Abstract

A mobile terminal is allowed to automatically reproduce contents by a user-desired device based on its own position and orientation. A method for controlling contents reproduction in a mobile terminal includes acquiring at least one of position and orientation of the mobile terminal, selecting one of a plurality of external devices based on the acquired at least one of the position and the orientation, the plurality of external devices being capable of reproducing contents at different positions, respectively, and transmitting a signal to the selected one external device for controlling the selected one external device to reproduce the contents.

Claims

1. A method for controlling reproduction of content in a mobile terminal comprising:

controlling display of content on the mobile terminal or on a first display device among a plurality of display devices;

acquiring at least one of a position or an orientation of the mobile terminal;

selecting a second display device among the plurality of display devices based on the acquired at least one of the position or the orientation, the plurality of display devices being positioned at different locations relative to the mobile terminal and configured to display the content;

establishing a connection to the second display device; and

transmitting a signal to the selected second display device for controlling the second display device to display the content,

wherein the acquiring at least one of the position or the orientation of the mobile terminal includes

estimating a motion of the mobile terminal and analyzing a Received Signal Strength (RSS) data measured by at least one wireless access point, while a change in position of the mobile terminal is detected, and

acquiring an updated position of the mobile terminal based on the estimated motion of the mobile terminal and the analyzed RSS data when the change in position of the mobile terminal is no longer detected.

2. The method of claim 1, wherein the selecting the second device among the plurality of display devices includes selecting a display device that is positioned closest to the mobile terminal or a display device that is positioned corresponding to the orientation of the mobile terminal.

3. The method of claim 1, further comprising controlling the mobile terminal or the first display device to stop displaying the content and controlling the second display device to resume the content based on the signal.

4. The method of claim 1, further comprising controlling the mobile terminal or the first display device to continue displaying the content in response to a message from the second display device indicating a presence of another mobile terminal or a user accessing the content on the second display device.

5. The method of claim 1, wherein the transmitting the signal to the second display device includes

receiving an input for controlling the selected second display device to display the content, and

transmitting the signal for controlling the second display device to display the content according to the input.

6. The method of claim 1, wherein the acquiring at least one of the position or orientation of the mobile terminal includes

acquiring the RSS data from the at least one wireless access point, and

acquiring position information corresponding to RSS data having the most similar pattern to the pattern of the acquired RSS data from a database.

7. The method of claim 1, wherein the acquiring at least one of the position or orientation of the mobile terminal includes

determining a type of movement based on the detected change in position of the mobile terminal, the type of movement including standing, walking or running, and

estimating a position or orientation of the mobile terminal based on a duration of movement and a prescribed speed associated with the determined type of movement.

8. The method of claim 1, further comprising outputting an indicator that indicates that the second display device is displaying the content.

9. The method of claim 1, further comprising displaying a Graphic User Interface (GUI) on the mobile terminal to control playback of the content on the second display device.

10. A method for controlling an external device in a mobile terminal comprising:

acquiring at least one of a position or an orientation of the mobile terminal;

selecting at least one of a plurality of external devices based on the acquired at least one of the position or the orientation, the plurality of external devices being positioned at different locations and configured to receive a remote control signal from the mobile terminal;

establishing a connection to the selected at least one external device; and

transmitting the remote control signal to the selected at least one external device

wherein the selected at least one external device is determined such that the selected at least one external device is positioned closest to the mobile terminal or the selected at least one external device is positioned corresponding to the orientation of the mobile terminal.

11. The method of claim 10, further comprising displaying a Graphic User Interface (GUI) on the mobile terminal for controlling the selected at least one external device.

12. The method of claim 11, wherein the mobile terminal includes a plurality of GUIs that correspond to one or more of the plurality of external devices for providing a remote control interface at the mobile terminal.

13. The method of claim 11, further comprising loading a second GUI corresponding to at least one second external device located near the selected at least one external device.

14. The method of claim 13, further including

receiving an input to change the selected external device to the second external device, and

changing the selected external device to the second external device and displaying the second GUI that corresponds to the changed external device.

15. The method of claim 10, wherein the transmitting the remote control signal to the selected at least one external device includes

receiving an input for designating an external device among a plurality of selected external devices, and

transmitting the remote control signal to the designated external device.

16. The method of claim 10, wherein the selecting at least one of the plurality of external devices includes selecting two or more external devices from the plurality of external devices based on at least one of a plurality of positions or orientations acquired in a sequential manner when the at least one of the plurality of positions or orientations of the mobile terminal is acquired in the sequential manner.

17. The method of claim 10, further including receiving an input for setting a position of each of the plurality of external devices.

18. The method of claim 10, further including outputting an indicator that indicates that the selected at least one external device is under control of the mobile terminal.

19. A mobile terminal comprising:

a display;

a sensor to sense a position and orientation of the mobile terminal;

a controller configured to acquire at least one of a position or orientation of the mobile terminal relative to a plurality of external devices, and select at least one of the plurality of external devices based on the acquired at least one of the position or the orientation, the plurality of external devices being positioned at different locations and configured to receive a control signal from the mobile terminal; and

a communication device configured to transmit the control signal to the selected at least one external device,

wherein the control signal controls the selected external device to playback content transferred from another device or remotely controls a prescribed function of the selected at least one external device, and

wherein the selected at least one external device is determined such that the selected at least one external device is positioned closest to the mobile terminal or the selected at least one external device is positioned corresponding to the orientation of the mobile terminal.
