Abstract

Since the first lockdown in 2020, video conferencing tools have become increasingly important for employment, education, and social interaction, making them essential tools in everyday life. This study investigates the accessibility and usability of the desktop and mobile versions of three popular video conferencing tools, Zoom, Google Meet, and MS Teams, for visually impaired people interacting via screen readers and keyboard or gestures. This involved two inspection evaluations to test the most important features of the desktop and mobile device versions and two surveys of visually impaired users to obtain information about the accessibility of the selected video conferencing tools. Sixty-five people answered the survey for desktop and 94 for mobile platforms. The results showed that Zoom was preferred to Google Meet and MS Teams but that none of the tools was fully accessible via screen reader and keyboard or gestures. Finally, the results of this empirical study were used to develop a set of guidelines for designers of video conferencing tools and assistive technology.

视频会议工具:屏幕阅读器用户体验的比较研究和更具包容性的设计指南的发展

自2020年首次封锁以来，视频会议工具在就业、教育和社交方面变得越来越重要，成为日常生活中必不可少的工具。本研究调查了三种流行视频会议工具(Zoom、Google Meet和MS Teams)的桌面和移动版本的可访问性和可用性，供视障人士通过屏幕阅读器、键盘或手势进行交互。这包括两次检查评价，以测试桌面和移动设备版本的最重要功能，并对视力受损的用户进行两次调查，以获得关于所选视像会议工具的可及性的信息。65人回答了桌面平台的调查，94人回答了移动平台的调查。结果显示，Zoom比Google Meet和MS Teams更受欢迎，但这些工具都不能通过屏幕阅读器、键盘或手势完全访问。最后，本实证研究的结果被用来为视频会议工具和辅助技术的设计者制定一套指导方针。

期刊介绍： Computer and information technologies have re-designed the way modern society operates. Their widespread use poses both opportunities and challenges for people who experience various disabilities including age-related disabilities. That is, while there are new avenues to assist individuals with disabilities and provide tools and resources to alleviate the traditional barriers encountered by these individuals, in many cases the technology itself presents barriers to use. ACM Transactions on Accessible Computing (TACCESS) is a quarterly peer-reviewed journal that publishes refereed articles addressing issues of computing that seek to address barriers to access, either creating new solutions or providing for the more inclusive design of technology to provide access for individuals with diverse abilities. The journal provides a technical forum for disseminating innovative research that covers either applications of computing and information technologies to provide assistive systems or inclusive technologies for individuals with disabilities. Some examples are web accessibility for those with visual impairments and blindness as well as web search explorations for those with limited cognitive abilities, technologies to address stroke rehabilitation or dementia care, language support systems deaf signers or those with limited language abilities, and input systems for individuals with limited ability to control traditional mouse and keyboard systems. The journal is of particular interest to SIGACCESS members and delegates to its affiliated conference (i.e., ASSETS) as well as other international accessibility conferences. It serves as a forum for discussions and information exchange between researchers, clinicians, and educators; including rehabilitation personnel who administer assistive technologies; and policy makers concerned with equitable access to information technologies.
