Outside of the dev needs take a look at bemyeyes.com, it allows a person with vision problems to video call a volunteer to help answer questions. I've helped people read labels, sort boxes of chocolate for Christmas presents and help a person find the login dialog after they lost track ofwhere it was. Each call only took a minute or two. Highly recommended to volunteer, only takes a minute to help and you don't have to answer the call if you are unavailable, it just hops to another volunteer.
