I don't know of others that do this at this time. I didn't actually do any research. It is something that I wanted for myself and the way that I like to work. I prefer to hand write as much as possible. I was trying out a Surface Book just because I could hand write my e-mails!

It is working pretty well for me. I used OpenAI and basically started asking my friends to hand write samples for the NN to learn from. They write them various levels of neatness and various slants, font size, etc. I store the handwriting strokes as a series of points and convert to digital text when they are ready. I save the handwriting along side the digital version. It is possible to hand write, then come back days later and your work is still there. Maybe I could make a video to show if it is useful.
