Abstract

A device and method for enlarging and reducing data is disclosed. Input from a stylus is detected. It is identified whether the input corresponds to enlargement or reduction of the data. A guide is displayed, when the input corresponds to enlargement or reduction of the data. The data is enlarged or reduced based on the input by the stylus on the guide.

Claims

1. A method comprising:

displaying data on a display of an electronic device;

detecting input from a stylus;

identifying whether the input corresponds to enlargement or reduction of the data;

displaying a guide, when the input corresponds to enlargement or reduction of the data; and

enlarging or reducing the data based on the input by the stylus on the guide.

2. The method of claim 1, wherein identifying whether the input is for enlargement or reduction is based on input information from a switch configured in the stylus.

3. The method of claim 2, wherein identifying whether the input is for enlargement or reduction is based on a hovering state of the stylus.

4. The method of claim 1, wherein displaying the guide comprises:

displaying a guide for enlargement and a guide for reduction such that at least part of the guide for enlargement and at least part of the guide for reduction are symmetric to each other.

5. The method of claim 1, wherein enlarging or reducing the data comprises:

enlarging or reducing the data based on movement detected from the stylus.

6. The method of claim 1, wherein enlarging or reducing the data comprises:

determining an enlargement or reduction magnification based on at least one of a moving distance and a speed of the stylus.

7. The method of claim 6, further comprising:

displaying the magnification on the display.

8. The method of claim 1, further comprising:

identifying a location of a user using information from at least one input module contained in the electronic device.

9. The method of claim 8, wherein identifying the location of the user comprises:

detecting an image using an image acquisition unit of the electronic device.

10. The method of claim 8, further comprising:

identifying a direction of the guide based on the location of the user.

11. The method of claim 10, further comprising:

displaying the guide such that the guide for enlargement is located farther from the location of the user than the guide for reduction.

12. The method of claim 1, further comprising:

removing the guide, when certain input is detected from the stylus.

13. The method of claim 12, wherein the certain input detected from the stylus comprises a release of a switch configured in the stylus and contact of the stylus on the display.

14. An electronic device comprising:

a display;

a controller to;

display data on the display;

detect input from a stylus;

identify whether the input corresponds to enlargement or reduction of data;

display a guide, when the input corresponds to enlargement or reduction of the data; and

enlarge or reduce the data based on the input by the stylus on the guide.

15. The electronic device of claim 14, wherein the controller to further detect whether the input from the stylus is a hovering input.

16. The electronic device of claim 15, wherein the controller to further determine a position of the guide on the display based on input from a switch added to the stylus, when it is determined that the stylus input is the hovering input.

17. The electronic device of claim 14, wherein the controller to further detect a location of a user based at least partially on information from at least one input module.

18. The electronic device of claim 17, wherein the controller to further determine a direction in which to display the guide, based on the location of the user.

19. The electronic device of claim 14, wherein the controller to further determine a direction in which to display the guide based at least partially on setting information of the electronic device or a location of a user.

20. A non-transitory computer readable medium with instructions stored therein which upon execution instructs a device to:

detect input from a stylus;

identify whether the input corresponds to enlargement or reduction of data;

display a guide, when the input corresponds to enlargement or reduction of the data; and

enlarge or reduce the data based on the input by the stylus on the guide.
