These glasses, we heard, have a front-facing camera used to gather information and could aid in augmented reality apps. It will also take pictures. The spied prototype has a flash —perhaps for help at night, or maybe it is just a way to take better photos. The camera is extremely small and likely only a few megapixels.
Google glasses (or maybe we should all ’em Google Goggles) will be an interesting AR advance, more science friction happening now, if they do happen. Preview (aka rumor) at 9to5Google.
