Playtime Computing System

The Playtime Computing System is a technological platform that computationally models a blended reality interactive and collaborative media experience that takes place both on-screen and in the real world as a continuous space. On-screen audio-visual media (e.g., portraying virtual environments and characters — story world, etc.) have an extended presence into the physical environment using digital projectors, robotics, real-time behavior capture, and tangible interfaces. Player behavior is tracked using 3D motion capture as well as other sensors such as cameras and audio inputs. // “Playtime Computing,” MIT Media Lab Personal Robots Group

I can think of some AR applications for magic. How about 3D sigils drawn in places for people to see with their AR viewers? Or a mantra that plays on location? Entities positioned at four quarters? Listing/linking magical correspondences for colors or objects in view? Ley line visualization?

What else?
