SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
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.
