Jon Gunderson, Ph.D. Coordinator of Information Technology Accessibility Division of Disability Resources and Educational Services College of Applied health Sciences University of Illinois Phone: 217-244-5870 E-mail: jongund@illinois.edu AbstractThe Functional Accessibility Evaluator (FAE) 2.0 is designed to evaluate and summarize the accessibility of the pages in an entire website and AInspector Sidebar is a Firefox add-on to inspect and highlight accessibility problems and features on individual pages. Accessibility Bookmarklets provide a way to visualize hidden accessibility information to support accessible design and manual checking of web pages for accessibility features. All the tools are open source and they evaluate accessibility based HTML5 and ARIA 1.0 techniques and features for meeting the Level A and AA requirements of the W3C Web Content Accessibility Guideline (WCAG) 2.0. Open source tools can be freely used and customized for individual needs. More InformationFunctional Accessibility Evaluator 2.0The Functional Accessibility Evaluator (FAE) 2.0 is designed to evaluate the pages of an entire website. FAE 2.0 uses a server based browser emulator (e.g. HTMLUnit based utility) to generate the same DOM as a desktop browser and the run the OpenAjax Accessibility Evaluation Library on the DOM after “onload” scripting is completed. FAE 2.0 provides accessibility information on individual pages and summaries across all the pages. The summaries provide information on how an individual rule or groups of rules (e.g. WCAG Guideline or Rule Category). It is designed to allow developers and auditors estimate the accessibility of the pages in an entire website to verify implementation of accessibility features or identify areas of the website that need additional work. Functional Accessibility Evaluator 2.0 http://fae20.cita.illinois.edu/ AInspector Sidebar for FirefoxAInspector Sidebar is an add-on to the Firefox browser and allows the live DOM of Firefox to be evaluated for accessibility using the OpenAjax Accessibility Evaluation Library. This is very important in web applications and application frameworks like Angular.js that dynamically generate HTML content using Javascript. A top level sidebar view is a summary of rule results, the number of rules that resulted in a violation, warning, manual check or passed based organized by WCAG Guideline or Rule Category (e.g user preference). Selecting one of the groups (e.g. a specific WCAG Guideline or Rule Category) in the summary view changes the view to the list of rule results associated with the group. The group view list also can be used to identify the rules that did not apply to the current web page (e.g. a typical page only has 40-50 rules that apply to its content out of over 120 rules in a ruleset). Selecting a rule result shows the elements (e.g. target resources) in the page that were associated with the rule. Selecting element level results will highlight the element on the web page, and a button is also available to open the Firefox DOM Inspection tool with the element selected. The sidebar allows for delayed evaluation to allow users to change the state of content (e.g. opening a mega menu) before the evaluation takes place.

He is responsible for computer and information technology accessibility issues for students with disabilities at the University of Illinois. He is the past chair of the W3C User Agent Working Group and currently involved in making dynamic HTML more accessible as part of the W3C Protocols and Formats and W3C WCAG Techniques working groups. He is the primary software developer of the open source OpenAjax Accessibility Evaluation library and Functional Accessibility Evaluator 2.0 (FAE). He has taught numerous online courses and workshops on accessible web design including courses on using the new W3C Accessible Rich Internet Application (ARIA) specifications to create accessible web applications. He leads both regional and national consortiums of higher educational institutions to promote and collaborate on Information technology access issues to people with disabilities.
