SlideWiki aims to make its website as accessible and usable as possible.
What does this mean?
This means that texts, images, forms and navigation should be accessible and understandable by as many people as possible. All users of the SlideWiki platform, with or without disabilities, should be offered the best possible browsing experience.
To achieve this, the website has been optimised to meet the W3C Web Content Accessibility Guidelines (WCAG) 2.0 Level AA (ISO/IEC 40500:2012)and European standard EN 301 549 V1.1.2.
Examples of items checked for accessibility include:
- Images and icons used on the platform to ensure they have the correct type of alternative text (alt tags), which can help screen readers users understand the content of pictures and diagrams.
- Keyboard only interaction has been provided for those who do not use a mouse or have alternative input/output systems such as screen reading, switch and/or braille access.
- Colour contrast levels and text styles have been optimised for readability.
- Use of ARIA landmarks to aid navigation and skip content.
Some screen reader users may encounter problems when navigating through items within slides in the presentation view. This is due to limited compatibility between screen readers and the technologies used to provide all users with keyboard control in a presentation mode.
Screen reader users should note the following keyboard shortcuts are available in presentation mode. Left arrow key or spacebar will move to the next slide. When a new slide is loaded, the content will automatically be read aloud. Right arrow key will return to the previous slide.
A basic presentation mode is available if the presentation mode URL is changed from /presentation to /presentationIE . This can allow a screen reader user to move around the slide content using the tab key. It is possible to test this experience by loading the Help guide in the basic presentation mode.
Technologies used in the SlideWiki Platform
The platform relies on the following technologies: HTML5, CSS, react-js and uses WAI-ARIA to support accessibility.
It is compatible with a range of browsers: Chrome, Firefox and Edge. However compatibility with Internet Explorer 11 or earlier is limited and we recommend using an alternative browser.
These browsers have been tested with the following assistive technologies: Jaws 18, NVDA 2018, VoiceOver on Mac and iOS and TalkBack on Android screen readers as well as a range of input/output devices that emulate keyboard navigation.
Presentation mode relies on role=application in order to provide shortcut keys. Technical notes about the problems with using this mode with a screen reader are available at SlideWiki development issue tracker.
If you have any problems with the accessibility of the platform, please contact us.
