Abstract: The present invention provides an eating monitoring method for judging whether chewing is performed or not by a chewing judgment algorithm on the basis of a temporal variation in a measured value of a sensor unit configured to detect a movement of a jaw while a person takes a meal, the person wearing a detection device comprising the sensor unit. The method includes the steps of: adjusting the chewing judgment algorithm on the basis of a variation in a measured value of the sensor unit, the variation corresponding to a chewing action or a mouth opening/closing action of the person wearing the detection device; and judging whether chewing is performed or not by the chewing judgment algorithm which has been adjusted, and measuring the number of chews on the basis of a temporal variation in a measured value of the sensor unit during the meal.

Abstract: A body-attachable detection device includes a light-emitting unit; a photoelectric conversion unit; a control unit; and an attachment portion, wherein the attachment portion is provided to attach the light-emitting unit, the photoelectric conversion unit, and the control unit to a living body, the light-emitting unit is configured to project light onto a target part from which movements of the living body are to be detected, the photoelectric conversion unit is configured to receive light reflected by the target part and to generate photocurrent, and the control unit is configured to adjust, in accordance with the photocurrent generated in the photoelectric conversion unit, an amount of light to be projected onto the target part and to detect movements of the target part in accordance with changes in photocurrent that occur in the photoelectric conversion unit after the amount of light is adjusted.
