Abstract:
A method for driving a pointing device of a computer system corresponding to movement of a pointer on a screen of a display device, comprising the steps of:determining whether said pointer is positioned in a user interface area on said screen of said display device; determining whether a position of said pointer is changed from a previous position in said user interface area, when said pointer is previously positioned in said user interface area; detecting an amount of a position change of said pointer, when said position of said pointer is changed from said previous position in said user interface area; determining whether said amount of said position change of said pointer corresponds to a button click of said pointing device, said button click performing a function in said computer system; and generating a same pointing signal as a signal that corresponds to said button click to perform said function in said computer system, when said amount of said position change of said pointer corresponds to said button click of said pointing device, said amount of said position change of said pointer, that corresponds to said button click to perform said function in said computer system, corresponding to a moving distance of said pointer and a direction of movement of said pointer, said moving distance of said pointer and said direction of movement of said pointer being determined in relation to an initial reference position, said initial reference position being inside of said user interface area on said screen of said display device.
