StandardsWCAG 2.0
★ Four principles of Accessibility:
★ Perceivable
★ Operable
★ Understandable
★ Robust
★ www.w3.org/TR/WCAG20/
„Understanding Accessibility can drive you nuts,
right?“
Do you have an idea why?
It‘s not about machines, it‘s
just about people ...
... with disabilities?!
No! It‘s about diversity of
human beings!
They have different strenghts of
perception and prefered actions!
In general we tend to see only
handicaps.
It‘s a matter of perspective
Imagine, you can see but you are
still blind...
... because you don‘t know
enough about these people!
Try to imagine their perception and actions ...
... like a film director
switching to the role of the
actors!
Do the same as a designer or developer
diving into different user experiences!
UserExpierences I
★ Visual Asthetics and Layout
★ Colors, Contrast and Fonts
★ Information Architecture/Contextual Content
★ Structure and Semantics
★ Functions und Interactions
★ Devices
★ Alternative Content Support
UserExperience II (Examples of specialists)
★ Visual Asthetics and Layout (Deaf People)
★ Colors, Contrast and Fonts (Visually Impaired/Deaf)

★ Structure and Semantics (Blind)
★ Functions und Interactions (Motion Impaired/Blind)
★ Devices (Blind/Visually Impaired/Motion Impaired)
★ Alternative Content (Blind and Deaf)
UserExpierences III (Examples)
★ Visual Asthetics and Layout (Design)

Accessibility is a balance of a satisfying
and holisticuser experience!
Never try to conceive of WCAG 2.0 as a checklist. Every
Website has its own context.
Drupal AspectsAccessibility - sensitive Drupal
★ Flexibility of content building(Node Architecture/Regions)
★ Clean seperation of Structure, Data and Design
★ Backend Theme can be easily designed and adapted
★ Modular Theme-Developing (Page.tpl, Node.tpl, Blocks.tpl etc.)
Drupal Aspects IIAccessibility - sensitive Drupal
★ Devel-Module, a great inspiration:
★ Debugging-Tool for Accessibility (WAI-ARIA, Alt-Text for Pictures)
★ Visualisation tool of semantical Structure directly on screen (visualize the invisible!)
Drupal Aspects IIIAccessibility case-sensitive
★ Accessibility features should be a standard in Drupal (Alt-Text for pictures etc./captions for videos) as assistant (without any need of modules)
★ Icons for backend navigation (would help with finding and understand)
