Smartphone-based self-testing could facilitate large-scale data collection and remote diagnostics. For this purpose, the matrix sentence test (MST) is an ideal candidate due to its repeatability and accuracy. In clinical practice, the MST requires professional audiological equipment and supervision, which is infeasible for smartphone-based self-testing. Therefore, it is crucial to investigate the feasibility of self-administering the MST on smartphones, including the development of an appropriate user interface for the small screen size.
We compared the traditional closed matrix user interface (10 × 5 matrix) to three alternative, newly-developed interfaces (slide, type, wheel) regarding SRT consistency, user preference, and completion time.
We included 15 younger normal hearing and 14 older hearing-impaired participants in our study.
The slide interface is most suitable for mobile implementation, providing consistent and fast SRTs and enabling all participants to perform the tasks effectively. While the traditional matrix interface works well for most participants, some participants experienced difficulties due to its small size on the screen.
We propose the newly-introduced slide interface as a plausible alternative for smartphone screens. This might be more attractive for elderly patients that may exhibit more challenges with dexterity and vision than our test subjects employed here.
基于智能手机的自我测试有助于大规模数据收集和远程诊断。出于这个目的，矩阵句子测试（MST）因其可重复性和准确性成为理想选择。在临床实践中，MST需要专业的听力学设备和监督，这对于基于智能手机的自我测试是不可行的。因此，研究在智能手机上自行进行MST的可行性至关重要，包括为小屏幕尺寸开发合适的用户界面。
我们将传统的封闭式矩阵用户界面（10×5矩阵）与三种新开发的替代界面（滑动、打字、转轮）在言语识别阈（SRT）一致性、用户偏好和完成时间方面进行了比较。
我们的研究纳入了15名年轻听力正常者和14名老年听力受损者。
滑动界面最适合在移动设备上使用，能提供一致且快速的SRT，并使所有参与者都能有效地完成任务。虽然传统矩阵界面在大多数参与者中运行良好，但一些参与者因屏幕上其尺寸较小而遇到困难。
我们建议将新引入的滑动界面作为智能手机屏幕的一个合理替代方案。对于可能比我们这里所使用的测试对象在灵活性和视力方面面临更多挑战的老年患者来说，这可能更具吸引力。
