Abstract

Function selection system and method for use in an electronic device are provided. The system includes a display unit and a processing unit. The display unit has a display area, and displays a specific region within the display area. The processing unit selects one of a plurality of functions according to a position of the specific region in the display area. The specific region is removable, and used to display data generated by the selected function.

Claims

1. A function selection system for use in an electronic device, comprising:

a display unit having a display area, and displaying a specific region within the display area; and

a processing unit selecting one of a plurality of functions according to a position of the specific region in the display area,

wherein the specific region is removable, and used to display data generated by the selected function.

2. The system of claim 1, wherein the processing unit further displays a figure corresponding to the selected function in the specific region via the display unit.

3. The system of claim 1, wherein the processing unit further displays a control interface corresponding to the selected function in a region of the display area except the specific region via the display unit.

4. The system of claim 1, wherein the processing unit further determines whether the position of the specific region in the display area has been moved, and when the position of the specific region in the display area is moved, re-selects one of the functions according to the position of the moved specific region.

5. The system of claim 4, wherein the display unit comprises a touch-sensitive screen, and the processing unit determines whether the position of the specific region in the display area has been moved by determining whether at least one contact corresponding to at least one specific position of the specific region on the touch-sensitive screen is detected, and whether the contact is moved.

6. The system of claim 4, further comprising a sensor to detect a position of an input tool, and the processing unit determines whether the position of the specific region in the display area has moved by determining whether the detected position of the input tool is moved.

7. The system of claim 1, wherein the display unit comprises a touch-sensitive screen, and the processing unit further determines whether contacts respectively corresponding to two edges of the specific region on the touch-sensitive screen are detected, and determines whether the contacts have moved closer to each other, and when the contacts are detected and have moves closer to each other, the processing unit locks the display unit.

8. The system of claim 7, wherein the processing unit further adjusts a size of the specific region according to the positions of the contacts.

9. The system of claim 7, wherein the processing unit further determines whether contacts respectively corresponding to the two edges of the specific region on the touch-sensitive screen are detected, and determines whether the contacts have moved apart, and when the contacts are detected and does moved apart, the processing unit unlocks the display unit.

10. A function selection method for use in an electronic device, comprising:

displaying a specific region within a display area of a display unit; and

selecting one of a plurality of functions according to a position of the specific region in the display area when the specific region is removable.

11. The method of claim 10, further comprising displaying a figure corresponding to the selected function in the specific region via the display unit.

12. The method of claim 10, further comprising displaying a control interface corresponding to the selected function in a region of the display area except the specific region via the display unit.

13. The method of claim 10, further comprising:

determining whether the position of the specific region in the display area has moved; and

when the position of the specific region in the display area is moved, re-selecting one of the functions according to the position of the moved specific region.

14. The method of claim 13, wherein the display unit comprises a touch-sensitive screen, and the determination of whether the position of the specific region in the display area has moved is performed by determining whether at least one contact corresponding to at least one specific position of the specific region on the touch-sensitive screen is detected, and whether the contact is moved.

15. The method of claim 14, wherein the at least one specific position comprises any position on the specific region or at least two edges of the specific region.

16. The method of claim 13, wherein the display unit comprises a touch-sensitive screen, and the determination of whether the position of the specific region in the display area has moved is performed by determining whether a contact corresponding to a scroll bar displayed in the touch-sensitive screen is detected, and whether the contact is moved.

17. The method of claim 13, wherein the determination of whether the position of the specific region in the display area has moved is performed by determining whether a control key is operated, wherein the control key is used to determine the position of the specific region in the display area.

18. The method of claim 13, wherein the determination of whether the position of the specific region in the display area has moved is performed by determining whether a position of an input tool detected by a sensor is moved.

19. The method of claim 10, wherein the display unit comprises a touch-sensitive screen, and the method further comprises the steps of:

determining whether contacts respectively corresponding to two edges of the specific region on the touch-sensitive screen are detected;

determining whether the contacts have moved closer to each other; and

when the contacts are detected and does move closer to each other, locking the display unit.

20. The method of claim 19, further comprising:

determining whether contacts respectively corresponding to the two edges of the specific region on the touch-sensitive screen are detected;

determining whether the contacts have moved apart; and

when the contacts are detected and does moved apart, unlocking the display unit.
