This research aimed to develop a comprehensive evaluation of the mobile user interface abilities of the elderly so that technology can be designed to meet individualized needs. A total of 135 older adults were evaluated with the developed system, the Elderly Mobile User Interface Ability Evaluation System (EMUIAES). The prediction of age and the use of technology on elderly mobile interface usage were investigated based on the findings of the evaluation. The relationship between performance on Fitts' task and elderly mobile user interface ability (EMUIA) was also examined. The findings showed a strong effect of age on the elderly's use of mobile user interfaces. Previous experience with personal and tablet computers also contributed to the use of mobile user interfaces. In addition, this research demonstrated the application of Fitts' law to describe the elderly mobile user interface behaviors, particularly for tasks involving fast tapping and pointing. The EMUIAES can provide future researchers and designers a comprehensive tool to describe the elderly's diverse behaviors and changes in their ability to use mobile interfaces. Individualized interface designs for elderly users can be developed based on these findings to improve the elderly users' experiences of using technology.

这项研究旨在对老年人的移动用户界面功能进行全面评估，以便可以设计出满足个性化需求的技术。共有135名老年人使用开发的系统，即老年人移动用户界面能力评估系统（EMUIAES）进行了评估。根据评估结果，研究了年龄预测和技术对老年人移动界面使用的影响。还研究了Fitts任务的绩效与老年人移动用户界面功能（EMUIA）之间的关系。研究结果表明，年龄对老年人使用移动用户界面的影响很大。以前使用个人和平板电脑的经验也有助于使用移动用户界面。此外，这项研究还证明了Fitts' 描述老年人移动用户界面行为的法律，特别是涉及快速点击和指向的任务。EMUIAES可以为未来的研究人员和设计人员提供一个全面的工具，以描述老年人的各种行为以及他们使用移动界面的能力的变化。可以根据这些发现来开发针对老年人的个性化界面设计，以改善老年人使用技术的体验。
