I'm sensing an uncomfortable amount of human labor behind this. Even worse it appears to be labor done for the sake of the thing itself. shudder Terrible and makes me feel bad about myself. Back to the AI slop I go!
When your finger gets close to the [touch] screen it causes a disturbance in the *magnetic* field that the electrodes sense.
When your finger gets close to the [touch] screen it causes a disturbance in the *magnetic* field that the electrodes sense. Surely they mean electric field - for a capacitive touch screen.
This reminds me aesthetically of The Way Things Work [1] which was one of my favorite books as a kid. Having a similar wordly reference as an adult has been a goal for a while. [1] https://www.indigo.ca/en-ca/the-way-things-work-newly-revise...
A cool recent one for large-scale infrastructure is "Engineering in Plain Sight": https://practical.engineering/book
Too much name dropping of random pieces without offering any insights why they are needed. You learn much more just skimming through a wiki article.
If anyone has done this and made success, I'd really like to know how you did it and if there's any tricks to accomplishing that.
The author should make a meta-entry about how he makes the (insanely beautiful) diagrams in the book (ideally walking through the process).

How do you cause a disturbance in an electric field without causing a disturbance in the magnetic field?
A material can affect an electric field without affecting a magnetic field: electrically conductive (versus insulator that won't affect a field so much except via dielectric effects).
A material can affect a magnetic field without much affecting an electric field e.g. ferrites are non-conducting.
A finger changes the capacitance between two "plates" and that is what is detected.
Also the attached drawing shows diamonds but I've only ever seen flat wires myself (when looking closely at touch screens you can sometimes see the transparent sense wires). But I'm no specialist and I don't know how correct the drawing is.

Disagree on the animations. They are both beautiful and detailed, clearly illustrating the point. Your other criticism I agree with.
I agree that they are beautiful and detailed, clearly illustrating the point. I really, really love them. I'd love to have them on my wall. That's not my problem. My problem is that they never stop animating. For me and many other people, when something is moving in our visual field, it is very, very difficult to read the text next to it. Full disclosure: I'm autistic. I was wondering whether I should mention that. A…

In the FAQ: 07 How do you make the illustrations? By hand, in Figma. There's no secret - it's as complicated as it looks.
god damn, that's some patient making animation right there

To imply capacitive touch sensing uses magnetics is just so wrong - I can't imagine how someone trying to be technical could make such an egregious error. A material can affect an electric field without affecting a magnetic field: electrically conductive (versus insulator that won't affect a field so much except via dielectric effects). A material can affect a magnetic field without much affecting an electric field e…
Electric and magnetic fields aren't Independent. Again, I asked about disturbances, Maxwells equations make it pretty obvious that changes in one cause changes in the other.
