Visual-impaired communities are one of the hindrances groups to accessing web content access in the world. The obstacles encountered by this community in their current practices and to develop best practice guidelines to overcome the digital divide in Sri Lanka become gap filling of this domain. A preliminary survey indicated five main problems including access limited by the impairment, usability issues due to lack of design, unavailability of visually impaired-friendly applications, lack of communication, and web navigation issues are the most dominant pertaining issues. To overcome those issues, solutions are tested and validated using the Design Science approach. Result Indicate that significant factors need to be incorporated, ensuring keyboard-friendly websites, easy accessibility and support with semantic annotation by adding alternative text for images. Furthermore, use headers to structure the content correctly, design all forms to support accessibility in mind including Content developing and designing, navigation, the best colour combination, Pre-recorded video with the audio facilities, braille support on the web, the designing option has no significant impact on visually impaired web users. Introducing a rating widget option to a website identifies the level of accessibility features availability facilitates, thereby overcoming the disability digital divide. The results further conclude that a significant difference exists in websites, with and without the involvement of the visually impaired community. Semantic web and semantic annotations of the context of page elements, content serialization, and navigation by special keyboard commands are also highly influencing the effective use of the web and increasing the satisfaction level in the website accessing process.

翻译：视障群体是全球范围内访问网络内容的主要障碍群体之一。该群体在现有实践中遇到的障碍以及为克服斯里兰卡数字鸿沟而制定最佳实践指南，填补了这一领域的研究空白。初步调查表明，五大主要问题包括：因残障导致的访问受限、设计缺陷引发的可用性问题、缺乏视障友好型应用程序、沟通障碍及网页导航困难。为解决这些问题，本研究采用设计科学方法对解决方案进行测试与验证。结果表明，需整合关键因素以确保网站支持键盘操作、提供便捷访问功能，并通过添加图像替代文本实现语义标注支持。此外，应正确使用标题组织内容结构，以可访问性为导向设计所有表单（包括内容开发与设计、导航、最佳色彩搭配、预录视频配合音频功能、网页盲文支持），而设计选项对视障网络用户无显著影响。在网站中引入评级组件功能可识别可访问性功能的可用层级，从而弥合残障数字鸿沟。研究进一步得出结论：有无视障群体参与的网站存在显著差异。语义网络与页面元素上下文的语义标注、内容序列化以及通过特殊键盘命令进行的导航，均对提升网络有效使用率及用户访问过程的满意度具有重要影响。
