Abstract: A sleepiness estimating device including an auxiliary information acquirer that acquires auxiliary information including at least one of five-sense information perceived by a person or emotion information indicating an emotion of the person; and a sleepiness estimator that estimates a sleepiness of the person based on the auxiliary information.

Abstract: An inattentive state determination device includes: a drowsiness predictor that derives drowsiness prediction data for predicting an occurrence of drowsiness in a person; a drowsiness and inattentiveness deriver that derives a degree of drowsiness and inattentiveness of the person; and an inattentiveness determiner that determines whether the person is in an inattentive state, based on the drowsiness prediction data and a current degree of drowsiness and inattentiveness.

Abstract: A state detection device (100) detects a state of a driver driving an automobile (300), and includes: a first camera (110) that captures a face of the driver at a first frame rate; a. second camera. (120) that captures an environment in a forward direction of the automobile at a second frame rate; and a. processor (130) that processes images obtained from the first and second cameras (110, 120). The processor (130) calculates a :line-of-sight direction of both. eyes of the driver based on a face image obtained from. the first camera (110) and calculates a focal position of the driver based on the hue-of-sight direction. of both. eyes of the driver, and detects the state of the driver by determining the state of the driver based on the focal position and a forward image obtained from the second camera (120).

Abstract: A sleepiness estimating device including an auxiliary information acquirer that acquires auxiliary information including at least one of five-sense information perceived by a person or emotion information indicating an emotion of the person; and a sleepiness estimator that estimates a sleepiness of the person based on the auxiliary information.

Abstract: A sleepiness estimating device includes a biometric information acquirer that acquires biometric information of a person, an auxiliary information acquirer that acquires auxiliary information including at least one of five-sense information perceived by the person or emotion information indicating an emotion of the person, and a sleepiness estimator that estimates a sleepiness of the person based on the biometric information and the auxiliary information.
