On a recent (and always delightful) episode of Charlie Rose, features the founder of Google X Sebastian Thrun, who is the second person that has publicly used Project Glass. In the episode, he takes a photo of Mr. Rose using the camera found in the glasses, which can be seen above. The TV cameras, on the outside also were able to see the battery pack of the glasses. He takes the photo by tapping the glasses, then submits it to Google+ by nodding twice. Unbelievable? Yes. See the source link for the full video, and if interested in the glasses rather the majority of the discussion focusing on higher education and future projects, skip to the 30 second mark.
