Using Usablenet Assistive is simple and easy for users that want to access a conforming version of content and features. Users simply access the version via the link of the original page , typically added to the start of a non fully conforming page and enter a accessible version. The user then can continue using the site in their normal way, navigating and using features and functions.
Usablenet’s team have worked to ensure the accessible version has been developed to guarantee the easiest experiences for assistive users while maintaining the full functionality of the site.
This is achieved by Usablenet Assistive consuming the original web site, by applying rules the Usablenet Assistive team have written to improve accessibility, and by generating a new page that is compliant to the WCAG and other web accessibility standards.
The process is dynamic and never stores or caches any of the sites content or your user’s information. This is not a static text only site view that needs to be maintained but a dynamic, conforming accessible version of web site features and content.
Usablenet Assistive allows you to choose your display preference. These preferences are handled via cookies so that Usablenet Assistive can remember your choices. You must enable cookies in your browser.
Display preferences can be selected in a section entitled
Assistive Options located at the bottom of any
"dynamic conforming version" page.
Hold down ALT key and press T to jump to the Assistive Options section.
If you are using Internet Explorer, you must hold down ALT key, press T and then press enter key to obtain the same result.
If your browser has a menu with T as shortcut (for example 'Tools' in Internet Explorer) you can still open it using the keyboard by pressing ALT key and T separately.
The last part of Assistive Options section can be used to view the original version of the "dynamic conforming version" page, to launch Usablenet Assistive on any other public web page and to view the Usablenet Assistive Main Page.
Within the Assistive Options section you can select the following preferences.
- Font size: to be used when displaying the page content. This is useful for low vision persons or when you need to enlarge the content of a page (for example when projecting a page during a public presentation). Press the "larger" link to enlarge, "smaller" to reduce the size, or "default" to reset it to the default value.
- Color mode: to be used for background and foreground colors. In many cases you might prefer viewing the page content in black over a white background. But sometimes it is easier to read and scan the page if you use inverted colors. Available foreground/background combinations enhance the contrast and are: black on white, yellow on black, black on cream. Feel free to try them all and select the one that looks the best.
- Textual links: to people with motor disabilities (or those using less than optimal pointing devices) moving a pointer on a small link to select it is a complex task, requiring lot of attention and often leading to errors. If you use this option, Usablenet Assistive frames each textual link into a rectangular box and it makes sure that these links stand out clearly from the nearby elements.
- Moving navigation bars to the bottom of the page:
the webmaster can configure Usablenet Assistive to move some objects of the page
(for example the main navigation bar, the search box) to the bottom of
the page. In this way those objects, that usually are repeated all
over the website, are not in the way if you use screen
readers. You get directly to the main content of the page first, and
can still get to these elements by scrolling the page.
However, you can set a preference of Usablenet Assistive to avoid this. Simply set the preference called
Move navbars to the bottom of the page(or
Do not move navbarsto unset it).
- Speedbumps: when deployed, Usablenet Assistive is limited to
registered web servers, in the sense that it will process only pages
hosted on web servers that are properly registered. The set of
registered web servers and their pages is called "dynamic conforming version"
realm and it is defined by the webmaster of the website. When you
activate a link that crosses the border of the "dynamic conforming version " realm (i.e. a
link that brings you outside the web servers registered within Usablenet Assistive)
by default Usablenet Assistive will alert you that you are leaving the "dynamic conforming version"
realm and will let you switch to
However, you can set the preference called
[Don't] alert me when leaving dynamic conforming versionso that Usablenet Assistive does not bother you with this alert page. In such a case Usablenet Assistive will switch off (i.e. the linked page will be displayed in original mode by your browser).
If you don't see this preference, it means that the webmaster has not configured Usablenet Assistive to exploit this feature.
- Not handled documents: when you activate a link
that does not refer to a web page, Usablenet Assistive will alert you that it can not
process that page and will propose to download the original file.
You can disable this alert page by setting the preference called
Open not handled documents directly. Set
Show a splash page for not handled documentsto re-enable the alert page.
Usablenet Assistive is fully PCI and HIPAA compliant and never stores or caches any of the sites content or your user’s information.

Usablenet Assistive works as a web proxy, and when it transforms a page it has to transform all the links and form buttons that are contained in the page. Each URL is transformed (remapping of URLs) so that the request is first filtered by Usablenet Assistive and then it is Usablenet Assistive that issues another request to the original web server. This process ensures that all changes made to the original site are instantly reflected in the accessible version.
Usablenet Assistive properly processes secure pages (i.e. it remaps secure pages into secure "dynamic conforming version" pages) only if the webserver uses public certificates. If the webserver requires HTTPS to access a page, but the webserver does not have public certificates, Usablenet Assistive would not process the page.
In this way Usablenet Assistive behaves as a very conservative browser, refusing to continue a transaction when it is insecure but the Usablenet Assistive user expects it to be carried out securely.
