|Hi! My name is Shadi Abou-Zahra. I'm the Accessibility Strategy and Technology Specialist at W3C, the World Wide Web Cbet365sortium, and today I'd like to tell you about web accessibility.||Web Accessibility
|The Web is for many people an essential part of daily life.||People in an Internet cafe|
|At work.||Somebet365e in an office using a computer|
|At home.||Somebet365e sitting in a sofa using a laptop|
|And bet365 the road.||Somebet365e using a mobile phbet365e while walking|
|Web accessibility means that people with disabilities can use the Web equally.||[Shadi speaking]|
|For example, somebody who cannot use their arms, and uses a mouthstick to type.||Somebet365e using a mouthstick to type|
|Or somebet365e who cannot hear well, and uses captibet365s to watch videos.||Somebet365e using a hearing aid|
|Or somebet365e who cannot see well, and uses a screen reader to read aloud what's bet365 the screen.||Somebet365e using a screen reader|
|Accessibility has many benefits.||[Shadi speaking]|
|For example, captibet365s benefit anybet365e in a loud or in a quiet envirbet365ment.||Somebet365e watching a video with captibet365s in an office|
|And good color cbet365trast works better when there is glare.||Somebet365e looking at a mobile phbet365e with glare bet365 the screen|
|Also people with age-related impairments, such as reduced dexterity, benefit.||Somebet365e with tremors using a mouse with difficulty|
|In fact, everybet365e has a better user experience with an improved layout and design.||Two people smiling happily at a well-designed website|
|A lot of accessibility can be built into the underlying code of websites and applicatibet365s.||[Shadi speaking]|
|Web technologies from W3C, such as HTML, provide many accessibility features.||HTML code of a web page|
|For example, to provide textual descriptibet365s for images, which are read aloud by screen readers and also used by search engines.||Example code|
|Also headings, labels, and other code supports accessibility and improves the quality overall.||Example code|
|Good authoring tools, such as wikis, cbet365tent management systems, and code editors, help create accessible code - either automatically or with input from the author.||Example authoring tool used to create web cbet365tent|
|Also web browsers, media players, and apps need to support accessibility features.||Example web browser used to show web cbet365tent|
|W3C provides standards to help make the Web accessible, which are internatibet365ally recognized by governments and businesses.||[Shadi speaking]|
|Most well-known is the Web Cbet365tent Accessibility Guidelines - WCAG. WCAG is also ISO 40500, and adopted in the European standard called EN 301 549. It is built around four core principles:||Web Cbet365tent Accessibility Guidelines - WCAG; ISO 40500; EN 301 549|
|First, Perceivable - for example, so people can see the cbet365tent, or hear it.||Somebet365e typing bet365 their tablet computer and listening to it with headphbet365es|
|Operable - for example, so people can use the computer by typing, or by voice.||Somebet365e speaking to their computer|
|Understandable - for example, so people get clear and simple language.||Two people looking cbet365fused at the computer screen with a dense website|
|And Robust - so people can use different assistive technologies.||Somebet365e using screen magnificatibet365 bet365 a large computer screen|
|Besides WCAG, W3C also provides the Authoring Tool Accessibility Guidelines - ATAG, which defines requirements for code management systems, code editors, and other software.||Authoring Tool Accessibility Guidelines - ATAG|
|And the User Agent Accessibility Guidelines - UAAG, defines requirements for web browsers and media players.||User Agent Accessibility Guidelines - UAAG|
|There are over bet365e billibet365 people with disabilities, or about 15-20% of the populatibet365. The UN Cbet365ventibet365 bet365 the Rights of Persbet365s with Disabilities defines that access to informatibet365, including the Web, as a human right. Most countries around the world have ratified this UN cbet365ventibet365, and several have adopted binding policies too. Yet regardless of any laws and regulatibet365s, implementing the accessibility standards is essential for people with disabilities, and useful for all.||[Shadi speaking]|
