基于眼动追踪的产品族设计基因识别强度研究

目的 对小米品牌产品族中多品类的产品设计开展案例研究，探索其设计基因的构成特性，研究分析产品设计基因的识别强度差异性，进而初步形成产品设计基因的提取及构建方法，以及识别强度分析方法。方法 首先构建产品设计基因识别强度对比方法，通过卡片分类法、聚类分析法和多维尺度分析法筛选出典型样本；其次由问卷分析和设计形态分析提取典型基因；最后结合眼动追踪和熵权法综合评价基因识别强度差异。结果 形成小米品牌产品（家电与智能类）因子库，包含通用型基因5项，专用型基因18项，且通用型基因的识别强度高于专用型基因。结论 初步构建了基于眼动追踪的产品族设计基因识别强度研究方法，可以此作为基础规划及管理产品设计方案，使产品设计兼顾品牌基因的延续性及单品设计的合理性；同时还可为生态链企业研发同品牌、不同品类产品提供设计策略与参考。

Identification Strength of Product Family Design Gene Based on Eye Tracking

The work aims to carry out a case study of product design for multiple categories of Xiaomi product families, explore the composition characteristics of its design genes, study and analyze the difference in identification strength of product design genes, and then form a preliminary method of product design gene extraction and construction, as well as an identification strength analysis method. A product design gene recognition strength comparison method was constructed. Typical samples were selected by the card classification method, the cluster analysis method and the multi-dimensional scale analysis method; Then typical genes were extracted by the questionnaire and design form analysis method; Finally the gene recognition strength differences were comprehensively evaluated by combining the eye tracking and the entropy weight method. A factor library of Xiaomi products (home appliances and smart category) was formed, containing 5 generic genes and 18 specialized genes, and the identification intensity of generic genes was higher than that of specialized genes. A research method for product family design gene identification strength is preliminarily developed based on eye tracking. It can be used as a basis for planning and managing product design solutions, so that the product design can take into account the continuity of brand genes and the rationality of individual product design. It can also provide design strategies and references for ecological chain companies to develop different product categories of the same brand.
