Diversity starts with equity and inclusion.
Things to consider:
Your event
Does is represent diverse perspectives? Have invitations been made to members of underrepresented groups? Is your panel of speakers representative of the region’s people?
Have accommodations been made to prevent the marginalisation of people on the basis of (including, but not limited to) age, gender identity/expression, disability, socioeconomic status, religious beliefs, education level, race or ethnicity?
Some examples include: accessibility ramps, livestreams, gender neutral bathrooms, name tags with spaces for pronouns, quiet rooms, breastfeeding rooms and prayer rooms.
Always list the accommodations made, and ask for anything you may have missed during the application process.Have a land acknowledgement, which, when possible, is delivered by an indigenous, native or aboriginal member of the region (who is also an event attendee).
Your presentation/publication/media/platform
Visual & Written:
Colour blind-friendly images with different textures/shapes
High contrast text and elements
Use sans serif fonts such as Helvetica, Calibri or Arial.
Text and images large enough for those with limited vision (text minimums - ppt: 24 pt, written books/articles: 12pt, web: 16 px)
Include alt text for all images and schematics for those using screen readers (either use in-image function or include the image description)
Reduce visual complexity as much as possible
Designing with enhanced zoom or magnification features in mind (ensure all test is resizable to at least 200%)
Provide clear and succinct summaries, captions and titles
Offer plain text alternatives, where possible
Use Hierarchy and focus in design
Minimise motion, animation, flashing or repetitive motions
Ensure UI components are correctly marked up for assistive technologies (such as voice control software and physical switch controls)
Ensure your UI components are functionally accessible from a keyboard (ie content should be able to be accessed without a mouse)
Aural:
Include captioning or subtitles on all video content
Use a live audio captioning function for all live presentations to assist d/Deaf and hard of hearing individuals, and non-native language speakers (programs such as Google slides and Microsoft PowerPoint both have these functions built in)
Where possible, have a sign language interpreter on stage
Oral:
Always use a microphone when available
Avoid the use of field-specific jargon and acronyms
Please note these lists are just a few options to assist users who may have: limited or low vision, functional/motor impairment, cognitive disabilities and/or ADD/HDAD.
