The Google Glass Design Patent

Originally filed by Google in August 2011, the “Wearable Device with Input and Output Structure” goes into deep detail on how the Google Glass wearable computer could be constructed, with deep technical schematics describing everything from the frames to the mounting and adjustments, as well as touch pad input and the wireless controls. 

The video camera is shown positioned on the side arm of the frames. Although the diagram show just one camera, more video cameras may be used and may be configured to capture the same view, or different views. 

“The video camera may then be used to generate an augmented reality where computer-generated images appear to interact with the real-world view perceived by the user,” the patent states.
