iPad solution for a Blind Student with CP

Before I even get into this, I honestly have no idea what I'm asking. My TVI has a first grade student who is totally blind and only has use of one hand due to CP. She's looking for a way to use an iPad, but has had no success with braille displays because she can't move individual fingers, so she really needs something that's just a joy stick or arrow keys that will connect to an iPad. She mostly just needs a way to listen to class material right now because she can't read braille. I suggested Voice Dream Reader, but she needs a physical device that will allow her to navigate the iPad without pressing extra buttons. Like I said, we really don't know what we're looking for or what's even out there, so I thought I'd put it out to the community. Any and all suggestions are welcome! Thanks in advance!
