On the creation of content:

On retrieving of content:

  • Matching/discoverability of relevant content, relevant consumability

Lessons from our tools:

  • Rich, multi-layered, accessible video player
    • Ease of operability by different input modes (mouse, keyboard)
    • Customizability of UI (UI size for operability, contrast and text size for perceivability)
    • Layering of content alternatives
      • Standard A/V track
      • Audio descriptions (audio narration of what's happening visually on the screen)
      • CC and transcript
    • Portability of content--video on standard platforms, but also other exports (i.e., downloadable/printable transcript)
    • Scannable video: break the linear nature of video (and help to consume at one's own pace)
      • Interactive transcript (and portable transcript)
      • Scrubber with frame preview and caption
  • Authoring environment
    • Gentle prodding of author to remind them to add content alternatives for every kind of non-text content added
    • Adjustable UI size, both in authoring and presentation
  • Universal Subtitles
    • Accessibility guidelines and lessons in authoring captions (both design of authoring environment & for content producers)
  • UIO
    • Adjusting presentation of content to be more easily perceivable to the learner (make learning possible)
    • Text adjustments: size, colour contrast (both strong and mild, the latter to cater to photosensitivity), style (some type is more readable than others, both generally speaking and also for specific individuals; cite dyslexia type), line spacing
    • Increased operability by making things more easily clickable by mouse (Fitts' law)
    • Condensing text/summarizing headers (Hick's law)
  • No labels
