Single-handed, Offline, Portable Data Input?

One Armed Bandit asks: "By now everyone knows the available single handed keyboard alternatives. What I've not seen available is a true portable one-handed offline input device. Gary Friedman's final concept for the DataEgg is a fantastic one. Unfortunately, it never made it to the market. I - for one - would pay a premium for this kind of device. I think one of the reasons that this hasn't been built is because of the requirement for users to learn a new input mechanism. In my experience, this is a more difficult perception to overcome than a skill to acquire. How many of you can navigate your various electronic devices by touch? Is anything on the market? Does anyone have a pet project?"

"The high points would be:

• Single handed operation (probably chorded)
• Local file storage
• On-board display for visual feedback and document review
• Uplink to host (USB, IR, Wireless)

I can't count the occasions which I'm walking down a noisy street (hence no voice recognition) and dying to jot down my stream of consciousness (without using two hands for a stylus and walking in front of a bus)? I would kill for something like this!"

There would be more of them but . . .

Cell phone with noise cancelling headset.

Even in a noisy environment, you can take audible notes if you have a nose cancelling headset. With the exception of car horns, the traffic can't be heard. However, you also look like a homeless person jabbering to invisible people even more than the usual headphone+cell phone geek, because the normal cell phone pattern of speaking goes away. Nothing like randomly beginning to speak into the air to freak the locals out...

I don't know. I happen to like PEN AND PAPER.

Handykey

Handykey, in New York, used to make a device that was both a keyboard and mouse. I got mine about 3 years ago, it had DOS drivers and they apparently came out with Windows and PS/2 drivers later. Plugs into the serial port for data, the keyboard port for power (only drew 9 mA or so.) It's chord based, most characters are two fingers, with the modifiers on the thumb; it had a velcro strap to wrap around the back of your hand to hold it in place.

There used to be a FAQ about such keyboards; look at any of the RSI resources. Also look at the pages about the "Behemoth" nee' "Winnebiko" project, they used the one of the "bat" keyboard sticks.

You might also look at some of the one-handed layouts for conventional typewriters that Dvorak came up with, along with the more well known layout. It depends on what you're trying to do...

ASCII chording keyboards

[rqqrtnb]

I remember from the early days of microcomputers, when real programmers used toggle switches and keyboards were outrageously expensive, there was a one-handed ASCII keyboard. It was a sphere with four finger buttons and eight thumb buttons. One was supposed to play a chord with the fingers, giving eight bits, and then press one of the thumb buttons, giving three more. It was attractive to a lot of people because the small number of moving parts made it cheap. You might be able to find one used. It would take a lot of training to use, and it might be very hard to get any amount of speed, but it's worth investigating.

There was a commercially-produced keyboard of this form, known as the MicroWriter. It was - probably still is - quite popular among blind/disabled/special-needs users, though that was not its primary market.

First incarnation was a hand-sized device with 6 keys (only the thumb had to move) with about 8K of RAM and an 1802 processor. It was intended for use as a portable word-processor. The same mechanics and case were used as an auxiliary keyboard for the BBC Micro (using a resistor network on the switches, fed to an analogue input port on the micro).
