alt Hacker NewsI totally agree, even not going as far as a Parkinson case, if you already so old and not too old persons use phones and touch screens, you will see that very often it is complicated for them to click on the small button at the right place and to have the feeling that "they have clicked".
So, for me, on the argument of about accessibility, the Nothing Phone behavior will work a lot better I think. In their mind they don't count and click 6 times to put the image in a specific position. In addition with considering that it would not make much sense to click 8 times in advance to turn back in the exact position where you are.
The mindset in their case is more: click and wait, compare if it is the position you want and do it again. The other sensitive button that will bufer would probably trigger overshooting, going too far, then too back, etc... similarly to when you have issue scrolling in a list to the right spot.
The case of the iphone would be better only for someone like a younger person, tech nerd, that want things to go fast without having to wait. Same thing for computer keyboards where I could type multiple letters in advance before the first one even show up on the screen with the lag.
Around 2011, my grandfather with Parkinson’s and deteriorating eyesight received an iPad from family. They didn’t use it for much, mostly video calls and reading the Bible, with the text steadily getting larger and larger (up to letters being more than 5cm tall towards the end). It was funny just how good it was if an app only supported iPhone and not iPad, because then the iPad would scale it up to double physical size.
