tractyl-manuform-keyboard VS ErgoWarp

This keyboard is an attempt to make a best-of-both-worlds combination between the modular (and support-saving) design of dereknheiley's compactyl manuform (with adjustable wrist rest mounts) and the trackball-enabled design of the noahprince22's tracktyl manuform, forking the firmware from Schievel1's dactyl_manuform_r_track.

The tractyl manuform from noahprince22 outputs a model with a test hand with the finger length input from base to knuckle to knuckle to tip. I've found it gives a pretty decent first impression of the alignment of the dactyl in your hand. To get it just you do need some iterations with a test model

https://github.com/noahprince22/tractyl-manuform-keyboard this one does, its quite different from a lot of other manuforms, so it might be worth just using the code that generates the slots for the daily sockets and adding to a variant you like

So, I followed this guide to build my next keyboard. The only difference between mine and this one is that I added an encoder to the right side, and I used 2 Elite-c instead of 2 Pro Micro.

I wrote a build guide for mine here https://github.com/noahprince22/tractyl-manuform-keyboard. Basically just some ball bearings. It's less frictiony than the Logitech trackball I tested in best buy.

A Dactyl handles some of the press angle, and splay is the term to describe pinky (and other fingers) outward motion angles on the horizontal plane. I have yet to see a keyboard implement both besides the really interesting ErgoWarp. https://github.com/pseudoku/ErgoWarp/blob/master/Photo/Proto6.jpg

The ErgoWarp has an arch in the x-direction.

I am intrigued by the thoughtfulness behind https://github.com/pseudoku/ErgoWarp. Like, enough that I'm tempted to build one. But it looks like a PITA to build, and even more so to get used to, and project looks dead... Has anyone tried one and would you share your experience?

The ErgoWarp has finger joint lengths as parameters. But it seems to me to be numerically fragile, and even after being based on hand measurements and some kind of fancy interpolation, it still has a section for tweaks. That means the fancy math isn't quite good enough to directly generate a perfect keyboard!

The ErgoWarp has a slight negative horizontal curvature. It's also the only one I've seen where you shave down your keyswitches and keycaps so you can fit more. I want to explore that.

This diagram would place the ErgoWrap on the seabed.

https://github.com/pseudoku/ErgoWarp probably, but this project looks to be dead.
