This is something that AARP should be on. Yes, I know that most seniors, even very old ones (over 80) have smartphones, but an awful lot do not, and many who do have a rather uneasy relationship with it. Every update comes with user interface changes that have to be learned, and I see my older relatives who do have smartphones having various levels of trouble learning them each time. Eventually, they give up on functions that change too much (Apple, I’m talking about Camera and Photos on the iPhone)
Despite personally liking my iPhone, I’m looking to help protect the rights of my relatives to live their lives and access public services without smartphones or personal internet access.
There are seniors; there are also those who simply will not carry a
device that constantly broadcasts their position and contains
microphones and cameras that are ultimately controlled by some
company.
And visual detection more precise. You can tell not only if someone is usually within a few tens of metres as you can with cellphone data, but exactly where they are, what they're doing, and who/what they're looking at.
