ASR: Ari Screen Reader for Website Applications
AltmetricsView Usage Statistics
With the current technological advancements, an extraordinary amount of data is available over the Internet. 59% of the world population, which accounts to 4.57 billion people have access to the Internet and retrieve or generate a variety of data and information through it. Also, 15% of the world population has some forms of disability, and this comes with certain accessibility issues that restrict them from properly and fully make use of various websites. Most of the websites, accessed by the general public, are now developed so that a person with a disability can access and perform all the tasks using screen readers. However, they do not provide default screen readers alongside the web content. This thesis describes how a screen reader tool can be integrated with a website and help the users’ access the website’s information. In particular, the proposed Ari Screen Reader (ASR) helps users navigate web pages using a web browser without the use of external screen readers. Also, ASR enhances the user experience of both disabled and non-disabled users. This thesis includes an overview of web accessibility, a brief survey of related research and development efforts, a user study that helped motivate the work presented here, details of software specification and design, examples of ASR use, and a feature-based comparison with similar existing tools. Conclusions and pointers to several directions of future work are also provided.
