There are 4 critical design components one must be aware of when creating visual presentations, whether it’s a PowerPoint presentation or an infographic. They are: Contrast, Alignment, Repitition and Proximity. Contrast relates to size and shapes of objects relative to each other, color, text direction, and light and dark values. Contrast keeps the eye active and engaged with the design. Alignment helps to organize disparate items on a page. It creates a logical path for the eye to follow and sets up a hierarchy of importance on the page or slide. Repetition enforces a sense of continuity and visual rhythm. Using the same sans serif font for headings and serif font for body text make for visually pleasing and easy to read text. Finally, Proximity allows for the grouping of like objects and incorporation of white space on a page. All four working together will aid in conveying the visual message you’re trying to deliver, in the most efficient manner.
I think of the four principles, Contrast may be the most important when designing materials for webinars. There’s usually not a lot of content on each slide, and the slides may not be up for that long. The webinar attendees have to quickly digest new information presented to them and you must make it clear what information is the most important on the slide. But realistically, it’s important to utilize all the priciples to create an effective visual presentation that gets the point across quickly and makes a lasting impression.
