Abstract
An improved computer or PDA with a projected display onto a substantially flat, white surface to create a virtual computer screen display and a projected keyboard onto the substantially flat, white surface and a laser sensor projected over the keyboard and parallel to the substantially flat, white surface to create a virtual keyboard. The virtual display and virtual keyboard permit the computer or PDA to be substantially smaller than typical computers or PDA's, while also permitting a relatively normal size display and keyboard/user input area.
