Quote from popsci:
"Dubbed Recognizr, the app essentially works like this: the user points the camera at a person across the room. Face recognition software creates a 3-D model of the person's mug and sends it across a server where it's matched with an identity in the database. A cloud server conducts the facial recognition since and sends back the subject's name as well as links to any social networking sites the person has provided access to."
This tech has been around for ages. (see Mistry's first sixth sense TED talk) Guess it was only a matter of time...
Can't wait to see how the Germans react to this one.
