Need Gift Advice

I really need some suggestions for Christmas gifts for elderly parents (in-laws). None of the things we used to buy for them seem appropriate anymore, given their lifestyle and physicial limitations. Father-in-law will probably soon be in a wheelchair, due to neurological problems; mother-in-law has diabetes and decreased mobility as well. They're (for now) still living in their home, but don't really want to buy household items that they would just have to pack up when they move to more accessible housing (which they have decided to do.) Their eyesight is not very good, so reading materials are not appropriate; candy is out, due to the diabetes. Just really running out of ideas this year, and was hoping someone could help me out. Thank you very much for any and all suggestions!!
