Abstract: Since the outbreak of the COVID-19 pandemic in 2020, the overall scale of the mask industry has grown significantly, and with the normalization of the pandemic, the mask market still has an expansion trend. However, the masks currently sold on the market are seriously homogeneous, and the combination of functionality and personalization is lacking. In order to adapt to the rapidly changing market demand, this study attempts to explore the application law of mask dividing line and find the mask structure design method that best meets the aesthetic requirements of the young.
Through market research, this paper classifies common masks on the market according to silhouettes, and identifies 16 experimental samples according to the combination of different dividing line elements. Through the questionnaire survey, the seven most popular masks and disposable medical masks were selected as the experimental styles. In order to simulate the wearing effect of different styles of masks in a more realistic manner, this study imprinted the mask in Fuyi CAD software, and exported the template for virtual stitching in 3DCLO to simulate the real wearing effect. Finally, eight physical masks made from black non-woven fabrics were used as the experimental samples for ERPs.
Through the event-related potential experiment, the EEG-induced condition of the participants viewing the pictures of eight masks was tested, and the subjects were invited to conduct subjective evaluation experiments after the EEG experiment. At the end of the experiment, data extraction and analysis were carried out. In this experiment, the influence of mask styles on aesthetic emotions was studied, with focus on visual response, so P300 components were selected as the research object, and the results were highly referenced. The multivariate repeated measurement of variance was used to comprehensively analyze the peak of P300 components caused by mask stimulation pictures in the Event-related potential study category.
Through experimental results, it can be seen that for the brain region, the frontal, central and parietal lobe induction is relatively obvious, and the crest induction mechanism of the parietal lobe is obviously related to various regions, especially the temporal lobe and occipital lobe. For hemispheres, the degree of induction in the left hemisphere is more obvious than that in the right hemisphere, but the difference effect is not obvious in the interaction between hemispheres. In terms of style, in addition to the most common disposable medical masks, masks with simple structure and horizontal comprehensive dividing lines are more favored by young people, which may provide a reference for the design and production of mask businesses. For the study of EEG components, the induction mechanism of P300 components is biased towards the degree of emotion production, rather than the type, and deeper liking emotions or deeper disgust will trigger P300 peaks with similar trends.
