Try the CLP model.

Yeah, came to same conclusion, but with a twist.. no upper case slots needed.

Just another toggle on thumb for CAPS.

So that helps reduce the key count considerably.

Get a mouse with many buttons. Assign them meta and editing actions that replaces any ctrl- stuff. copy, paste, select all, save, back, etc.

Am considering it. Problem is my usual online stores take a week or two to deliver (no next-day Amazon-style here AFAIK)
This cast is supposed to come off on 30th and be replaced with modern design and at that point they'll probably want me using my fingers as much as possible (to ensure tendons etc don't get too attached to the steel plates). So may end up NEEDING fancy mouse for only few days. Am going back to my trackball :-)

Speaking of mouse, using one on my right hand again is damaging indicated spot on attached, Years ago when I used mouse I put blanket on table then covered it with sheet, and that was my desk/mousepad. Suppose that protected my hand. Sheet gave nice solid colour for mouse laser to measure on, blanket provided padding.

Try the CLP model. Since it optimizes lowest amount of movement. But you need great locations for the modifier keys on the thumbs. Obviously ANSI/ISO will not work at all. (we all know that that form factor is just crap for advanced keyboard design anyway.) Split keyboard may be better, since you just need one half.

So yeah, Ansi 104 sucks even more for one hand than for two.

As such, both one-handed Dvorak layouts are pointless wastes of time... the form factor is completely wrong.

For right-hand use, the lack of alt-tab on right is particularly annoying, as is the constant switching between mouse and keyboard. At least the right-hand copy/paste operations are more comfortable than ctrl-xcv would be, but ctrl-a is awkward.

Maybe need better mouse with more buttons that I can assign to such things.

As far as keyboard goes, it feels like something like my mobile layouts (eg Z8 here http://keyboard-design.com/swiping.html) are what is needed but I have some issues with my own layouts that annoy me. (in particular, the M, and distance between Y and OU).

So started with a mockup on KLE, still lots to do. Am thinking of main block with letters and 4 puncs, then shift layer, then two more layers, one numeric, one punc. Not sure about navigation yet.

Will advise any progress or bright ideas.

Oh yeah, having ctrl-Q and ctrl-W next to each other is NOT GOOD.

Must maybe pick my surgeon and physiotherapist's brains about market for one-handed layouts... such users probably less pedantic than most about qwerty and maybe medical aid does not freak about price....

Sorry to hear that.

Are you now gonna devise the perfect one hand layout? For that, I suggest sticky modifiers--so you don't have to hold down shifts, which would demand dexterity.

I did wonder if the universe was pointing me in that direction.

More worryingly so because a few days ago I had been thinking about one-handed layouts for some reason ... but more along the lines of "I'm glad I don't need to work like that" .... and now here I am doing that...

I'll see if the universe throws any bright ideas my way over the next few weeks....

Cheers, Ian

smashed my left wrist. back on ansi keyboard and mouse on right hand and mostly one handed typing for now. At least it has mech switches (gateron red I think)

Stumbled across this:

http://www.musanim.com/mam/qhkcstfpn.html

Tried playing around with it but requirement of having vowels and liquids on home row works at odds with putting common letters on home row. T, N and D can easily be put in better (but not optimal) spots.
Also have H and E on same finger is never going to work.

Came to the conclusion that it may be comfortable for the mind, but we type with fingers not brainwaves, so comfortable for fingers is more important.

Colemak 82.48
MTGap 93.05
Capewell 128.75
Klausler 181.35
Dvorak 196.04
Dangvu 204.9
Workman 212.57
QGMLWY 350.73
Norman 503.58
QWERTY 525.73


Voice in my head was still complaining... something about finger usage.... so I did a quick experiment, and multiplied each letter pair on same finger by a weighting per finger (simplified model: thumb = 1, pinky = 5).

Overall resulting order was sorta the same, but some differences, here's the revised list:


Colemak 210.78
MTGap 264.3
Capewell 377.79
Klausler 440.98
Dangvu 482.96
Dvorak 523.69
Workman 567.26
QGMLWY 802.54
QWERTY 1426.34
Norman 1446.09


Which is not bad, and except for QGMLWY, compares order-wise with the same-finger list (here in reverse order) on https://normanlayout.info/compare.html


    Norman: 4.7%
    QWERTY: 4.6%
    Minimak: 3.1%
    Asset: 2.6%
    Workman: 2.4%
    Dvorak: 2.2%
    Klausler: 1.6%
    Capewell: 1.4%
    Arensito: 1.3%
    Colemak: 1.3%
    QGMLWY: 1.3%


Norman is known to have bad same-finger metric.
I assume QGMLWY is out of order for me because of the finger weighting.
It's score was calculated thus: (first digit is KLA finger number)

1 => 'qdz': 0.42
2 => 'gsx': 20.0084
3 => 'mtc': 94.0185
4 => 'lwnrvj': 111.011
5 => ' ': 0
6 => '': 0
7 => 'yfiakp': 447.6328
8 => 'ue': 31.4118
9 => 'bo': 98.0376
10 => 'h': 0
11 => '': 0

Cheers, Ian

Numpad revisited. Prioritize 1, 0 at the strongest fingers.
