What is the connection between inputs and outputs referred to as?

The connection between inputs and outputs in interactive design is referred to as mapping. Mapping involves the relationship between user actions (inputs) and the corresponding responses or results produced by the system (outputs). A well-designed mapping makes it intuitive for users to predict the outcome of their actions, enhancing usability and overall user experience.

For example, when pressing a button on a touchscreen, the expected response—such as opening an application or changing a screen—should be evident and logical based on the design. Effective mapping ensures that users can quickly understand how their interactions will lead to specific results, thereby reducing confusion and increasing efficiency when using a system.

The other concepts like feedback, constraints, and visibility play important roles in design but refer to different aspects. Feedback concerns the information provided to the user about the result of an interaction. Constraints refer to the limitations imposed on the user's actions, and visibility relates to how well users can see and understand the elements available to them in the interface.
