Tech toys may help prevent resident falls

The same technology used in video games and security systems is being used to detect illness or falls among long-term care residents, according to researchers. Scientists at the University of Missouri are developing a device — usually used in creating video games — that employs infrared light to produce a silhouette of the person being monitored, rather than a video or photograph. They are also designing a second device that uses Doppler-radar technology to recognize whether a resident is walking, bending and executing other movements. These changes of position could indicate whether a resident has fallen.
