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 touchscreen; and

a controller configured to;

cause the touchscreen to display a content therein, and

concurrently apply a zoom function and a rotation function to the content in response to touch-dragging on the touchscreen with a single pointer with respect to a reference point on the touchscreen, wherein the reference point is a center of the touchscreen.

2. The mobile terminal of claim 1, wherein the zoom function and the rotation function are concurrently applied to the content in response to the single pointer touch-dragged in a direction moving toward and away from the center of the touchscreen while simultaneously touch-dragging in an angle in relation to the center of the touchscreen.

3. The mobile terminal of claim 1, wherein the controller is further configured to display an icon to concurrently apply the zoom function and the rotation function to the content.

4. The mobile terminal of claim 3, wherein the reference point is defined by the icon.

5. The mobile terminal of claim 4, when the icon is dragged to rotate around the reference point, a first rotation angle of the content differs from a second rotation angle of the dragged icon such that the first rotation angle is smaller than the second rotation angle.

6. The mobile terminal of claim 3, wherein the icon is displayed on the content in response to sensing the pointer in near-proximity to the touchscreen for a predetermined time.

7. The mobile terminal of claim 6, wherein the controller is configured to:

in response to sensing the pointer locating in near-proximity to a predetermined location of the touchscreen, display an animation to indicate that the pointer locates in near-proximity to the predetermined location of the touchscreen, and

in response to sensing the pointer staying in near-proximity to the predetermined location of the touchscreen for a predetermined time after the animation is displayed, display the icon on the content.

8. The mobile terminal of claim 3, wherein the zoom function and the rotation function are concurrently applied to the content in response to the single pointer touch-dragged in a direction moving toward and away from the reference point defined by the icon while simultaneously touch-dragging in an angle in relation to the reference point defined by the icon.

9. The mobile terminal of claim 3, wherein the controller is configured to display circles with various sizes according to a length of a radius, and indicate an original magnification of the content by positioning the icon on a specific one of the circles.

10. The mobile terminal of claim 1, further comprising a sensor configured to sense the pointer in near-proximity to the touchscreen.

11. The mobile terminal of claim 10, wherein the sensor is configured to sense the pointer in near-proximity to the touchscreen by using electromagnetic force without a mechanical contact.

12. The mobile terminal of claim 1, wherein the controller is further configured to execute a content scroll function in response to the pointer locating in near-proximity to an edge region of a content display area of the touchscreen.

13. The mobile terminal of claim 12, wherein the edge region includes a first edge region and a second edge region of the content display area, and the controller is configured to:

start scrolling the content in the first scroll direction when the pointer stays in near-proximity to the first edge region for a predetermined time, and

start scrolling the content in the second scroll direction when the pointer stays in near-proximity to the second edge region for a predetermined time.

14. A method of controlling a content displayed on a mobile terminal, the method comprising:

displaying a content on a touchscreen, and

concurrently applying a zoom function and a rotation function to the content in response to touch-dragging on the touchscreen with a single pointer with respect to a reference point on the touchscreen, wherein the reference point is a center of the touchscreen.

15. The method of claim 14, further comprising:

displaying an icon to concurrently apply the zoom function and the rotation function to the content.

16. The method of claim 15, wherein the reference point is defined by the icon.

17. The method of claim 15, wherein the icon is displayed on the content in response to sensing the pointer in near-proximity to the touchscreen for a predetermined time.
