Presentations that are accessible to people with disabilities are inclusive to many more audiences as well, including people who are not fluent in the language and people with different learning styles.
Although a good presenter should adapt his presentation to the particular needs of his or her audience, we we propose these guidelines to help make every presentation more accessible from the start.
Make slides available before the presentation
For people with visual impairments, it is very useful to have access to the slides in good time before the presentation. This allows for them to prepare themselves for the presentation and maybe access the slides using some preferred software or tool, like a screen reader or braille translator. Therefore it is very good if you can provide the slides already before the conference for the organizers to provide them via e.g. the schedule, or per request, if this is possible.
Make text and important visuals big enough to be read even from the back of the room.
This applies to graphics on slides, videos, posters, and other non-electronic material.
Use an easy-to-read font face.
Simple fonts with consistent thickness are often easier to read from a distance (as opposed to fonts where parts of the letters are thin, like Times New Roman). Avoid fancy fonts that are difficult to read.
Use sufficient color contrast.
Color contrast guidelines and evaluation tools for web pages might be helpful to determine sufficient contrast (although the medium is different because those guidelines are specifically for web pages). Use appropriate background and text colors. Some suggest when presenting in a light room to display dark text on a light background. When presenting in a darkened room to display light text on a dark background, and ensure that the weight of text is sufficient (for example, bold).
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:".
Audio & video
Make media fully accessible — including audio and video.
For example, provide captions and/or transcripts as appropriate for audio, and provide audio description for videos as needed. Guidelines for media on the web is available in WCAG 2.0; it includes specific guidance such as providing an alternative for audio-only content (like podcasts).
During the presentation
And avoid speaking too fast, so participants and sign language interpreters (if present) can better understand you and keep up.
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.
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.
Also be in good light so participants can see your face when you talk, which helps some people hear and understand better. Be careful not to face away from the audience to read projected material.
Use a microphone.
Even in a small room, some people might need the audio electronically, including people using ALDs/hearing loops and remote CART writers. Note that if you ask "Can everyone hear me OK?" some people might be uncomfortable saying that they cannot.
Ensure that all relevant sound is audible through the sound system.
For example, if the audience doesn't have a microphone, repeat their questions and comments into your microphone before replying.
Cover all displayed text.
Say all of the information that is on each slide. (This does not mean that you have to read the slide exactly as it is, it just means that you cover the visual information in what you say.)
Describe pertinent parts of graphics, videos, and other visuals.
Describe them to the extent needed to understand the presentation. (You usually do not need to describe decorative images.)
Describe other visual information.
For example, if you ask a question of the audience, summarize the response, such as, Speaker: "If you make your websites fully accessible, please raise your hand."...then: "About half raised their hand."
