基于遗传算法的老年人APP用户体验优化设计方法

为了提高老年人智能手机APP的用户体验，提出基于遗传算法的老年人APP用户体验优化设计方法。首先采用文献研究法和焦点小组法确定老年人APP的设计模式，并基于正交设计原则设计APP的试验样本，接着建立用户体验评价体系，运用层次分析法确定评价指标的权重，再由数量化理论Ⅰ建立APP设计模式与用户体验之间的量化关系，最后运用遗传算法得到最优设计方案。本文以老年人移动支付APP为例进行研究，结果表明所提出的方法能够有效地对老年人APP的用户体验进行优化设计。

An Optimization Design Method for APP User Experience of the Elderly Based on Genetic Algorithm

In order to improve the user experience (UX) of the smartphone application (APP) for the elderly, an optimization design method for APP UX of the elderly based on genetic algorithms is proposed. Firstly, literature research and focus group are employed to determine the design patterns of the elderly APP, and APP experimental samples are designed on the basis of the orthogonal design principles. Subsequently, a UX evaluation system is established, and analytic hierarchy process is used to determine the weights of UX evaluation criteria. After that, quantitative relationship between APP design patterns and users experience is built by using quantification theory type 1. Finally, genetic algorithm is adopted to obtain an optimal design solution. The mobile pay APP for the elderly is used as a case study, and the results suggest that the proposed method can effectively optimize the design for UX of the elderly APP.
