“The word experience has gained significant traction over the past 15 years. Beginning with the mainstreaming of the term user experience in the software industry and, later, extended to the work of marketing professionals who began thinking about marketing as being experiential, the idea of experience as a focused professional area of endeavor is alive, well, and growing rapidly. However, the more our space grows, the more confused and chaotic is our collective understanding of the meaning of these terms. To try to help clarify this murkiness, I want to share my definitional model for the fields of experience and provide guidelines for the use of various terms.” (Dirk Knemeyer – UXmatters)
