If you want your presentation to run by itself—at a kiosk, for example—you can make it a self-playing presentation.
In a self-playing presentation, transitions or builds set to begin automatically occur just as they do during a normal presentation. Transitions and builds set to begin “on click” (when the presenter clicks) also happen automatically, after the amount of time specified in the Delay fields in the Document inspector. The values you specify in the Delay fields apply to all transitions and builds set to begin on click.
Although viewers can’t interact with these kinds of presentations, self-playing presentations can be stopped in the same way as other presentations (for example, by pressing the Escape key). To prevent viewers from stopping a self-playing presentation, remove their access to a keyboard or require a password to exit the presentation.
If the Document inspector isn’t open, click the Inspector button in the toolbar and then click the Document button.
In the Document inspector, click Document.
Choose Self-playing from the Presentation pop-up menu.
To specify how much time to wait before automatically starting transitions after a new slide is displayed, specify a value in the Transitions field.
To specify how much time to wait before automatically starting builds after a new slide is displayed, specify a value in the Builds field.
To set other options, including setting a password, use the Slideshow Settings checkboxes.
See Setting Slideshow Playback Options for details.
