Google has patented its Project Glass augmented reality technology, which marks a further step in bringing the idea to reality.
The search giant filed three patents, numbered D659,739, D659,740 and D659,741, for a “wearable display device” and a “wearable display device frame,” showing several versions of augmented reality glasses, some that have lens and others that are just a frame.

The science-fiction like technology was demonstrated in a video last month, spreading like wildfire across the internet as consumers rooted for what could become the next big thing since smartphones and tablet computers.

Interestingly the patents were filed on 26 October of last year and were granted yesterday, suggesting the company has been working on this idea for some time. Others like Valve and the US military are toying with similar technology, but Google's securing of patents could give it a major advantage against the competition.

The technology is being researched at the company's Google X laboratory and prototypes are being tested by Google's executives, including Sergey Brin and Vic Gundotra, showing support for the technology coming from the very top, which is a good sign for the likelihood that we might see Project Glass on store shelves in the future.
