Sensor Equipped Environments Could Help Care for Dependent People

The system offers many possibilities, such as the option to automatically open doors when the receiver gets closer to them, or braking a wheelchair when the patient sitting in it approaches dangerous areas such as staircases. The new system could also be very useful for remote care social services, since all the information on the movements and activity of the patients in the homes the system receives could be monitored and controlled from a central location.

"The prototype has produced excellent results regarding the effectiveness to recognize the moving object, and we are now working to optimize the design of the different devices and improve the variables it can control," said project leader Prof. José Carlos Segura Luna, Ph.D., of the department of signal theory, computer networks, and communications at UGR. "The equipment developed is more accurate, cheaper and is much less affected by the noise compared to the reference location system."

The system is expected to be expanded by increasing the range and type of spaces where it can operate by complementing other communication methods, such as ZigBee language (a technology similar to Bluetooth) or global positioning system (GPS), which will allow installing the technology in larger buildings with many rooms, and eventually in open spaces. Thus, by combining several different location techniques, the system will eventually integrate all available information into a cohesive whole.
