LightGuide: Using On-Body Projection to Guide 3D MovementMay 6, 2012
This is some fun work out of Microsoft Research that looks at using projection on your body to guide your movement in 3D space. If you want to figure out how to play sports, an instrument, exercise, or anything else that requires movement, they show that projecting visual hints directly on your body can help! They use a single overhead projector and Kinect to project hints on your hand. Their results show that when users tried their hints, they performed movements more accurately than by just using video.
