Abstract

The present invention relates to displaying information on a touch screen of an electronic device. The present invention includes displaying information on a touch screen, sensing at least two points on the touch screen being touched, resizing the information displayed according to a distance between the at least two touched points, and displaying the resized information on the touch screen.

Claims

1. A method for displaying information on a touch screen of an electronic device, the method comprising:

displaying information on a touch screen;

sensing at least two points on the touch screen being touched;

resizing the information displayed according to a distance between the at least two touched points; and

displaying the resized information on the touch screen.

2. The method of claim 1, wherein the information comprises at least one of:

image data;

video data;

map data;

text data; and

webpage data.

3. The method of claim 1, wherein the information is resized according to a comparison of the distance between the at least two touched points and a reference distance.

4. The method of claim 1, wherein the size of the information is enlarged when the distance between the at least two touched points is greater than the reference distance.

5. The method of claim 4, wherein the size of the information is uniformly enlarged for any distance between the at least two touched points greater than the reference distance.

6. The method of claim 4, wherein the size of the information is proportionally enlarged according to a ratio of the distance between the at least two touched points and the reference distance.

7. The method of claim 6, wherein the size of the information is proportionally enlarged discretely.

8. The method of claim 1, wherein the size of the information is reduced when the distance between the at least two touched points is lesser than a reference distance.

9. The method of claim 8, wherein the size of the information is uniformly reduced for any distance between the at least two touched points lesser than the reference distance.

10. The method of claim 8, wherein the size of the information is proportionally reduced according to a ratio of the distance between the at least two touched points and the reference distance.

12. The method of claim 1, wherein the information is resized according to a reference table in which a plurality of sizes are respectively matched to a plurality of distances between the at least two touched points.

13. The method of claim 12, wherein the reference table is provided by the electronic device.

14. The method of claim 12, wherein the plurality of sizes respectively matched to the plurality of distances in the reference table are determined by a user.

15. The method of claim 3, wherein the reference distance is provided by the electronic device.

16. The method of claim 3, wherein the reference distance is determined by a user.

17. The method of claim 3, further comprising displaying an indicator for indicating the reference distance on the touch screen.

18. The method of claim 1, wherein the information is resized upon sensing the at least two points being touched N times within a certain time period, where N is an integer greater than 1.

19. The method of claim 1, wherein the information is displayed on a portion of the touch screen and the at least two touched points are sensed on the entire touch screen.

20. The method of claim 1, wherein the information is displayed on a portion of the touch screen and the at least two touched points are sensed on the portion of the touch screen.

11. The method of claim 11, wherein the size of the information is proportionally reduced discretely.

21. An electronic device for displaying information, the electric device comprising:

a touch screen for displaying information; and

a controller for sensing at least two points on the touch screen being touched, resizing the information displayed according to a distance between the at least two touched points, and displaying the resized information on the touch screen.

22. The electronic device of claim 21, wherein the information comprises at least one of:

image data;

video data;

map data;

text data; and

webpage data.

23. The electronic device of claim 21, wherein the information is resized according to a comparison of the distance between the at least two touched points and a reference distance.

24. The electronic device of claim 21, wherein the size of the information is enlarged when the distance between the at least two touched points is greater than a reference distance.

25. The electronic device of claim 24, wherein the size of the information is uniformly enlarged for any distance between the at least two touched points greater than the reference distance.

26. The electronic device of claim 24, wherein the size of the information is proportionally enlarged according to a ratio of the distance between the at least two touched points and the reference distance.

27. The electronic device of claim 26, wherein the size of the information is proportionally enlarged discretely.

28. The electronic device of claim 21, wherein the size of the information is reduced when the distance between the at least two touched points is lesser than a reference distance.

29. The electronic device of claim 28, wherein the size of the information is uniformly reduced for any distance between the at least two touched points lesser than the reference distance.

30. The electronic device of claim 28, wherein the size of the information is proportionally reduced according to a ratio of the distance between the at least two touched points and the reference distance.

31. The electronic device of claim 30, wherein the size of the information is proportionally reduced discretely.

32. The electronic device of claim 21, wherein the information is resized according to a reference table in which a plurality of sizes are respectively matched to a plurality of distances between the two touched points.

33. The electronic device of claim 32, wherein the reference table is provided by the electronic device.

34. The electronic device of claim 32, wherein the plurality of sizes respectively matched to the plurality of distances in the reference table are determined by a user.

35. The electronic device of claim 23, wherein the reference distance is provided by the electronic device.

36. The electronic device of claim 23, wherein the reference distance is determined by a user.

37. The electronic device of claim 23, wherein the touch screen displays an indicator for indicating the reference distance.

38. The electronic device of claim 21, wherein the information is resized upon the controller sensing the two points being touched N times within a certain time period, where N is an integer greater than 1.

39. The electronic device of claim 21, wherein the information is displayed on a portion of the touch screen and the at least two touched points are sensed on the entire touch screen.

40. The electronic device of claim 21, wherein the information is displayed on a portion of the touch screen and the at least two touched points are sensed on the portion of the touch screen.
