Concentration assessment and training guidance system based on multiple physiological signals

Abstract

The invention provides a concentration assessment and training guidance system based on multi-physiological signal fusion, which is characterized in that an electroencephalogram signal, a heart rate signal and a blood oxygen signal are acquired by a non-invasive brain-computer device, and time synchronization and data preprocessing are performed on the acquired multi-source physiological signals; a multi-signal fusion evaluation module in the system performs fusion calculation on the preprocessed signals to generate a concentration evaluation result of the user; the concentration judgment module judges the concentration state of the user based on the evaluation result, and provides personalized training suggestions through the training guidance module; the system also has a closed-loop feedback mechanism, and can adjust the training content, strength and duration in real time according to the change of the concentration state. In addition, different evaluation and training strategies can be adopted according to the characteristics of different application crowds (such as students and old people), and the method has high scene adaptability and practical value.
