It ain't easy using a smartwatch, especially if you have gigantic fingers. So, a team from Carnegie Mellon University developed a concept smartwatch that turns the whole screen into one relatively big input mechanism. By that, we mean you can pan, twist, zoom, tilt and click the screen by physically moving the watchface -- the whole thing (sans the bracelet) is essentially a joystick. As you can see in the video after the break, 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, yes, the technology makes it possible to play Doom quite effectively even on a tiny screen. Now we can only hope that someone with serious design chops comes and transforms this fledgling tech into a smartwatch that actually looks good.
