This is just something I have been working on.  I am only using a webcamera to capture my hand movements using google mediapipe https://google.github.io/mediapipe/solutions/hands
It is obviously not production capable but I hope so in the future.  This is just a quick and little bit sloppy demo video.  Only one hand is working to animate the character but both hands are tracked and will be used eventually.  My biggest problem is the jitter you see in the fingers.  I am not sure how to resolve this or if it is even possible.  Most likely I will have to wait for a new release from mediapipe with a smoothing affect.
