We all know Google Glass doesn't need sorcery for you to comfortably see a digital image projected over reality. But just how does it work? This infographic by Martin Missfeldt lays out the way the magic happens in simple terms.


The most important part of the shades is a mini-projector that uses a semi-transparent prism to project the computer image directly onto your retina. Despite being super duper close to your peepers, the image is bright and clear. And because the image is slightly transparent, you can comfortably place it right in front of your eyes. So while there are still some challenges for Google to cater the glasses to people who wear prescription lenses, there's no trickery involved—just simple science. [Brille-Kaufen via Digg]
