Abstract:
The present invention relates to a handheld computerized device with a bit mapped display screen on the front panel, and a touchpad installed on the back panel. More particularly, the invention relates to a method and graphical user interface that enable the user to see the user's finger position and motion from behind the device superimposed upon a virtual keyboard layout on the front panel. This allows the user to use a touchpad keypad on the back of the device to input keystrokes and mouse actions, and these will be reflected on the display screen on the front of the handheld computerized device as “virtual fingers” or equivalent.
