Google has sold interactive glasses for $1500 (only) during its annual software conference in San Francisco to first adaptors. If all goes well, a less expensive version of the glasses is expected to go on sale for consumers in early 2014. While wearing these glasses, directions to a destination or a text message from a friend may appear directly before your eyes. Conversing with friends in a video chat, take a photo without taking out a camera, phone or even buy a few things online as you walk around. JUST DON’T DRIVE DOING IT.
