ABSTRACT:
A personal computer includes a flat panel or LCD display for displaying computer status information. The display includes an overlying transparent touchpad. When the touchpad is touched, appropriate signals are processed so that movements of the user's finger on the touchpad can be indicated by displaying altered images on the display that correspond to the movement of the user's finger. In this way, the user gets an immediate visual feedback through the LCD display of what changes can be or have been made by touchpad control.
