Differentiating sections visually lets the reader know when they’re transitioning into a new topic in your slidedoc. There are several visual mechanisms you can employ in your presentations to alert the reader they’re moving into a new section.
In physical documents, tabs help readers flip to a new section quickly. You can use visual devices that mimic tabs on your slides to help readers jump to any section from any page in your presentation.
The top of this slide clearly identifies you are in section 3.
Each section could be assigned its own color. Color bars on the very edge of a slide could change as you move from section to section, or the pages themselves could be flooded with bold colors in each section.
Side bars map back to the colors of the major section heads. Here you can see we’re in section 2 of 5.
As readers turn pages, a distinct page layout will stand out. For example, content pages tend to be white and full of text and images, so a distinct layout would use bold text or conceptual images.
This presentation uses a flood of color that is different from the white, content-filled pages. The contrast signifies that it’s a new section.
When content in a presentation fits together like a system or process, you can use a diagram as a navigation device. Show the sections demarcated and clearly labeled. Then, highlight the segment of the diagram that identifies the section you’re in.
Navigational diagrams help readers stay oriented. In this example, the lower left segment is highlighted to signify the section the reader is in.
