Abstract

The present invention relates to a mobile terminal. Specifically to a mobile terminal including a display including a touchscreen, a sensing unit for sensing an object contacting the touchscreen and the object in near-proximity to the touchscreen, and a controller for controlling information appearing on the display according to the object contacting the touchscreen and movement of the object relative to the touchscreen.

Claims

1. A mobile terminal, comprising:

a display including a touchscreen;

a sensing unit for sensing an object contacting the touchscreen and the object in near-proximity to the touchscreen; and

a controller for controlling information appearing on the display according to the object contacting the touchscreen and movement of the object relative to the touchscreen.

2. The mobile terminal of claim 1, wherein the controller applies a scrolling function to the information appearing on the display when the object contacts a predetermined point on the touchscreen and moves away from the predetermined point while in near-proximity to the touchscreen.

3. The mobile terminal of claim 2, wherein the controller applies the scrolling function as long as the distance moved by the object is greater than or equal to a predetermined distance.

4. The mobile terminal of claim 2, wherein the controller controls a scroll speed according to the distance moved by the object.

5. The mobile terminal of claim 2, wherein the controller controls at least one of a scroll direction and a scroll speed according to a direction of movement of the object.

6. The mobile terminal of claim 1, wherein the controller applies a zoom function to the information appearing on the display when the object contacts a predetermined point on the touchscreen and moves away from the predetermined point while in near-proximity to the touchscreen.

7. The mobile terminal of claim 1, wherein the controller applies a rotation function to the information appearing on the display when the object contacts a predetermined point on the touchscreen and rotationally moves with respect to the predetermined point while in near-proximity to the touchscreen.

8. The mobile terminal of claim 1, wherein the controller displays a function icon when the object is near-proximity to the touchscreen.

9. The mobile terminal of claim 8, wherein the controller applies a zoom function to the information appearing on the display when the object contacts a predetermined portion of the function icon and linearly moves with respect to the predetermined portion while contacting the touchscreen.

10. The mobile terminal of claim 8, wherein the controller applies a rotation function to the information appearing on the display when the object contacts a predetermined portion of the function icon and rotationally moves with respect to the predetermined portion while contacting the touchscreen.

11. A method for controlling information displayed on a mobile terminal, the method comprising:

displaying information on a display of a touchscreen;

sensing an object contacting the touchscreen and the object in near-proximity to the touchscreen; and

controlling the information appearing on the display according to the object contacting the touchscreen and movement of the object relative to the touchscreen.

12. The method of claim 11, further comprising applying a scrolling function to the information appearing on the display when the object contacts a predetermined point on the touchscreen and moves away from the predetermined point while in near-proximity to the touchscreen.

13. The method of claim 12, further comprising applying the scrolling function as long as the distance moved by the object is greater than or equal to a predetermined distance.

14. The method of claim 12, further comprising controlling a scroll speed according to the distance moved by the object.

15. The method of claim 12, further comprising controlling at least one of a scroll direction and a scroll speed according to a direction of movement of the object.

16. The method of claim 11, further comprising applying a zoom function to the information appearing on the display when the object contacts a predetermined point on the touchscreen and moves away from the predetermined point while in near-proximity to the touchscreen.

17. The method of claim 11, further comprising applying a rotation function to the information appearing on the display when the object contacts a predetermined point on the touchscreen and rotationally moves with respect to the predetermined point while in near-proximity to the touchscreen.

18. The method of claim 11, further comprising displaying a function icon when the object is near-proximity to the touchscreen.

19. The method of claim 18, further comprising applying a zoom function to the information appearing on the display when the object contacts a predetermined portion of the function icon and linearly moves with respect to the predetermined portion while contacting the touchscreen.

20. The method of claim 18, further comprising applying a rotation function to the information appearing on the display when the object contacts a predetermined portion of the function icon and rotationally moves with respect to the predetermined portion while contacting the touchscreen.
