Now the elderly can be tracked in their homes using a new technology developed by researchers at Adelaide University. The device is similar to that used for tracking bears.
The Radio-frequency identification can be used to check whether older people are maintaining their normal routine or if they need any assistance. The RFID technology is popularly used in preventing shop lifting; vehicle identification at toll points and in tagging and monitoring bears in the wild.
Lead researcher Michael Sheng said that the technology has not been used on humans but added that it will provide an enormous help for the aging population. "This is becoming a significant problem for most developed countries where the proportion of older people is rapidly increasing and the labor market is tightening -- there are more elderly people to be looked after but less people to do it. We are trying to solve this by developing a system using a network of sensors attached to objects that the person is interacting with in the home; using software to interpret the collected data to tell us what someone is doing", he said.
