How Google Glass works

While Google Glass is being heralded as the next big thing in smart devices, there are still a lot of questions surrounding the technology.

For one, how does it work? Also, how is it able to layer a digital image over the image of reality, a technique referred to as “augmented reality”? Brille-kaufen.org has put together the following Infographic that details from top to bottom how Google Glass works in a very simple and easy-to-understand manner. 

So it appears as though the key to the technology is the device’s mini projector, which uses a semi-transparent prism to project the digital image directly into the user’s retina (sounds harmless, right?) Even though the image is really close to one’s eye, everything’s still crystal clear. And because it’s slightly transparent, it can be placed right in front of the user’s eye without becoming a visual hindrance.

The author behind the Infographic, Martin Missfledt, concludes that the biggest challenge Google now faces with this device is making it usable for people with normal glasses. Right now, Google Glass needs to be placed ahead of normal glasses, which neither looks good nor feels comfortable for the user. Missfledt suggests that Google might have to manufacture individual customized prisms for these users, but that could wind up being a super costly endeavor.
