1. Using Usablenet Assistive

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.


2. Setting your preferences

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.


3. Privacy aspects

Usablenet Assistive is fully PCI and HIPAA compliant and never stores or caches any of the sites content or your user’s information.

Please contact us at tt.support@usablenet.com for additional information.


4. Security aspects

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.
