INFORMATION TERMINAL DEVICE, A SYSTEM FOR COLLECTING MOTION DATA AND A METHOD FOR COLLECTING MOTION DATA Russian patent published in 2021 - IPC A61B5/11 

FIELD: medical equipment.

SUBSTANCE: group of inventions relates to medical equipment, namely, a system and method for collecting motion data. The motion data collection system, which detects the user's body motions, contains body motion sensors, plantar sensors, a body motion recording unit, a body motion calculation unit, a correction unit, an analysis unit, and an output device. Body motion sensors are attached to the user's body parts to measure the three-dimensional motion and acceleration of each of these body parts. Plantar sensors are attached to the soles of the user's shoes to measure the pressure exerted on the soles. Each body motion sensor and plantar sensors are equipped with a wireless communication unit and are grouped into a group of sensors by a wireless communication unit. The body motion recording unit is designed to accumulate data from the measurement results of body motion sensors and plantar sensors as data on body motions. The body motion calculation unit is designed to calculate the user's body motions as data for reproducing body motions based on the measurement results of the body motion sensors and the relative relative position between the body motion sensors. The correction unit is made with the ability to correct the data for reproducing body motions calculated by the body motion calculation unit, based on the data of the measurement results of plantar sensors. The analysis unit is designed to analyze the user's body motions based on the data for reproducing the body motions corrected by the correction unit. The output device is made with the ability to display or output the data of the analysis results of the analysis block. In another embodiment, the system that detects the motions of the user's body contains body motion sensors attached to the left and right parts of the user's body, a cycle extraction unit. The cycle extraction unit is designed to extract cycle changes from body motions based on the data for reproducing body motions accumulated in the body motion recording unit. The correction block is designed to correct the data for reproducing the body motion calculated by the body motion calculation block based on the cyclic change data. When performing a method of collecting motion data to detect the motions of the user's body, the three-dimensional motions and accelerations of the user's body parts and the pressure exerted on the soles of the user's shoes are measured. Body motions are recorded to accumulate the measurement results of body motion sensors and plantar sensors as body motion data in the body motion data recording unit. Data are generated for reproducing body motions as data for reproducing body motions based on the measurement results of body motion sensors. The data are adjusted for reproducing body motion, which are calculated by the body motion calculation unit, the correction unit based on the measurement results of the plantar sensors. The user's body motions are analyzed by the analysis unit based on the data to reproduce the body motions corrected at the data correction stage. Data or output analysis results are displayed using an output device. In another variant of the method, the motions and accelerations of body parts are measured using body motion sensors. Using the cycle extraction unit, the cyclic change data is extracted from the body motions based on the body motion reproduction data accumulated in the body motion recording unit. The data for reproducing the body motion, which are calculated by the body motion calculation unit, are adjusted using the correction unit, based on the cyclic change data.

EFFECT: system and method to collect motion data for detecting the user's body motion are provided, which makes it possible to monitor the execution of exercises by the user, as well as identifying the causes of deterioration in the exercise technique by analyzing the parameters of the exercise technique.
