  4. 4. Page 4http://tinyurl.com/annotation4a11y Visual Content is Challenging ●  Images tend to lack proper descriptions ●  Mathematics often rendered via images – MathML has poor adoption by web browsers and reading systems ●  Video description has even less support
  5. 5. Page 5http://tinyurl.com/annotation4a11y Current State Blind and vision impaired students often require support to access the knowledge provided by non-textual elements ●  Disability Support Services (DSS) offices in Higher Ed ●  Teachers and aides ●  Parents ●  Friends

  10. 10. Page 10http://tinyurl.com/annotation4a11y Requirements for Annotations ●  Accessible user experiences ●  Support for granular image annotation ●  Annotations in HTML and MathML markup ●  Mechanism to request annotations from sighted users ●  Metadata to identify the annotations as alternatives ●  Mechanism for original publishers to query, analyze and pull-in "crowdsourced" descriptions and transcriptions
  11. 11. Page 11http://tinyurl.com/annotation4a11y Conclusion ●  Annotation can be a powerful tool for addressing accessibility of non-textual content on the web and in eBooks ●  It’s happening today with disparate tools ●  We need a unified and standard mechanisms, so that the efforts of a few “Good Samaritans” can have broader impact gerardoc@benetech.org | @gcapiel
