Imagine someone blind who also has Parkinson’s - they can’t see to use Voice Access, and they can’t control their hands well enough to interact with the screen physically in a reliable manner using TalkBack. You can’t actually use those two accessibility features together - they are mutually exclusive in that they require you either be able to see the screen, OR you must be able to interact with it physically as it reads out what you’re touching. Why is there no way to interact entirely verbally?
ETA: please see my added example in OP.
iOS will open your Lemmy client, start reading posts to you aloud, and go into a post of interest upon command without you ever looking at or touching the screen (using my newer example that I added to the OP)? I’m seriously going to have to look into getting an iDevice of some sort if so.
