"Liking" things gets a real-world spin with this prototype out of Pittsburgh-based Deeplocal. The "Like Belt" uses near-field communication technology to register "likes" when you are walking around. You just have to do a bit of thrusting.
Simple enough, the belt has an NFC antenna attached, with an NFC-enabled Android phone. It recognizes RFID chips embedded in objects. So when you thrust your hips at something, it will register a "like."
It could, potentially, be also used for other things, like location based-marketing to register check-ins or, as Wired points out, in dating, although we don't know how well people may react to that .
