Monday night towards the end of my class, I had the pleasure of listening to Dr. Swanshy talk about using Google Cardboard and Leap Motion. The Leap Motion Controller lets you use your computer in a whole new way. Reach out and swipe, grab, pinch, or punch your way through the digital world. Leap Motion works with both Mac and PC and will be on chrome books in the future. The Periscope video below shows Dr. Swanshy along with my classmates using Leap on his Macbook Air.
If you are into Makerspaces or Gesture Theory, I highly recommend this awesome tool.
