Research -

Here is the background research I did when putting the keymap together
deafandblind.com   information on letter and word frequencies in English
( http://deafandblind.com/word_frequency.htm )

and, of course, because I adapted the 101-key Colemak keyboard to this 55-key keyboard,  I used this schematic:

I highly recommend you'll learn how to type with one hand on a standard keyboard. Read also: Why One Hand Typing on Standard Keyboards

The two leading one-hand typing keyboards are Frogpad and Half-QWERTY. Those are better IMO than the solution you mentioned above (although much more expensive).
Frogpad: it already has it own layout which is designed for one handed keyboards, so making a Colemak-Frogpad makes no sense.

Matias Half-QWERTY: Also a very good solution. This solution could be a software-only solution and work with existing keyboard. However, Matias are known for making legal threats for any software implementation of their idea. However since the patent claims specifically mention QWERTY/Dvorak, I think a Half-Colemak layout shouldn't infringe on the idea. Moreover in Europe there's no software patents in Europe. In any case, creating a Half-QWERTY software is a very complicated task, because it requires digging into the kernel to modify the behavior of the keyboard. This is not a project I'll be able to embark on anytime soon.

Colemak can't be well-adapted to the Wolf King Warrior solution you suggest. It requires a complete redesign of the layout optimized for one hand and Wolf King Warrior. If you want to create a new keyboard layout, I suggest using Frogpad or the one-handed Maltron keyboard as the base design for the letter positioning, which is better adapted to one hand typing.

I do agree with you, Shai, that my keymap will never be mainstream.  For a one-handed keyboard to be adopted as an International standard the key reaches would have to be aligned and discrete.  As you can see from the picture the concentric circle design  of the Wolf King Warrior keyboard the keys are not really lined up too well from circle to circle, and although it saves space, it does not make it easy to remember exact reaches by feel alone.

I doubt the Frogpad is superior because that requires pressing encumbering toggles between strokes to access a second letter set.   It is not a "true" one-hand keyboard. And the other alternative, the Maltron, is _hardly_ an aethetically pleasing alternive one-hand keyboard.
Here is a picture of the Maltron

Just looking at what they currently have available for one hand keyboard typers made my stomach turn.

Has anyone ever heard of cellphone T9en keyboards?

wtt

i could create a Half-Colemak-version of the ENTI-Key++ - System like this: www.entikey.z11.de

To make new modifier keys like a "AltSpace" (NOT "Space-CapsLock" since it doesn't lock anything and certainly not caps; I like "AltSpace" since it reminds me of "alternate realities" hehe), I think you have to hack deep down in most systems. I certainly cannot do it. If you mean moving an existing modifier to the Space key that's doable enough (through registry remapping in Windows and similar methods on other systems).

There may be a layout-based possibility though and I'm planning to look into it (on Windows only, I'm afraid) at some point: I've noticed that Swiss keyboards have an extra modifier. They use the "CapsLock" key as a fourth modifier instead of CapsLock! That's intrigueing. It seems that the Microsoft KLC app can map to this extra key, but I don't see any extra modifier positions in Unix/Linux layouts so I'm unsure how to do it there. With any luck though, those systems are so flexible that you could just specify and add as many modifiers as you like by some kind of specification with no need for "deep hacking". There's bound to be Swiss Linux users!  :)

I see now that the AHK method uses Space-on-up to resolve the dual role of modifier and space bar. Interesting concept. That couldn't be done using a layout- or register-based method so maybe the script way is the only one that'll implement this idea well without losing easy access to the vital spacebar that stands for some 20% of keypresses (on a normal layout!).

The idea of mirroring the keyboard with the extra modifier is intrigueing. But it wouldn't allow one-handed typists to type fast, since half of the most common letters would be on modified presses and therefore slow. Too bad, since it's a hella sexy idea. I almost want to learn it to see if I can get that "coffeecup/mousing layout" they're all talking about.

On a side note, I loved all the chunky-pressy button designs in that brilliant Pixar movie "The Incredibles", but I was sorely disappointed to see the "nerd keyboard" with lots of extra buttons but in QWERTY?!? A real, full-blown nerd keyboard would at the least have a left-handed programmer's Dvorak (or better! - I hadn't discovered Colemak yet at that time) to enable mousing and typing at the same time.  :)

Ok, since posting that, I have successfully migrated from Windows to Ubuntu Linux.

It's been a while since I've been on these forums, but I've been itching to know this:
What do I do to get back that one handed glory?  Is there a layout independent feature in X that can use the space key to flip the keyboard?
--and if so, please see that
backspace ~ '  and
tab ~ enter
If I see that, well, I'll be the happiest typist for 3,000 miles at least (Anchorage, AK).

skippr, we're digging back very old stuff.

I can't really give a clear cut recommendation, and it all really boils down to a matter of preference and priorities.

I just did a quick test comparing QWERTY vs Colemak for one hand typing, and there's clearly less hand distance involved with QWERTY.

I'll recap your options:

1. Frogpad: chording less than 20% of the time, small keyboard footprint, low finger distance, requires special keyboard. If would be able to type with only one hand, that would probably be my choice. Then again, I've never tried it it

2. Half-QWERTY/Colemak: chording about 50% of the time, normal keyboard, low finger distance, could be implemented in software. This would be what I'd use if I'd type most of the time with two hands, but would need to type in one hand from time to time, and I didn't want to spend too much time learning a new keyboard layout.

3. Dvorak Right hand/left hand+Sticky keys. Can use a normal keyboard. For people who don't like chording at all. Comes by default with most operating system.

4. Standard QWERTY with one hand+Sticky keys. The main advantage is that there's no need to learn a new layout, but obviously it's not optimized for one hand typing. Might be a good skill to have.

There might have been new technologies developed in the last few years, but these are the ones I know of.

Thanks for your replies guys!

Whoa! This Half-QWERTY is f--- expensive! 600 Buclks for a bunch of keys?? Anyways, that't not my main interest.

What your replies didn't focus -as it was one of my main requirements were- international accents. The Frogpad and the Half-QWERTY does not address that.

I also have another requirement -I did not address it so specifically in my first message, but now-, so I told you I am not planning on writing a book, but more of web browsing. And your recommendations only concerned on how I can type (English) text. Okay, so my other requirement is now, more specifically: KEYBOARD SHORTCUTS. Mostly for the browser.

And now. Let's look from one step further. Why do I want to type with one hand?
I guess you are all here on this forum because you want some "ergonomic" experience with computing, in some way. That's true for all of you, right?
Two handed typing: if you want to be ergonomic, and your hand to be in a natural position, you need a "natural" keyboard, like the Microsoft Natural Keyboard (cheap, but bulky), or a folding one (more expensive). For various reasons (proper hand positioning, laptop radiation), ergonomic laptop computing also requires an external keyboard, when possible. Do you think the external keyboard adds much weight to your laptop? Just think of how today's laptopss weight much less than yesteryears' versions. If you don't plan on bringing a bulky MS Natural Kayboard, your other option is the expensive folding one. Or, you can type with one hand, with a much cheaper, basic compact external keyboard for one hand typing.

Summarizing everything, for the second time: what is your best recommendation for my case, again?

I truly appreciate your feedback.

It seems the Half-QWERTY is just a hardware version of the mirrorboard I dropped a link to two posts up. What is the problem with it aside from the price? (As the mirrorboard is free. Both as in beer and speech.)
