The idea of using a projection keyboard in conjunction with the mobile device operated by manufacturers for a long time, acquiring and improving modifications. On the surface of the table are projected virtual keys, pressing that corresponds to the overlap of the corresponding surface area by the finger - this is followed by a high-precision optical sensor.
Japanese colleagues during the regular raids on neighboring markets found on sale the world's first mouse projection Serafim ODIN .
The principle of operation of this virtual manipulator is similar to the projection keyboard, with the only difference being that in this case simulated operation touch panel - the so-called trackpad. The sensor monitors the movements of the user's finger, controlling a cursor on a computer screen that connects via USB.
The device realizes the traditional touchpad gestures: scrolling and zooming. In the center, between the two soft keys ("left" and "right" within the meaning of manipulators "mouse"), is an additional key, touching which can cause user-programmed functions. Size of the projected surface area is made on a 80 x 80 mm. The device has dimensions of 43.5 x 52.4 x 24 mm, weight up to '40
