1. 3.1.6 – Application software used for presentation and communication of data Presentations: Navigation Methods

2. This presentation aims to • Help you understand how to compare and give advantages and disadvantages of different modes of navigation: • Manual transition • Automatic transition • And identify and give examples of when the use of each method is more suitable.

3. This presentation also aims to • Help you understand how to describe non-linear and hierarchical presentations giving the advantages and disadvantages of each. • It also aims to help you to identify and give examples of when each may be more suitable.

4. Introduction • Presentations usually consist of more than one slide! • Slides can be navigated both manually and automatically… • But they can also be shown in one particular order or in an order that the user wants at the time of delivery.

5. Manual transitions • Manual transitions involve some form of user interaction. • The user determines when slides change. • Also, if there are different elements to a slide, such as bullet points, the user can dictate when those lists appear. • This is useful especially in a learning capacity as the presenter is able to take questions before continuing to the next slide.

6. Automatic transitions • Timings can be set up to automatically display slide elements and to change to the next slide. • The timings need to be set up to give the user enough time to read and digest the content. • These kind of presentations are suitable during exhibitions, open evenings and other similar events. • It is not often suitable to have a presenter speaking just in case they fall behind…however, narration clips can be included to speak during the slide!

7. Activity • Complete the following table: • Describe two advantages of using manual transitions for a presentation. [4 marks] • A presentation is to be shown during a school open evening to promote a subject. Identify, justifying your choice, the most appropriate transition method. [3 marks]

8. Linear • Basically…slides are shown in one order…each slide is displayed one after the other. Slide 1 Slide 2 Slide 3

9. Non-Linear • Slides can be shown in any order. • Buttons can be used to jump around slides in any order…even going back to slides that have already been shown. • This provides a level of flexibility…especially when presentations are shown to different audiences with different needs. • Entire sections can be missed out!

10. Non-Linear Slide 1 Slide 2 Slide 3 Slide 4 Slide 5

11. Hierarchical • Users can choose which slides to go to, but some slides can’t be accessed when certain choices are made. Slide 1 Slide 2 Slide 3 Slide 4 Slide 5 Slide 6

12. Activity • Complete the following table: • Describe two advantages and one disadvantage of the non-linear presentation structure. [6 marks] • Identify one situation where the use of a hierarchical presentation structure would be appropriate. [1 mark]
