  • Publication number: 20240324906
    Abstract: A determination method is a determination method performed by a computer, and includes: instructing a target person to perform a specific action; capturing an image that includes, as a subject, the target person performing the specific action; estimating a skeletal model of the target person in the image based on the image captured; setting a plurality of three-dimensional regions around the skeletal model based on positions of a plurality of skeletal points in the skeletal model estimated; identifying, among the plurality of three-dimensional regions set, a three-dimensional region where a skeletal point of a wrist of the target person is located in the specific action; and determining a state of activities of daily living of the target person based on the three-dimensional region identified.

  • Publication number: 20240260854
    Abstract: A physical-ability estimation system (1) Includes: an analyzer (32) that estimates a gait feature of a user (U) from a moving image generated by capturing the user (U) walking; and an estimator (33) that estimates, based on the gait feature, respective assessment results on at least two assessment Items for assessing a physical ability of the user.

  • Publication number: 20240057946
    Abstract: A sarcopenia evaluation method in a sarcopenia evaluation device that evaluates sarcopenia based on a walking motion of a subject includes: acquiring walking data related to walking of the subject; detecting, from the walking data, at least one walking parameter of an angle of a knee joint of one leg in a stance phase of the one leg of the subject, an angle of the knee joint of the one leg in a swing phase of the one leg, a vertical displacement of a toe of one foot in the stance phase, a vertical displacement of the toe of the one foot in the swing phase, an angle of an ankle joint of the one foot in the stance phase, and an angle of the ankle joint of the one foot in the swing phase; and determining whether or not the subject has sarcopenia using at least one walking parameter.

  • Patent number: 11779260
    Abstract: A cognitive function evaluation method in a cognitive function evaluation device that evaluates a cognitive function based on a walking motion of a subject includes: acquiring walking data related to walking of the subject; detecting, from the walking data, at least one of an angle of an ankle joint of one foot and an angle of a knee joint of one leg of the subject; and determining a cognitive function level of the subject using at least one of the angle of the ankle joint and the angle of the knee joint.

  • Publication number: 20220257148
    Abstract: A factor estimation system is a factor estimation system that estimates a factor of fall risk indicating a possibility of a fall of a measured person, including: a calculator that obtains body motion data indicating body motion of the measured person during walking, and calculates two or more walking parameters of the measured person based on the body motion data obtained; and a factor analyzer that estimates, based on the two or more walking parameters, one or more main components that are included in the factor of the fall risk of the measured person and are based on the two or more walking parameters, and outputs an estimation result.
