Abstract: A sleep onset determination method includes: detecting a light-out time that is a time at which illuminance in a room becomes less than or equal to a predetermined value; storing the light-out time detected in the detecting of the light-out time and a time period including the light-out time detected; and determining whether a user fell asleep at a currently detected light-out time, based on the light-out time and the time period stored in the storing of the light-out time.

Abstract: A dementia determination system (100) includes: an acquisition unit (111) configured to acquire a long press ratio which is a ratio of a number of long presses in which a button of an operating device (140) is pressed for a time longer than a reference time, to a number of presses of the button of the operating device (140) used by a user to operate an electric device (130); a determination unit (112) configured to determine a dementia level of the user based on the long press ratio acquired by the acquisition unit (111); and an output unit (113) configured to output dementia information indicating the dementia level determined by the determination unit (112), wherein the determination unit (112) is configured to determine that the dementia level is more severe as the long press ratio is lower.
