In-home 3D sensor system to spot falls without wearables

Using Structured Light Sensing with Machine Learning to Detect Unwitnessed In-Home Falls

NIH-funded research Applied Universal Dynamics Corporation · NIH-11177677

This project builds a small, unobtrusive 3D sensor and smart software to automatically detect when older adults fall at home and trigger alerts when they cannot use a wearable button.

What this research studies

From my perspective as someone living at home, this system uses a structured light 3D sensor that makes a point-cloud picture of a room and machine learning that learns the motion patterns of falls. The device sits quietly in the home and does not require me to wear anything or push a button. When the software detects a likely fall, it can send an alert so help can arrive sooner. The project builds on earlier (phase I) tests and focuses on making the system reliable, low-cost, and easy to install in real homes.

Who could benefit from this research

Good fit: Ideal candidates are adults aged 65 or older, especially those living alone or with mild to moderate memory problems who may forget to wear or press emergency pendants.

Not a fit: People who live in nursing homes or assisted-living facilities with existing monitored systems, or those who do not want in-home sensors for privacy reasons, may not benefit from this system.

Why it matters

Potential benefit: If successful, the system could get help to fallen older adults faster, reducing complications from long periods on the floor and possibly lowering injury-related costs.

How similar studies have performed: Related camera- and depth-sensor fall-detection projects have shown promising results in lab and limited home pilots, but large-scale, real-world in-home testing is still fairly limited.
