Smartwatches are awesome. They’re growing in popularity. We can check the weather, select or create custom watch faces, keep track of our heart rate and step count, verbally take notes and share those notes with other applications… We can even check the time with them!

The problem with smart watches, though (aside from Pebble watches) is  that with a touch screen, your finger tends to smudge the screen, and even get in the way of what you’re seeing. Face it, your finger is hardly any smaller than the tiny screen on your wrist.

In the following video, people from Carnegie Mellon University are working on adding additional input types to touchscreen smart watches; mechanical pan, twist, tilt, and click.
