Interaction Principles
Core interaction design principles
Affordances
Define what actions are possible with an object or interface based on the capabilities of the user. Affordances help you know what action to take.
Conceptual Model
An explanation, usually highly simplified, of how something works, which is formed through experience, training and instruction.
Constraints
Physical, semantic, cultural and logical constraints guide our actions and aid in interpretation.
Discoverability
The ability to discover what a system does, how it works, and what operations are possible. Discoverability is key to learning what's possible. It defines the ease at which users can find new content or features and directly affects their ability to complete specific tasks. It results from the appropriate application of affordances, signifiers, constraints, mappings and feedback.
Feedback
Feedback communicates the current state of a system or object. Feedback allows the user to feel in control and take appropriate actions to reach their goal, as well as building trust that the system works as intended.
Mapping
The relationship between the elements of two sets of things.
Signifiers
Signifiers are visible or audible clues that communicate the appropriate action within a system.
