Color: A well thought out color palette is needed to help those who may be color blind. Don't just rely on color to identify key elements of your interface. If this is the case, include text to help these areas so that all users can interpret the displayed information and navigate smoothly.
Navigation: clear indicators and short task flows allow for smooth navigation. The buttons must be consistent, especially those called to action, and clearly labeled. Menu bars and search boxes should also be placed in a similar format to logically guide users through their platform without problems and without confusion.
Keyboard accessibility: consider those who cannot use the mouse. This means designing the site so that users (if necessary) can navigate using only the keyboard. For example, using several buttons, including arrows, spacebar and enter. This is especially important for those with mobility difficulties.
Messaging: messaging must be carefully thought out. Some users may have reading difficulties, so you should think about the text format. Speak in simple English, do not use long sentences or paragraphs and stay away from italics and uneven spacing. Also, think about the color and font, is it readable?
Audio and video: interactivity should be included, where appropriate, in any design strategy. It is important to remember that including audio or video requires the use of accessible functions, especially for platforms in the public sector. Users must be able to pause / stop, adjust the volume and control the subtitles. Subtitles are also a good idea to accommodate deaf users, as well as to include text versions of audio files. Remember that the new public sector regulations will not affect live / prerecorded audio and video published before September 23, 2020.
