Audio presentation of auto-suggest lists

One of the most significant advances behind World Wide Web (Web) 2.0 is the ability to allow parts of a Web page to be updated independently. This can provide an exciting, interactive experience for sighted users, who are used to dealing with complex visual information. For visually impaired users, however, these pages may be confusing: updates are sometimes not recognised by screen readers, while in other cases they may interrupt the user inappropriately. The SASWAT project aims to develop a model of how sighted users interact with dynamic updates, and use this to identify the most effective ways of presenting updates through an audio information stream. Here, we describe a ‘thin slice’ through this project, focusing on one form of update — the auto-suggest list.
