How should visuals be used to support a presentation without taking over the presentation?

Visuals can improve the quality and impact of any presentation by creating interest,illustrating points that are difficult to explain with words alone,adding variety,and increasing the audience's ability to absorb and remember information.Behavioral research has shown that visuals can improve learning by up to 400 percent because humans can process visuals 60,000 times faster than text.For all the communication power of visuals,however,don't make the mistake of thinking that your visuals are your presentation.Particularly when using software such as Prezi or Microsoft PowerPoint,communicators sometimes fall into the trap of letting the visuals take center stage.Remember that your message is the presentation,not your visuals; your visuals are there to help support and clarify what you have to say.
