Embodiment approach 1

[0035] In this embodiment, a method of estimating the state of a subject person and a state estimation system will be described. Note that abnormality of the target person can be detected by using the method of estimating the state of the target person described in this embodiment, and thus this method of estimating the state of the target person can also be called a method of detecting abnormality of the target person. In addition, by using the state estimation system described in this embodiment, it is possible to detect an abnormality of the subject person, and thus this state estimation system can also be called an abnormality detection system.

[0036]

[0037] First, a method of estimating the state of a subject person will be described.

[0038] Fatigue is felt when an autonomic or hormonal imbalance affects the brain or body. Stress can be cited as one of the causes of autonomic or hormonal imbalance. That is, stress causes autonomic or hormonal imbalances that cau...

Abstract

Provided is a method for estimating the state of a subject person in consideration of individual differences. The method includes: a step of estimating a state of a subject person from second data including a change speed of a pupil area of the subject person by using a statistical model of a first data estimation parameter, the first data including a plurality of data groups having data of states of the plurality of persons and a change speed of a pupil area of the subject person; and a step for outputting the estimation result of the state of the subject person. Note that the statistical model is a hierarchical Bayesian model using ordered logistic regression, where the linear predictor is the sum of intercept, the product of partial regression coefficients and explanatory variables, and parameters representing individual differences.

Description

technical field [0001] One aspect of the present invention relates to a method of generating a statistical model. Also, one aspect of the present invention relates to a method of estimating the state of a subject person. Another aspect of the present invention relates to a state estimation system. Background technique [0002] Properly managing health status is an important issue. The accumulation of fatigue causes a deterioration of the state of health. Fatigue can be divided into physical fatigue, mental fatigue and nervous fatigue. Symptoms that occur due to the accumulation of physical fatigue are easier to self-knowledge. On the other hand, symptoms that occur due to the accumulation of mental fatigue or nervous fatigue are often not easy to recognize. If mental fatigue or nervous fatigue can be quantified, the state of the subject can be judged objectively. That is, if the fatigue degree, stress state, etc. of the subject person can be estimated, the health state...
