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)."

It would also help if there was a standard for chorded data entry.

Circa 1989, so patent worries should be minimal!
Why the Qwerty exists (Score:4, Informative)
The reason qwerty was adopted as a standard was not for efficiency, but because kingpin (at the time) IBM decided that when electronic buffers were introduced to typewriters and there was no longer a need to obscure keys on the keyboard in order to prevent mechanical jams, a keyboard layout they were currently producing would become the standard.
Since then, every typing class, every default layout and the vast majority of keyboards have been based upon the qwerty layout.
While some people on the bleeding edge of technology are willing to learn something new (I personally am proficient on Dvorak, Palm Graffiti, phone texting, and blackberry) A real standard of input will arise when the device is both similar to the qwerty equivalent and small enough to take along in your pocket. The average users are more willing to learn something slightly different than new altogether.
Chords are used all the time for subtitling (Score:3, Informative)
Those operators use chording keyboard (though with more than 5 keys), set up so that particular key chords map to common phrases. Typing this way is a lot faster than typing on a conventional keyboard, but it obviously is a lot of effort to learn.
So yes, it does work.

I worked with blind and partially sighted kids who use 5 finger keyboards. They use a 'chord' system, like a guitar or piano.
The chords kinda look like the letter you are spelling, so to create a J you would hold the keys that kinda make that shape, I forget the exact sequence, but it was pretty easy to use.
But, the 5 finger keyboard was used like a regular keyboard, it was placed on a desk. I dunno how this would work if you had to hold it at the same time. Much harder I'd imagine.

Q codes [flashwebhost.com], internationally recognized 3 letter codes beginning with the letter Q. Used in the Ham community, but there are Q codes for aeronautical, nautical, etc. use as well. It is possible to hold a meaningful conversation with someone, regardless of what language you speak.

You'll notice they have long nails on the right hand for strumming and picking, and shortened nails on the left so they don't get in the way.

Evidence that learning/benefit ratio is too low (Score:3, Informative)
The stenotype machine was, invented in 1830 [wikipedia.org], still in production, and still in use by court reporters who can attain up to 300 wpm with it. In contrast, the record sustained typing speed for a Dvorak typist is 150 wpm [wikipedia.org].
The fact that stenotype machines have been around for well over a century and that nobody but court reporters use them... and that when Doug Engelbart and his group invented the mouse, it was only intended to be used only in conjunction with a chording keyboard... and the fact that most modern keyboards actually allow a form of chording (shift, control, alt, and a letter) but there are no common hacks to use this to increase typing speed... strongly suggest to me that the learning/benefit ratio is way too low for any scheme of this kind to be adopted.
If I recall correctly there was a glove-like chording keyboard marketed a few years ago, whose designers had even devised a clever chording scheme in which the fingers you used sorta-kinda had a relationship to the shape of the letter, and a number of reviewers praised it and said they were able to achieve facility with it in a week or so. It obviously didn't take the world by storm.
