Sensors output a lot of data. Kinects, Leap Motions, and touchscreens all output a wide range of data and tracking regions. The reality of our industry is that we often only need a small region of interest within that larger sensor space. This may seem complicated at first, but there are some easy ways of approaching it using some of the standard tools you have available to you in TouchDesigner. This includes finding calibration ranges with Trail CHOPs and Analyze CHOPs, normalization with Math CHOPs, and clamping with Limit CHOPs. With these few techniques you’ll be able to quickly and easily calibrate your sensor data to track a portion of your sensor data in TouchDesigner.
