Initially, text-based terminals were used as computers with DOS OS. The terminal had a cursor, and text was typed into the terminal. Accessibility for users was provided by using the text and events related to the user. The accessibility formats were voice and text in various font levels. The web has evolved, and accessibility support for the web is very important. HTML5 helps us to design websites for PDAs, Mobile, TV browsers, and other devices. Web browsers use the accessibility API for disabled users. Accessibility APIs used in the browsers are MSAA, UIA, and Microsoft UIA. This chapter in the book talks about accessibility software and hardware used in software design and development.

Keywords: Accessibility, Design, Hardware, Platform, Software.
