110 ambient sensors were installed in a home which, combined with wearable sensors, collected extensive daily routine data. Researchers discovered abnormalities that often go unnoticed by doctors by extracting “opened door” or “walked” events that match an individual’s way of walking from sensing data. They then observed whether the events happened simultaneously or sequentially, identifying behavior changes that might indicate a decline in health.
The sensor system can be used support seniors aging in place. Fujitsu plans to test the technology outside of smart houses in an effort to develop medical applications.
