Interesting concept.
Some criticisms (I’m not trying to tear you down; hope this doesn’t come across as excessive negativity, as I think experimenting is great):
- If you want to use those shift keys as shift, it’s going to be pretty unpleasant IMO; right shift in particular is really hard to reach (there’s a reason the HHKB Pro doesn’t have keys in the corners)
- Right hand alt and ctrl are pretty hard to reach
- backslash is even slightly harder to reach than on a standard board, where it’s already really far
- If you use a standard set of sculpted keycaps, backtick, enter, and alt are going to be mismatched
- Enormous 6.25u spacebar is a big waste of valuable thumb real estate
A few things I like:
- Left side Alt and ctrl are in okay spots
- Enter is better than an ISO enter and maybe slightly better than ANSI enter (though those have the advantage of putting enter at the far right side of the main key block, which helps with locating it)
- Escape is much better than a normal ANSI board (the kind that include F keys)
The reason I went non-staggered for most of the keyboard is because I've seen a lot of talking about how it's more ergonomic and makes more sense for typing
I don’t personally think straight one-piece matrix layouts are very “ergonomic”; they make a few letter keys marginally easier to reach and a few letter keys marginally harder to reach than a standard row stagger, but the hands are held in basically the same position and orientation either way, and most of the finger motions are pretty similar, causing all the same issues. In other words, I think both standard and standard-ish “matrix” boards are pretty bad. Unfortunately, learning a matrix layout (coming from past QWERTY/ANSI/IBM layout experience) is just as hard as learning some other better layout, so switching gets you the cost of a tough learning curve without much benefit in terms of typing speed, accuracy, or comfort, IMO.
Things that would IMO be improvements:
- add a bunch of space between G and H and maybe stick some more keys there for the index fingers to press
- split the keyboard in half, rotate the halves inward and "tent" them
- split the spacebar in multiple parts and try to end up with 6–8 usable thumb keys instead of the ~3 on a standard keyboard
- eliminate harder to reach keys and move them to a different position or new layer (e.g. scrap the number row and put numbers and symbols on layers)
- switch away from QWERTY to something better
- make the keyboard a bit more symmetrical (right now you have 2 columns more on the right than on the left)
