Turing completeness for all
June 25, 2019 · Last updated: September 19, 2019
Hi, I’m Helder, aka @agentofuser.
I’m a computer engineer and entrepreneur working to bring the gift of computing to all through User Agency Design.
My current research is on maximizing the human upload bandwidth with #Keykapp🧢—an inclusive, predictive, and programmable keyboard for all.
I also have particular opinions about end-user programmability
teachable interfaces,
which I want to validate and explore with Keykapp.
I believe everyone should have the power to adapt, improve, and automate their tools, and I have a feeling that #keyboardFirst design is a big part of making this power accessible to people who don’t write software professionally and people with disabilities.
Giving what I can
I donate at least 10% of my gross monthly income to charities and public-interest work. Among other things:
- I fund direct and unconditional cash transfers to people in need via GiveDirectly.
- I support the Open Privacy Research Society’s work on the Cwtch metadata-resistant, privacy-preserving messaging app.
- I support the Talon project for inclusive hands-free input.
- I donate to content creators and public-interest initiatives via Brave Tips.
Areas of interest
- Accessibility
- Privacy / Consent
- The (D)Web Platform
- Async/Offline Interaction Design
- Bayesian Epistemology
