METHOD, DEVICE, AND PROGRAM FOR DETECTING LIVING ABNORMALITY

摘要

PROBLEM TO BE SOLVED: To provide a living abnormality detector capable of objectively detecting living abnormality without placing a burden on a residence. SOLUTION: The living abnormality detector for detecting a living activity out of the ordinary of the residence comprises a sensor information storage means 2; a sensor pattern generation means 4 for acquiring a sensor reaction pattern by cutting out sensor information in a predetermined time window to an optional time; a cluster analysis means 6 for acquiring a cluster corresponding to each time by cluster analysis, based on each sensor reaction pattern; a generality calculation means 8 for extracting a plurality of unit time zones having a predetermined time width from a monitoring time zone and determining a generality of each unit time zone for every measuring day, based on the transition of cluster; a generality analysis means 9 for calculating an average value of generality and a standard deviation in each unit time zone; and a living abnormality determination means 10 for determining a living abnormality by evaluating the generality in a specified unit time zone that is an evaluation object, based on the average value of generality and the standard deviation.
