Research on human behavior supports the idea that user experiences should be as infused with emotion as they are with logic and rationale.
The essential difference between emotion and reason is that emotion leads to action while reason leads to conclusions.
User Experience (UX) refers to any interaction a user has with a product or service. UX designers carefully consider every element that shapes this experience for the end user, such as the emotional response you get from a user or how easy (or difficult) it was for them to achieve their desired tasks. UX could be anything from how a physical product feels, to how seamless the checkout process is when purchasing online. The goal with UX is to create a simple, efficient, relevant and delightful experiences for the user. To do that effectively, you need to know who your users are.
