smartwatch uses the whole screen as a joystick

A team from Carnegie Mellon University developed a concept smartwatch that turns the whole screen into one big input mechanism. Which means you can pan, twist, zoom, tilt and click the screen by physically moving the watch face, just like a joystick. 

The team ported a bunch of apps to show how the technology works. Since the device features several ways to interact with software, it's a lot easier to set the time, scroll down a calendar and navigate a map. And even play a game

The only missing thing here is a design team that will make this smartwatch come to life.
