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 timer for recording a time duration of receiving the sensing signals;

a processing unit being programmed for identifying the sensing signals are generated from which of the touch sensitive regions according to the coordinates assigned to the sensing signals, and 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 of receiving the sensing signals only, and moving a cursor displayed on the screen word by word if the speed of the input operation is a normal speed, upon the identified sensing signals are generated from the first touch sensitive region, and flipping a number of pages if the speed of the input operation is a high speed, upon the identified sensing signals are generated from the second touch sensitive region, wherein the processing unit determines the speed of the input operation on the first touch sensitive region is the normal speed if the time duration of receiving the sensing signals is greater than a first predetermined value; and

the processing unit determines the speed of the input operation on the second touch sensitive region is the high speed if the time duration of receiving the sensing signals is less than or equal to a second predetermined value.

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. 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;

recording a time duration of continuously receiving the sensing signals;

identifying the sensing signals are generated from which of the touch sensitive regions according to the coordinates assigned to 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 of receiving the sensing signals only;

moving a cursor displayed on the screen word by word if the speed of the input operation is a normal speed, upon the identified sensing signals are generated from the first touch sensitive region, wherein the speed of the input operation on the first touch sensitive region is determined to be the normal speed if the time duration of receiving the sensing signals is greater than a first predetermined value; and

flipping a number of pages if the speed of the input operation is a high speed, upon the identified sensing signals are generated from the second touch sensitive region, wherein the speed of the input operation on the second touch sensitive region is determined to be the high speed if the time duration of receiving the sensing signals is less than or equal to a second predetermined value.
