METHOD FOR USER INPUT FROM THE BACK PANEL OF A HANDHELD COMPUTERIZED DEVICE
First Claim
1. A method of assisting user data entry into a handheld computerized device, said handheld computerized device comprising at least one touchpad, at least one graphics display screen, at least one processor, memory, and software, said method comprising:
- displaying at least one data entry location on said at least one graphics display screen of said handheld computerized device;
obtaining data on the location and movement of the user'"'"'s fingers and/or hand using said touchpad;
said touchpad being located in a location of said handheld computerized device that is different from the location of said at least one display screen;
analyzing said data on the location and movement of said user'"'"'s fingers and/or hand according to a biomechanical and anatomical model of a human hand, and assigning said data on the location and movement of said user'"'"'s fingers and/or hand to specific fingers on said biomechanical and anatomical model of said human hand;
using said biomechanical and anatomical model of said human hand to compute a graphical representation of at least said user'"'"'s fingers;
displaying said graphical representation of at least said user'"'"'s fingers on said at least one graphics display screen of said handheld computerized device;
wherein distances between said graphical representation of at least said user'"'"'s fingers on said at least one graphics display screen, and said at least one data entry location, give information to said user to facilitate said user to position said user'"'"'s fingers and/or hand on said at least one touchpad to enter user data into said at least one data entry location.

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.
