Interactive Design

Interaction design defines the structure and behaviors of interactive products and services, and user interactions with those products and services. Interaction Designers create compelling relationships between people and the interactive systems they use, from computers to mobile devices to appliances. Good interaction design effectively communicates a system’s interactivity and functionality, defines behaviors that communicate a system’s responses to user interactions, reveals both simple and complex workflows, informs users about system state changes, and prevents user error.
Interaction design is grounded in an understanding of real users (goals, tasks, experiences, needs, and wants) and balances these needs with business goals and technological capabilities.
