My mom is confined to a bed, and also suffers from mild dementia. I download apps that are appropriate for her and she can play/use them because she doesn’t have to use a mouse, just her finger (although she was very computer saavy before her illness...a mouse would be too complicated at this point.)
I also use my iPad as a babysitter, LOL. My grandnieces love a virtual paperdoll app, it’s very creative.
My son is grown, but I homeschooled, and when I see the apps available I think that the iPad would be a great addition to any homeschooler. We used electronic passive learning (like the geosafari) and there are many apps on the iPad that create the same learning situation.
Your remark about the non-mouse actions is interesting. My Dad also had tremors in his hands; his use of a mouse was labored. But the IPad helped him enjoy his games.
Good luck and God’s blessings for your work with your Mom.
