What does a macro rule refer to in interaction design?

A macro rule in interaction design refers to a guideline for overarching user actions. This concept encompasses the larger patterns and principles that guide how users interact with an application or a system. Macro rules are essential because they help establish consistent behaviors that users can rely on, allowing for a more intuitive and cohesive experience.

These rules take into consideration the overall flow of user tasks and the broader goals that users aim to achieve, rather than focusing on minute details of interface design or single interactions. By understanding and applying these overarching guidelines, designers can enhance usability and create more effective user experiences, making it easier for users to navigate and fulfill their objectives within an application.

The other options focus on aspects of design that are either too granular or specific to visual elements, rather than the larger user interaction strategies that macro rules address.
