| 目的 提升老年人对APP的满意度，帮助老年人更好地接受和使用APP。方法 提出基于故障树分析（FTA）的老年人APP交互设计方法。首先通过焦点小组确定导致错误发生的原因并建立故障树，对错误发生的原因进行合理分类；随后对故障树进行定性定量分析，计算故障树的最小切集和错误发生的概率，找到导致头号事件发生的核心因素；接着进行重要度分析，计算构造重要度，根据构造重要度值对引起错误发生的基本事件进行排序，为设计改良提供理论上的优先顺序；最后以老年人医疗APP为研究案例进行设计改良，并对改良后的结果进行错误率验证。结论 该方法可以有效地发现老年人操作APP时出现障碍的原因，不仅可以帮助设计师找到较为合理的改良方案，而且还可以使老年人获得良好的交互体验。 |

| The work aims to improve the elderly's satisfaction with APP and help them to accept and use it better. In-teraction design method of APP for the elderly based on fault tree analysis (FTA) was proposed. Firstly, the focus group determined the causes of the error and established the fault tree, and classified the causes of the error reasonably; then qualitatively and quantitatively analyzed the fault tree, calculated the minimum cut set of the fault tree and the probability of error occurrence, and found the core factors that led to the top events; then, the group carried out the importance analysis, calculated the structural importance, sorted the basic events that caused the errors according to the structural importance values, and provided the theoretical priority for the design improvement; finally, with the elderly medical APP as the research case, the design improvements were made and the error rates were verified for the improved results. The proposed method can effectively find out the causes for the obstacles in the operation of APP for the elderly. It can not only help designers find more reasonable improvement programs, but also enable the elderly to get a good interactive experience. |
