern corresponding to one of a plurality of drawing patterns pre-stored in the memory; and

identifying the application according to the drawing pattern.
