As you hear about Google Glass everywhere, I assume that, just like me, you're willing to know how it works and what the technology is. This simple infographic made by Martin Missfelds explains the technology behind Google Glass.
The device owns a battery, a CPU (Computer Process Unit) including a GPS, a camera allowing the user to record videos and take pictures, a speaker, a microphone and a prism to superpose the virtual layer on the reality.
The real question is : how comes we get a sharp image? The technology is based on a mini projector. Via a prism and a projector a virtual layer is placed over reality. The prism projects the computer image directly onto the retina. Despite being very close to the eye, the image is bright and clear and because the image is slightly transparent, you can comfortably place it right in front of your eyes. The technology is simple science and at the beginning the main challenge of Google was to cater the glasses to people who wear prescription lenses, but it looks like it's not a challenge anymore!
