Middleware to expand context and preview in hypertext

Published: 01 September 2003 Publication History

Abstract

Movement, or mobility, is key to the accessibility, design, and usability of many hypermedia resources (websites); and key to good mobility is context and preview by probing. This is especially the case for visually impaired users when a hypertext anchor is inaccurately described or is described out of context. This means confusion and disorientation. Mobility is similarly reduced when the link target of the anchor has no relationship to the expected information present on the hypertext node (web-page). We suggest that confident movement with purpose, ease, and accuracy can only be achieved when complete contextual information and an accurate description of the proposed destination (preview) are available. Our past work (1) deriving mobility heuristics from mobility models, (2) transforming web-pages based on these heuristics, and(3) building tools to analyse and access these transformed pages; has shown us that a tool to expand context and preview would be useful. In this paper we describe the development of such a middleware tool to automatically and dynamically annotate web-pages with additional context information present within the page, and preview information present within hypertext link destinations found on the page.
