    First, love these kinds of projects – albeit that digital keys gets too much attention, where are the tongue and teeth retainer input devices hiding (which would work with arpeggios ).

    Second: I have the childhood musical training for them yet still have a problem; available time is finite – new input devices takes training; training is boring; I don’t want to spend my limited time doing boring things.

    It’s more fun learning a new music instrument than it is a new input method. I think Mythbusters confirmed that in a dream I had. Why is it more fun? The n:th time doing scales then relearning Für Elise on a new instrument is still grinding teeth with muscle strain. It i still better than what, typera.tk? <.. that needs fixing.

    Looping back to your keyboard, tried splitting and putting in the pockets of your pants or on your thighs? would help in AR/VR and does not compete with the touch-input/keyboard-input posture and ergonomics.

      The obvious downside is that you’re submitting twice as many inputs as you would be on a chording keyboard… sort of. Typing two letters requires four keypresses, instead of two chordpresses, but you can usually begin pressing the next key before you finish pressing the previous key. Meanwhile, a chording keyboard requires you to release all keys before you can begin typing the next chord, so entering two letters on a chording keyboard is sort of four “input events” as well: keydown, keyup, keydown, keyup.

      Do I smell pipelining concurrency for typists? 😏

        Just the other day, I was wondering how practical a chorded-typed keyboard with sequential input would be. Cool project, thanks for sharing!

          This is a great read, I quite enjoyed it. I would really like some gadget that I could put on my phone to type without having to move my fingers at all so I’ve been into progressively smaller keyboards.

          In fact, the way I input languages is using a limited form or arpeggio keyboards - compose keys, which function as an apreggio between (shift +) the character I wanna type + the modifier I want to add. I found it works well and I prefer it over the macOS way of longpressing a key and typing a number because that holds up every input quite a bit.

            This is pretty cool. I was recently thinking of alternative keyboard inputs. Mostly so if I wanted to code on my phone I can, but also hold it landscape in a comfortable position. I was thinking of a keyboard on the back of the phone. This is very close to what I had in mind, definitely going to follow this. Maybe modify it with some extra keys for coding purposes.

              This is a really interesting project! It boggles my mind to think how I would use this to type though.

              What do people use chording keyboards for in practice?

                Stenography, mostly.

                Fun to see the Twiddler mentioned – I used one a couple decades ago! The Twiddler was connected to a computer being carried, but now the Twiddler and computer could be a single hand held device: a smartphone could be strapped to your hand with a matrix of keys on the side.
