This is a delightful project. Congratulations on shipping it! I would be curious to see ways to do this where the piece of paper had lines so you could visually see on the paper which key was which. Doing this would be tricky, though. On first thought, an object detection model that detects each key from a perspective, then saves the coordinates, may work. Then you would calculate the Intersection over Union between the finger annd each region. This may only work with a top-down perspective, which might be less practical in real-world use. In any case, I always miss my keyboard when I am traveling. A project like this feels a lot more practical than the “portable” travel keyboards.
