  1. Fundamentals of Graphic Communication 3.5 Accessible Design

  2. Overview • What is accessibility? • Why is it important? • Design guidelines • Types of disabilities • Accessibility testing

  3. What is accessibility? • Accessibility is the degree to which technology is usable by people with disabilities • Universal access is the philosophy of designing technology and information to be usable by all people without specialized adaptations

  4. Accessible technology • Assistive hardware • Allow disabled users to interact with the computer • Examples • Specialized keyboards • Head trackers • Braille terminals Matias Corporation

  5. Accessible technology • Accessibility software • Designed to provide an accessible interface between other software and the user • Examples • Voice recognition • Speech synthesis • Screen readers • Mouse / keyboard helpers • We want software to be accessible; that is, to work transparently with accessible technology without sacrificing quality

  6. Why’s it important? • There are millions of disabled people in the US • Non-accessible products limit your audience • It’s the law • Section 508 requires government-funded websites to meet accessibility guidelines • It’s a nice thing to do • Share your creations with the world • Accessible design often results in good design • Easy-to-use products benefit everyone

  7. Good Grips • Accessible design requires making products easier to use for everyone • Who doesn’t like that? Good Grips

  8. Fred and Ginger • Accessible technology often requires creative technical solutions • Mainstream products may benefit from these solutions DEKA

  9. Design principles (Web Content Accessibility Guidelines 2.0) • Perceivable Ensure that all content can be presented in form(s) that can be perceived by any user - except those aspects of the content that cannot be expressed in words. • Operable Ensure that the interface elements in the content are operable by any user. • Orientation/Navigation Facilitate content orientation and navigation • Comprehendible Make it as easy as possible to understand the content and controls. • Technology Robust Use Web technologies that maximize the ability of the content to work with current and future accessibility technologies and user agents.

  10. More principles • Present information in a clear and straightforward manner • Limit large amounts of text • Structure documents clearly • Express ideas in multiple media when possible • ALT text for HTML images • Transcripts for audio/video content • You don’t need to sacrifice visual style for accessibility

  11. Types of disabilities • Visual • Blindness • Low vision • Color blindness • Hearing • Motor skills • Cognitive disability • Reading disorders • Attention disorders • Memory impairments

  12. Blindness • User cannot see visual content • Pictures, diagrams, animations, etc. • May use a screen reader to get information • Cannot scan a page quickly • Must navigate linearly through text • Solutions • Provide structure to text for easy navigation • Add text or audio descriptions to images/video • Follow standards for maximum compatibility with screen readers

  13. Low vision • Many types • Poor vision quality • Partially occluded vision • Very common in seniors • Low-contrast text difficult to read • Solutions • Allow font resizing • Allow color schemes to be changed • Add text or audio descriptions to images/video

  14. Low vision • Many types • Poor vision quality • Partially occluded vision • Very common in seniors • Low-contrast text difficult to read • Solutions • Allow font resizing • Allow color schemes to be changed • Add text or audio descriptions to images/video

  15. Color blindness • Inability to distinguish between certain colors • Affects 10% of males • Often have problems with red and green • Solutions • Allow color schemes to be changed • Don’t differentiate on hue alone • Saturation • Value • Shape

  16. Color blindness What you see What color-blind users see visibone.com

  17. Is this accessible? Big Fish Games

  18. Better PopCap Games

  19. Hearing impairment • User cannot hear audio content • This one is easy to test for • Turn off your speakers! • Solution • Provide captioning for all audio content

  20. Impaired motor skills • Difficulty using mouse and keyboard • Inaccuracy while clicking • Slow input • May use specialized input device • Solution • Do not require precise clicking • Allow alternate input methods • Keyboard • Mouse • Voice

  21. Color blindness tools • Will send these out later
