Abstract

Provided is an apparatus and method for controlling a portable terminal. The apparatus includes a contact sensing unit which senses an area of an external surface of the portable terminal contacted by a user as the user holds the portable terminal, a recognizing unit which recognizes a function mode of the portable terminal based on information about the contacted area sensed by the contact sensing unit, and a control unit which changes the portable terminal to a function mode recognized by the recognizing unit. Since a function mode of the portable terminal is controlled according to the way a user holds the portable terminal, convenience of changing a function mode of the portable terminal is provided through a single manipulation.

Claims

1. An electronic device, comprising:

a memory storing a plurality of recognition models;

a contact sensing unit to sense at least two areas contacted by a user and output contact signals corresponding to the contacted areas; and

at least one processor to identify a contact pattern of the contact signals, to recognize a mode based on the plurality of recognition models corresponding to the identified contact pattern, and to put the electronic device into the recognized mode, to determine if the recognized mode is a desired mode based on information input by the user, and, to update a corresponding recognition model stored in the memory based on a result of the determination.

2. The electronic device of claim 1, wherein the contact sensing unit comprises:

the at least two contact sensors which output the contact signals indicating whether the user contacts the contact sensors; and

a contact signal processor which combines the contact signals output from the contact sensors and generates information about the contact pattern.

3. The electronic device of claim 2, wherein the contact sensors are contact-type sensors that determine a contact has occurred when there is a direct contact by the user or contactless sensors that determine a contact has occurred when the user is within a predetermined distance of the contact sensors without directly contacting the contact sensors.

4. The electronic device of claim 1, further comprising a motion sensing unit which senses a rotation angle of the electronic device with respect to a predetermined reference axis that is preset in the electronic device or an angle of the predetermined reference axis with respect to the gravity direction as the user holds the electronic device, wherein the at least one processor additionally uses information sensed by the motion sensing unit to recognize the mode of the electronic device.

5. The electronic device of claim 4, wherein the motion sensing unit comprises an inertial sensor or an acceleration sensor to sense the motion of the electronic device.

6. The electronic device of claim 1, further comprising an external device sensing unit which senses attachment or detachment of an external device of the electronic device,

wherein the at least one processor additionally uses information sensed by the external device sensing unit as information for recognizing the mode of the electronic device.

7. The electronic device of claim 6, wherein the external device is any of an earphone, a headphone, secure digital (SD) card or multi media card (MMC).

8. The electronic device of claim 1, wherein the mode of the electronic device is any of SMS (Short Message Service) mode, MP3 mode, camera mode, left-hand call mode or right-hand call mode.

9. The electronic device of claim 1, wherein the contact pattern substantially covers at least one specific area on each side of the electronic device.

10. The electronic device of claim 1, wherein the contact sensing unit determines areas not contacted by the user when the user holds the electronic device.

11. The electronic device of claim 1, wherein the contact signals comprise identification information regarding each of specific and discrete areas of the electronic device contacted by the user.

12. The electronic device of claim 1, wherein the contact pattern comprises information about contact state of the contacted areas and contact state of at least one area not contacted by the user.

13. A method for controlling a electronic device, the method comprising:

storing a plurality of recognition models;

sensing at least two areas contacted by a user;

outputting contact signals corresponding to the contacted areas;

identifying a contact pattern of the contact signals;

recognizing a mode based on the plurality of recognition models corresponding to the identified contact pattern;

putting the electronic device into the recognized mode;

determining if the recognized mode is a desired mode based on information input by the user; and

updating a corresponding recognition model based on a result of the determination.

14. The method of claim 13, further comprising

combining the contact signals output from the at least two contact sensors;

and

generating information about the contact pattern.

15. The method of claim 14, wherein the at least two contact sensors are contact-type sensors that determine a contact has occurred when there is a direct contact by the user or contactless sensors that determine a contact has occurred when the user is within a predetermined distance of the contact sensors without directly contacting the contact sensors.

16. The method of claim 13, further comprising sensing a rotation angle of the electronic device with respect to a predetermined reference axis that is preset in the electronic device or an angle of the predetermined reference axis with respect to the gravity direction as the user holds the electronic device and additionally using the sensed angle to recognize the mode of the electronic device.

17. The method of claim 13, further comprising sensing attachment or detachment of an external device of the electronic device and additionally using the sensed attachment or detachment to recognize the mode of the electronic device.

18. The method of claim 17, wherein the external device is any of an earphone, a headphone, secure digital (SD) card or multi media card (MMC).

19. The method of claim 13, wherein the mode of the electronic device is any of SMS (Short Message Service) mode, MP3 mode, camera mode, left-hand call mode or right-hand call mode.

20. The method of claim 13, wherein the contact pattern substantially covers at least one specific area exists on each side of the electronic device.

21. The method of claim 13, further comprises determining areas not contacted by the user when the user holds the electronic device.
