      After successfully completing this module, you will be able to:
      create accessibility personas
      understand the challenges of users with disabilities
      apply design tips for different disability types

      Challenges users face
      Design tips
      Summary and Design Resource
    • 3. Hit or Myth
      Accessible sites look boring
      “Text-only” pages are a good way to provide accessibility
      (Myth)
      (Myth)
    • 4. Hit or Myth
      Accessible sites look boring
      “Text-only” pages are a good way to provide accessibility
      It’s possible to design a single version of web content that is accessible across all spectrum of disabilities
      (Myth)
      (Myth)
      (Myth)
      Universal Design
    • 5. Design Process
      When in a project do you think “accessibility?”
    • 6. User-Centred Design Process
      Evaluate
      User Research
      Design
      Development
      Scenarios and Requirements
    • 7. Personas:a description of a representative user(a pretend person who represents a type or a group of users)
    • 8. Create Personas for Your Design
      Ask yourself :
      Who are the users?
      What are the activities they wish to perform?
      Why they might visit your websites? i.e. motivation
      How does our website/services fit into their context of life?
    • 9. Create Accessibility Personas
      Background: picture, name, age, job, interests, …
      Attributes: ability, access points, technical expertise,..
      Goals:
      What are they trying to achieve?
      Why are they trying to achieve this?
    • 10. Persona Example: Robert(Retiree with aging related conditions)
      Background
      • age: 65
      • 11. occupation: retired
      • 12. aging related disabilities: low-vision, hand tremor, short-term memory loss
      • 13. Technical level: not tech savvy, only uses the web to manage some of his household services and finances
      Attributes
      • uses screen magnifier
      • 14. uses computers only at home
      • 15. preferred large links and icons
      • 16. finds scrolling stickers and flashing animations very distracting
      • 17. easy to get lost in the site
      “I often get stuck on a website.”
      Goals
      • able to use basic services on the web easily
      • 18. don’t get stuck on pages and able to save his data
      • 19. able to customize a website font and color
    • Tips for Creating Personas
      Empathy: focus on our target users and their pain points
      Concrete: include details of your personas and make them real
      Apply a face to your persona
      Include disability condition and AT information for accessibility personas

    • 22. The Four POUR Principles
      The Four POUR Principles
      WCAG 2.0 principles:
    • Vision Disability
    • Blindness
      Let’s experience it!
      What are the challenges?
    • 29. Blindness: Challenges
      • cannotscan for content
      • 30. primary interact with keyboard
      • 31. hard to access visual information
      • 32. limitations of screen readers
    • Blindness: Design Tips
      Perceivable: include detailed text description for graphics, video, animation
      Operable: fully operable with keyboard
      Understandable: make sure your page has a clear, and consistent structure, and avoid using complex tables
      Robust: be careful with new technologies that will raise incapability with AT
    • 33. Low-Vision
      Let’s Experience it!
      What are the challenges?
    • 34.

      • 42. cannot see pages with low contrast
    • Low-Vision: Design Tips
      Perceivable:
      To make text more legible when enlarged, use true text as much as possible, rather than text in graphics.
      To the extent possible, use percentages, rather than absolute units (e.g. pixels), in your document layout.
      To the extent possible, maximize the contrast of your web pages, including graphics, fonts, and backgrounds
