Months ago, it was just rumored; two days ago, it was confirmed a work-in-progress; and on Thursday night, Google co-founder Sergey Brin proved the now infamous Google glasses exist -- at least in prototype form.
Tech critics Robert Scoble and Thomas Hawk spotted Brin sporting the prototype frames and lens at a charity event in San Francisco.
The pair photographed Brin, writing on their Google+ page that the glasses looked "very light and most of the people around had no idea that the glasses were pretty special."
Scoble also noted that when he approached Brin, the glasses "were flashing blue and looked like they were processing information." Brin did not let anyone try out the glasses.
On Thursday, Google released a promotional video showing how they want the glasses to work. In the video, the glasses feature characteristics typically found in smartphones such as directions with GPS, voice-to-text messaging, camera features, reminders and weather forecasts.
The key component of the technology would be based on augmented reality, which would allow the glasses to identify items you are looking at and provide you information about those items on the glasses lens.
"A group of us from Google[x] started Project Glass to build this kind of technology, one that helps you explore and share your world, putting you back in the moment," Google wrote on its Google+ page.
No official word from Google when the product might be fully developed but tech bloggers speculate it could launch by the end of the year and cost anywhere from $250-$500.
