目的 为视障群体精准设计商场出行辅助产品,提升购物体验与生活品质。方法 在问题识别阶段,通过问卷调查法、访谈法等方式获取用户的原始需求;采用非参与式行为观察法对视障群体的商场购物行为进行深度分析,挖掘潜在需求;利用KANO模型量化评估用户需求属性,获得需求优先级;进一步采用FAST功能分析系统技术将用户需求转化为功能后,逐级拆解复杂功能为子功能;采用融合感官代偿方法的FBS模型,一方面实现了产品功能到结构参数的合理映射,另一方面实现了其他感觉器官替代视觉的形式,进而得到产品的各个结构模块,输出最终设计方案。结果 根据这个设计流程方法,设计出了符合视障群体用户需求的商场出行辅助产品,提高了用户的生活质量。结论 基于KANO/FAST/ FBS设计流程,以视障群体商场出行辅助产品为对象进行研究,验证了该设计方法的有效性,为特殊群体出行产品的设计和研究提供了参考。
Abstract
The work aims to precisely design shopping assistance products for the visually impaired group in malls, to enhance the shopping experience and quality of life. During the problem identification stage, the original needs of users were obtained through methods such as questionnaire surveys and interviews. Subsequently, the non-participatory behavior tracking method was used to conduct in-depth analysis of the shopping behaviors of the visually impaired group in malls, to identify potential needs. Then, the KANO model was utilized to quantitatively evaluate the attributes of user needs and obtain the priority of the needs. Further, the FAST function analysis system technology was employed to convert user needs into functions, and then the complex functions were decomposed into sub-functions step by step. Finally, the FBS model with sensory compensation integration method was adopted to achieve a reasonable mapping of product functions to structural parameters, and to realize the form of substituting other sensory organs for vision, thereby obtaining the various structural modules of the product and outputting the final design scheme. Based on this design process method, shopping assistance products that met the needs of visually impaired users were designed, improving the quality of life of users. Based on the KANO/FAST/FBS design process, the research is conducted on the shopping assistance products with the visually impaired group as the object, verifying the effectiveness of this design method, and providing a reference for the design and research of travel products for the special group.
