A Viable Alternative to Typing

There are a lot of existing BCI hardware systems out there

Could you give an example/link? It never occurred to me that this might be something I could buy as of now.

Both speed and accuracy of brain-computer interface for typing are pretty bad. What your motivation for using it?

If someone is looking for something like Pentadactyl but for Chrome, I recommend Vimium. It adds tons of keyboard shortcuts that make keyboard-based browsing awesome.

What sort of hours are you logging on your keyboard these days? It looks like Mr. Egoscue has quite a catalog, could I impose on you to narrow down which books you found helpful, please? I live in South Korea, so getting a non-kindle book shipped over the ocean is a non-trivial undertaking.

Sure, but relearning how to type would be a massive investment in time. I want to try as many other solutions as I can before I dive into the Dvorak setup. BTW, can you link to the evidence that it helps with CTS?

It depends, but so far I'm definitely getting fewer words per minute than when I type. As far as strange names or made of words, it tends to do OK but there are times when you have to do a lot of proofreading. It handles technical vocabulary surprisingly well, and since I'm only using the default program that came with my computer, I'm sure that using something like dragon would work even better.

There are cameras that can tell where someone is looking, so it seems to me that one input method would be to have a keyboard where you look at the letters that you want to type.

This seems way slower than typing or speech recognition.

In Dragon you can easily enter control characters by saying "Press" or "Type" as in "Press alt", "type control alt". The same seems to be true of most keyboard alternatives out there these days, as is creating macros for frequently used phrases, commands, whatever, as you can see in the video posted by the OP. It took a while to adapt my speech to speech-recognition-friendly pronunciation (not just providing a corpus of my own pronunciation) but now the # of typos ("speechos?") doesn't seem to be outrageous.

In some cases a small set of foot pedals can also serve as keyboard alternatives for frequently-used keys like shift, control, alt.

I use foot pedals + Dragon when my hands aren't up to the job of keyboarding (a week or two every couple of months). I also found Windows SR technology to be adequate for many things but have the luxury of access to Dragon at work. For me speech input is about 85% as fast as typing in sentence/paragraph formats - although there are SR errors I find a second-pass editing process to correct such errors is more effective than the equivalent of backspacing and replacing as I would normally do with keyboarding. My speed drops to more like 40% in programming or other situations where I use a lot of copy-pasting. Could probably improve this if I had to do it all the time.

I have tried eye-tracking input methods, including remote and head-mounted kit just for fun, and it seems just too cumbersome if there are speech or hand-based input alternatives. Although to be fair I haven't tried any of these methods long enough to reach an improvement plateau.
