Layout and Composition
Grid systems: Use grid systems to create a consistent and organized layout.
White space: Use white space effectively to create visual breaks and improve readability.
Alignment: Align elements consistently to create a sense of order.
Proximity: Group related elements together to create a visual connection.
Contrast: Use contrast to draw attention to important elements.

Hierarchy and Emphasis
Visual hierarchy: Use size, color, and placement to create a hierarchy of importance within your design.
Focal point: Create a clear focal point to guide the user's attention.
Emphasis: Use techniques such as bolding, highlighting, or animation to emphasize important elements.

Chapter 5: Interaction Design

Interaction design focuses on how users interact with a product or service. A well-designed interface should be intuitive, easy to use, and enjoyable.



Usability Testing and Evaluation
Usability testing: Observe users as they interact with your product or service to identify usability issues.
Heuristic evaluation: Evaluate your design against a set of usability heuristics, such as Nielsen's heuristics.
A/B testing: Compare different versions of a design to see which performs better.

User Flow and Navigation
User flow: The path a user takes to complete a task.
Navigation: The structure and organization of your interface.
Breadcrumbs: Show users their current location in the navigation hierarchy.
