Watch-Out: Real-Time Tracking and Assistance for Wandering Alzheimer's Patients Using Wearable Technology

Wandering poses a critical safety risk for individuals with Alzheimer's disease, leading to injuries, fatalities, and immense caregiver stress. This paper introduces Watch-Out, a comprehensive safety system combining a smartwatch app, an NFC-enabled smart door lock, and a caregiver mobile app to address wandering behaviors. The system employs NFC tagging and voice prompts to ensure cognitive engagement during exits, reducing the likelihood of unsupervised wandering. Features include real-time GPS tracking, geofencing alerts, health monitoring, and community-based emergency response mechanisms. Grounded in user-centered design and insights from caregivers and experts, Watch-Out enhances patient autonomy while alleviating caregiver burdens. By integrating technology with empathy, the system ensures safety and dignity for patients while fostering peace of mind for caregivers. This solution redefines Alzheimer's care, paving the way for safer, more supportive communities.
