Human‐machine interaction is the inevitable medium for people to obtain information from display devices. The evaluation of interaction technologies consist one of the most important parts of the rapid development of display industry. Fifty years ago, mouse and keyboard had brought about great convenience for people to operate machines, while the transparent capacitive touching technology led by Apple's ‘Iphone’ 10 years ago, revolutionarily enable people to use fingers‐the native and ultimate locating ‘device’ to touch and operate the displays. Until now, most of the ‘touching’ technologies only work on the plane dimensional of screens. While, in this talk, we will show a novel optical touching technology based on sub‐wavelength meta‐materials which cover the incident rays into wave guided light for position detection and interaction. By using roll‐to‐roll nano‐imprinting, larger scale fabrication of the sub‐wavelength optical films have been fulfilled and a prototype of optical touch screen has been made, paving the way to mass commercialization.
