Abstract

An operating mode control apparatus and method for a mobile terminal are disclosed. The apparatus and method enable the user to control the operation of a mobile terminal on the basis of the proximity of the user to the mobile terminal, the movement of the mobile terminal, and the housing orientation thereof. Hence, the user may enjoy a visuo-spatial user interface.

Claims

1. An operating mode control apparatus for a mobile terminal, comprising:

a sensor unit to sense a proximity of a user to the mobile terminal, to sense a housing orientation of the mobile terminal, and to output a sensing signal that indicates at least one of the proximity and the housing orientation;

a storage unit to store operating mode information of the mobile terminal corresponding to the sensing signal from the sensor unit; and

a control unit to receive the sensing signal and to control an operating mode of the mobile terminal on the basis of the operating mode information corresponding to the received sensing signal.

2. The operating mode control apparatus of claim 1, wherein the housing orientation is determined based on a side of the mobile terminal comprising a display unit.

3. The operating mode control apparatus of claim 1, wherein the sensor unit comprises at least one of:

a first sensor unit to sense contact between the user and the mobile terminal; and

a second sensor unit to sense the housing orientation of the mobile terminal.

4. The operating mode control apparatus of claim 3, wherein the second sensor unit is configured to sense the housing orientation of the mobile terminal after the first sensor unit senses no contact between the user and the mobile terminal.

5. The operating mode control apparatus of claim 3, wherein the sensor unit comprises a sensor to sense movement of the mobile terminal.

6. The operating mode control apparatus of claim 5, wherein the control unit comprises:

a sensing recognizer to determine the proximity of the user to the mobile terminal, and to identify the movement and the housing orientation of the mobile terminal, on the basis of the sensing signal from the sensor unit; and

an operation adjuster to control the operating mode of the mobile terminal according to a result produced by the sensing recognizer.

7. The operating mode control apparatus of claim 6, wherein the control unit controls the operation of at least one of a speaker, a microphone and a display unit of the mobile terminal.

8. The operating mode control apparatus of claim 7, wherein:

to transition between modes where a single speaker is present in the mobile terminal, the control unit adjusts the gain of the single speaker; and

,

to transition between modes where two or more speakers are present in the mobile terminal, the control unit alters a sound output path leading to the speakers.

9. An operating mode control method for a mobile terminal, comprising:

sensing a proximity of a user to the mobile terminal, and sensing a housing orientation of the mobile terminal; and

controlling an operating mode of the mobile terminal on the basis of a sensing signal and operating mode information corresponding to the sensing signal, the sensing signal indicating at least one of the proximity and the housing orientation.

10. The operating mode control method of claim 9, wherein the housing orientation is determined based on a side of the mobile terminal comprising a display unit.

11. The operating mode control method of claim 9, wherein sensing the housing orientation of the mobile terminal takes place after sensing that the user is not in proximity to the mobile terminal.

12. The operating mode control method of claim 9, further comprising sensing a movement of the mobile terminal.

13. The operating mode control method of claim 12, wherein controlling the operating mode comprises:

determining the proximity of the user to the mobile terminal;

identifying the movement or the housing orientation of the mobile terminal; and

controlling the operating mode of the mobile terminal according to the determination and identification results.

14. The operating mode control method of claim 13, wherein controlling the operating mode comprises controlling the operation of at least one of a speaker, a microphone and a display unit of the mobile terminal.

15. The operating mode control method of claim 14, wherein:

in controlling the operating mode to transition between modes, where a single speaker is present in the mobile terminal, the gain of the single speaker is adjusted; and

in controlling the operating mode to transition between modes, where two or more speakers are present in the mobile terminal, a sound output path leading to the speakers is altered.
