Abstract

This chapter presents the structure of an index which serves as support so allowing the development team to create the specification of the context of use document for the development of Web applications, bearing in mind characteristics of usability and accessibility, each point of the index being explained in detail. A correct preparation of this document ensures the quality of the developed Web applications. The international rules and standards related to the identification of the context of use have been taken into account. Also, the functionality limitations (sensorial, physical, or cognitive) which affect access to the Web are described, as well as the technological environment used by disabled people (assistive technologies or alternative browsers) to facilitate their access to the Web content. Therefore, following the developed specification of the context of use, usable and accessible Web applications with their corresponding benefits can be created.
