What are some devices/technology that would be useful to a person with limited use of his hands. I'm specifically interested in classroom adaptive assistance for a high school or college-age character - ebooks rather than textbooks, recorder for note taking, etc. If he has trouble writing and with fine motor skills, what would be useful for science labs and showing work in math classes among other things? It's not a huge factor for my story, but I want to get the details right. Classroom tech is where I'm focusing right now, but any helpful ideas for this guy would be awesome.
