Would you like all of your Facebook friends to sift through your trash? A group of designers from Britain and Germany think that you might. Meet BinCam: a "smart" trash bin that aims to revolutionize the recycling process.

BinCam looks just like your average trash bin, but with a twist: Its upper lid is equipped with a smartphone that snaps a photo every time the lid is shut. The photo is then uploaded to Mechanical Turk, the Amazon-run service that lets freelancers perform laborious tasks for money. In this case, they analyze the photo and decide if your recycling habits conform with the gospel of green living. Eventually, the photo appears on your Facebook page.

You are also assigned points, as in a game, based on how well you are meeting the recycling challenge. The household that earns the most points "wins." In the words of its young techie creators, BinCam is designed "to increase individuals' awareness of their food waste and recycling behavior," in the hope of changing their habits.

BinCam has been made possible by the convergence of two trends that will profoundly reshape the world around us. First, thanks to the proliferation of cheap, powerful sensors, the most commonplace objects can finally understand what we do with them—from umbrellas that know it's going to rain to shoes that know they're wearing out—and alert us to potential problems and programmed priorities. These objects are no longer just dumb, passive matter. With some help from crowdsourcing or artificial intelligence, they can be taught to distinguish between responsible and irresponsible behavior (between recycling and throwing stuff away, for example) and then punish or reward us accordingly—in real time.

And because our personal identities are now so firmly pegged to our profiles on social networks such as Facebook and Google +, our every interaction with such objects can be made "social"—that is, visible to our friends. This visibility, in turn, allows designers to tap into peer pressure: Recycle and impress your friends, or don't recycle and risk incurring their wrath.
