A pointer control method comprises a providing pointer upon a position input apparatus. Then a corresponding distance table is generated according to a moving distance of the pointer upon the position input apparatus, and a pressure gradient value range corresponding to the distance table is generated. A pressure table according to the pressure gradient value range is also generated. Finally, a tip pressure of the pointer is calculated according to a maximum pressure gradient value in the pressure gradient value range and a pressure gradient value corresponding to the moving distance of the pointer.
