Abstract:
1. A pointer control method of a computer system, the computer system having a keyboard, the keyboard comprising a plurality of control keys and a plurality of non-control keys, the non-control keys being arranged in a matrix, and each of the non-control keys having an X coordinate and a Y coordinate individually, the method comprising: detecting a first key event, wherein the first key event refers to that at least two non-control keys are pressed simultaneously; calculating a first coordinate, wherein an X coordinate of the first coordinate is an average value of X coordinates of the at least two non-control keys pressed in the first key event, and a Y coordinate of the first coordinate is an average value of Y coordinates of the non-control keys pressed in the first key event; detecting a second key event after the first key event, and the second key event refers to that one non-control key is pressed; calculating a second coordinate, wherein an X coordinate of the second coordinate is an X coordinate of the non-control key pressed in the second key event, and a Y coordinate of the second coordinate is a Y coordinate of the non-control key pressed in the second key event; calculating a vector defined by the first coordinate and the second coordinate; and control movement of the pointer according to the vector.
