基于Kano-QFD的云养宠APP可用性设计研究

Usability Optimization Design of Cloud Pet APP Based on Kano-QFD

目的通过挖掘云养宠人群的需求,分析用户需求和功能要求之间关系,来获取功能要求的绝对权重,并基于功能要求的权重设计出既满足养宠者需求,且具有良好可用性的云养宠APP。方法将Kano-QFD组合模型作为云养宠APP的可用性研究方法。通过调研来收集养宠者的用户需求,利用Kano模型分析云养宠APP的用户需求要素及其重要度;对用户需求分析解剖获得对应的功能要求,并将两者导入QFD模型中,评估需求与功能矩阵的相关程度,从而得出与需求相关度较高的功能要求;将功能要求作为设计依据,结合EPO可用性模型优化设计内容,进行云养宠APP的信息架构、交互原型和视觉界面设计,并用眼动实验和SUS可用性调查验证模型可靠性。结论通过构建Kano-QFD可用性设计模型,来进行用户需求分析、用户需求到功能要求的转化、以功能要求为基础展开详细设计步骤的层层转换,实现了云养宠APP的可用性设计,也为相似问题提供了解决思路。

By exploring the needs of cloud pet people, analyzing the relationship between user needs and functional requirements, the absolute weight of functional requirements is obtained. Based on the weight of functional requirements,a cloud pet app with good usability is designed to meet the needs of pet people. Kano-QFD combination model is used as the usability research method of cloud pet app. Through the investigation and collection of pet users’ needs, this paper uses Kano model to analyze the user needs elements and their importance of cloud pet app;dissects the user needs to obtain the corresponding functional requirements, and imports them into the QFD model to evaluate the correlation between the needs and the functional matrix, and obtains the functional requirements with higher correlation with the needs;the functional requirements are taken as the design basis, and the content of the design is optimized in combination with the EPO usability model. The information architecture, interactive prototype and visual interface of cloud pet app are designed. The reliability of the model is verified by eye movement experiment and SUS usability survey. Through the construction of Kano-QFD usability design model, the user needs analysis, the transformation of user needs to functional requirements, and the layer by layer transformation of detailed design steps based on functional requirements, the usability design of cloud pet app is realized, and the solution to similar problems is also provided.
