Use more graphics and less text for better presentations

According to The Extreme Presentation Blog, "extensive research confirms that when you project slides filled with bullet points while speaking at the same time, your bullets and your voice compete with each other, with the result that your communication effectiveness is worse than either if you projected your slides and asked your audience to read them (while you keep quiet) or if you spoke without any slides at all.

"If you are going to use visuals, make sure that they support, rather that vie with, your spoken comments. One way to do this is to use more graphics and less text (several research studies conclude that while voice and text compete with each other, voice and graphics reinforce each other)."
