principles of interactive design

Consistency is key in interactive design. Design elements like color palette, spacing, terminology, and style of content and imagery should remain stable throughout an experience to avoid distracting users from the core message. Visibility guides users through a series of tasks by indicating available actions and contextual information. Learnability means interfaces may require learning initially but become easier with use. Predictability creates a sense of comfort for users by making the experience foreseeable and feedback communicates the results of interactions to signal success or failure.
