Interaction design is the methodical form of design concerning user experience with a certain creation. Whether that’s a physical or digital item, the personalized needs of the user are addressed in varying forms. The greatest challenges seem to be the complexities throughout the process of designing a proper user interface with the user in mind. There are many variables that dabble in a multitude of studies and mediums, and it is understood that each artist of interaction design is essentially working through a thick shadow of vagueness and points that haven’t been articulated properly.
Interaction design is particularly growing in the direction of post-modern media that functions through types of computers. It draws from the fields of graphic design, psychology, anthropology, marketing, data analytics, ethnography, engineering, and now, website development, as well as other forms of computer software and hardware design and engineering. Its evolution seems to have grown into something increasingly technological, as well as increasingly oriented around products rather than devices or items on their own. There is a significant focus toward marketing language present in the text that illustrates this plainly to me.
