Advanced interaction design is designing every micro-interaction: button press feedback, form validation, loading states, error recovery, animations, voice feedback. Mastery takes 4-5 weeks of prototyping, user testing, and feedback design. Senior interaction designers earn 20-30% premium because they reduce user confusion by 50%, improve conversion by 10-20%. It's rare: requires both design sensibility + understanding of psychology (affordances, feedback loops, mental models).
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).
