Abstract

Provided is a multimedia device that has a detachable controller. The detachable controller may attach to a main body of a multimedia device and act as a control panel of the main body. Further, the controller may be detached from the main body of multimedia device and act as a remote controller of the multimedia device.

Claims

1. A multimedia device comprising:

a main body configured to process input data and to output multimedia data; and

a controller configured to control a function of the main body,

wherein the main body and the controller each comprise one or more joints for attaching and detaching the controller to and from the main body, and the controller is configured to function as a control panel of the main body while attached to the main body and to function as a remote control of the main body while detached from the main body.

2. The multimedia device of claim 1, wherein each of the joints comprises magnets for attaching the main body and the controller to each other by a magnetic force therebetween.

3. The multimedia device of claim 1, wherein at least one of the main body and the controller comprises a first sensor unit configured to detect an attached and detached state of the controller, and

the controller comprises:

an input unit configured to display at least two user interface modes; and

a controlling unit configured to change a user interface mode of the input unit according to the attached or detached state of the controller detected by the first sensor unit.

4. The multimedia device of claim 3, wherein the input unit comprises a touch screen panel,

the controlling unit is configured to display a first user interface input window on the touch screen panel in response to the first sensor unit detecting that the controller is attached to the main body and to display a second user interface input window on the touch screen panel in response to the first sensor unit detecting that the controller is detached from the main body, and

the first user interface input window and the second user interface input window are different from each other.

5. The multimedia device of claim 1, wherein the controller further comprises a second sensor unit configured to detect how a user is holding the controller, and

the controlling unit configured to change a user interface mode of the input unit based on how the user is holding the controller.

6. The multimedia device of claim 5, wherein the input unit comprises a touch screen panel,

the controlling unit is configured to display a third user interface input window on the touch screen panel in response to the second sensor unit detecting that the user is holding the controller with both hands and to display a fourth user interface input window on the touch screen panel in response to the second sensor unit detecting that the user is holding the controller with one hand, and

the third user interface input window and the fourth user interface input window are different from each other.

7. The multimedia device of claim 1, wherein the controller further comprises a third sensor unit configured to detect a direction of the controller, and

the controlling unit is configured to change a user interface mode of the input unit based on the direction of the controller.

8. The multimedia device of claim 1, wherein the main body and the controller comprise a first connector and a second connector, respectively, for electrically connecting to each other while the controller is attached to the main body.

9. The multimedia device of claim 8, wherein a control signal of the controller is transmitted through the first connector and the second connector while the controller is attached to the main body.

10. The multimedia device of claim 8, wherein the controller is charged through the first connector and the second connector while the controller is attached to the main body.

11. A method of controlling a multimedia device having a detachable controller that attaches to at least a portion of a front surface of a main body, the method comprising:

functioning as a control panel of the main body of the multimedia device while the controller is attached to the main body; and

functioning as a remote control of the main body of the multimedia device while the controller is detached from the main body.

12. The method of claim 11, further comprising:

detecting an attached or detached state of the controller to or from the main body; and

changing a user interface mode of the controller based on the attached or detached state of the controller.

13. The method of claim 12, wherein the controller comprises a touch screen panel, and

the changing of a user interface mode of the controller comprises changing a user interface input window on the touch screen panel.

14. The method of claim 11, further comprising:

detecting how a user is holding the controller while the controller is detached from the main body; and

changing a user interface mode of the controller based on how the user is holding the controller.

15. The method of claim 11, further comprising:

detecting a direction of the controller; and

changing a user interface mode of the controller based on the detected direction of the controller.

16. The method of claim 11, wherein the controller transmits a control signal to the main body through a direct electrical contact while the controller is attached to the main body.

17. A controller for a multimedia device which is detachable from a main body of the multimedia device, wherein the controller is configured to:

function as a control panel of the main body while attached to the main body; and

function as a remote control of the main body while detached from the main body.

18. The controller of claim 17, wherein the controller comprises:

an input unit configured to display at least two user interface modes;

a first sensor unit configured to detect an attached and detached state of the controller; and

a controlling unit configured to change a user interface mode of the input unit based on the attached or detached state of the controller detected by the first sensor unit.

19. The controller of claim 18, wherein the input unit comprises a touch screen panel,

the controlling unit is configured to display a first user interface input window on the touch screen panel in response to the first sensor unit detecting that the controller is attached to the main body and display a second user interface input window on the touch screen panel in response to the first sensor unit detecting that the controller is detached from the main body, and

the first user interface input window and the second user interface input window are different from each other.

20. The controller of claim 17, further comprising a second sensor unit configured to detect how a user is holding the controller,

wherein the controlling unit is configured to change a user interface mode of the input unit based on how the user is holding the controller.
