When thinking of ubiquitous computing I don’t imagine a world with distracting augmented displays embedded in eyeware. I imagine no display.
Perhaps it’s like in the TV show Person of Interest where one of the characters, Root, communicates with a sentient machine by hearing near-ultrasonic noises. Esoteric and unnecessary high-pitched noises aside, if that is a desired reality how far are we really from seeing that happen?
I’m not talking about a sentient AI that helps people solve crimes, I’m talking about using the computer outside, in a park, and not worrying about the sun glare because you don’t want a screen. With the side-effect that if you ever lose your vision things won’t be so bad.
To explore this reality I will look into how blind people use the computer; specifically the tools and setup of blind programmers. The input device will be the keyboard. The ultimate output device in my mind is confidence that the input was successfully received (no news is good news), a short feedback loop to correct any mistypings or misunderstandings (both on human or computer side) with auditory feedback facilitating input correction interaction.
There are many conventions of the command-line interface which make using a computer a delight but there are also some that people have either grown to accept as local-optimum or they have never contemplated the possibility of anything different. One of those things is filesystem navigation.
Blob storage has the advantage of feeling slightly more modern. You don't need to create folders. You don't have empty folders. Things either exist or they don't.
