| Abstract: |
An improved computer or PDA (100) with a projected display onto a substantially flat, white surface (102, 200) to create a virtual computer screen display (104) and a projected keyboard (108) onto the substantially flat, white surface (102, 200) and a laser sensor (202) projected over the keyboard and parallel to the substantially flat, white surface (102, 200) to create a virtual keyboard (108). The virtual display (104) and virtual keyboard (108) permit the computer or PDA (100) to be substantially smaller than typical computers or PDA's, while also permitting a relatively normal size display and keyboard/user input area.
