Abstract

An electronic device and method providing a touch-based interface for a display control is provided. The electronic device includes a display, and a processing unit. The display includes a screen installed with a cursor thereon and a frame attached to the screen. The frame further has a first touch sensitive region and a second touch sensitive region for generating sensing signals in response to an input operation. Each sensing signal is assigned a coordinate for identification. The processing unit identifies the sensing signals according to the coordinates assigned therewith, controls a movement of the cursor displayed on the screen if the identified sensing signals from the first touch sensitive region, and controls a movement of pages displayed on the screen if the identified sensing signals from the second touch sensitive region. A related method is also provided.

Claims

1. An electronic device providing a touch-based interface for a display control, the device comprising:

a display having a screen installed with a cursor thereon and a frame attached to the screen, the frame comprising a first touch sensitive region and a second touch sensitive region for generating sensing signals in response to an input operation, each sensing signal being assigned with a corresponding coordinate for identification; and

a processing unit being programmed for identifying the sensing signals according to the coordinates assigned to the sensing signals, and controlling a movement of the cursor displayed on the screen if the identified sensing signals are generated from the first touch sensitive region, and controlling a movement of pages displayed on the screen if the identified sensing signals are generated from the second touch sensitive region.

2. The device according to claim 1, wherein each touch sensitive region further comprises a plurality of sensing units thereunder, each of which has a sensing signal processing circuit for generating the sensing signals.

3. The device according to claim 2, further comprising a timer for recording a time duration of continuously receiving the sensing signals.

4. The device according to claim 3, wherein the processing unit determines a direction of the input operation according to the coordinates assigned to the sensing signals and a speed of the input operation according to the time duration of the timer.

5. The device according to claim 4, wherein the processing unit further determines the speed of the input operation on the first touch sensitive region is a normal speed if the time duration is greater than a first predetermined value, and moves the cursor on the screen word by word.

6. The device according to claim 5, wherein the processing unit further determines the speed of the input operation on the first touch sensitive region is a high speed if the time duration is less than or equal to the first predetermined value, and moves the cursor on the screen line by line.

7. The device according to claim 4, wherein the processing unit further determines the speed of the input operation on the second touch sensitive region is a normal speed if the time duration is greater than a second predetermined value, and flips a single page on the screen.

8. The device according to claim 7, wherein the processing unit further determines the speed of the input operation on the second touch sensitive region is a high speed if the time duration is less than or equal to the second predetermined value, and flips a number of pages on the screen.

9. A touch-based method for a display control on an electronic device, the method comprising the steps of:

providing a display on the electronic device, the display having a screen installed with a cursor thereon and a frame attached to the screen, the frame comprising a first touch sensitive region and a second touch sensitive region for generating sensing signals in response to an input operation, each sensing signals being assigned with a corresponding coordinate for identification;

identifying the sensing signals according to the coordinates assigned to the sensing signals;

controlling a movement of the cursor displayed on the screen if the identified sensing signals are generated from the first touch sensitive region; and

controlling a movement of pages displayed on the screen if the identified sensing signals are generated from the second touch sensitive region.

10. The method according to claim 9, further comprising the steps of:

recording a time duration of continuously receiving the sensing signals;

determining a direction of the input operation according to the coordinates assigned to the sensing signals and a speed of the input operation according to the time duration.

11. The method according to claim 10, wherein the determining step further comprises the steps of:

determining the speed of the input operation on the first touch sensitive region is a normal speed if the time duration is greater than a first predetermined value; and

determining the speed of the input operation on the first touch sensitive region is a high speed if the time duration is less than or equal to the first predetermined value.

12. The method according to claim 11, wherein the step of controlling a movement of the cursor further comprises the steps of:

moving the cursor on the screen word by word if the speed of the input operation on the first touch sensitive region is the normal speed; and

moving the cursor on the screen line by line if the speed of the input operation on the first touch sensitive region is the high speed.

13. The method according to claim 11, wherein the step of controlling a movement of pages displayed on the screen further comprises the steps of:

flipping a single page on the screen if the speed of the input operation on the second touch sensitive region is a normal speed; and

flipping a number of pages on the screen if the speed of the input operation on the second touch sensitive region is a high speed.
