Squash & Stretch: Use bounce effect sparingly for playful emphasis. Scale animations should feel elastic not mechanical. Key numbers can "pop" with slight overshoot.
Anticipation: Fade out previous content before new appears. Slight pause after slide transition before builds begin. Dim existing elements before highlighting new ones.
Staging: One focal point per moment. Dim completed content to 30-50% opacity. Use motion to direct eye path. Build complex diagrams piece by piece.
Straight Ahead vs Pose to Pose: Morph transitions (Keynote Magic Move, PowerPoint Morph) create fluid straight-ahead motion. Standard builds are pose to pose. Use morph for transformation stories.
Follow Through & Overlapping: Build related items with 0.1-0.2s delays. Supporting text follows primary graphic. Bullet points stagger naturally. Don't animate everything simultaneously.
Slow In / Slow Out: Always use ease-in-out or ease-out. Never linear—looks robotic. Keynote: "Ease In & Out". PowerPoint: use custom motion paths with curve handles.
Arc: Motion paths should curve naturally. Elements entering from sides arc inward. Exit animations arc toward edges. Straight lines feel mechanical.
Secondary Action: Icons animate alongside text reveals. Arrows appear as relationships are explained. Background subtle shifts support primary content.
Timing: Text builds: 0.3-0.5s. Graphic reveals: 0.4-0.6s. Slide transitions: 0.5-0.8s. Complex sequences: 0.2-0.3s between elements. Match pacing to speaking rhythm.
Exaggeration: Use scale emphasis for key points. Pulse effect for critical numbers. Shake for contrast/disagreement. Reserve exaggeration for truly important moments.
Solid Drawing: Maintain grid alignment during motion. Consistent transform origins. Elements should feel anchored to the slide structure.
Appeal: Purposeful animation builds credibility. Excessive motion distracts and annoys. Every animation should serve communication.
Squash & Stretch（挤压与拉伸）：谨慎使用弹跳效果以营造趣味性强调。缩放动画应具有弹性而非机械感。关键数字可通过轻微过冲实现“弹出”效果。
Anticipation（预备动作）：在新内容出现前淡出旧内容。幻灯片过渡后稍作停顿再开始构建动画。在高亮新元素前调暗现有内容。
Staging（舞台布局）：同一时刻仅保留一个焦点。将已展示内容调暗至30-50%透明度。利用动效引导视线。分步骤构建复杂图表。
Straight Ahead vs Pose to Pose（逐帧动画/关键帧动画）：形变过渡（Keynote Magic Move、PowerPoint Morph）可创造流畅的逐帧运动效果。标准构建动画属于关键帧动画。使用形变过渡讲述转化类故事。
Follow Through & Overlapping（跟随动作/重叠动作）：为相关元素设置0.1-0.2秒的延迟动画。辅助文本跟随主图形动画。项目符号自然交错出现。不要同时为所有元素添加动画。
Slow In / Slow Out（缓入缓出）：始终使用缓入缓出或缓出效果。切勿使用线性运动——会显得机械生硬。Keynote：选择“Ease In & Out”。PowerPoint：使用带曲线手柄的自定义运动路径。
Arc（弧线运动）：运动路径应自然弯曲。从侧边入场的元素沿弧线向内运动。退场动画沿弧线向边缘移动。直线运动显得机械。
Secondary Action（次要动作）：图标随文本展示同步动画。在解释关系时显示箭头。背景的细微变化为主内容提供支持。
Timing（时机把控）：文本构建：0.3-0.5秒。图形展示：0.4-0.6秒。幻灯片过渡：0.5-0.8秒。复杂序列：元素间间隔0.2-0.3秒。节奏与演讲语速匹配。
Exaggeration（夸张效果）：对关键点使用缩放强调。对关键数字使用脉冲效果。用震动效果体现对比或反对。仅在真正重要的时刻使用夸张效果。
Solid Drawing（扎实构图）：运动过程中保持网格对齐。变换原点一致。元素应感觉锚定在幻灯片结构上。
Appeal（吸引力）：有目的性的动画可提升可信度。过多动效会分散注意力并引起反感。每一个动画都应服务于沟通目的。
