| 目的 探究不同任务场景下老年用户对操作界面导航的适用性。方法 结合SOC理论与任务评估模型，建立了老年用户界面导航SOC-TM模型可用性评估方法。通过对30位受试者进行面对面的可用性测试，测量了老年用户在不同任务场景下，任务完成度指标、任务绩效指标，以及操作界面导航的主观满意度测评指标。结果 老年用户的任务正确率相比青年用户明显较低;在完成任务的时间上，老年用户与青年用户并无显著区别;老年用户使用列表与抽屉导航模式时，任务完成时间波动大，操作稳定性较低;老年用户的主观满意度评价指标低于青年用户，并且老年用户的SOC自我评价量表得分与任务正确率呈正相关关系，与任务完成时间呈负相关关系。结论 在适老化界面导航的可用性评估与设计改进中，应充分评估老年用户的操作能力，根据操作能力的不同，匹配不同类型的界面导航模式，用多维度指标对界面导航进行评估与设计改进，并考虑不同应用程序之间的可用性互通原则。 |

| Abstract: |
| The work aims to investigate the applicability of user interface navigation for elderly users under different task scenarios. The SOC theory and the task evaluation model were combined to establish a usability evaluation method for the SOC-TM model of elderly user interface navigation. Based on a face-to-face usability test on thirty subjects, the task completion indicator, task performance indicator and subjective satisfaction evaluation indicator of elder users' operation interface navigation under different task scenarios were measured. The task correctness rate of elderly users was significantly lower than that of young users. There was no significant difference in task completion time between elderly users and young users. When elderly users used list and drawer navigation, the task completion time fluctuated greatly, and the stability of operation was low. The subjective satisfaction evaluation indicator of elderly users was lower than that of young users, and the SOC self-evaluation scale scores of elderly users were positively correlated with task correctness and negatively correlated with task completion time. In the usability evaluation and design improvement of elderly-oriented interface navigation, the operation ability of elderly users should be fully evaluated. Different types of interface navigation modes should be matched according to different operational abilities. Multi-dimensional indicators should be used to evaluate and improve the design of interface navigation, and the principle of usability interoperability between different applications should be considered. |
