Just an update: I finally wrote the firmware for doing chorded typing on my keyboard. I typed my first "the quick brown fox jumps over the lazy dog" in VeloType today at around 2WPM.

I still have a ways to go before I reach 200WPM...

The hardware is finished, I'm using it full time now, just as a regular keyboard instead of a chording one.

I'm going to start writing chording firmware using the Velotype layout very soon. I ran a whole bunch of language research scripts and got tons of data and used that to design some new ...

@Squeaky I can't actually do that because I'm using the Teensy 3.1, which can't run any of the existing keyboard firmwares. Also Plover is designed for dictionary based phonetic layouts whereas Velotype doesn't need a dictionary so it's a totally different architecture. Thanks for the suggestion ...

I just wrote up a build log with more info about my keyboard: http://thume.ca/2014/09/08/creating-a-keyboard-1-hardware/

@xman You should never have to press more than 2 keys with one finger on any decent chording layout, in fact on the Velotype layout theoretically you never have to press ...

Here's a fixed link http://www.infinitytraditional.com/infinity-ergonomic-student/ , they updated their website since I last posted.

The thing about modding an ergodox is that it doesn't necessarily have the right arrangement. You might get by with just modifying the switches and then maybe adding ...

Plate mounted keyboards aren't too expensive, so I wonder how much it would cost to build one of these http://infinitytraditional.com/ProductdetailsV1.aspx?ID=15. Yes, I agree maybe not a logical conclusion.


I think in order to make a nice lever based design the levers would have to be made out ...

The model I like is based on A minimum chord stenograph keyboard for blind and sighted users by Hu, Zhongzhi. The layout presented in the paper takes comparably less time to learn than qwerty or steno (he makes the comparison in the paper). One of the subjects reached 59 WPM (295 characters/minute ...

Hmm. Unfortunately I hate hate hate autocomplete. :-)

Can you share details about your chord/layout design though?

At the moment I only have a bunch of modelling programs that run on word frequency data. I have one that does a full finger allocation simulation of the Velotype layout, and a few ...

@jacobolus only 3 keys per finger (5 for index) are actually used for chording, the rest are just extra since my switch bag had 110 switches and so that I could also use it as a normal keyboard.

I also just did some simulations and came up with a simple autocomplete-based chording model that gets ...

That Velotype page says “Very light touch! Only 15 grams per key.” — what kind of switches are they using? €1500 is a bit too steep for me to buy one to find out.

I've talked to the guys who make it a bit. They use silicone dome switches with a custom sheet and PCB. The steep price is part of the ...

If you are looking for something easy to learn I suggest you check out the Velotype ( http://velotype.com/en/ ) system instead. It doesn't allow you to type quite as fast as steno but it is much easier to learn and doesn't require a dictionary.

Also chording keyboards require lighter key activation ...
