Know When to Animate
1/ Effective Animation shows how things work: Use animation and motion to control eye movement as you reveal how things are put together, explain changes, show direction, or illustrate sequence. If, for example, you used a stack of rectangles showing how parts of your software application fit together, you can provide information on one part at a time, without crowding the visual: When you click on a rectangle, have a “drawer” slide out from behind it to reveal details.
2/ Effective Animation creates contrast: to create contrast with animation, show several slides with no animation so that when you do animate, it stands out.
3/ Effective Animation looks natural: Just like actors on a stage, elements can enter your slide, interact, and then leave the scene. But the movement should seem natural and controlled, not busy and frenetic.
4/ Effective Animation does not annoy: Most content isn’t any clearer if you make it spin, twitch, or twirl. Gratuitous features like these just get on people’s nerves, so don’t waste time on them.
