Researchers at the University of Granada in southern Spain have developed a system that uses RFID tags to identify users’ daily behavior, helping to remind older people with special needs of routine tasks, such as carrying keys or taking medicine.
The stickers are attached to the objects the user touches most often and communicate with a computer or mobile device in the room or in a nearby assistance center.
User behavior is assessed through artificial intelligence technology and compiled into a series of behaviors, such as remembering to take keys or mobile phones before leaving the room.
The system can monitor users’ behavior by assessing when they touch an item, then sound a small alarm and display prompts on the mobile device to prompt the user to act accordingly.
María Ros Izquierdo, a researcher at the university and one of the developers of the system, said: “The system facilitates the behavioral control of people with special needs and increases their independence without interfering with the user’s life.”
“The system doesn’t require cameras or loudspeakers, the device is easy to operate, and the user doesn’t need to change their routine,” he said.
The researchers designed a mock room specifically to evaluate the system, using embedded sensors to identify occupant behavior.
The researchers monitored users and built a personal database and asked participants to confirm the stability of the system and the degree to which they felt disturbed.
Izquierdo thinks the system is very useful for older people who are independent and often refuse help from others.
