Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Electroencephalogram (Electroencephalogram, EEG) is when the brain is active, a potential difference is formed between the cerebral cortex cell groups, thereby generating an electric current outside the cerebral cortical cells. It records the electric wave changes during brain activity, which is the overall reflection of the electrophysiological activities of brain nerve cells on the surface of the cerebral cortex or scalp.

[0024] According to its frequency, brain waves include: alpha wave (7-14Hz), beta wave (14-30Hz), and theta wave (4-7Hz). EEG signals contain rich content including th...

Abstract

The invention relates to the medical data field, and provides a human body emotion and fatigue state assessment method and system based on brain waves; the method comprises the following steps: using an electrode sensor to gather human body brain waves, and obtaining a brain wave signal according to the brain waves; carrying out Fourier transform on the brain wave signal so as to obtain frequency range energy of the corresponding frequency range; obtaining individual emotion and fatigue state characteristic constants according to the frequency range energy of the corresponding frequency range, wherein the emotion and fatigue state comprises reaction intensity on stimulation, like / dislike reactions on an event, and fatigue level. The method can calculate so as to obtain present emotion and fatigue state characteristic constants of a to-be-assessed individual, can quantify human body brain waves so as to represent present motion status, concentration level and relaxation level, thus assessing emotion and fatigue state with pertinency, reducing misjudgement rate, and accurately assessing self motion and fatigue state.

Description

technical field [0001] The invention relates to the field of medical data, in particular to a method and system for evaluating human emotions and fatigue states based on brain waves. Background technique [0002] Generally, there are two methods for the identification of human emotions: classification approach method and dimension approach method. The theory based on the classification approach method is to classify emotions into six types, which are anger, disgust, fear, sadness, happiness and fright; the dimension approach method is to distinguish emotions by dimensions, namely pleasure / disgust, excitation / inhibition, tense / relaxed. The model of the dimensional approach method is divided into two-dimensional and three-dimensional models, such as figure 1 , which is a two-dimensional dimensional approach model, with the response intensity to the stimulus as the vertical axis and the response to the event as the horizontal axis to form a coordinate axis. The origin of the ...
