Ever wondered how Google’s visionary (pun intended) gadget, Google Glass, actually works? Well, artist Martin Missfeldt created an infographic that explains the wonders of technology behind Google’s technologically-enhanced glasses. At the heart of the tech that makes Google Glass tick are a mini projector and a semi-transparent prism which project an augmented reality layer of information directly to the user’s retina. The infographic also touches on arguably one of the biggest hurdles in the design of Google Glass — making it work for people who wear normal glasses.
