One of the reasons I've stopped listening to music as I walk is that you can't press a touchscreen through mittens. I often listen to 2 minutes of a song, or skip it entirely, and I can't do that without removing my mittens every time, taking my device out of my pocket, and physically looking for the next button. These things don't like the cold, and it's cold here 7 months of the year.
I can't use a device without opening my eyes anymore, no matter how bad my migraines are.
Because there isn't a pressure requirement, my sensory issues don't cause me to break as many buttons on a touchscreen, but I also can't tap anything gently while thinking, which is awful for my ADHD.
I often find myself in completely different parts of an app, or a different app entirely, because my hyperactive fingers keep playing with the screen.
I don't have good manual dexterity, so half the time my press registers as a swipe, or long press, or some other movement, and apps do unexpected and stressful things.
I CAN NO LONGER READ MENUS!!!
The smart boards that constantly cycle through options? I can't read them. They change half-way through an option, and it erases everything I've read. I can't compare things. Decision making is hard enough, now I have a time limit and visual noise?!
(That last one isn't a touchscreen issue, but the loss of physical menus feels related.)
