面向产品造型风格的用户认知模式及量化模型研究

Research on User Cognition Pattern and Its Quantitative Model Oriented to Product Modeling Styles

针对产品造型设计过程中存在的主观感性认知偏见问题,提出一种面向产品造型风格的用户认知模式及量化模型。首先对产品造型风格中的特征元素进行显著性分析,并结合"风格曲线"及特征线概念探究了特征元素收敛至线性轮廓的用户认知模式;继而在特征整合的基础上提出产品造型风格的一般认知模式,即伴随着用户认知的不断深化,产品造型风格在用户头脑中将逐渐收敛至产品特征元素的线性轮廓;最后结合MATLAB相关系数概念提出特征元素线性轮廓的量化模型,为产品设计提供客观、理性的决策依据。以中国高速列车CRH380系列产品造型进行眼动跟踪实验,验证了该理论模型的可行性。

Aiming at the problem of subjective perceptual bias in the process of product design, this paper presents a user cognitive model and quantification model for product modeling style. Firstly, the Significance analysis of the feature elements in the product modeling style is analyzed, and the user cognitive model of the convergence of the characteristic elements to the linear contours is explored in combination with the concept of “style curve” and the characteristic line. Then, based on the feature integration, general cognitive model, that is, with the continuous deepening of user awareness, product modeling style in the user’s mind will gradually converge to the product characteristics of the linear contours. Finally, a quantitative model of linear contours of feature elements is proposed based on the concept of MATLAB correlation coefficient, which provides objective and rational decision-making basis for design activities. In this paper, the eye movement tracking experiment of CRH380 series of high speed train in China is carried out to verify the feasibility of the theoretical model.
