Accessibility stands as a quality requirement for Web applications. However, current accessibility automatic evaluation tools are not capable of evaluating DOM dynamic generated content that characterizes Ajax applications and RIAs -Rich Internet Applications. In this context, this paper describes an approach for testing accessibility requirements in RIA, by using acceptance tests. The authors had implemented a set of assistive technology user scenarios in the acceptance tests, in order to guarantee keyboard accessibility in web applications. As the scenarios were implemented as acceptance tests scenarios, they provide accessibility analysis over all layers of the software, from server-side to client-side implementations (JavaScript and dynamically generated DOM elements) in RIA. The test scenarios are automatically executed, and by doing so, fit the Continuous Integration process of constant delivery of new functionalities in Web projects.
In this paper we describe a web content adaptation tool for assisting low-literacy readers to access online information. The"Educational FACILITA" tool provides innovative features and the design of more intuitive interaction models. Especially, we propose an interaction model and web application that explore the Natural Language Processing tasks of lexical elaboration and named entity labeling for improving web accessibility.
The Web has become an extremely important source of information and services that have been made widely available. Navigation is an important aspect in designing a Web site in order to make the information easy to find, however the task of organizing and structuring information from a website can become complex as the set of information and services provided increases. The aim of this study is to investigate the effect of eight different types of menus while performing two tasks for each menu. The target for the experiment was of people aged over 40 and some experience in using the Internet. The experiment revealed that menus which presented properties more commonly found in web applications, the task completion time and number of errors was lower, during the sessions.
