Abstract

Introduction. This study compares 30 blind and visually impaired users’ assessment of accessibility and usability of the two mobile platforms (mobile app and mobile web) of a digital library. Method. Triangulation of data collection was applied, including interviews, think-aloud protocols, transaction logs, post-platform interviews, and post-search interviews. Analysis. Two steps of analysis were used. First, quantitative analysis was applied to compare assessments of participants towards two mobile platforms’ accessibility and usability. Second, qualitative data were analysed to identify types of design factors. Results. Mobile app performs significantly better in all accessibility and usability variables except accessing information/objects. Most importantly, nine types of design factors are revealed in relation to blind and visually impaired users’ assessment of accessibility and usability for the two mobile platforms. Furthermore, the design problems of Mobile Web are associated with a responsive design that adjusts the digital library interface to a mobile device, the complexity of digital library structure and formats, and a sight-centred design that excludes blind and visually impaired users’ unique information-seeking behaviours. Conclusion. Mobile platforms of digital libraries, especially mobile web, need to improve their designs. Design implications for mobile web are further discussed.
移动平台数字图书馆可及性与可用性比较:盲人与视障用户评价
介绍。本研究比较了30名盲人和视障用户对数字图书馆两个移动平台(移动应用程序和移动网页)的可访问性和可用性的评估。& # x0D;方法。数据收集采用了三角测量,包括访谈、出声思考协议、事务日志、平台后访谈和搜索后访谈。 分析。采用了两步分析方法。首先,采用定量分析来比较参与者对两个移动平台的可访问性和可用性的评估。其次,对定性数据进行分析,确定设计因素的类型。 结果。除了访问信息/对象,移动应用在所有可访问性和可用性变量上都表现得更好。最重要的是,我们揭示了与盲人和视障用户对两个移动平台的可访问性和可用性的评估相关的九种设计因素。此外,移动Web的设计问题与响应式设计有关,响应式设计使数字图书馆界面适应移动设备,数字图书馆结构和格式的复杂性,以及以视觉为中心的设计,排除了盲人和视障用户独特的信息寻求行为。& # x0D;结论。数字图书馆的移动平台,尤其是移动web平台的设计还有待改进。进一步讨论了移动网络的设计含义。
