Animation in Interfaces: 7 Fundamental Principles of UX Animation

Animation is a design tool that makes abstract digital entities tangible and familiar. This article covers the seven main principles of animation to consider in any use.

Research Highlights

Studies show we often embellish stories to make them more engaging and memorable, using time and movement to bring them to life. Animation not only makes stories believable but also helps us understand and trust the digital “magic” around us. Analog systems like bikes and toasters are predictable, instilling confidence.

Why Animation Matters

Arthur Clarke's third law states, "Any sufficiently advanced technology is indistinguishable from magic." While appealing, magic can be unsettling if it operates beyond our understanding. Digital systems, with their seemingly limitless possibilities, need animation to make their workings comprehensible and familiar.

Key Principles of UI Animation

Animation makes abstract digital entities tangible and familiar. Here are seven key principles to consider:

Timing: Choose the right moments for animation. Proper timing brings inanimate objects to life and conveys specific moods and personalities.

Pacing: Control the speed of movements. Slower pacing makes actions more deliberate, while faster pacing can convey urgency.

Staging: Prepare users for changes with subtle animations. Highlight important actions to guide users’ attention.

Follow-Through: Add realism with secondary motions. Objects should move fluidly and realistically, reflecting physical forces.

Secondary Action: Enhance primary actions with subtle background animations, making interactions more engaging and understandable.

Overlapping Action: Animate groups of elements with slight delays to show logical connections and reduce cognitive load.

Appeal: Use animation to create emotional connections. Exaggerated features and unique movements make digital interactions more memorable.

Practical Applications

In traditional animation, elements like timing and easing create realistic movements. Digital interfaces benefit from these principles by making changes more human and comprehensible.

Timing and Pacing: Proper timing can convey relationships between elements. Easing functions create natural accelerations and decelerations.

Staging: Micro-movements prepare users for upcoming changes, reducing confusion.

Follow-Through: Realistic secondary motions, like a slight bounce after a stop, enhance realism.

Secondary Action: Subtle animations in the background emphasize main actions without distracting users.

Overlapping Action: Animating elements with slight delays shows their interconnectedness and maintains visual harmony.

Appeal: Emotional animations, like a pulsing heart when liking a post, make digital interactions more engaging.

Conclusion

Using these animation principles, you can make digital interactions more predictable, human, and enjoyable. Whatever project you’re working on, leveraging these principles will help you create outstanding animations.
