Study On The High-heels Comfort Evaluation Method-Based On EEG Technology

The wearing comfort of high-heeled shoes is determined by both human physical and psychological aspects.EEG technology as a kind of psychophysiological research technology can combine the physical and psychological indicators in the evaluation of high-heeled comfort,for high-heeled shoes.Comfort evaluation provides an effective evaluation tool that integrates physiological psychology.This study selected 55 people,both of them are 24-27 years old women,they have equivalent education levels,both of them are 37~#.We can obtain the pressure distribution of heels through Novel Pedar;the subjects were evaluated by subjective wearing using the SD measurement method during the test.Correlation with heel height;the brain electrical rhythm characteristics of static standing and uniform natural walking state were tested by BP EEG signal acquisition system,and the EEG characteristics of the subjects wearing 6 different heel shoes were obtained.Correlation analysis was carried out by EEGLAB and mathematical analysis software SPSS,which were related to high,subjective evaluation,plantar pressure distribution and EEG power value.Research result:(1)With the increase of the height of women's shoes,the peak pressures of the soles T1,T2-5 and M1 increased significantly,and the alpha wave of EEG showed a downward trend,and the subjective discomfort increased.There was a positive correlation between the height of the heel and the peak pressure of the sole,and a negative correlation with the alpha power value of the brain.(2)30 electrodes in different states shows that the change of plantar pressure under the action of high heel has an effect on brain waves,and the peak pressure of the foot suppresses the alpha wave of brain electricity,making people in a kind of Uncomfortable state.(3)The brain regions activated by the somatosensory stimulation produced by wearing different high-heeled shoes are mainly the top zone and the occipital zone.In the subsequent study,the electrodes FPz,F3,F4 and Oz of the brain regions of the top zone and the occipital zone can be regarded as the main Observe the electrode and study it in depth.The research results of EEG technology as a means to measure the comfort of high-heeled shoes can compensate for the lack of subjective evaluation methods,improve the wearing comfort evaluation system of footwear,and have important theoretical and practical significance for the evaluation of footwear comfort.
