In design, human–computer interaction, and software development, interaction design, often abbreviated IxD, is "about shaping digital things for people’s use", alternately defined as "the practice of designing interactive digital products, environments, systems, and services." Like many other design fields interaction design also has an interest in form but its main focus is on behavior. What clearly marks interaction design as a design field as opposed to a science or engineering field is that it is synthesis and imagining things as they might be, more so than focusing on how things are.
Interaction design is heavily focused on satisfying the needs and desires of the people who will use the product. Where other disciplines like software engineering have a heavy focus on designing for technical stakeholders of a project.

Famous quotes containing the words interaction and/or design:
“Just because multiples can turn to each other for companionship, and at times for comfort, don’t be fooled into thinking you’re not still vital to them. Don’t let or make multiples be parents as well as siblings to each other. . . . Parent interaction with infants and young children has everything to do with how those children develop on every level, including how they develop their identities.”
—Pamela Patrick Novotny (20th century)
“Delay always breeds danger; and to protract a great design is often to ruin it.”
—Miguel De Cervantes (1547–1616)
