An app normally has many moving parts, for example, transitions between views--panels that appear as you click on a button--animations and images that react to a touch gesture, and many more. Deciding how each of those elements will move is an important design decision to consider.
When prototyping, you can explore different approaches for using motion to help achieve your goals. Motion can be helpful at different levels:
- Motion helps to explain: The way items move can tell you about the rules of the digital world they live in, thus helping users to understand these rules better. Clarifying the information hierarchy or providing orientation cues can be more effective when it is communicated intuitively through motion rather than when explained with words. For example, friction in the scrolling movement of a list of items can be used to communicate...
