Definitely going to look into this. I'm a blind screen reader user and, when I had a phone with physical buttons, I could have it in my pocket connected to an external braille device or pair of headphones. I could easily carry on conversations, browse the web, ask for help, all sorts of things without taking it out of my pocket, and nobody had to know I was doing anything.
With a touchscreen phone I can't really do any of that. Even if I can listen to notifications in an earphone with the phone in my pocket, I can't take care of them unless I take the phone out. Plus, wearing earphones and walking around in public when you can't see isn't wise.
