Abstract
A method for simulating a mouse with a keyboard in a computer system includes detecting whether a key event occurs in a switch matrix of the keyboard of the computer system, determining whether the key event is related to a specific control key when the key event is detected, transforming a location of a switch in which the key event occurs into a pair of coordinates when the key event is not related to the specific control key and is a key-pressed event, calculating a pair of displacements between the latest two pairs of coordinates to obtain a movement data, and transmitting the movement data to a mouse driver of the computer system so that an operating system of the computer system is capable of receiving the movement data by the mouse driver, for controlling movement of a pointer shown on a screen of the computer system.
