Sixth Sense is a multi-component wearable multi-function device invented by Pranav Mistry, a researcher at MIT’s Fluid Interfaces Group. It was demonstrated at the TED conference in February this year by Belgian Patty Maes, leader of the MIT lab, and this fabulous video describes the various features, and potential applications. Since one of the demonstrated applications is a map interface, I’m including it here, but the coolest thing (to me), is a watch created by drawing a circle on your wrist. As I perpetually lose watches, this would be the perfect solution.
Update 4/7/2018: Pranav Mistry is now head of research for Samsung.
