Abstract: A cognitive function evaluation device includes: an obtainment unit that obtains use information indicating a state of use of a toilet by a subject; a calculation unit that calculates a total number of times of use of a toilet by the subject, based on the use information obtained by the obtainment unit; an evaluation unit that evaluates a cognitive function of the subject, based on the total number of times of use calculated by the calculation unit; and an output unit that outputs a result of evaluation performed by the evaluation unit.

Abstract: A cognitive function evaluation device includes: an obtainment unit that obtains utterance data indicating a voice of an evaluatee uttering a sentence as instructed; a calculation unit that calculates, from the utterance data obtained by the obtainment unit, a feature based on the utterance data; an evaluation unit that compares the feature calculated by the calculation unit to reference data indicating a relationship between voice data indicating a voice of a person and a cognitive function of the person to evaluate the cognitive function of the evaluatee; and an output unit that outputs the sentence to be uttered by the evaluatee and outputs a result of evaluation by the evaluation unit.

Abstract: A cognitive function evaluation device includes: an instruction unit that instructs quick pronunciation of pseudoword in which a predetermined syllable is repeated; an obtainment unit that obtains voice data indicating a voice of an evaluatee who has received an instruction; a calculation unit that calculates a feature from the voice data obtained by the obtainment unit; an evaluation unit that evaluates a cognitive function of the evaluatee from the feature calculated by the calculation unit; and an output unit that outputs a result of the evaluation by the evaluation unit.

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.
