“…This is the basis of the use of the travel metaphor [3] in increasing Web accessibility. Here, the travel objects that facilitate movement through a Web page are identified and semantically marked up [22]. This markup is then used to help transcode a page into either an order that facilitates use or a fragmentation that facilitates use.…”

“…Harper et al [3] and Yesilada et al [22] have used the metaphor of travel to raise the notion of using a Web page above that of dealing with mere 'sensory translation'. Just as people use travel objects in the environment (signs, landmarks and other cues) to help them orientate and navigate, so a Web user can use travel objects on a Web page to aid mobility-the ease of travel in a Web page.…”

It is well known that many Web pages are difficult to use by both visually disabled people and those who use small screen devices. In both cases there exists a problem of viewing a great deal of information with presentation capabilities reduced from the intended formatted large-screen colour display. It is pertinent, however, to ask how the presentation of Web pages on a standard display makes them easier for sighted people to use. To begin to answer this question, we report on an exploratory eye-tracking study that investigates how sighted readers use the presentation of the BBC News Web page to search for a link. We compare the standard page presentation with a "text-only" version and observe both qualitatively and quantitatively that the removal of the intended presentation alters "reading" behaviours. The demonstration that the presentation of information assists task completion suggests that it should be re-introduced to non-visual presentations if the Web is to become more accessible. Finally, we propose that models derived from studies that reveal how presentation is used to aid task completion can form the basis for annotation and transcoding of Web pages to present pages in a more usable non-visual form.

Most Web pages are designed for visual interaction so the mobility, or ease of travel, of visually impaired Web travellers is reduced [2]. Objects that support travel and mobility are not in an appropriate form for nonvisual interaction. Our goal is to enhance the mobility of visually impaired Web travellers by annotating pages with a travel ontology that aims to encapsulate rich structural and navigational knowledge. We propose a semi-automated tool 'Dante' which aims to analyse Web pages to extract travel objects, discover their roles, annotate them with a travel ontology and transform pages based on the annotations to enhance the provided mobility support. This poster introduces the travel ontology and presents how Web pages are annotated with this ontology to guide the transformations.

Currently, the vast majority of web sites do not support accessibility for visually impaired users. Usually, these users have to rely on screen readers: applications that sequentially read the content of a web page in audio. Unfortunately, screen readers are not able to detect the meaning of the different page objects, and thus the implicit semantic knowledge conveyed in the presentation of the page is lost. One approach described in literature to tackle this problem, is the Dante approach, which allows semantic annotation of web pages to provide screen readers with extra (semantic) knowledge to better facilitate the audio presentation of a web page. Until now, such annotations were done manually, and failed for dynamic pages. In this paper, we combine the Dante approach with a web design method, WSDM, to fully automate the generation of the semantic annotation for visually impaired users. To do so, the semantic knowledge gathered during the design process is exploited, and the annotations are generated as a by-product of the design process, requiring no extra effort from the designer.
