Turn any surface into touch screen

Now you can convert your devices like mobile phone and TV in to touch screen ones a miracle technology from an interactive hardware company called DISPLAX.
                                           Displax skin is a paper thin, transparent and flexible film that transforms any non-metallic in to a interactive touch screen. The film uses projected capacitive technology and has a controller. It can be applied up to three meters across, and detect about 16 finger for a screen as large as 127 cm.
                                           Basically skin uses a grid of nano wires embedded with polymer film. Each time a user make contact with the surface, either by blowing on it or directly touching it, a small electrical disturbance is detected, allowing the microprocessor controller to pinpoint the movement or direction of the air flow.
