METHOD AND SYSTEM FOR GENERATING HISTORY OF BEHAVIOR
First Claim
1. An activity history generating method of generating an activity history with a sensor, which is worn by a person to measure living organism information, and a computer, which obtains the living organism information from the sensor to identify an action state of the person, comprising the steps of:
- obtaining the living organism information by the computer and accumulating the living organism information on the computer;
obtaining, by the computer, an action count from the accumulated living organism information;
extracting, by the computer, a plurality of points of change in time series in the action count;
extracting, by the computer, a period between the points of change as a scene in which the same action state is maintained;
comparing, by the computer, the action count of each extracted scene against conditions set in advance to identify action details of the scene;
estimating, by the computer, details of an activity that is done by the person during the scene based on an appearance order of the action details; and
generating an activity history based on the estimated activity details.

Abstract
Disclosed are method and system for generating history of behavior that is capable of simplifying input of a behavior content of a human behavior pattern determined from data measured by a sensor. A computer obtains biological information measured by a sensor which is mounted to a person and accumulates the biological information, obtains motion frequencies from the accumulated biological information, obtains time-series change points of the motion frequencies, extracts a period between the change points as a scene which is a period of being in the state of an identical motion, compares the motion frequencies with a preset condition for each extracted scene and identifies the action contents in the scene, estimates the behavior content performed by the person in the scene on the basis of the appearance sequence of the action contents, and generates the history of the behaviors on the basis of the estimated behavior contents.

7. An activity history generating system, comprising:
-
a sensor worn by a person to measure living organism information; a network for transferring the living organism information measured by the sensor to a computer; and a computer which obtains the living organism information from the network to identify an action state of the person and, based on the action state, generates a history of activities done by the person, wherein the computer comprises; a data storing unit for accumulating the living organism information; a scene splitting module for obtaining an action count from the living organism information accumulated in the data storing unit, and for obtaining a plurality of points of change in time series in the action count to extract a period between the points of change as a scene in which the same action state is maintained; an activity detail analyzing module for comparing the action count of each extracted scene against conditions set in advance to identify action details of the scene, and for estimating details of an activity done by the person during the scene based on an appearance order of the action details; and an activity history establishing module for generating an activity history based on the estimated activity details. - View Dependent Claims (8, 9, 10, 11, 12)
