Abstract

An electronic device and a method of operating the same are provided. The electronic device includes a touch-sensing module sensing a change in a touch, a processing module determining a display screen layer associated with a touch location, and a screen display module displaying a part of the display screen layer.

Claims

1. An electronic device comprising:

a touch-sensing module which senses a touch;

a processing module which determines a display screen layer associated with a location of the touch; and

a screen display module which displays a part of the display screen layer.

2. The electronic device of claim 1, wherein the screen display module blurs a portion of the part of the display screen layer at a boundary between the part of the display screen layer and an original display screen layer.

3. The electronic device of claim 1, wherein the screen display module displays the part of the display screen layer such that the part of the display screen layer appears depressed by blurring a boundary between the part of the display screen layer and an original display screen layer.

4. The electronic device of claim 1, wherein the screen display module displays the part of the display screen layer while the part of the display screen layer is displayed in proximity to the location of the touch.

5. The electronic device of claim 1, wherein if the processing module determines a change in the location of the touch, then the screen display module displays another part of the display screen layer based on the changed location of the touch.

6. The electronic device of claim 1, wherein if the processing module determines that the touch is maintained for a period of time, then the screen display module displays a whole of the display screen layer associated with the location of the touch.

7. The electronic device of claim 6, wherein if the processing module determines that the touch is continuously maintained for a period of time after the whole of the display screen layer associated with the location of the touch is displayed, then the screen display module displays a next display screen layer associated with the location of the touch.

8. The electronic device of claim 1, wherein if the processing module determines that pressure exerted to the location of the touch is increased, then the screen display module displays a whole of the display screen layer associated with the location of the touch.

9. The electronic device of claim 8, wherein if the processing module determines that the pressure exerted to the location of the touch is continuously increased after the whole of the display screen layer associated with the location of the touch is displayed, then the screen display module displays a next display screen layer associated with the location of the touch.

10. The electronic device of claim 1, wherein if the processing module determines that the location of the touch is changed within a period of time and the touch is then released, then the screen display module displays a whole of the display screen layer associated with the location of the touch.

11. The electronic device of claim 1, wherein if the processing module determines that the touch is released, then the screen display module displays the display screen layer such that the display screen layer disappears and the original display screen layer is displayed.

12. The electronic device of claim 11, wherein the screen display module displays the display screen layer such that the display screen layer disappears slowly from its edges.

13. A method of operating an electronic device comprising:

sensing a change in a touch;

displaying a part of a display screen layer associated with a location of the touch;

determining a manipulation mode of the change in the touch; and

displaying a changed display screen layer according to the change in the touch.

14. The method of claim 13, wherein a portion of the part of the display screen layer is blurred at a boundary between the part of the display screen layer and an original display screen layer.

15. The method of claim 13, wherein the part of the display screen layer is displayed such that it looks depressed relative to an original display screen layer.

16. The method of claim 13, wherein the displaying of the part of the display screen layer comprises displaying the part of the display screen layer while the part of the display screen layer is displayed in proximity to the location of the touch.

17. The method of claim 13, wherein the determining comprises determining whether the location of the touch has changed, and the displaying of the changed display screen layer comprises displaying another part of the changed display screen layer based on the changed location of the touch.

18. The method of claim 13, wherein the determining comprises determining whether the touch is maintained for a period of time, and the displaying of the changed display screen layer comprises displaying a whole of the display screen layer associated with the location of the touch.

19. The method of claim 18, further comprising:

determining whether the touch is continuously maintained for a period of time after the whole of the display screen layer associated with the location of the touch is displayed; and

displaying a next display screen layer associated with the location of the touch.

20. The method of claim 13, wherein the determining comprises determining whether a pressure of the touch is increased, and the displaying of the changed display screen layer comprises displaying a whole of the display screen layer associated with the touch location.

21. The method of claim 20, further comprising:

determining whether the touch pressure is continuously increased after the whole of the display screen layer associated with the location of the touch is displayed; and

displaying a next display screen layer associated with the location of the touch.

22. The method of claim 13, wherein the determining comprises determining whether the location of the touch is changed within a period of time, and the displaying of the changed display screen layer comprises displaying a whole of the display screen layer associated with the location of the touch.

23. The method of claim 13, wherein the determining comprises determining whether the touch is released, and the displaying of the changed layer comprises displaying the display screen such that the display screen layer disappears and an original display screen layer is displayed.

24. The method of claim 13, wherein the displayed display screen layer disappears slowly from its edges.
