Howard's wife has severe neuropathy and needs a way to use her iPhone without touching the screen. Leo says that the iPhone has some of the best Accessibility features, so using SIRI and voice activation could be the best bet. But Bixby in the latest Android phones is better at voice control. Go into the iPhone's settings under Accessibility and see what's available. She can call Apple and see what they can do because they have great Accessibility support. In iOS12, there are also SIRI Shortcuts, which enables users to use verbal cues to run shortcuts.
How about accessibility for the TV? Leo says that the Amazon Fire TV Stick or Cube works great for that.
