Interaction Design Advanced

Interaction Design is designing the dynamics of a digital system: what happens when users perform actions and how the system responds. Every micro-interaction: button press feels responsive, form validation guides without frustrating, error messages explain what went wrong, loading states reassure that progress is happening. Advanced IxD understands psychology (affordances, feedback loops, mental models), accessibility (keyboard navigation, screen reader support), and craft (timing, easing, micro-animations).
