I've been working on a couple of chording keyboard designs and was thinking I might be able to create a virtual keyboard using this library. It would be nice to also be able to recognize the hand from the back. A keyboard would also obviously be necessary to track two hands at a time.

How does the application deal with different skin-tones?

That's an interesting idea. I have not tried to build something similar but a humble word of caution that I want to put out is that no matter what kind of ML you use the mechanical version of the instrument will always be more precise (you likely are aware of it, just want to make sure). However, you might be able to approximate precision of the mechanical version.

Two hand support would be nice and I would love to add it in the future.

The engine should work well with different skin tones as the training data was collected from a set of many and diverse individuals. The training data will also grow further over time making it more and more robust.

Similar thought here. I'd like to track two hands above a real keyboard (size/position established via 2 X QR stickers) to feed into a VR piano training simulation.

The tech is all there, really it's just having the time and effort to get all the pieces together!
