Abstract

An input method for use in an electronic device having a touch-sensitive screen is disclosed. The method comprises the following steps. An input signal is first received. Then, at least one control item corresponding to the specific program is displayed on the touch-sensitive screen in which the control item has a corresponding control area within the touch-sensitive screen. Next, it is determined whether a confirmation input signal inputted to the corresponding control area of the touch-sensitive screen is detected. A parameter of the control item is adjusted according to the confirmation input signal when the confirmation input signal has been detected.

Claims

1. An input method for use in an electronic device having a touch-sensitive screen, comprising:

(a) receiving an input signal;

(b) displaying at least one control item on the touch-sensitive screen, wherein the control item has a corresponding control area within the touch-sensitive screen;

(c) detecting whether a confirmation input signal has been inputted to the corresponding control area of the touch-sensitive screen; and

(d) adjusting a parameter of the control item according to the confirmation input signal when the confirmation input signal has been detected.

2. The input method of claim 1, wherein the step of detecting whether the confirmation input signal has been inputted to the corresponding control area of the touch-sensitive screen further comprises:

detecting whether a plurality of input signals have been touched on the corresponding control area of the touch-sensitive screen.

3. The input method of claim 2, further comprising:

decreasing said parameter when said signal responsive to a corresponding area has been detected.

4. The input method of claim 2, further comprising:

increasing said parameter when said signal responsive to a corresponding area has been detected.

5. The input method of claim 2, further comprising:

setting the parameter of the control item according to the amount of detected input signals.

6. The input method of claim 2, further comprising:

converting the confirmation input signal to an adjustment signal for adjusting the parameter of the control item based on a specific rule.

7. The input method of claim 1, further comprising:

detecting whether the signal touched on the corresponding control area is a lightly pressed signal or a heavily pressed signal.

8. The input method of claim 7, further comprising:

respectively decreasing or increasing the parameter of the control item according to whether the signal touched within the corresponding control area is a lightly pressed signal or a heavily pressed signal.

9. The input method of claim 1, wherein the confirmation input signal is an interactive signal representing an interaction between the corresponding control area and finger(s), wherein the interactive signal corresponds to a touch-sensitive screen type.

10. The input method of claim 1, wherein the step of displaying at least one control item on the touch-sensitive screen further comprises:

providing a control screen showing the control item and the corresponding control area.

11. The input method of claim 10, wherein the control screen further provides a plurality of control areas each having an indication symbol for indicating a control item corresponding thereto.

12. The input method of claim 1, wherein the control item comprises at least one of a volume control, a brightness control, a channel selection control and a speed control for display.

13. An electronic device, comprising:

a touch-sensitive screen operable in a first mode, displaying a control screen having at least one control item thereon, wherein the control item has a corresponding control area within the control screen;

a detection unit, detecting whether a pointing device is touching the touch-sensitive screen and detecting the interaction between the pointing device and the corresponding control area; and

a processing unit,

wherein when an input signal inputted to the touch-sensitive screen is detected by the detection unit, the processing unit adjusts a parameter of the control item according to the input signal and an interaction signal of the corresponding control area detected by the detection unit.

14. The electronic device of claim 13, wherein the processing unit further comprises:

an analyzing unit, converting the interaction signal to an adjustment signal for adjusting the parameter of the control item based on a specific rule; and

an adjusting unit, adjusting the parameter of the control item according to the adjustment signal generated by the analyzing unit.

15. The electronic device of claim 13, wherein the input signal is generated by a finger(s) or a fingertip(s) of a user or a stylus.

16. The electronic device of claim 15, wherein the processing unit further adjusts the parameter of the control item according to whether the input signal detected by the detection unit is a lightly pressed signal or a heavily pressed signal, when the pointing device is finger(s) of the user.

17. The electronic device of claim 16, wherein the processing unit further decreases the parameter of the control item when an input signal within the control area is detected by the detection unit and increases the parameter of the control item when a plurality of input signals within the control area are detected by the detection unit.

18. The electronic device of claim 16, wherein the processing unit further decreases the parameter of the control item when the input signal within the control area detected by the detection unit is a lightly pressed signal and increases the parameter of the control item when the input signal within the control area detected by the detection unit is a heavily pressed signal.

19. The electronic device of claim 13, wherein the touch-sensitive screen at least comprise a multi-touch panel and a pressure-sensitive touch panel.

20. An input method for use in an electronic device having a touch-sensitive display, comprising:

providing a control screen, wherein the control screen has a plurality of control items each having a corresponding control area within the control screen;

detecting whether an input signal of a first control area corresponding to a first control item of the control items has been generated; and

determining an attribute of the input signal and accordingly adjusting a parameter of the first control item.

21. The input method of claim 20, wherein the determining and adjusting steps further comprises:

decreasing the parameter of the first control item when detecting that an input signal has been inputted to the first control area; and

increasing the parameter of the first control item when detecting that a plurality of input signals have been inputted to the first control area.

22. The input method of claim 20, wherein the determining and adjusting steps further comprises:

decreasing the parameter of the first control item when detecting that a lightly pressed signal has been inputted to the first control area; and

increasing the parameter of the first control item when detecting that a heavily pressed signal has been inputted to the first control area.

23. The input method of claim 20, wherein the control item comprises at least one of a volume control, a brightness control, a channel selection control and a speed control for display.
