@paco you’re making excellent points. Interestingly enough, using a phone with a screen reader - while not the same tactile experience we’re all looking for - checks some of your boxes:

When you touch a control, the phone announces it. You then double tap to activate it.
To navigate between controls, you can also swipe on the screen (think touchpad) and focus moves to the next one, and the phone announces that.

Using an on-screen keyboard with a screen reader is a whole other story though.
