Project Glass revealed to have physical trackpad along right arm
 

Sergey Brin has appeared on The Gavin Newsom Show on Current TV to drop a few more enticing hints about Project Glass. While showing the presenter a picture he'd taken with the AR glasses, he revealed that the prototype is controlled with a trackpad running down the right* arm. He also talked about the device's genesis in Goggle's X Lab, which he described as an "advanced skunkworks" where "far-out projects" are developed -- it's also the department that occupies most of his time. While the units he and his colleagues have been wearing are very rough prototypes, the Google co-founder shared his private hope that the tech will make its way to general release next year. You can catch the extract in full in the video after the break.

*Right for the wearer, left for the observer. It depends entirely on your perspective.
