摘要： A dementia symptom detection system includes an information processor which determines the level of dementia of a user based on (i) a reference value which is for an index corresponding to behavioral and psychological symptoms of dementia and which is determined based on the history of the activity amount stored in storage and the history of device operation information stored in the storage, and (ii) a personal value of the user which is for the index and which is determined based on the detected activity amount of the user and the obtained device operation information of the user.

摘要： A motion display system includes: a detector that detects an acceleration of a body part of a test subject; an imager that generates a moving image by imaging a motion of the test subject; an identifier that is attached to the test subject to determine a position of the body part within the moving image; a superimposer that superimposes a motion trajectory of the body part generated based on the acceleration detected by the detector on a position of the body part determined based on the identifier within the moving image generated by the imager in synchronization with the moving image; and a display that displays the moving image on which the motion trajectory is superimposed by the superimposer.

摘要： Cognitive function evaluation device includes: storing unit storing reference data on the relationship between the periodicity of a body movement of a person walking and the cognitive function level of the person; acquiring unit that acquires body movement data on the detected body movement from body movement sensor that detects the body movement of subject walking; and calculating unit that calculates the periodicity of the body movement while walking from the acquired body movement data and checks the calculated periodicity against reference data stored in storing unit so as to identify the cognitive function level corresponding to the calculated periodicity.

摘要： Cognitive decline detection system includes obtainment unit and determination unit. Obtainment unit obtains the amount of movement during a sleep period and the amount of movement during a non-sleep period of a user for each day, the non-sleep period being the period other than the sleep period. Determination unit determines that the cognitive function of the user is lower during a determination period than during a comparison period set before the determination period when the frequency of days when a movement amount ratio falls below a predetermined ratio among days constituting the determination period is higher than that among days constituting the comparison period, the movement amount ratio representing the ratio of the amount of movement during the non-sleep period to the amount of movement during the sleep period.

摘要： A dementia determination device in a dementia information output system includes an obtainer which obtains, on a per unit period basis, the result of measuring body motion of a user in a sleep time period; and an outputter which outputs dementia information indicating the likelihood that the user is developing a mild cognitive disorder based on the occurrence frequency of a unit period in which the magnitude of a difference between reference data on body motion of a healthy subject in a sleep time period and the result of measuring obtained by the obtainer exceeds a predetermined threshold value.

摘要： 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.
