Ok, I have done a bit of work hear. There has been a few emails on guideline 3, both at the last FTF and by reviewing how other standard have handled it. I have tried to put it all together for tonight's call. Will try and make it, but no promises. I tend to fall asleep weighting for the call. Guideline 3 - Comprehension. Make it as easy as possible to use and understand Checkpoint 3.1 Use consistent presentation. I would add use a simple clear and consistent presentation I would add a checkpoint hear that you should keep to conventions (e.g.: links are underlined and blue) it seems the right place for it Use simple screen layouts or one thing at a time presentation. Checkpoint 3.2 Emphasize structure through presentation, positioning, and labels. I would add - (taken from Telecommunications Problems and Design Strategies for People with Cognitive Disabilities: Annotated Bibliography and Research Recommendations by Ellen Francik, Ph.D.) Structure text for easy scanning; provide headings. Use sequential numbers for numbered menus or lists. provide a page map were Checkpoint 3.3 Write as clearly and simply as is appropriate for the content. Avoid functions that require simultaneous actions to activate or operate. Use a two-step "select and confirm" to reduce accidental selections, especially for critical functions. Structure tasks, cue sequences, and provide step-by-step instructions. Provide definite feedback cues: visual, audio, and/or tactile. Provide concrete rather than abstract indicators. Use absolute reference controls rather than relative ones. Use goal/action structure for menu prompts. Support "wizards" which offer help, simplify configuration, and assist with sequences. Automate complex sequences like system backup, application launch, and user registration. Highlight key information. "use goal/action structure for menu prompts," Use highly descriptive words as hypertext anchors. Avoid the "click here" s yndrome. provide a mode with minimum functionality. - Eliminate or hide what isn't essential. Provide defaults and make it easy to re-establish them. Provide calculation assistance, or reduce the need to calculate.Success criteria avoiding metaphorical language which may be understood literally by people with autism. If you do use metaphor or irony or another style which may be misunderstood, consider adding an explanatory note. Use prompts for procedures and support decision making. work done at the FTF on this one: . Headings should be unique, and meaningful on their own. 2. first sentence must match the (single) idea expressed in a paragraph. 6. 1: and 2: are related to the requirement that links should make sense on their own. 20. One idea per paragraph: Test: replace each paragraph with a one idea sentence. (the first sentence, or a rewrite of that) Does the document make sense still? 17. Success Criteria: It is possible to map the document to pieces that are in the summary (exec summary, or heading outline, or ...) 3. success criterion: non-literal text is identified and a literal translation is identified 4. technique for 3: Use of Ruby. <p> The Prime minister is wanting to <ruby> <rb>have his cake and eat it too</rb> <!-- the metaphorical expression --> <rt class="http://wordnet.org/literally">get the benefit of seeming inflexible now, but be able to change his mind again later</rt> <!-- the rt element can be rendered alongside, or instead of, the rb content, according to the styling --> </ruby> in this instance.</p> 5. Jargon that is expected should be linked to a glossary / explanation 21. Use the jargon. This has to be linked to (depends on) 5: and should be linked to 4: 7. Linking to a glossary is not as cool as providing the information in a ruby so it can be shown/hidden fast. 22. Technique: Use Ruby 23. Technique: Use a rel="glossary" link. 8. Instructions should be step by step, and include visual references. 9. It should be possible to choose the detailed or the shortened instructions - LS 14. Use markup to identify flow of instructions 10. It should be possible to identify a graphic representation of an instruction. i.e. you can draw the picture. 11. CMN thinks that 10: is also useful for being able to translate to sign language. 12. Use active rather than passive expressions - this doesn't have massive support. 13. Use short sentences 15. Use short words in common vocabulary. 16. Success criterion: Substituting common words for uncommon words (without significantly expanding the size) does not change the meaning. Note that this requires a dictionary that marks the "difficulty" of a word. 18. Short sentences success criteria proposal: sentences contain no more than one relative clause 19. Grammar-based success criteria are language dependent 24. the Open University has done a lot of work on this. 23. Provide for consistent formatting that doesn't put people off. Checkpoint 3.5 Annotate complex, abbreviated, or unfamiliar information with summaries and definitions. At the ftf we discussed that jargon can be helpful and that you should use jargon when it exists, but that you should provide a translation. I would add that I do not think it ok to restrict translations of jargon and annotations of abbreviations to the fist occurrence. I can not remember annotations that I have used since high school, and am still dependent on the spell checker for ect/etc ....(etc....) 1, pictorial representation should be provided of each instruction, (if you can not do it in one picture, it is time to split up the instructions) 2, diagrammatic representation should be provided for relationships and flow of ideas. Supply a page map/ structural diagrams of the flow of concepts through a document. for long documents the subject could be shown at the center, with the various ideas radiating outwards. Branches and sub-branches indicate the hierarchical relationships between ideas, and visual cues are used to associate ideas with easily recalled symbols success criteria: can you map all the ideas in the document to the page map?
