This is a simpler version of Twiddler: https://twiddler.tekgear.com/

Have you ever used that? It looks interesting.

I used twiddler 2 (I think). It was cheaply made chorded keyboard. I admit I did hold down the keys rather hard while learning to use it. Soon after I'd learned the patterns the keys started breaking. I took it apart to take a look, all the keys were connected by tiny bridges of plastic. When the plastic bridges broke the keys became loose and non-functional.

This is called a chorded keyboard [1]. Like seemingly everything invented in the following 40 years, it was introduced by Douglas Englebart in the Mother of all Demos in 1968. Englebart had a iOS app that allowed you to chord type as well. 1. https://en.wikipedia.org/wiki/Chorded_keyboard

I'm sure I remember an Asimov story where a reporter is hiding one of these in his pocket and taking notes unobtrusively, hoping nobody will notice the small hand movements.

These were around as far back as the 80s IIRC - and when I was at Intel in the late 90s - there were stories of this one engineer, who would a recumbent bike down San Thomas Expressway to the SC campus, and he had chorded keyboard he made attached to the handles on his bike - and the legend was that he had a sat phone on his bike and he would code on his way into Intel while just keeping track of everything he typed in his head. He didnt have a display...

There were also some pants in the early 90s that had some of these built into the thighs of the pants.. so you could type with your arms basically at rest on your lap or at your side.

A friend of mine made this keyboard a while back https://github.com/TristanTrim/asetniop-keyboard

I have that one starred. ASETNIOP looks quite interesting to me. I just wish it was open source. Without that, I don't see how I could possibly adapt it to the various operating systems I use day-to-day.

It seems like every hardware geek makes one of these at some point. I think it's really cool. Designing a chording scheme for individual keys is a fun problem, kind of a nerd snipe. But in the end everyone concludes, "It's too slow to be useful." I think where the hand held keyboard might be really interesting is in combination with steno ( http://www.openstenoproject.org/plover/ ), but I haven't seen that done.

It seems that handwriting is 24 WPM. It would be neat to get that input speed on a computer using one hand without much more exertion, and choosing letters from a menu seems like more exertion.

Falsehoods programmers believe about hands: - they have 5 fingers Joking aside, that's a really nice project: congratulations!

Well, digits; a thumb is not technically a finger:)

Technically words can have more than one meaning.

https://en.wikipedia.org/wiki/Thumb#Thumb_and_fingers

Colloquially, for many (most?) English speakers, the thumb is a finger:

A strawberry is a berry. I don't care if biologists or botanists or whoever use a narrower technical definition in their research papers. The colloquial definition is just as valid. Prescriptivism-by-authority can take a hike. Yes, I will die on this hill.

Since there's a plenty of chorded keyboards already, someone should come up with some sort of a scat keyboard, or rather input method. Each keystroke is represented by a sequence of three notes that you sing into the microphone. Three notes produce two intervals which, measured in semitones, are converted into keys pressed (being, say, duodecimal digits). The relative duration of notes sang can be interpreted as modi…

You should talk to Tavis Rudd, maybe. https://youtu.be/8SkdfdXWYaI

wow this is really awesome. Actually was look at creating a novelty device for myself. Steam controllers touchpads, logitech MX's scroll wheel. ps5 haptics. Buttons with a great tactile feeling.

If anyone knows community that like building things like this, I couldn't find anything. (mainly because i have no idea if it has a name)
