Infographic Shows How Google Glass Works

By Eye² Staff

German artist Martin Missfeldt has created an interesting infographic that shows how Google Glass works. The infographic, published on the website, is based on Missfeldt's review of Google patents and other publicly available information.

In his accompanying notes, Missfeldt called Google Glass "a technical masterpiece" that combines numerous functions and features such as a phone, camera, Internet connection and GPS in a very small unit. He pointed out that the core feature of Google Glass is a visual layer that provides augmented reality on top of the "reality" of what the viewer sees. "This layer opens a door to amazing new possibilities," said Missfeldt.

According to Missfeldt, Google Glass contains a mini-projector, which projects the layer via a semi-transparent prism directly on the retina. Because of this, the image, even though it is so close to the eye, is sharp and clear. You can move the front part of the Google Glass easily to optimize the focus.

"Depending on how you wear the Google Glass, the layer appears in the upper right corner or in the middle of the visual field," Missfeldt said. "When the Google Glass is high on the nose, so that you can practically see through underneath, you must turn the eye up to view the image sharp. Because the prism is semi-transparent you can also place it directly in front of the pupil. In that case, you have the sharp layer directly in front of the eyes."

Missfeldt believes the biggest challenge for Google will now be to make the Google Glass also usable for people with normal glasses, or else make them available with individual prescriptions, which would add considerably to the cost.
