Research on the Construction of Product Material Perceptual Evaluation Model Based on EEG Physiological Cognition

摘要

In order to improve the user experience of industrial product materials and solve the problems of strong subjectivity and lack of objective data support in the evaluation of industrial product materials, a perceptual evaluation method of product materials based on EEG is proposed, and a comprehensive model of perceptual evaluation of industrial product materials combining psychological and physiological evaluation indexes is established. 20 subjects were recruited to carry out perceptual evaluation tests on 8 kinds of teacups made of different materials, and the established model was calculated mathematically to select the optimal material scheme. The experimental results verified the effectiveness of the model, indicating that the psychological and physiological indexes of users can be mutually verified in the perceptual evaluation of product materials.
