As a biomedical computing student at Queen's University seven years ago, Justin Lee knew he wanted to build his own "internet of things" device - but he didn't want it to be any old "smart" lamp, toaster, or light switch. "I wanted to put a computer into one of the most ubiquitous objects in the history of the human race," he says. He chose the cup. Then, he enlisted Yves Béhar, the esteemed designer behind Jawbone and the OLPC, to build it.
The result is Vessyl, a 13-ounce cup that recognizes any beverage you pour into it, displays its nutritional content, and syncs all your drinking habits to your smartphone.
