Problems solved by technology

[0003] Traditional fabric tactile texture characterization methods mainly describe the subjective feeling of people in contact with fabrics through qualitative language. This evaluation method is greatly affected by individual cognitive differences, and the rigor, stability and universality of the evaluation results are weak.

Abstract

The invention discloses a fabric tactile sensation quantitative evaluation and recognition system based on a multi-mode brain-computer interface, and relates to the technical field of fabric evaluation. The system comprises an electroencephalogram collecting cap, a near-infrared brain function imager, a sample table, a processing module and a display module. The invention discloses a fabric tactile sensation quantitative evaluation and recognition system based on the multi-mode brain-computer interface, by which the touch sensation texture electroencephalogram signals and the blood oxygen concentration when a human body touches the fabric can be acquired in real time; the processing module is used for analyzing and extracting characteristic parameters and obtaining the brain activation degree, the characteristic parameters and the brain activation degree are combined, the quantitative evaluation of touch sensation such as fabric comfort and smoothness is achieved, and the recognition of the fabric is completed by comparing and classifying the touch sensation with electroencephalogram characteristic parameters of different fabrics. The evaluation and recognition system can reflect the real tactile sensation reflection of the brain of the human body, objectively achieves the quantitative evaluation of the tactile sensation of the fabric by people, improves the accuracy and objectivity of evaluation, and reduces the number of processing channels.

Description

technical field [0001] The invention relates to the technical field of fabric recognition and evaluation, in particular to a quantitative evaluation and recognition system for fabric tactile texture based on a multimodal brain-computer interface. Background technique [0002] People usually perceive the texture of fabrics through touch, and the tactile texture of fabrics determines consumers' recognition and satisfaction with products, and is a key factor in the design, production and sales of textiles. [0003] Traditional fabric tactile texture characterization methods mainly describe the subjective feeling of people in contact with fabrics through qualitative language. This evaluation method is greatly affected by individual cognitive differences, and the rigor, stability, and universality of the evaluation results are weak. [0004] Therefore, in view of the above problems, it is necessary to propose a quantitative evaluation and recognition system for fabric tactile tex...
