We have been developing an RFID (radio frequency identification) mat system to assist caregivers in a group home. In Japan, the number of group homes offering home-like care for elderly persons suffering from dementia has increased considerably. Even though the smaller number of people residing in a group home makes it suitable for family-like care, the scarcity of caregivers increases the burden, especially during the night. To augment caregiver attention, we developed floor mats with embedded RFID antennae and slippers with RFID tags. These can help caregivers be aware of the activities of persons suffering from dementia by specifying whether an individual has passed over a mat in a particular corridor. This not only helps the caregivers understand such persons by reviewing their activities but also keeps them informed about their current activities. We introduced the floor mats in a real group home and confirmed the feasibility of the system. In this study, we describe the system and lessons learned from our experiment.
