Interaction Design (IxD)

Design behavior, not just pixels. Master user flows, state changes, affordances, and cognitive load to create intuitive digital products.

Interaction Design (IxD) focuses on how a user interacts with a product over time. This course teaches you to design the 'conversation' between user and system. You will learn to map complex User Flows, define system States (Empty, Loading, Error, Ideal), and ensure Affordances make elements look clickable. We explore Fitts's Law and Hick's Law to optimize usability. This is the logic layer that makes beautiful UI actually usable.
