Purpose

This study aims to develop a ubiquitous library for the visually impaired (ULVI) application (app) and to explore its usability by collecting feedback from visually impaired participants to analyse the problems they might encounter. Their suggestions for improving the app further are also reported.

Design/methodology/approach

A total of ten participants were recruited in the study. Ten tasks were assigned for the participants to complete using the ULVI app. The system usability scale was adopted to collect feedback on the app, and interviews were conducted to understand the participants’ usage behaviours and perceptions of the app.

Findings

The findings indicated that the participants provided positive evaluation of the usability of the app and addressed the functions that might need improvement. Above all, this app was regarded as having great potential. Suggestions and improvements are proposed based on the participants’ feedback.

Originality/value

In terms of the studies relevant to libraries and the visually impaired, few have evaluated the usability of the ULVI app from the perspectives of the visually impaired users. The ULVI app provides resources for the visually impaired and serves as the foundation for developing a more effective ULVI app.

促进视力障碍者的学习：专门设计的无处不在的图书馆的开发和可用性评估

目的

这项研究旨在为视障人士（ULVI）应用程序（app）开发一个无处不在的库，并通过收集视障人士的反馈以分析他们可能遇到的问题来探索其可用性。他们还提出了进一步改进该应用程序的建议。

设计/方法/方法

该研究共招募了十名参与者。分配了十项任务供参与者使用ULVI应用程序完成。采用系统可用性量表来收集有关该应用程序的反馈，并进行了访谈以了解参与者的使用行为和对该应用程序的看法。

发现

调查结果表明，参与者对应用程序的可用性提供了积极的评估，并解决了可能需要改进的功能。最重要的是，该应用程序被认为具有巨大的潜力。根据参与者的反馈提出建议和改进。

创意/价值

在与图书馆和视障人士有关的研究方面，很少有人从视障用户的角度评估ULVI应用程序的可用性。ULVI应用程序为视障人士提供了资源，并为开发更有效的ULVI应用程序奠定了基础。
