基于灰色层次分析法的老年人APP 用户体验评价研究

为了提高老年人APP 的用户体验水平，提出一种基于灰色层次分析法(AHP)的老 年人APP 用户体验评价模型。首先，构建用户体验的评价体系；接着，通过AHP 计算评价指 标的权重；最后，采用灰色关联分析法(GRA)将用户体验的评价指标整合为灰色关联度，从而 根据灰色关联度选择最优方案。以移动医疗APP 作为案例，结果表明基于灰色AHP 的APP 用 户体验评价模型可以有效地评价老年人APP 的用户体验水平，为设计决策提供依据。

Research on the User Experience Evaluation of APP for the Elder Based on Grey AHP

To improve user experience (UX) level for the elder, this paper proposes an evaluation model of UX of APP for the elder based on grey analytic hierarchy process (AHP). Firstly, an evaluation system is built. Second, the elderly preference weights for evaluation indexes are investigated by AHP. Finally, the criteria of UX are integrated into grey relational grade by using grey relational analysis (GRA) to obtain optimal design. A mobile health application was chosen as a case study. The result indicates that the grey AHP-based evaluation model can be used to evaluate the UX level of APP for the elder effectively, and designers can achieve insights for decision making of design.
