Abstract
Apparatus and method of processing touchpad input information are provided. The method includes mapping an input region of a touchpad to a display region as absolute coordinates, converting contact location coordinates into absolute coordinates, when a pointing tool touches the input region, and moving a mouse pointer displayed on the display region according to the converted contact location coordinates. The input region of a touchpad is mapped to a display region as absolute coordinates such that information can be directly input using the touchpad.
