Digital Signage, or the slides that appear on closed-circuit televisions across campus, needs to follow the Title II regulations and meet WCAG 2.1AA guidelines. As long as there is no wayfinding or touch interactivity, use the following as a guide.
Content
Keep your message and content short and straightforward, and provide a link or code to a webpage for more information. Too much content will require a small font size, making it difficult to read (both due to font size, and the amount that needs to be read before the slide changes).
Legible Text
Use simple fonts that are clear and easy to read, avoiding script or overly complicated fonts. Make sure that you have enough contrast between the font color and the background color.
Avoid text on top of photographs or "busy" backgrounds, as that will not have enough contrast.
Captions
Where applicable, with video or other audio displays, be sure to use captions or transcripts for those with hearing impairments.
Color
Use colors that meet the contrast requirements, and use a tool like WebAim Contrast Checker to confirm they meet WCAG 2.1 standards. This ensures those with vision impairments, like low vision or color blindness, can still read the information.
Don't rely solely on color to convey information; ensure that there is another visual cue, such as an icon or text.
Avoid Flashing Elements
Don't include video or animations that flash or rapidly change.
"Squint Test"
Squint at the screen and see if the most important information can still be read.
