Optimization Design Approach for User Experience of the Elderly APP Based on Kano Model and Conjoint Analysis

目的优化老年人APP用户体验,提出基于卡诺模型与联合分析的老年人APP用户体验优化设计方法。方法首先,建立老年人APP用户体验评价的指标体系,基于卡诺模型确定老年人对用户体验各指标的偏好权重。其次,确定APP的设计模式,选择合适的正交表确定设计模式的组合方式,建立高保真实验样本,邀请实验参与者使用实验样本执行典型任务,收集相关实验数据,并基于联合分析建立用户体验与设计模式之间的关系模型。最后,根据联合分析的结果确定最优设计,使用A/B测试对优化设计的结果进行验证。结论本文所提出方法可有效获取老年人对用户体验各指标的需求偏好,并对APP用户体验进行优化设计。

The work aims to propose an approach for the optimization design of user experience concerning the elderly APP based on Kano model and conjoint analysis,so as to optimize the user experience of the elderly APP.Firstly,the evaluation system of the user experience concerning the elderly APP was established,and the preference weight of the elderly for each index of user experience was derived by the Kano model.Secondly,the design patterns of APP were determined and the combination modes were ascertained based on a suitable orthogonal array.The high-fidelity experimental samples were made,and the experimental participants were asked to use these samples to execute typical tasks.The experiment data were collected,and then the relationship model between user experience and design patterns was developed by conjoint analysis.Finally,based on the results of conjoint analysis,the optimal design was obtained,and the corresponding results were verified by the A/B test.The proposed approach can effectively acquire the need preference of the elderly for user experience indexes and can achieve the optimization design concerning user experience of APP.
