There are no comments regarding the rest of the existing sections under Navigation and Control . Provide inter-page navigation facilities. Such facilities may concern memory aids for blind people, non-linear history presentation, alternative presentation of bookmarks, enhanced feedback for visited pages or pages in the bookmarks, ageing of pages, etc. C. Orientation Preliminary ideas concerning the provision of orientation support to the user. Bellow are the main questions which appear in the current version of the guidelines document, followed by our corresponding proposals.
Size is a difficult issue, as different users perceive size in different ways.
Alternatively, the number of sentences in the document could be used. For blind, or visually-impaired users, an appropriate representation for approximate document size should be established. The browser would then use one of the three alternatives to characterise a document. A good solution for a brief overview of the contents of the page appears in the current version of the guidelines under the section Document Summary Information . An alternative type of content overview is also discussed in the same document, under the section Document Structural Information .
