This is supposed to be a joke, but is it something people would actually USE? A designer in South Korea built a THIRD EYE that you stick to your forehead to prevent you from bumping into stuff while you're walking around texting on your phone.
It's got a sensor that can tell when you're looking down. And there's a robotic eye that alerts you when you're five feet from walking into something. It's even got a robotic eyelid that opens and closes when it's on or off.
The guy who made it says it's supposed to be satire, and he hopes it shows people how ridiculous their smartphone addiction is.
