Amazing smart glass can recognize numbers, no added tech required
Thanks to Apple’s impressive array of depth-sensing 3D sensors, the newer model iPhoneslet you unlock them using facial recognition. But what if it didn’t take on-board processing to carry out identification tasks, but it could instead be done by the glass of the smartphone display itself? It sounds crazy, but that’s exactly what researchers at the University of Wisconsin–Madison have been working to bring to life. They have developed a type of smart glass that’s able to recognize images (and maybe one day other things) without needing any sensors, circuits, or even power sources to do so....
