Tips for accessible electronic presentations:
- Use large font and image size (typically at least 24pt) in a neutral font, such as Sans-Serif (e.g., Arial, Calibri).
- Use patterns, labels, or shading in graphs instead of color-coding. Colorblind attendees may not be able to distinguish red from green bars.

Tips for video presentations:
- Use good lighting and speak so that your full face is visible.
- Enunciate clearly and eliminate background noise (e.g., silence email notifications).
- Verbally describe all images, charts, or graphs being presented. It is not necessary to detail every single element in the image, but the major points should be verbally clarified.
- Allow pauses between slides to give viewers ample time to process information.
