Abstract

Provided is a gesture-based user interface method and apparatus to improve convenience in manipulation of the gesture-based user interface. The gesture-based user interface method includes detecting an input position, determining at least one gesture that can be input in the detected position, and displaying at least one guide corresponding to the determined at least one gesture on a screen.

Claims

1. A gesture-based user interface method comprising:

detecting an input position;

determining at least one gesture input in the detected input position; and

displaying at least one guide corresponding to the determined at least one gesture on a screen.

2. The gesture-based user interface method of claim 1, wherein the detecting of the input position comprises detecting a position touched using a touch-based input device at predetermined time intervals.

3. The gesture-based user interface method of claim 1, further comprising:

dividing the screen into regions; and

assigning a gesture to each of the regions.

4. The gesture-based user interface method of claim 1, wherein the displaying of the at least one guide on the screen further comprises determining at least one image corresponding to the at least one gesture as the guide to be displayed on the screen.

5. The gesture-based user interface method of claim 1, further comprising changing the at least one guide displayed on the screen according to a change of the input position.

6. The gesture-based user interface method of claim 1, further comprising removing the displayed at least one guide from the screen if the input position is not detected.

7. A computer-readable recording medium having recorded thereon a program for implementing the gesture-based user interface method of claim 1.

14. The gesture-based user interface method of claim 1, wherein the detected input position is on the screen.

15. The gesture-based user interface method of claim 1, wherein the at least one gesture is determined based on a region of a touch-based input device within which the input position is contained.

16. The gesture based user interface method of claim 1, wherein the at least one gesture is determined based on changes in the input position.

8. A gesture-based user interface apparatus comprising:

a gesture input unit operable to detect an input position;

a gesture processing unit operable to determine at least one gesture that can be input in the detected input position; and

a central processing unit operable to read at least one guide corresponding to the determined at least one gesture from a storing unit and display the at least one guide on a screen.

9. The gesture-based user interface apparatus of claim 8, wherein the gesture input unit is a touch-based input device that detects a position touched by a user at predetermined time intervals.

10. The gesture-based user interface apparatus of claim 8, wherein the gesture processing unit is operable to divide the screen into regions and assign a gesture to each of the regions.

11. The gesture-based user interface apparatus of claim 8, wherein the central processing unit is operable to determine at least one image corresponding to the at least one gesture as the guide to be displayed on the screen.

12. The gesture-based user interface apparatus of claim 8, wherein the central processing unit is operable to change the at least one guide displayed on the screen according to a change of the input position.

13. The gesture-based user interface apparatus of claim 8, wherein the central processing unit removes the displayed at least one guide from the screen if the input position is not detected.
