Plan what happens before and after your presentation
What could they have done better? And what should you do if you are running a meeting that uses slides for one part but not others? Plan for it.
Before or after the slides need to be used, do one of the following:
a) Insert a black slide in the presentation and display it while the slides are not in use.
b) Press the "B" key on the keyboard to toggle to a black slide while they are not being used.
c) Add slides that simply indicate what this section is about, such as a slide with the speaker's name and title or a slide with a picture of a landscape while music is playing. Use these slides to add visuals to the other sections of the agenda so that there is a consistency to having a visual with each section.
By planning for how the projector and screen will be used throughout the entire time the audience is watching, you provide a seamless experience for the audience and don't have any distractions to take their focus away from the messages being presented.
