Interaction Design 1.1.1.

1.1.1. Interaction Design is the design of any interactive experience.

In today's world, Interaction Design is concerned with the creation
of meaningful experiences between us (humans) and objects. It is a
good way to explore the creation of beautiful—and maybe even
controversial—experiences between us and technology. Interaction
Design encourages design through an iterative process based on
prototypes of ever-increasing fidelity. This approach—also part of
some types of "conventional" design—can be extended to include
prototyping with technology; in particular, prototyping with
electronics.
