Abstract:
1. An electronic device enabling a cursor control, the device comprising: a display having a screen and a frame attached to the screen, the frame comprising a touch sensitive region for generating sensing signals in response to an input operation, each sensing signal being assigned to a corresponding coordinate for identification, wherein the touch sensitive region comprises a plurality of sensing units thereunder, each of which has a sensing signal processing circuit for generating the sensing signals; a timer for recording a time duration of receiving the sensing signals; and a processing unit for 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 duration of receiving the sensing signals only, and moving the cursor displayed on the screen word by word if the speed of the input operation is in a low-speed range; wherein the processing unit determines the speed of the input operation is in the low-speed range if the time duration of receiving the sensing signals is greater than a first predetermined value.
