Five Finger Keyboards 177
Tijaska writes "Mobile devices are becoming more capable all the time, but their small screens and keyboards limit their usefulness. This article shows ways in which five buttons located on the edges of a mobile could be used in combinations to generate 325 or many more different characters, making a full-sized keyboard unnecessary. If that sounds like a tall story, remember the case of the retired 93 year old telegraph operator who used a Morse key to send a text message faster than a teenager could send it via mobile phone (see here)."

As my friends slowly pick up PDA phones without "real" keyboards, they've also mimicked my thumbnail mod and found they can type incredibly fast, especially with the faster processor PDAs (HTC Trinity is what I use) which offer almost no delay when typing. Disable any sound response, and you can type even faster.
I'm sure that the iPhone will make huge leaps in efficiency, but I'm happy with where I am with the "old fashioned" touchscreen typing. I've blogged, read and written on slashdot, and posted to forums from my tiny 320x240 screen, all because of a simple thumbnail mod.
Try it -- it may save you quite a bit of time, and not cause you to have to learn some new fandangled invention.
1968: Engelbart shows chord keyboard (Score:5, Interesting)
These single hand keyboards are called chord keyboards [wikipedia.org] and a pretty old idea. In fact Douglas Engelbart used on during the mother of all demos [stanford.edu] (first: windows, mouse, internet, video conferencing etc.)
I wanted one since I saw one for the first time in a computer magazine (the Octima, about 1984), but they never caught on. Some are available, mostly for disabled people, and they are very expensive. According to people who have worked with them it just takes just a couple of days to become fast on these ones, but you cannot become as fast as a very fast typist.
I guess this is the main problem: for starters they seem to be harder, since they cannot see the letters, for pro-typists/programmers they do not offer enough gain, unless they have RSI. Maybe mobile typing will finally be their breakthrough. Took only 30 years.

Had a clerk who was unable to type with both hands bring in one of her own. She did just fine in a demanding, fast paced environment (ER Patient Registration).
For what it's worth, I could never get the hang of it. Would certainly take some time to learn. Perhaps as much time (if not more) than learning an alternate full sized KB layout.
Morse-to-text keyboard driver? (Score:3, Interesting)
I wonder if there's a Morse-to-text keyboard driver for my phone? A lot of time is wasted looking to see what three keys my fat thumb is pressing this particular time. If I could just hammer away messages on one key, without needing to watch what I was typing, that would seem to be quicker...

I would be interested in something like that too, since I already know Morse code. I learned that to use with ham radio, although I have not used it very much. I don't know about any specific drivers for any particular cell phone, but here are a couple of links that mention people using Morse Code with a cellphone. It seems to me that someone could probably send CW with something smaller than a traditional telegraph key. I believe there was also once a discussion on Slashdot about that too, but I don't have time to look for the link.

And while I'm up here on my soapbox: it's just NOT that hard to learn to chord. Some people declare confidently that the learning curve is the barrier to widespread adoption of chording but it's not. Learning to chord, at least on my prototypes, was way easier than learning to touch type on a qwerty --- at which latter I never succeeded. You don't need such complex schemes as the blogger writes about.
The real barrier, IMHO, has been the lack of motivation. Why learn ANY efficient new way to type unless you are sufficiently rewarded? The reward is (or will be) mobility. Not just mobility for exchanging cryptic little text messages but mobility for the full range of desktop functionality.
