Question I need help with project information with unity, vuforia and gesture recognition

I'm doing a project where I integrate unity, vuforia with gesture recognition; I also do the integration of a home automation environment using a raspberry as a server. My problem is that I can't find solid information for gesture recognition, which is capable of recognizing a sign language with unity. I was thinking of integrating python with unity, but there is no solid information, and in this way I can integrate a solid and stable gesture recognition. I would like you to help with some additional information.
