How to Create a Non-linear PowerPoint Presentation

Sometimes even the most engaging presentations are not interactive enough. The reason is that they follow a fixed path instead of meeting individual needs. In this article, we will show you how to create non-linear presentations that encourage audience participation

What is a non-linear presentation?

 Non-linear presentations allow you to navigate through material without having to follow a strict order. They give presenters the ability to jump over slides, depending on what information is most relevant in a certain situation.
Non-linear PowerPoint presentations resemble a website, in that one slide can easily lead to another,  the way hyperlinks work on the Web. Glide through your content in any direction to present ideas in greater or lesser detail and avoid demonstrating irrelevant information.

 

How to create non-linear presentations in PowerPoint

With PowerPoint, you can either turn an already existing linear presentation into non-linear, or create it from scratch. The key to non-linear navigation in PowerPoint is the ability to move back and forth from the home slide. This can be done by inserting hyperlinks and action buttons.

If you already have a presentation, launch it in PowerPoint and then create a blank slide that will represent its table of contents. Type the name of the first section and add a hyperlink to it. In order to do so:

 

1. Highlight the name of the section
2. Go to the Insert tab at the top and choose Hyperlinks;
3. In the open box, choose Link to -> Place in This Document;
4. Select the first slide of your section 

Each section of your presentation may have more than one slide. The hyperlinked text will lead to the indicated slide, no matter in what order it appears in the presentation. Repeat this process to provide all sections with relevant slides.

In order to come back from any point of your presentation to the table of contents, use action buttons. In order to do so:

1. Choose the slide on which you wish to place an action button.
2. Go to the Insert tab and select Shapes;
3. Go to the bottom and choose Action Button: Home (with the picture of a house);
4. Click and drag the cursor to create a square button on the slide;
5. In the open box, click Hyperlink to and select the home .
