New feature surfaces
Google's Sergey Brin has been wearing and showing off early prototype versions of the Project Glass glasses for a while. These glasses have a little screen that gives you augmented reality information over the top of your normal vision. Brin was on TV show recently called The Gavin Newsom Show and we learned a new fact during the show.
Brin allowed the host to wear the glasses and take photos using the glasses. The host revealed that the glasses are controlled by an integrated touchpad on the right earpiece. I would assume that trackpad would allow you to scroll through images you've taken and possibly control a cursor. Brin also noted that he hopes technology for the glasses will be available next year.
