Projected keyboards have been around for 3 or so years . I propose that someone produce a projected keyboard that also projects a mousepad. A collapsible, inert mouse (i.e. a mouse-shaped hunk of plastic) could accompany it to make using it feel more natural.
As an interesting note, as with electromagnetic induction mousepads, a projected mousepad allows for cordless mouse usage without need of batteries in the mouse itself.-- aguydude, Mar 22 2008 It could work without a mouse. Drag your fingers around the projected "pad" area, to point. It would need to be able to detect right and left-click, and click-drag. If you mouse over the virtual keypad, maybe it could change to a mousepad automatically.-- Amos Kito, Mar 22 2008 Amos: That would make it a projected touchpad.-- aguydude, Jul 27 2011 The benefit is that the mouse can be inert; the laser and electronics are stationary and external to the mouse.
I don't see why it shouldn't work as a touchpad or a mousepad; just as touch screens can be used with or without a stylus, it could offer better precision or ergonomics with a physical mouse but be usable without one.-- spidermother, Jul 27 2011 random, halfbakery
