The Leap Motion Controller can be used as an input device to TouchDesigner.
The Leap Motion controller tracks hands and fingers in an area directly above the device. It offers low latency, precise tracking and recognizes a number of motions and gestures. The gestures are provided to TouchDesigner through the Leap Motion SDK. TouchDesigner's Leap Motion support will be extended as more features and improvements are added to the device's SDK.
