Telemonitoring system using the TV operating-state to follow activity of elderly individuals
Caregivers and medical staff members would like to monitor the activity of elderly individuals under their care throughout the individuals daily lives.We assume that the activity of elderly individuals inversely correlates with periods during which they watch television.We developed a telemonitoring system based on the television operating-state (TVOS) to follow the activity of elderly individuals.The system is comprised of sensor circuits,a PC with an Internet connection,and a server computer.The PC acquires the TVOS via a USB port from both a current sensor attached to the TVs power line to determine whether the TV is on or off and from an infrared sensor to determine whether a remote controller is in use or not.The PC transfers the TVOS to the server via the Internet once every minute.In this preliminary study,an 80-year-old female used the system for three months.She had left hemiplegia but was self-supporting regarding the activities supporting her daily life.A pedometer was attached at her waist,and her total numbers of steps per day were recorded by medical staff members.The regular rhythms of the TVOS were obtained,and a different TVOS pattern was obtained during a holiday week.Both the period of using the TV and the total numbers of steps per day during the holiday week were compared with those of a non-holiday week,and the statistical differences were obtained by t-test.
