The monitoring system of irregular state using pattern of person's moving locus

摘要

We propose a monitoring system for a high aged person. Using our this system, we intend to check non-daily moving patterns of the object person, and reports (if necessary) an irregular state of moving pattern to the monitoring facilities. In general, the number of moving patterns would be limited in the case of a high aged person living in a room. It is possible to learn the frequently appeared moving patterns by a system like a HMM system. Moving patterns of the person is applied to the HMM system, the system does not accept the input patterns in the case when non-daily moving patterns appeared. Such a case could be supposed an irregular state of the living life of the object person. Soon after, the system reports an alarm of happening of the irregular state according to demand.
