Live. Learn. Access Intro to Accessibility
What is accessibility? Why is important? How designers should approach it?
What is accessibility?
Accessibility refers to the “ability to access” to any product, device, service, or environment by everyone
Universal Design aka Inclusive Design Refers to designing a product that’s usable by everyone.
Here’s an open secret… Everyone benefits when things are designed accessibly.
The Persona Spectrum
Permanent Temporary Wheelchair Leg injury Situational Travelling
But what happens online?
EXCUSE “People with disabilities don’t really use the web”
253 7.6 M Live with vision impairment BILLION 15% World Population 3.8 ? Live with some form of disability 36 M Are blind 275 M BILLION Are deaf or Hard of Hearing Global Internet Usage (~40%) Stats: World Health Organisation Report
Our audience is often more diverse than we imagine.
Web Accessibility means creating digital products that are available to as many people as possible everyone.
Empathy enable us to design more kindly.

Animations are fun, but not for everyone
