Elderly residents follow predictable behavioral rhythms: consistent wake times, meal routines, afternoon rest periods, and evening activity patterns. Deviations from these rhythms frequently precede clinical health decline by days or weeks—before symptoms become visible. Adaptive IoT for Smart Longevity builds a personalized behavioral baseline and monitors continuously for meaningful deviations, enabling proactive intervention rather than reactive emergency response.
During the first 30 days, the system collects multi-modal data: 60GHz radar sensors map presence duration in each room, a Smart Scale captures daily weight and body composition, a smart mattress sensor measures sleep duration and restlessness, door sensors log departure and return times, and the automated pill dispenser records medication adherence timing. An unsupervised clustering algorithm builds Daily, Weekly, and Seasonal Behavioral Profiles that incorporate normal variability—distinguishing a genuine anomaly from a typical day when the resident slept in after a late family dinner.
From day 31 onward, real-time Anomaly Detection compares current behavior against the established baseline. Key monitored indicators include: Sleep Efficiency declining more than 20% for three consecutive nights (correlates with pain or anxiety), wake time shifting earlier by over one hour for five consecutive days (Early Morning Awakening—associated with depression), body weight dropping more than 2 kg in a single week (nutritional decline signal), and failure to leave the bedroom after 10:00 AM for three consecutive days (possible illness or fall that radar has not separately detected).
The alert system operates in three tiers. Green status: normal variation, no notification sent. Amber alert: a concerning deviation triggers a LINE OA message to the designated family group—worded conversationally in Thai: “Mom has slept less than usual for 3 nights—worth checking in.” Red alert: a high-severity signal such as no movement detected in the home throughout the morning triggers simultaneous LINE OA notifications to all family members with a recommendation to call or visit immediately.
Within Thai family culture, this system serves adult children working in Bangkok while parents remain in the family home in a different province. LINE OA requires no new application adoption. A Daily Summary Report delivered each morning with a traffic-light status (green, amber, red) lets family members assess the situation in 30 seconds—reducing both anxiety and unnecessary travel, while ensuring that genuine health changes are never missed.
