Internet Explorer and Windows

A number of tools can be used in the Windows environment when conducting accessibility testing. Some integrate with Internet Explorer, while others are stand-alone tools.

ACTF - aDesigner

ADesigner is available from the Eclipse Foundation; it is "an Eclipse RCP application." It is free and opensource. "Web developers can use aDesigner to test the accessibility and usability of Web pages for low-vision and blind people."


This tool, from the Paciello Group, is integrated into the Web Accessibility Toolbar, but it may be used separately, as a desktop application, if preferred. "The Accessibility Viewer (aViewer) is an inspection tool for Windows that displays the accessibility API information (MSAA, IAccessible2, UI Automation, ARIA, HTML DOM) exposed by web browsers to the operating system, and thus to any assistive technology (AT) such as screenreaders."
When getting started with aViewer, Steve Faulkner's AViewer Presentation and his AViewer video will be helpful.

Web Accessibility Toolbar (WAT)

The most current version of the "WAT" can be downloaded from Github by going to: Note that documentation, including keyboard shortcuts, is also posted there.

You may also find helpful information by visiting Microsoft's Accessibility Developer Hub. Here, you will find videos and documentation that cover topics such as making SharePoint and Office documents accessible, assuring accessibility on the Web, and creating Windows applications that implement accessibility APIs.

SSB Bart Group's YouTube video about the Microsoft Object Inspector provides a useful overview of how this tool can be used when testing Windows software or Web-based applications.
