Accessible Educational Web Media | AHG 2012 | Kathy Wahlbin & Suzanne Taylor21 Guideline 31: Complete Narration or Audio Description Explain Confusing Sounds Only need to describe visual elements necessary to understand But what if a Lion keep growling while the speaker speaks over it? Pretty confusing! Try to work the information in in a natural way, "Professor Smith of the Smith Zoo speaks to a small crowd at the zoo's lion exhibit."

29
Accessible Educational Web Media | AHG 2012 | Kathy Wahlbin & Suzanne Taylor29 Guideline 39: User Content When end users (e.g. students, instructors) can upload or create content, allow and facilitate alternatives for non- text content (e.g. alt-text for images, captions and audio descriptions for video, transcripts for audio) and, where significant text editing is possible, semantic markup (e.g. headings, data tables and lists).

31
Accessible Educational Web Media | AHG 2012 | Kathy Wahlbin & Suzanne Taylor31 Guideline 26: Contrast for Text Readability Using a contrast ratio tool, choose text color and text background color so that the contrast ratio between the colors is at least: 4.5:1 for small text 3:1 for text that is at least 18 points or bold 14 points 7:1 when one of the colors is red (or nearly red) and other color is black (or nearly black)

50
Accessible Educational Web Media | AHG 2012 | Kathy Wahlbin & Suzanne Taylor50 Staying on Task 1. Write text alternatives that serve the same purpose as the image, do not just label the image. 2. Do not use alt-text to provide new information that is not in the image. 3. Do not write text alternatives for images that are merely decorative. (See Pearson Guideline 38) 4. Do not provide more than brief labels for images that only repeat information that is already present in the text.
51
Accessible Educational Web Media | AHG 2012 | Kathy Wahlbin & Suzanne Taylor51 Tips for Writing Good Alternative Text for Complex Images Effective Descriptions 1. Understand the context. 2. Keep it concise. 3. Start general and move to specifics. 4. Use polished and grammatically correct language. 5. If the image is of a particularly obvious or unique type, consider identifying the type of image (e.g. cartoon, photo). 6. Pay Attention to New Items vs. Items Already Mentioned (i.e. a triangle vs. the triangle). 7. Check your work, by imagining your text in use. Does it serve the same purpose as the image? 8. Especially when describing how something looks, consider asking others to read your description to see if they agree with any poetic interpretations. 9. Does the image suggest any of the structures available in structured text ? Use headings, bulleted lists, numbered lists, definition lists, nested lists and tables to organize long or complex text alternatives. 10. Double check that the data in the text alternative is the same as the data in the original image. 11. Always use the same terminology and reading level that is used in the main text.
