My neighbor has MS and can't physically move ( his head and he can still talk, but not the rest of his body) Is there anything that i can buy to improve his quality of life with? Even something small could be useful.
Otherwise, one suggestion would be controllers for quadriplegics. There are a few options out there, afaik most are controlled with your mouth but there are also gaze-tracking options. I believe the XBox accessibility controller is compatible with some of them.
