    Abstract: A prediction device includes: a communication device that acquires measurement subject data including measurement data of a shape of a foot of a measurement subject person in a loaded state; a storage that stores first sample data in the loaded state and second sample data in an unloaded state, the first sample data and the second sample data being calculated from measurement data of foot shapes of a plurality of samples, the samples being identical both in the loaded state and the unloaded state; and a processor that predicts the shape of the foot of the measurement subject person in the unloaded state. The processor calculates a difference between the measurement subject data and the first sample data, and predicts the shape of the foot of the measurement subject person in the unloaded state based on the difference and the second sample data.

    Abstract: A prediction device includes: an input device that receives an input of measurement data of the foot shape of the person in a first loaded state, a processing circuitry is using a prediction model trained by machine learning to predict the foot shape of the person in a second loaded state in which a load is different from the first loaded state based on the measurement data received by the input device, and an output device that outputs prediction data of the foot shape of the person in the second loaded state predicted by the processing circuitry. The prediction model is generated in advance through training by machine learning based on training measurement data of a foot shape of a person for training in the first loaded state and training shape data of the foot shape of the person for training in the second loaded state.

    Abstract: A posture estimating device includes: at least one sensor attached to the person to be measured, the at least one sensor acquiring walking data based on an acceleration of three axes and an angular velocity of the three axes at at least one location of the person to be measured; a processing circuitry that estimates, using an estimation model trained by machine learning, the whole body posture of the person to be measured during the predetermined motion from the walking data acquired by the sensor; and an output device that outputs estimation data. The estimation model is generated in advance by training by machine learning based on the walking data acquired by the sensor during the predetermined motion and based on posture data obtained by measuring the whole body posture of the person to be measured at a timing when the walking data is acquired.
