Abstract
A data input device is disclosed herein. The input device includes a body having a rearward face and a forward face. Provided on the forward face is a display, and provided on the rearward face is a keyboard. The input device is configured to display a ghost image of the keyboard on the display to allow the user to locate the keys on the rearward face of the input device without having to turn the device around. The input device allows the user to operate a keyboard on the rear of the input device to increase the usable surface area of the display without having to include the extra bulk and size associated with a separate keyboard located adjacent the display.
