Hi everyone šŸ‘‹ My name is Helder and I'm an independent HCI researcher from Brazil. One of the two main areas I focus on is discrete input optimization (keyboard-first interaction and optimized text-entry for assistive devices, VR, and things with few buttons/actuators). The other area of focus is end-user programming, which grew from the first. My main personal project is called Keykapp, a "visual interactive predictive concatenative programming" interface I'll spare you from rambling on too much about right now, except to say that it's a bit like command palettes and smartphone virtual keyboards had a weirdo Turing-complete baby :) I've seen some really cool visual concatenative programming things on the archives, and I'd love to talk more with anyone who's interested, and also learn more about what everyone is working on. Thanks!

Welcome to the party. You'll fit right in. Every now and then I get excited about concatenative programming. A certain purity.

Would definitely be interested in seeing some demos of Keykapp šŸ™‚

@Jack Rusher I would love that, thanks! The more readily-available are some old demos focusing more on the "no more buttons than actuators" Huffman text entry thing, though there are some hints of generalizing from chars to actions/concatenative-y things there. ā€¢ Here's one on mobile

ā€¢ Here's one on desktop, typing using only the homerow:

(with the goal of using something like TapXR) There's a more recent prototype based on min-lang focusing on the interactive programming part, so I'll dust that off and record some demos too. Really love the idea of the #two-minute-week btw, should help me ship more šŸ˜…
