ACCESSIBILITY AS A NON-TECHNICAL FACTOR
• Accessibility is AWARENESS
• Accessibility is the result of a collaborative effort of all
the people involved in the design and implementation of
web contents
• It is about having a better understanding of the human
cognition and perception
• It is about translating this knowledge into technical
assets consumable by everyone

ACCESSIBILITY AS A TECHNICAL FACTOR
From the technical standpoint, accessibility is:
• guiding principle
• design techniques
• architectural style
• assistive technologies

WEB CONTENT ACCESSIBILITY GUIDELINES 2.0 (WCAG)
• Set of 21 guidelines distilled by W3C from practical
experiences
• Based on principles and NOT on technology
• Not an all-inclusive list of issues facing web users with
disabilities
• Internationally recognized and adopted standards
![Page 10: Rethinking Web Services Accessibility as a main factor 12 December 2013 Claudio Morgia, IT Chief, UNECE](https://reader031.vdocuments.mx/reader031/viewer/2022032414/56649ef35503460f94c061e5/html5/thumbnails/10.jpg)
WCAG 2.0 PRINCIPLES
1. Perceivable
– Text alternatives, captions, different renderings and
assistive technologies
2. Operable
– Keyboard based, longer times, improved navigation
3. Understandable
– Readable text, predictable content
4. Robust, maximize future compatibility

WCAG 2.0 LEVELS
• Organized into three levels of conformance
– Level A – the most basic web accessibility features
– Level AA – deals with the biggest and most common
barriers for disabled users
– Level AAA – the highest level of web accessibility, that
many websites cannot reach

ACCESSIBILITY AS A TECHNICAL FACTOR
TOOLS ARE VALUABLE, BUT NO REPLACEMENT FOR KNOWLEDGEABLE
PRACTITIONER

PRACTICAL ACCESSIBILITY
• Accessibility is not just a technical test before the web site delivery
• Accessibility is a principle since the beginning
• Experience disabilities as a driving force
• Include potential users
• It’s not different than the “plain old way” of designing user experience
• LISTEN TO YOUR USERS
