Thanks so much! Answering your great qs:

1) I still have the waving your fingers stage (it's after the screenpalm), but it now walks you through different finger motions so that the results are more consistent than waving your fingers all around. It's detecting then angle of motion, but I'm so far only using this for building the 3D hand model. The old method had better UX and fewer bugs, but the new one will more accurately measure the size of your hand.

2) I've never thought of that! I sometimes generate symmetrical keyboards for myself, simply because it’s easier to edit when both sides are synced. But I ultimately think it’s better to fit each hand independently.

3) The cygnus keyboard is super cool. I’ve made one and modified the STEP file to change the sockets. The fusion 360 files for it are published, so it likely has some parametrization but not anywhere close enough to achieve the flexibility of the Cosmos model.

There’s a tradeoff between customizability and how perfect the keyboard looks and feels. I’ve opted to go all-in on customizability, because to my knowledge no other keyboard design does this. I make as few assumptions about your keyboard as I can, so that Cosmos works with a single key, small mouse-like modules with a trackpad/ball and a few keys, or a proper keyboard shape. The downside is that what I’m doing is akin to teaching a robot to paint, whereas I’d compare designs like the Cygnus that place more constraints on the keyboard shape to a human painting. Until AI becomes sufficiently skilled at 3D design, the human painting will be more creative and skilled than the robot, and I can't bridge both types of design.
