Home pages can be relatively empty with a simple mission statement or logo or consist of a list of links to other pages in the site. For a largish organisation we expect to follow several links to the page where the information lies. Sites often have the structure of a hierarchical tree. Authors frequently attach the meta keywords for a whole site to the home page resulting in the search for a particular item of information within the site returning the home page. The user must then move from the home page, through other pages, to the actual page containing the information.
Sighted users scan pages visually for information.
This is a complex cognitive activity but we know that it involves picking out individual parts of the page. Sighted users look at images for clues and then the headings and links to form a concept of the information on the page before engaging with the text. On pages with a lot of dense text they scan it by picking out relevant words and sentences. BrookesTalk support for conceptualisation of the Web Blind and visually impaired users also require the models described in Section 2. in order to search the Web. The aim in incorporating extra scanning functions in BrookesTalk is to support them in developing these models.
