>Didier says: . If we could simply get an aural model, Wow we >would have a great tool. I've spent lots of time doing conversions from SGML into synth speech, although the synthesiser is too simple to reflect all the options available for navigation - the main blocker to having a model. The research indicates that aural presentation is OK for linear usage, but when the user wants to 'skim' read a document, the navigation is the key element. How to identify aurally that this is a higher/lower level of heading than the last one, or some absolute level? Sonification, voice change are the favoured means, with user options selecting the preferred one. Basic elements of an audio model are toc (always needed) 'statement(s)' - this could be anything from a single sentence to a chapter, then it goes grey. No agreed way of presenting other views of a document. Other structural elements are only of use as per 'skimming' perspective. No agreed presentation method even for simple lists. No one has ever tackled tables in terms of research AFAIK. Only other variance is in-lines. how to indicate a link presence? How to indicate a visited link? How to indicate where a link goes to? emphasis? sonification again? producer notes (not part of text)? Diagram descriptions? TV Raman has the best system, on emacs, but he uses a $1000 synth, rather than the more common ones. > >regards DaveP DSSSList info and archive: http://www.mulberrytech.com/dsssl/dssslist
