State detection method, state detection device, and recording medium

A state detection device comprising:

• a processor configured to:
• record first information obtained from a first sensor and second information obtained from a second sensor in a predetermined, segment in a storage;
• specify a behavior segment indicating a segment in which a subject performs a specific behavior and a non-behavior segment indicating a segment in which the subject does not perform the specific behavior using the second information recorded at the recording;
• determine a feature amount to be used for detecting a specific state of the subject using respective values of a plurality of feature amounts included in the first information stored in the storage in each of the behavior segment and the non-behavior segment and determine a threshold value for the determined feature amount, for distinguishing a behavior and a non-behavior;
• and
• detect the specific state of the subject from the information obtained from the first sensor using the feature amount and the threshold value determined at the determining.

A non-transitory computer-readable recording medium storing a state detection program that causes a computer to execute a process comprising:

• storing first information obtained from a first sensor and second information obtained from a second sensor in a predetermined segment in a storage;
• specifying a behavior segment indicating a segment in which a subject performs a specific behavior and a non-behavior segment indicating a segment in which the subject does not perform, the specific behavior using the second information stored in the storage;
• determining a feature amount to be used for detecting a specific state of the subject using respective values of a plurality of feature amounts included in the first information stored in the storage in each of the behavior segment and the non-behavior segment and determining a threshold value for the determined feature amount, for distinguishing a behavior and a non-behavior;
• and
• detecting the specific state of the subject from the information obtained from the first sensor using the determined feature amount and the determined threshold value.
