Engelbart's Keyboard Available For Touchscreens
An anonymous reader writes "Doug Engelbart should be known to everyone on Slashdot — he did invent the mouse after all, among many other inventions all of us rely on today. There was one more obscure device he came up with that never really took off, though. It was called the Chorded Keyboard, and consisted of a system that allowed you to type using just one hand. The key to this system was finger combinations, which allowed up to 32 different characters — more than enough for the alphabet. Now that one-handed keyboard has been ported to work with touchscreens, and it could end up being quite popular. The key benefit is the fact you can type anywhere on the screen and don't even need to see where you are typing. The only difficulty is learning all the key combos, but once you have them cold you may be able to type faster than with two hands on your smartphone or tablet." Bonus: being software-only and open-source, it's much cheaper than a Twiddler.
Wait, fellow poster! Please reconsider before you write that joke!
Just wait till the Emacs people come along... they're gonna have a gasm. Wait for all the keybindings in 3.... 2... 1....

Unless my life depended on it, I doubt I could ever train myself to use 32+ memorized "chords" to type all of the letters and numbers.
Unless my life depended upon it, I doubt I could ever train myself to use a 101+ key keyboard...

Stenotype, which is used for both court reporting and closed captioning http://en.wikipedia.org/wiki/Stenotype can typically be operated at 300WPM.
It has the advantage that you can already take classes in it, and that there are tons of people already trained to use it.
I guess Paul Wittgenstein http://en.wikipedia.org/wiki/Paul_Wittgenstein might appreciate it.

It was the quinkey or microwriter. Can remember playing with it but not for long enough to be interested.

I think the poster below is correct, it's a Microwriter AgendA. The picture at Wikipedia is of some other Microwriter device. This page has a picture of the AgendA:

My friend had one around the same time I had my Psion Organizer II, ~1989 or so in highschool in the UK.
The picture at Wikipedia is of the Microwriter, not the Microwriter AgenaA. Try this page:

There's a picture on there under that name which is the device I remember -- the AgendA that is, not the Microwriter below it.
Yes, I can see the learning curve is steep, I must be missing something, though, because lowercase letters (26), uppercase letters (26), digits (10), punctuation (26), and "meta" keys like Escape, Tab, Backspace, Delete, and enter (to name a few) exceeds the 32 chorded characters mentioned in TFA.
I've often wondered if Morse Code could be a viable option for data entry on a small screen. Admittedly, there are some punctuation and capitalization issues with this, as well. Yet, it WOULD permit one to text while not requiring one to keep their gaze on the screen.
I suppose one could split the screen in half (e.g. left/right) to distinguish lowercase from uppercase and to allow additional symbols to be defined. I doubt I'm the first to think of this, but I've not seen anything like this being available, I thought I'd toss it out for consideration and discussion.
I don't think it'd be that hard to learn a chorded keyboard, but I've never tried so I'm not sure. However, there is a big difference between those and regular keyboards: with a regular keyboard, if you touch type, you're relying on positional memory. Every key is in a particular place, and never moves. Chorded keyboards don't have this; you get different characters through different motions of the keys, and you have to move multiple keys at once for each different character. Maybe it's not so easy.
That said, I don't see how this keyboard can possibly work if it only has 32 combinations, unless there's some extra modifier keys that you use with the other hand or something. Between lower-case, upper-case, numerals, special characters, and others (F-keys, insert/delete/home/etc.), you need a minimum of 84 keys to replace a standard 101-key keyboard, and a couple more if you want those stupid Windows keys.
Ha! With my typing system, I needn't use more than just one finger!
PS: any advice on getting first post? It seems impossible.
(or what joke were you referring to?)
I read "Twiddler" and it makes me think The Batman has been reduced from stalking Master Criminals to now pursuing Masturbaters...

I remember, long ago, when the guy first brought out this keyset. Some University, MIT as I recall but that may be wrong, tested the learning curve with two groups of people. One learning typewriter type touch typing and the other doing the same exercises and investing the same number of hours on this thing. At the end the "chorded keyset" students tested almost twice the speed with approx. the same error rate. Supposedly a few "freaks" were able to type two different documents at the same time using both hands.
They were sold for a few years. I always wanted to get one but never seemed to have the time.
In the early 90's I remember reading that the military tested a modification of the idea that used a wrist strap with sensors to detect the movements of the fingers without actually using a keyboard. The idea was that astronauts in zero-G and pilots under high G could use it.
Seems like that could be a terrific solution for tablets and desktops alike. Make the wrist strap wireless and away you go.
Since it is very common to hold a tablet with one hand, it would be interesting if someone would build a tablet with pressure senors on the back and side (for your thumb) so that the hand holding the tablet could type just be squeezing. Make the entire back of the tablet pressure sensitive so you don't have to worry about lining your fingers up, just let the software figure out which finger is which based on the relative location of each press/squeeze.

I deeply desire to have a Symbolics machine of my own some day—or at least a version of OpenGenera that boots properly.
You won't have one properly licensed, since the courts were unable to agree who owns the copyrights to Genera. On the other hand, that means you cannot be sued by the copyright holders, since nobody is quite sure who the copyright holders are.
You'll need:
Setting it up requires a little bit of work (you'll need to set up a local NFS server and to tweak your X server's modifier mappings), but I warmly recommend it -- it's complete enough to do some real work in Emacs, and the full sources and documentation are there for your greater enjoyment.
