Abstract: 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.

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.

Abstract: 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.

Abstract: An oral function visualization system includes: an outputter that outputs information for prompting a user to utter a predetermined voice; an obtainer that obtains an uttered voice of the user uttered in accordance with the output; an analyzer that analyzes the uttered voice obtained by the obtainer; and an estimator that estimates a state of oral organs of the user from a result of analysis of the uttered voice by the analyzer. The outputter outputs, based on the state of the oral organs of the user estimated by the estimator, information for the user to achieve a state of the oral organs suitable for utterance of the predetermined voice.
