Nice one, @leighrubin =) That’ll be a useful tool for explaining interaction design and UX to the team!
Although I’d define user experience as a non-exclusive superset of three key disciplines:
- Interaction Design
- Visual design (instead of interface design?)
- Information architecture
And then have ‘interface design’ at the intersection of ‘interaction design’ and ‘visual design’.
[B]Related disciplines: [/B]UX also intersects with:
- Human computer interaction
- Human factors
- Content creation
- Industrial design
Functions: With the above disciplines we can then get particular functions by looking at their intersections with ‘interaction design’:
- Interface design: interaction design and visual design
- Spatial experience: Architecture, visual design and interaction design
- Controls: industrial design and interaction design
- usability engineering: interaction design, human computer interaction and human factors
- Navigation design: interaction design, information architecture and visual design
Methods/techniques are involved in many different disciplines. For example, user research techniques like contextual enquiries, or analytical methods like affinity diagramming, would be used by many forms of design not exclusive of interaction design, or even of user experience design.
Dan Saffer did quite a bit of thinking about these models (see http://www.kickerstudio.com/2008/12/the-disciplines-of-user-experience/) when writing his book “Designing for Interaction”.
Here’s the diagram he constructed:
