- tweaked text under "Ensure slides, handouts, and other electronic material for participants is accessible."
- added: Give speakers accessibility requirements and guidance. Tell speakers that you expect their material and presentations to be accessible to people with disabilities. Consider including accessibility requirements in any contracts. Consider pointing speakers to this page (www.w3.org/WAI/training/accessible) for guidance, including the link in any speaker guidelines, e-mails, web pages, etc.
- added: (for organizers & speakers) notes with each <h2>

Analysis
Audience:
- Presenters, trainers, event organizers, and such of any topic (not just accesibility)
Scope:
- Primarily covers accessibility considerations for basic face-to-face presentations, e.g., presentations at conferences
- Out of scope (not include in this doc):
- general presentation guidance (e.g., find out audience's background in advance, engage the audience, etc.)
- tool-specific instructions (e.g., how to add alt to image in AcmePresentTool)
- online presentations and training, live virtual classroooms with multi-channel interaction
- guidance specific to presentations on the topic of accessibility (e.g., demo a screen reader. Those are covered in the other pages of the update-in-progress Training Resource Suite.)
- make event announcements, registration, and such accessible
- Include links to a few select WAI resources because we hope lots of people will come to this page even that aren't aware of WAI, and so this is an outreach opportunity

Draft-in-progress changelog
Changed 15 May
- Under "Planning the Event" under Consider accessibility when planning the schedule. changed first sentence to: Some people need more time to get from room to room; for example, because the accessible route is longer, or they move slowly.
- changed <dl>s to <h3>s and <p>s (except in the terminology section)
- added more anchors throughout
Changed 11 May - 11 May change-marked version
- Edited:
Consider accessibility when planning the schedule.
For example, consider accessible routes between meeting rooms, and provide sufficient time between sessions for people who walk slowly. Schedule sufficient breaks. People might need to take care of medical needs during breaks. Keep to the schedule as much as possible, and inform participants ahead of time of any changes. - Moved example of presentation material from For More Info to here:
Make provided material accessible.
If you are giving participants material, make it accessible. See provide accessible material above. An example of presentation material provided in both presentation format and web format (HTML and CSS) is linked from the top of the page after "The Benefits of WCAG 2 presentation is available in 2 formats:". - Moved "Guidance on Interacting with People with Disabilities is available online." from For More Info to under Be Open to Accessibility Issues and Respect participant's needs.
- Added Checklist for Existing Facilities after "There are checklists online to help ensure a facility is accessible," under Ensure the facility and area is accessible to speakers and participants.
- (Considered adding a Note at the bottom like "These are not formal guidelines, nor official requirements. They are just suggestions of things for you to consider." - then decided not to.)
Changed 5 May
- Basics section: added last sentence: Be open to diversity in your audience and any accessibility needs.
- For Ensure the facility and area is accessible. added: Provide accessibility information to speakers and participants, such as the accessible routes between meeting rooms or facility maps in braille. Let speakers and participants check out the rooms in advance to suggest optimum positioning of the speaker, screen, seating, etc.
- At first reference of ALDs and CART, added: (Assistive listening devices (ALDs), hearing loops, or induction loops; and Computer Aided Real–Time Captioning or Communication Access Realtime Translation (CART) are explained in the Terminology section.)
- In Planning the Event section, added: Consider accessibility issues when planning the schedule. For example, provide sufficient time between sessions for people who walk slowly or take accessible routes between different meeting rooms. Keep to the schedule as much as possible, and inform participants ahead of time of any changes.
- Edited: Provide material ahead of time, as requested.
- At end of Preparing Slides and Projected Material section, added: Provide accessible material. See provide accessible material above.
- Under Respect participant's needs. added: People might have accessibility needs that you haven't thought of.

- Change section headings to:
- Planning the Event (for organizers)
- Providing Accessible Material
- Planning Your Session (for speakers)
- Reorganized Providing Accessible Material section into 2 points
- Edited: "Use multiple communication methods for different learning styles.
Some people can better understand verbal information, others pictures and diagrams, and others text." - Added: "Give people time to process information.
Pause between topics. When you ask if anyone has questions, some people with cognitive disabilities will need extra time to form their thoughts into words." - Added: "... Note that if you ask "Can everyone hear me OK?" some people might be uncomfortable saying that they cannot.
Ensure all relevant sound is audible through the sound system...." - Added: Arrange for ALDs/hearing loops, interpreters, and/or CART writers, as needed.
(These are explained in the Terminology section.) Work with participants and service provides to ensure that important details are taken care of; for example, power and a screen are provided for CART; microphones and speakers laptop sound is connected to the ALD/hearing loop system. - Added: "Ensure adequate sound system, and arrange for microphones.
Often wireless lavaliere microphones are best so that speakers can move around. When the audience will be commenting or asking questions, provide microphones for them." - Added speakers to "Ask speakers and participants if they have accessibility requirements."
- Deleted <dt> "Use appropriate background and text colors." and merged with previous "Use sufficient color contrast."
- Minor edit to last sentence under "Ask if participants have accessibility requirements."
- Added "Guidance on Interacting with People with Disabilities is available online." in For More Information section.
- Changed "presenter" to "speaker" in a few places.
Comments and disucssion points for 16 April
# Comment 1:
- Location: Ask if participants have accessibility requirements
- Priority: minor edit, editor's discretion
- Text: "send an email to internal training participants, etc"
- Comment: it is unclear what "internal training participants" are
- Suggestion: "For example, include a question on registration forms and invitations for conferences, meetings, and trainings, to invite participants to include specific accessibility requests" (see #2)
Editor: When I’m doing training within an organization, I might not have registration forms or invitations. I want the examples to get people thinking, not cover every point. I want to avoid “conferences, meetings, and trainings” in the examples. I think “invite participants to include specific accessibility requests” needs to be a separate point, not part of the example.
Changed “...send an email to company-internal training participants...”
# Comment 2:
- Location: Ask if participants have accessibility requirements
- Priority: medium, may need some discussion
- Text: "Invite participants to include specific requests, for example, seating small discussion groups in a circle so you can see each other is useful for people who are hard of hearing"
- Comment: example may be too complex or daunting to readers, especially since it is the first specific example in the document
- Suggestion: remove example or replace with simpler ones if needed
Editor: I’m missing why it is complex and daunting. Also note that a commenter requested that seating people in a circle was required as a main point (a <dt>). The commenter is satisfied with this compromise; however, I’m sure she would not like the example removed all together.
Changed added semi-colon to separate the example more: “Invite participants to include specific requests; for example, seating small discussion groups in a circle...”
*EOWG for discussion*: Can this example be made less complex and daunting? Or is it OK? Can this point be made elsewhere? Should a simple example be added?
# Comment 3:
- - Location: Ensure the facility and area is accessible
- Priority: minor edit, editor's discretion
- Text: "When feasible, allow participants to check out the room in advance to ... "
- Comment: "when feasible" sounds like an obligation
- Suggestion: consider "if possible", "when needed", or "if requested"; or drop this sentence entirely
Editor: I think “when feasible” is less of an obligation than the other suggestions; however, I’m OK with “possible”.
Changed “When possible,...”
# Comment 4:
- Location: Ensure the facility and area is accessible
- Priority: medium, may need some discussion
- Text: entire paragraph
- Comment: (1) built-environment accessibility is more than wheelchair accessibility, (2) paragraph is complex because of AV considerations
- Suggestion: split paragraph into two, physical and AV accessibility; for example as follows:
[[
* Ensure the venue is physically accessible.
For example, inquire if all relevant rooms and facilities, including the building entrance, meeting room, break rooms, and bathrooms meet accessibility standards. Ensure access for wheelchair users, people who can not walk for long distances or climb steps in a theater or podium, and people who may not be able to see or use elevator buttons, etc.
* Check all audio-visual (AV) systems.
Ensure adequate sound system, including working ALD/hearing loop with sufficient batteries as needed. Ensure that sound and screen display work with assistive technologies used by presenters, and for remote or present CART writers and interpreters as needed.
]]
Editor: We didn’t even have these points in the early versions, because we didn’t want to get into that level of detail. Also, this is page is targeted more for speakers, rather than event organizers. In any case, I think it is not worth expanding the length of the document. Remember that Judy commented that the document is already long and potentially overwhelming.
Changed Added to “wishlist” in analysis/requirements/changelog: separate guidance for speakers and for organizers.
*EOWG for discussion*: Can we justify expanding the document to add this?
# Comment 5:
- Location: Arrange for a microphone
- Priority: minor edit, editor's discretion
- Text: new text proposed
- Comment: add something about sufficient microphones
- Suggestion: "Provide microphones for all speaker and for the audience as needed, and ensure connection to the ALD/hearing loop system"
Editor: I think not worth adding length and complexity.
Changed To plural: “Arrange for microphones.” and “...the presenters...”
# Comment 6:
- Location: Work with CART writer and interpreters
- Priority: minor edit, editor's discretion
- Text: "Work with CART writer and interpreters"
- Comment: preference for edits suggested below
- Suggestion: "Arrange for CART writer and interpreters as needed"
Editor: Again, this is written more for the speaker than the organizer. The explanation is “Give them material in advance and be available to answer any questions.”
# Comment 7:
- Location: Provide material ahead of time
- Priority: minor edit, editor's discretion
- Text: entire section
- Comment: it is unclear what material to provide ahead of time
- Suggestion: consider spelling out, like "provide slides, hand-outs or other material to CART writers, interpreters, and participants as needed"
Changed “Provide slides, handouts, and other material to participants, CART writers, and interpreters, as needed.”
# Comment 8:
- Location: Provide material ahead of time
- Priority: minor edit, editor's discretion
- Text: "More about accessible material below"
- Comment: make link text same as the heading text to help associate
- Suggestion: "More about providing accessible material below"
Changed (More about _providing accessible material_ is below.)
# Comment 9:
- Location: new (after "Provide material ahead of time")
- Priority: medium, may need some discussion
- Text: new text proposed
- Comment: add something about appropriate agenda planning
- Suggestion:
[[
* Provide a reliable agenda.
Ensure sufficient breaks, include sessions for orientation and logistics, provide information about room location, and keep to the scheduled time.
]]
Editor: While I agree this is good info, I think it is not worth expanding the length of the document. (Also, if we did, I wonder if we’d need to say why this is an accessibility issue, rather than just good practice for all (like general usability :).) Remember that Judy commented that the document is already long and potentially overwhelming.
*EOWG for discussion*: Can we justify expanding the document to add this?
# Comment 10:
- Location: Use appropriate background and text colors
- Priority: medium, may need some discussion
- Text: entire section
- Comment: is this an accessibility requirement?
- Suggestion: may need to use a better example than "bold"
Editor: Yes, background and text color is a significant issue for people with some types of low vision. This was previously combined with “Use sufficient color contrast.” but then separated to keep each explanation simple.
Re: “...ensure that the weight of text is sufficient (for example, bold).” ummm – bold is the easiest way to have heavyweight text. I can’t think of a better example.
# Comment 11:
- Location: Use multiple communication modes
- Priority: minor edit, editor's discretion
- Text: entire section
- Comment: unclear because "multiple communication modes" is jargon and the text does not really clarify what the speaker needs to do
- Suggestion: consider a different title and adding one or two more words about what it means for the speaker, that people have different learning modes/preferences
Editor: Humm - I think "Some people will learn better verbally, others with pictures and diagrams, and others with text." explains the possible jargon; and "Use multiple communication modes." tells the speaker what to do. I think adding more (such as: "Therefore, use speech, text, and images where possible.") would be unnecessary clutter and complexity.
EOWG for discussion: Any suggestions for less jargony title than "Use multiple communication modes"?
# Comment 12:
- Location: Offer slides, handouts, and other material in accessible formats
- Priority: minor edit, editor's discretion
- Text: entire section
- Comment: to complex and hard to follow
- Suggestion: break up into individual steps, such as:
[[
* Provide alternative formats for slides, handouts, and other material.
Participants might need material in alternative formats such as large print or braille; however, if they get the material in advance electronically, they might not need it in print at all. Electronic formats such as HTML (that is, web page format) and RTF are often the most flexible to meet different people's needs.
* Ensure slides, handouts, and other electronic material is accessible.
Ensure your materials are accessible, for example, provide alternative text for images. [@@Web?HTML?Online?] Material should meet WCAG 2.0, at least Level AA. (Some other resources are listed under For More Information below.)
]]
Editor: Hummm - I'm not sure which is simplier.
EOWG for discussion: Is is better as is? Or split up as above? Or other?
# Comment 13:
- Location: Speak clearly
- Priority: minor edit, editor's discretion
- Text: new text proposed
- Comment: add other aspects of speaking clearly
- Suggestion: "Avoid using jargon, explain acronyms and uncommon words, and speak slowly so that people understand you better"
Editor: I think these are two different points. In response to this and Comment 19 below I added a <dt>.
Added: Use simple language.
Avoid or explain jargon, acronyms, and idioms. For example, expressions such as "raising the bar" can be interpreted literally by some people with cognitive disabilities and can be confusing.
# Comment 14:
- Location: new (after "Describe other visual information")
- Priority: medium, may need some discussion
- Text: new text proposed
- Comment: what about sound?
- Suggestion:
[[
* Describe subtle audio information.
Describe subtle cues conveyed through audio. For example, explain the feedback cue that is expressed through a sound clip.
]]
Editor: Whatever method is used to provide auditory information for those who cannot hear it, should provide all audio info, e.g., sign language interpreter. (btw, I don’t understand “explain the feedback cue that is expressed through a sound clip.”) In any case, I think it is not worth expanding the length of the document for this point. Remember that Judy commented that the document is already long and potentially overwhelming.
*EOWG for discussion*: Can we justify expanding the document to add this?
# Comment 15:
- Location: new (after "Describe other visual information")
- Priority: medium, may need some discussion
- Text: new text proposed
- Comment: what about sound?
- Suggestion: add a new section about describing audio too, for example after playing a sound file (or demo'ing a screen reader etc.)
[[
* Expect the unexpected.
People have different needs and requirements; they may need to use magnifying glasses, photograph the screen, record your voice, leave the room, eat, or drink.
]]
Editor: This feels too general. I think it is not worth expanding the length of the document for this point. Remember that Judy commented that the document is already long and potentially overwhelming.
*EOWG for discussion*: Can we justify expanding the document to add this? If so, how can we reword it to be more specific?
# Comment 16:
- Location: Providing recording afterwards
- Priority: minor edit, editor's discretion
- Text: new text proposed
- Comment: consider broadening beyond recordings alone
- Suggestion: add something about making the slides, handouts, and other material also available after the session.
Editor: We say earlier to provide material before the session, and to make it accessible. This section is only “Make media fully accessible.”
# Comment 17:
- Location: Make media fully accessible
- Priority: minor edit, editor's discretion
- Text: "WCAG"
- Comment: previous link to the same page was called "WCAG 2.0" and did not have acronym tags
- Suggestion: unify both approaches
Editor: done.
# Comment 18:
- Location: Additional Benefits
- Priority: minor edit, editor's discretion
- Text: "Presentations that are accessible to people with disabilities have additional benefits. For example"
- Comment: say something brief about the larger audience reached by more inclusive presentations (even if this somewhat repeats the bcase doc)
- Suggestion: "Presentations that are accessible to people with disabilities are inclusive to many more audiences including people who are new to the subject matter, people who are not fluent in the language, or people who have varying learning styles. Accessible presentations also have additional benefits, including:"
Changed: “Presentations that are accessible to people with disabilities are inclusive to many more audiences, including people who are not fluent in the language and people with different learning styles. Accessible presentations also have additional benefits, including:”
# Comment 19:
- For speakers: Avoid or explain jargon and idiomatic expressions. Expressions such as "raising the bar" can be interpreted quite literally by some people with learning disabilities, causing confusion, and additional cognitive load.
Added: Use simple language.
Avoid or explain jargon, acronyms, and idioms. For example, expressions such as "raising the bar" can be interpreted literally by some people with cognitive disabilities and can be confusing.
# Comment 20:
- For speakers: Count to 5 slowly (to yourself) after asking the audience if they have any questions. People often need time to formulate their questions into words.
Editor: While I agree this is good info, I'm not sure it is worth expanding the length of the document. Remember that Judy commented that the document is already long and potentially overwhelming.
EOWG for discussion: Can we justify expanding the document to add this or not?
If yes, what's the simpliest way to do it? e.g., expand "Speak clearly." to "Speak clearly and slowly, and give the audience time to process information" and then under that add: "For example, when you ask the audience if they have any questions, some people with cognitive disabilities will need extra time to formulate their questions into words." Or other?
# Comment 21:
- For planners: Require microphone use by speakers. Frequently presenters are shy of the microphone and ask the audience if they can hear well enough. Sometimes people do not want to speak up to say they cannot hear well enough, especially as the speaker often asks the question is a louder voice than the rest of their talk.
Editor: We don't have a separate section for planners. We already have "Use a microphone.
Even in a small room, some people might need the audio electronically, including people using ALD/hearing loop and remote CART writers."
While I agree the additional information about people not wanting to speak up if they can't hear well enough is good, I think it is probably not worth expanding the length of the document to add it.
EOWG for discussion: Can we justify expanding the document to add this or not?
# Comment 21:
- Be careful not to sound like CART is substitute for sign lanauge interpreter.
Changed: Put sign language before CART where they are togethering.
Added at end in terminology: "Note that sign langauges are different from spoken languages and there is not a one-to-one translation."

Archive of old info
- Organization options:
- By topic
- pro: good for unknown audiences, when you don't know and could have participants with different disabilities
- pro: considerations grouped by when & who does them
- pro: encourages universal access, instead of limited accomodation for one disability
- idea: if organized this way, could have icons on each item for each disability type, so those with known participants can skim for specific issue
- By disability
(as is 9 March 2010 draft)
- pro: good for known audience situations (when presenters know they have a participant with a particular disability)
- con: editor and several in EOWG do not like categorizing by disability for various reasons
- By topic
