I hope you help me. In my proiect I use a Kinect Xbox 360 and I want add in my application this action: recognize my index and my thumb and when I move the thumb do something, for example generate and shoot a 3d ball.
If you can link to me tutorial or documentation about my problem.
Nuitrack supports gesture recognition and hand tracking. You can find more information about the Nuitrack Hand Tracker module and Nuitrack Gesture Recognizer module in our docs: Hand Tracker, Gesture Recognizer.
Nuitrack has no finger tracking module (finger tracking is in our roadmap, but so far without an exact implementation date).
