New Video Gaming Technology to Detect Illness
Many older adults lose their independence as their health declines and they are compelled to move into assisted care facilities. Researchers at the University of Missouri (MU) and TigerPlace, an independent living community, have been using motion-sensing technology to monitor changes in residents' health for several years.
Now, researchers have found that two devices commonly used for video gaming and security systems are effective in detecting the early onset of illness and fall risk in seniors.
Marjorie Skubic of MU College of Engineering is working with Erik Stone to use the Microsoft Kinect, a new motion-sensing camera generally used as a video gaming device, to monitor behavior and routine changes in patients at TigerPlace. These changes can indicate increased risk for falls or early symptoms of illnesses.
"The Kinect uses infrared light to create a depth image that produces data in the form of a silhouette, instead of a video or photograph," said Stone. "This alleviates many seniors' concerns about privacy when traditional web camera-based monitoring systems are used."
Another researchers of MU develop a fall detection system that uses Doppler radar to recognize changes in walking, bending and other movements that may indicate a heightened risk for falls. Different human body parts create unique images, or "signatures," on Doppler radar. Since falls combine a series of body part motions, the radar system can recognise a fall based on its distinct "signature."
"Falls are especially dangerous for older adults and if they don't get help immediately, the chances of serious injury or death are increased," said Stone. "If emergency personnel are informed about a fall right away, it can significantly improve the outcome for the injured patient."
Both motion-sensing systems provide automated data that alert care providers when patients need assistance or a medical intervention. The systems currently are used for monitoring residents at TigerPlace in Columbia. Skubic says the system allows residents to maintain their independence and take comfort in knowing that illnesses or falls may be detected early.
