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!

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.
