Have you ever wondered of a touchscreen display identifying finger prints? If so, wait for some more time as it is almost closer to reality. In a way it would redefine online security and revolutionize human and computer interaction. To make the current touch screens identify fingerprints, it is essential that a supplement sensor needs to be accommodated. Researchers Christian Holz and fellow researcher Patrick Baudisch have modeled a prototype that uses a glass screen, made of millions of 3 millimetre-long optical fibres that are bunched together vertically. From an image projector that is mounted below the glass, each fibre is able to pipe out visible light rays. Meanwhile, from a source adjacent to the projector, an infrared light bounces off the fingerprints and back down to an infrared camera.
Wait and watch for this about-to-come new technology!
