Interacting with mobile applications can often be challenging for people with visual impairments due to the poor usability of some mobile applications. The goal of this paper is to provide an overview of the developments on usability of mobile applications for people with visual impairments based on recent advances in research and application development. This overview is important to guide decision-making for researchers and provide a synthesis of available evidence and indicate in which direction it is worthwhile to prompt further research. We performed a systematic literature review on the usability of mobile applications for people with visual impairments. A deep analysis following the Preferred Reporting Items for SLRs and Meta-Analyses (PRISMA) guidelines was performed to produce a set of relevant papers in the field. We first identified 932 papers published within the last six years. After screening the papers and employing a snowballing technique, we identified 60 studies that were then classified into seven themes: accessibility, daily activities, assistive devices, navigation, screen division layout, and audio guidance. The studies were then analyzed to answer the proposed research questions in order to illustrate the different trends, themes, and evaluation results of various mobile applications developed in the last six years. Using this overview as a foundation, future directions for research in the field of usability for the visually impaired (UVI) are highlighted.
对于视力障碍者而言，由于一些移动应用程序的可用性较差，与它们进行交互往往具有挑战性。本文的目的是基于研究和应用开发的最新进展，概述针对视力障碍者的移动应用程序可用性方面的发展情况。这一概述对于指导研究人员的决策很重要，能综合现有证据，并指出值得推动进一步研究的方向。我们对针对视力障碍者的移动应用程序的可用性进行了系统的文献综述。按照系统评价和荟萃分析的首选报告项目（PRISMA）指南进行了深入分析，以得出该领域的一组相关论文。我们首先确定了过去六年内发表的932篇论文。在筛选这些论文并采用滚雪球技术后，我们确定了60项研究，然后将其分为七个主题：可访问性、日常活动、辅助设备、导航、屏幕划分布局和音频指导。然后对这些研究进行分析，以回答提出的研究问题，从而阐明过去六年中开发的各种移动应用程序的不同趋势、主题和评估结果。以这一概述为基础，突出了视障用户可用性领域未来的研究方向。
