(2) A representation of a keyboard projected onto a flat surface such as a desktop. Using the fingers as you would a normal keyboard, tapping the keys on this image of a keyboard is picked up by an optical or electronic beam. Such a device enables PDAs and other small handhelds to create a full-size keyboard.
