Brin is known to run Google X, the part of Google responsible for developing future projects. Google Glasses are new augmented reality technology that combine the features of a smartphone with a heads-up style display integrated into eyewear. Essentially it display computer information in front of your eyes as you walk around. The headset is known as Project Glass within Google.
Augmented reality glasses are said to be one of the next big trends in computer technology, and although they sounds quite futuristic – Google is already seeding prototypes kits to developers, and clearly now testing them out in public.
The glasses are reasonably unobtrusive, and Brin isn’t wearing the oversized eyewear you might expect. They look like a regular pair of sunglasses.
Google has shown off its glasses before, Sergey Brin wore them last year to an event for the blind in San Francisco.
The photograph was taken by passenger Noah Zerkin who recognised Brin and posted the image on Twitter. Zerkin commented that he himself was a “wearable computing and augmented reality enthusiast/hardware prototyper,” but told Twitter that he had got into the same subway carriage as Brin by coincidence. He said he had had had “a brief conversation with the most powerful man in the world. On the downtown 3 train. Nice guy.”
