UWB has three major high-value application scenarios in home-based elderly care.

Safety Alert: Falls and Disappearances,Health Monitoring: Daily Activity Analysis,Care Assistance: Enhancing Efficiency and Dignity.

1.Safety Alert: Falls and Disappearances
This is a fundamental need in the elderly care scenario and also the area where UWB demonstrates its greatest value.
Fall detection: By combining UWB radar with AI algorithms, it can identify abnormal postures such as falls and徘徊 (stumbling), and automatically trigger an alarm.
Electronic fence: Virtual boundaries are set up in dangerous areas such as the kitchen and stairwell. Once the elderly approach, the system will give an early warning and automatically lock the door.
Anti-Detour: For elderly people with cognitive impairments, the system can define a safe zone. Once they leave it, an alarm will be triggered. The positioning accuracy can reach centimeter level, which is much higher than that of Bluetooth.
2. Health Monitoring: Daily Activity Analysis
UWB can "unobtrusively" analyze the daily routines of the elderly, offering greater privacy protection compared to cameras.
Activity Recognition: By analyzing the trajectories, daily activities such as eating, grooming, and walking can be automatically identified, with an accuracy rate as high as 94%.
Health monitoring: The UWB radar can even detect vital signs such as breathing and heartbeat, enabling non-contact monitoring.
Behavior analysis: It can intelligently identify abnormal behaviors such as nocturnal wandering and excessive gathering, with an accuracy rate exceeding 90%, and assist in judging the trend of physical decline.
3. Care Assistance: Enhancing Efficiency and Dignity
For semi-disabled elderly individuals, UWB can help them regain some degree of autonomy.
Indoor navigation: Elderly people wear simple devices and the system provides voice guidance to lead them to the restaurant and activity room.
Efficient Response: When the elderly press the SOS button, the system will immediately locate the specific room and position, facilitating the caregivers to arrive promptly.
