基于Logistic回归的老年人APP用户体验优化设计

目的 提升老年人APP的用户体验水平。方法 提出一种基于Logistic回归的老年人APP用户体验优化设计研究方法。首先，通过文献研究和焦点小组法确定APP的设计模式，并选择合适的正交表确定设计模式的组合方式；其次，构建以行为体验、感知体验和情感体验为基础的用户体验评价体系，邀请被试者对试验样本执行具有代表性的任务，并对用户体验进行评价研究，收集试验数据；再次，运用序次Logistic回归建立APP设计模式与用户体验之间的关系模型，确定APP的最佳设计方案；最后，运用A/B测试方法对得到的试验结果进行验证。结论 以老年人移动医疗APP为例进行研究，结果表明所提出的方法可以有效地对老年人APP的用户体验进行优化设计，有助于设计师了解老年用户的偏好，设计出适合老年人使用的APP。

Optimization Design of Elderly APP User Experience Based on Logistic Regression

In order to improve the user experience level of mobile APP for the elderly. A research method based on Logistic Regression for the optimization design of the user experience of the elderly APP is proposed. Firstly, determine the design mode of APP through literature research and focus group method, and select the appropriate orthogonal table to determine the combination of design modes; Secondly, build a user experience evaluation system based on behavioral experience, perceptual experience, and emotional experience, and invite participants to perform representative tasks on the test samples, conduct evaluation studies on user experience, and collect test data;Then, use Ordinal Logistic Regression to establish the relationship model between APP design mode and user experience, and determine the best design plan of APP; Finally, the A/B test is used to verify the obtained test results. Taking the mobile medical APP for the elderly as an example, the result shows that the proposed method can effectively optimize the user experience of the elderly APP, which helps designers understand the preferences of elderly users and design an APP suitable for the elderly.
