It’s been 19 years since Pixar released Monsters, Inc. with all that CGI hair. Where are my hairy icons? Ones that get all long and knotted as the notifications number goes up.
Why can’t I feel my phone? I found that paper from 2010 (when I was complaining about keyboards) about using precision electrostatics to make artificial textures on touchscreens.
I should be able to run my thumb over my phone while it’s in my pocket and feel bumps for apps that want my attention. Touching an active element should feel rough. A scrollbar should *slip. Imagine the accessibility gains. But honestly I don’t even care if it’s useful: 1.5 billion smartphone screens are manufactured every year. For that number, I expect bells. I expect whistles.
A Fermi estimate is a quick-and-dirty solution to an arbitrary scientific or engineering analysis problem. Fermi estimation uses widely known numbers, readily observable phenomenology, basic physics equations, and a bunch of approximation techniques to arrive at rough answers that tend to be correct within an order of magnitude or so. The term is named for Enrico Fermi, who was famously good at this sort of thing.
…It struck me that there is counterpart to this kind of thinking on the synthesis side, where you use similar techniques to arrive at a very rough design for a complex engineered artifact. I call such a design approach Dyson design, after the physicist Freeman Dyson, who was one of the best practitioners of it (not to be confused with inventor James Dyson, whose designs, ironically, are not Dyson designs).
