Abstract

A portable terminal for sensing a touch input, including a direct touch input and a proximity touch input, includes a touch screen configured to receive the touch input via a touching object and responsively displaying at least a first portion of a page and a controller configured to recognize the direct touch input when the touching object contacts the touch screen and recognize the proximity touch input when the touching object is located within a threshold distance relative to the touch screen for a period of time, the proximity touch input being effective as long as the touching object remains within the threshold distance, wherein in response to the proximity touch input, a size of the displayed page is changed from a first size to a second size, or a second portion of the page is displayed on the touch screen, the second portion being different from the first portion.

2. The method of claim 1, wherein the at least one preview image is displayed on an area adjacent to the first object on the touchscreen.

3. The method of claim 1, wherein the at least one preview image is displayed such that the at least one preview image overlaps the first object on the touchscreen.

4. The method of claim 1, wherein the at least one preview image is displayed on an entire area of the touchscreen.

5. The method of claim 1, wherein the at least one preview image is displayed in a slide-show manner.

6. The method of claim 1, further comprising:

receiving a second proximity touch input over a second object on the touchscreen, the touch media being moved from the first object to the second object while maintaining a distance from the touch screen, the second object including at least one second sub-object; and

displaying at least one preview image corresponding to the at least one second sub-object on the touchscreen while the touch media maintains the second proximity touch input.

7. The method of claim 6, wherein each of the first object and the second object includes an icon corresponding to a prescribed web-page, and each of the first sub-object and the second sub-object includes a browser to the prescribed web-page.

8. The method of claim 1, further comprising:

receiving a first touch input on one of the at least one preview image; and

displaying the first sub-object whose preview image receives the first touch input on the touchscreen.

9. The method of claim 8, wherein the first sub-object whose preview image receives the touch input is displayed on an entire area of the touchscreen.

10. The method of claim 1, further comprising:

recognizing that the first proximity touch input is being released; and

terminating display of the at least one preview image corresponding to the at least one first sub-object.

11. The method of claim 1, further comprising:

receiving a second touch input on the preview image which receives the third proximity touch input; and

displaying the first sub-object whose preview image receives the second touch input as a wallpaper on the touchscreen.

12. The method of claim 1, wherein the first object includes an image folder and the first sub-object includes an image in the image folder.

13. A method for controlling display in a mobile terminal, the method comprising:

displaying a plurality of icons on a touchscreen of the mobile terminal, the plurality of icons being displayed such that the plurality of icons overlaps one another;

receiving a proximity touch input over the icon for a prescribed time by a touch media;

displaying a first portion of the plurality of icons for a predetermined time on the touchscreen while the touch media maintains the proximity touch input; and

displaying a second portion of the plurality of icons for the predetermined time on the touchscreen after displaying the first portion of the plurality of icons,

wherein the first and the second portion of the plurality of icons is displayed in a slide-show manner, and

wherein the first and the second portion of the plurality of icons is displayed on an area where the overlapped plurality of icons is displayed.

14. The method of claim 13, further comprising:

receiving a touch input by the touch media on the area where the overlapped plurality of icons is displayed; and

displaying the plurality of icons on a portion of the touchscreen.

15. A method for controlling display in a mobile terminal, the method comprising:

displaying an icon on a touchscreen of the mobile terminal, the icon including at least one content;

receiving a proximity touch input over the icon for a prescribed time by a touch media;

displaying a preview of the at least one content adjacent to the icon for a predetermined time while the touch media maintains the proximity touch input,

wherein the preview of the at least one content is displayed in a slide-show manner.

16. A mobile terminal comprising:

a touchscreen configured to display a first object including at least one first sub-object; and

a controller configured to;

receive a first proximity touch input over the first object by a touch media for a prescribed time, and

control the touchscreen to display at least one preview image corresponding to the at least one first sub-object while the touch media maintains the first proximity touch input.
