DEVICE FOR MONITORING PSYCHOEMOTIONAL STATE OF USER AND METHOD FOR PROCESSING OBTAINED DATA Russian patent published in 2025 - IPC A61B5/16 A61B5/295 A61B5/533 A61B5/11 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine, namely to a wearable device for monitoring data indicative of a psychoemotional state of a user, and a method of analysing, processing and correcting said data. Device comprises a photoplethysmogram sensor, a microcontroller, an accelerometer, an electrodermal activity sensor and an analytical unit. Analytical unit is configured to generate data for assessing the psychoemotional state of the user based on sensor signals, with the possibility of preliminary analysis of data from sensors with determination of periods and levels of physical activity of the user and re-processing data in these periods when generating data for assessing the psychoemotional state of the user, as well as with the possibility of downsampling of the obtained signals. Data are pre-processed. Useful information is extracted from raw data. Periods of user movement are determined. In periods of user movement, preprocessing is repeated with additional data filtering algorithms. Useful information is re-extracted from raw data in periods of user movement. Extracted information is transmitted to a machine learning model or an analytical model. Psychoemotional state is classified based on the extracted information using a machine learning model or an analytical model. Graph of the psychoemotional state of the user is obtained.

EFFECT: broader capabilities of the device for monitoring the psychoemotional state of the user due to joint analysis of data from the accelerometer and a photoplethysmogram sensor for subsequent generation of user psychoemotional state evaluation data, and due to preliminary analysis to identify physical activity of the user, indicating noisy data, for their additional processing.
