This book addresses to some of the important issues, challenges and approaches related to web accessibility in context of visually impaired users. Speech is a convenient medium of interaction for visually challenged users, Internet accessibility for them is made possible by providing an alternative speech-based interface for human-computer interaction. Problems associated with speech based web interfaces are manifold. Most of the web content available today has been designed for the visual interface via graphical browsers. Screen Readers have been the primary tool for using internet by visually impaired. Unfortunately, most of the popular and workable screen readers are proprietary and bear a heavy price tag. Thus, Design and development of powerful yet affordable speech based interfaces would be certainly helpful in enhancing the overall Quality of Life of visually challenged.

Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)
This research aims to improve accessibility and usability of web applications for visually challenged users by providing alternative speech-based interfaces for human-computer interaction. The research focuses on designing, developing, and evaluating an enhanced speech-based web browser, identifying and addressing general issues related to web accessibility, and proposing frameworks for improving usability and performance of existing assistive technologies.
- Enhanced speech-based web browsing for visually challenged users.
- Addressing web accessibility issues for visually challenged users, particularly with regard to public utility websites.
- Developing a VoiceXML/VOIP-based client interface for interactive browsing of web applications.
- Proposing a hierarchical model for performance evaluation of assistive technologies for visually challenged users.
Zusammenfassung der Kapitel (Chapter Summaries)
- Chapter 1: Introduction introduces the research problem, objectives, scope, and proposed solution.
- Chapter 2: Background Work explores issues related to accessibility, usability, and navigability, discusses keyboard-based accessibility, and examines existing assistive technologies and their limitations.
- Chapter 3: WACTA, The Speech Based Web Browser describes the design, development, and evaluation of an enhanced speech-based web browser called WACTA for visually challenged users. It highlights key features and functionalities.
- Chapter 4: Direct Speech-Enabling Public Utility Websites addresses the need for direct speech-enabled functionalities on public utility websites. It proposes a framework that enables website owners to speech-enable specific functionalities at a minimal cost and effort.
