Hat with electro-oculogram detection electrode, headwear with electro-oculogram detection electrode, and alert method using electro-oculogram detection

摘要

PROBLEM TO BE SOLVED: To contribute to prevention of occurrence of accidents due to mental and physical conditions of a driver (user) of a bus or a train.SOLUTION: A conductor cap according to one embodiment has a band portion in contact with the forehead of a user, and a chin strap. The band portion and the chin strap include a first electrode pair (151a, 151b) and a second electrode pair (152a, 152b). In the first electrode pair, the second electrode (151b) is configured to be movable on a chin strap (210R) so that an area of a right eye center (P2) comes on a line connecting the first electrode (151a) and the second electrode (151b). In the second electrode pair, the fourth electrode (152b) is configured to be movable on a chin strap (210L) so that an area of a left eye center (P1) comes on a line connecting the third electrode (152a) and the fourth electrode (152b). An eye movement detection unit (15) detects a right eye potential by the first electrode pair (151a, 151b) and detects a left eye potential by the second electrode pair (152a, 152b). Physical and mental conditions (such as drowsiness and mental stresses) of the user are estimated from detection results (pattern of eye potential changes) of the eye movement detection unit (15) to help prevention of accidents and the like.SELECTED DRAWING: Figure 4
