Interaction design (ID) is the process of determining how a user will use, or interact with, a digital product. The goal of interaction design is to create products that enable the user to achieve their objective in the best way possible.
An interaction designer will create a structural outline of the digital product. This structural outline is called a wireframe. A wireframe only contains the layout of the content and possible interactions. It doesn’t contain any visual design; this will be added later in the design process.
