Answers
Adding movement to your slides through the use of animation or slide transition effects is risky. Movement distracts the audience from your message. Here are suggested approaches for using animation and slide transitions in a professional presentation.
Animation Effects
A number of organizations have “banned” animation and animation has a poor reputation amongst many presenters and audiences. Why has this happened? Because too often presenters use fancy animation effects like twirling, flying, or bouncing in an effort to “keep the audience paying attention”. These effects do not keep the audience paying attention, they annoy and distract the audience.
Is animation ever appropriate? Yes. It is useful when you want to build the different parts of a slide in order to focus the audience as you explain your point. Instead of having all of the elements appear on the slide at the start, you build each piece as you speak about it so you can give context before they come to a conclusion.
Use only simple animation effects, such as Appear, Fade, Dissolve, and Wipe instead of the crazy motion effects. This way the effect does not distract from the message you are delivering.
