WristWhirl (IMAGE) Dartmouth College Caption Checking email, tracking fitness, and listening to music, are just a few things that a smartwatch can do but what if your hands aren't free? A Dartmouth-led team has come up with a solution by developing WristWhirl -- a smartwatch prototype that uses the wrist wearing the watch as an always-available joystick to perform common touch screen gestures with one-handed continuous input.
