Interaction Design

As a central discipline within Human-Computer Interaction (HCI), Interaction Design (IxD) focuses on structuring and shaping the behavior of interactive digital products and services. It defines the "dialogue" between a user and a system, orchestrating the flow, controls, and feedback that allow a person to achieve their goals. Grounded in the technical possibilities and constraints defined by computer science, IxD aims to create experiences that are not just functional but also intuitive, efficient, and enjoyable, carefully crafting every point of contact between the human and the machine.
