Abstract

A mobile terminal including a terminal body; a touch screen; a plurality of magnetic sensors configured to detect a spatial position of an input device having a magnetic field generating unit; and a controller configured to display a first graphic object notifying an area corresponding to the detected spatial position on the touch screen when the spatial position of the input device is detected adjacent to an edge of the terminal body at an outside of the touch screen without contacting the touch screen, and display a second graphic object notifying a hidden function with respect to a displayed area of the first graphic object on the touch screen when the detected spatial position of the input device is fixed for a predetermined time.

Claims

1. A mobile terminal, comprising:

a terminal body;

a touch screen;

a plurality of magnetic sensors configured to detect a spatial position of an input device having a magnetic field generating unit; and

a controller configured to;

display a first graphic object notifying an area corresponding to the detected spatial position on the touch screen when the spatial position of the input device is detected adjacent to an edge of the terminal body at an outside of the touch screen and without contacting the touch screen, and

display a second graphic object notifying a hidden function with respect to a displayed area of the first graphic object on the touch screen when the detected spatial position of the input device is fixed for a predetermined time.

2. The terminal of claim 1, wherein the controller is further configured to display the first graphic object on an edge area of the touch screen corresponding to the spatial position of the input device.

3. The terminal of claim 2, wherein the controller is further configured to open sub menus of the hidden function when the spatial position of the input device is moved away from or close to a side edge of the terminal body while the second graphic object is displayed.

4. The terminal of claim 3, wherein the controller is further configured to display a changing image on the second graphic object and simultaneously display the sub menus on the changing image in a different manner, based on a degree that the spatial position of the input device is moved away from the side edge of the terminal body within the reference range.

5. The terminal of claim 1, wherein the controller is further configured to decide the hidden function corresponding to the second graphic object based on information displayed on the displayed area of the first graphic object.

6. The terminal of claim 1, wherein the controller is further configured to move at least one of the first and second graphic objects along an edge area of the touch screen, in response to the input device being moved near the edge of the terminal body when the at least one of the first and second graphic objects is displayed.

7. The terminal of claim 1, wherein the controller is further configured to:

detect a moving direction of the spatial position of the input device based on magnetic fields of the magnetic field generating unit detected by the plurality of magnetic sensors, while the second graphic object is displayed, and

generate a different control command with respect to the hidden function corresponding to the second graphic object based on the detected moving direction.

8. The terminal of claim 7, wherein the controller is further configured to execute the hidden function corresponding to the second graphic object in response to the second graphic object being pulled in a second direction different from a first direction, when the spatial position of the input device is moved in the first direction of moving away from the terminal body within the reference range while the second graphic object is displayed.

9. The terminal of claim 8, wherein the controller is further configured to execute the hidden function corresponding to the second graphic object and display an execution result on the touch screen, in response to the spatial position of the input device being moved in the second direction, different from the first direction, within the reference range while the second graphic object is displayed.

10. The terminal of claim 8, wherein the controller is further configured to stop displaying the first and second graphic objects and stop executing the hidden function when the spatial position of the input device is moved out of the reference range.

11. The terminal of claim 1, further comprising:

a microphone disposed on one end of the terminal body,

wherein the controller is further configured to;

display a third graphic object notifying a media reproduction function on an edge area of the touch screen corresponding to the one end when the spatial position of the input device is detected adjacent to the one end at the outside of the touch screen, and

execute a search mode associated with the media reproduction function, in response to the input device being moved near the one end while the third graphic object notifying the media reproduction function is displayed.

12. The terminal of claim 11, wherein the controller is further configured to execute an application associated with the media reproduction function when the spatial position of the input device is moved away from the one end in the search mode.

13. The terminal of claim 1, wherein the controller is further configured to:

switch the first graphic object into a third graphic object notifying a screen scroll function when the spatial position of the input device is moved out of the touch screen and fixed near a side edge of the terminal body for a predetermined time, and

execute the screen scroll ended at a point corresponding to a moved spatial position when the spatial position of the input device is moved near the side edge.

14. The terminal of claim 13, wherein the controller is further configured to adjust a scroll speed of the screen scroll based on a degree that the spatial position of the input device is moved away from the side edge of the terminal body within the reference range.

15. The terminal of claim 13, wherein the controller is further configured to stop the screen scroll and stop displaying the first, second and third graphic objects when the spatial position of the input device is moved away from the side edge of the terminal body out of the reference range.

16. The terminal of claim 13, wherein the controller is further configured to restrict the screen scroll with respect to at least one of objects output on the touch screen when a touch input is applied to the at least one object while the third graphic object notifying the screen scroll function is displayed.

17. The terminal of claim 16, wherein the third graphic object notifying the screen scroll function includes thereon at least part of a position of a current screen, the moved spatial position of the input device and a position of the touch input applied to a first object, while the screen scroll is executed.

18. The terminal of claim 17, wherein the controller is further configured to execute an edit mode for the first object and a second object when the touch input applied to the first object is dragged to an area of the second object included in the current screen, when the screen scroll is stopped or terminated based on the spatial position of the input device.

19. A method of controlling a mobile terminal having a terminal body, the method comprising:

detecting, via a plurality of magnetic sensors, a spatial position of an input device having a magnetic field generating unit;

displaying, via a controller, a first graphic object notifying an area corresponding to the detected spatial position on a touch screen when the spatial position of the input device is detected adjacent to an edge of the terminal body at an outside of the touch screen without contacting the touch screen; and

displaying, via the controller, a second graphic object notifying a hidden function with respect to a displayed area of the first graphic object on the touch screen when the detected spatial position of the input device is fixed for a predetermined time.

20. The method of claim 19, further comprising displaying the first graphic object on an edge area of the touch screen corresponding to the spatial position of the input device.
