What devices can I use to access PKB?

PKB works on any device with a modern browser and an internet connection. These include large screens such as library desktop computers and small screens such as smartphones. PKB works on all modern browsers (Chrome, Safari, Firefox, IE 11+).

For iOS devices, such as iPhones, we support any device that is on iOS 11 or above.

What languages is PKB available in?

PKB works in 22 languages. The software automatically detects the language of the web browser and defaults to that language. The user can also manually choose the language from the drop-down menu at the bottom of a page. To learn more about the languages available and how to change your language, please see our languages page.

How does PKB support users with limited vision?

As PKB works in a web browser it supports full zooming.

Colour blind people can use the pages because the colours are distinguishable in grayscale. Where colour gives meaning, PKB provides a non-colour signal of the same meaning. For example, in the symptoms page, the severity of a symptom is indicated by the colour and the height of the symptom severity bar. To test this out you can use the Colour blindness empathy test extension on Firefox

PKB's web page elements work with standard screen readers such as JAWS. The first link in the page allows skipping the navigation bar. Each element is audible in screen reader format. You can read the symptoms page below as it sounds in a screen reader.

The screenshot above shows simple testing by choosing "No style" from the View > Page style menu in Firefox. For comprehensive testing use the JAWSInspect Firefox extension.
