I needed a project that I can use, so that I see how far I can go with only AI usage. I needed something doable, but relatively complex. And then I remembered an idea my wife shared with me, a few years ago: an app that monitors her grandfather's behavior and sends a notification if he stops moving. at that time, AI integrations were not considered as an option, and static algorithms to model behavior (with adaptation) were complex and fragile.
