During the first Interaction Design Foundation Milan Chapter event, the group decided to define the most important interaction design related terms.
I started to approach professionally this field of Digital Communication a few months ago, but I care about User Experience since my first project in 2006.
My definitions are really general, almost philosophical. They are based on my daylife experience and on what I’m learning at Interaction Design Foundation courses.
UX is how users use and feel a digital product.
UI is what users see and use for interacting with a digital product.
IA is how contents and functions are titled and positioned in a digital product’s plain structure.
Usability is a digital product use efficiency rate.
Interaction Design is designing UX and IA and contributing to the UI.
Service Design is everything involves customers beyond the strictly digital product experience.
I hope you enjoy.
If you don’t, I agree with you. This is a User Experience feedback too 😉
