Augmented reality project adds a little road system to your living room floor

Judith Amores Fernandez, Anna Fusté Lleixà, and Jam3 created the Invisible Highway at Google Creative Lab using Unity, Tango, and the AdaBox maker kit from Adafruit.

From the YouTube description:

Invisible Highway is an experiment in controlling physical things in the real world by drawing in Augmented Reality. Simply make a pathway along the floor on your phone and the robot car will follow that path on the actual floor in your room. A custom highway with scenery is generated along the path to make the robots a little more scenic on your phone screen.
