倾斜角手势与传统界面导航技术在移动数字图书馆中的应用对比研究

[目的/意义] 通过采用高效能的界面导航技术,部分解决在移动数字图书馆的使用过程中存在的用户交互绩效低、使用体验差的问题,以提高移动数字图书馆被使用时的交互绩效、易用性及对多样化应用场景的适用性。[方法/过程] 以实际的数字图书馆资源定位操作为实验任务,通过定量实验收集所采用的界面导航技术和传统的导航技术在完成实验任务过程中的任务完成时间、准确率及被试者的主观评价等方面的数据;在SPSS 25中,采用RM-ANOVA对实验数据进行统计分析。[结果/结论] 所采用的界面导航技术相对于传统的导航技术在实验任务完成效率方面提高了68%,准确率提高了29%;在被试者反映的主观偏好和眼疲劳方面均显著优于传统技术;所采用的技术支持单手操作和"盲操作",比传统技术能更好地适应移动数字图书馆多样化的应用场景。

A Comparative Study of Tilting-Gesture-Based and Traditional Interfacial Navigational Techniques for Mobile Digital Libraries

[Purpose/significance] We proposed an efficient interfacial navigational technique for mobile digital libraries(MDLs) to partially overcome their drawbacks of low interaction performance and poor user experience, and enhance ease of use and usefulness of MDLs.[Method/process] A quantitative experiment was conducted to compare the two interfacial navigational techniques, i.e. the proposed and the traditional. Together with subjective data of personal preference and eye-fatigue from the subjects, the average time and accuracy per trial to locate the given digital resources of the practical digital library of Lanzhou University were gathered. The experimental data were analyzed by RM-ANOVA in SPSS 25.[Result/conclusion] The proposed technique has improved navigational efficiency by 68% over the traditional one, and accuracy by 29%; furthermore, the proposed technique is suitable for multiple application contexts of MDLs since it supports unimanual and eye-free operations.
