One can go to the web and try to find a definition for User-Experience Design. They’ll find results such as this:

User experience (UX) is about how a person feels about using a product, system or service. User experience highlights the experiential, affective, meaningful and valuable aspects of human-computer interaction and product ownership, but it also includes a person’s perceptions of the practical aspects such as utility, ease of use and efficiency of the system. User experience is subjective in nature, because it is about an individual’s feelings and thoughts about the system. User experience is dynamic, because it changes over time as the circumstances change.

But sometimes, animations can do more. Here’s a couple by lyle on Vimeo.
