We toss around the term “user experience” (UX) a lot, mostly as a shorthand for something like “where industrial design meets interface design.” But to be perfectly honest, that tendency does this branch of design very little justice.
The Disciplines of User Experience Design is a mega Venn diagram by Dan Saffer (given a pretty makeover by Thomas Gläser) that explores all of the overlap between UX and other fields of design. You’ll see UX’s overlap with architecture, human factors, sound design, and computer science—and you’ll also see its sweet spot, interaction design, with user interface and all of its tentacles at its heart.
To be fair, it’s impossible to present a thesis on design like this without inviting the Internet masses to scrutinize its organization. This mega graphic attempts to tackle the relationship between UX and all other aspects of design.
