Figure 1.WebNexter dynamically serves to screen-reader users a set of guided tours for each of the item collections present in the current web page.By accessing a guided tour, screen-reader users can navigate a collection linearly and bypass lists [9], thus accessing content faster. ABSTRACTRecent research has shown that screen-reader users can find information on a website almost twice as fast if they bypass indexes and just navigate the content pages of a collection linearly (in a guided-tour fashion). Yet manually building a guided tour for each existing index requires significant resources from web developers, especially for very large web applications.To address this problem, we introduce WebNexter, a web browser extension that automatically generates guided tours from the indexes present in the page a screen-reader user is currently visiting. WebNexter is manifest in a Google Chrome extension that implements screen-reader accessible, dynamic construction of guided tours from a very large, eCommerce website prototype. Our goal is to develop WebNexter extensions for multiple browsers that will work on any website; this will relieve developers from the burden of designing guided tours while greatly accelerating the screen-reader navigation experience during fact-finding.

Whereas glancing at a web page is crucial for navigation, screen readers force users to listen to content serially. This hampers efficient browsing of complex pages and maintains an accessibility divide between sighted and screen-reader users. To address this problem, we adopt a three-pronged strategy: (1) in a user study, we identified key page-level navigation problems that screen-reader users face while browsing a complex site; (2) through a crowd-sourcing system, we prioritized the most relevant sections of different page types necessary to support basic tasks;(3) we introduced DASX, a navigation approach that augments the ability of screen-reader users to "aurally glance" at a complex page by accessing at any time the most relevant page sections. In a preliminary evaluation, DASX markedly reduced the gap in page navigation efficiency between screen-reader and sighted users. Our contribution provides the groundwork for rethinking access strategies that strongly tie aural navigation to user's tasks.
