A quiet house that notices: sensors in Atlanta homes learn the early signs of loneliness

Loneliness rarely shows up in a doctor's office — older people seldom mention it, and a short appointment cannot see it. So researchers from Virginia Commonwealth University and Emory University installed HomePal, a gentle system of motion, door, sleep and TV sensors plus smart speakers, in the homes of 70 adults aged 65 and over in metro Atlanta for three months. The system watches everyday patterns — moving less, sleeping differently, fewer calls — and compares them with how lonely people say they feel, training an AI to flag the early drift toward withdrawal while there is still time for a visit, a call, a human response. 'We are not diagnosing loneliness,' says lead author Mohamed Kamel. 'We are looking for patterns that may deserve a follow-up.' The study is published in the journal Assessment.
