If you are a Facebook lover and own an NFC-enabled Android phone, then you can build your own LikeBelt. The LikeBelt designed by Deeplocal as a way to let you update your Facebook using a simple pelvic thrust. The LikeBelt uses Near Field Communication (NFC) to let you check into places, like things and add friends. The range of the LikeBelt is small. Deeplocal’s design seems to be nothing more than a design study at the moment, but the concept is interesting nonetheless. The design of the belt is open source, so you can build one by yourself if you really wanted to. Just make sure you ask strangers before trying to add them.
