User experience

Definition

The overall experience and satisfaction a person has when interacting with a product, service, or system, encompassing usability, accessibility, and emotional response.

Etymology

Coined by cognitive scientist Don Norman at Apple in the 1990s to describe a holistic approach to design beyond just usability. Built on earlier human factors engineering and ergonomics research from the mid-20th century, but expanded to include emotional and aesthetic dimensions.

Kelly Says

User experience design recognizes that people make decisions emotionally first and rationalize them logically afterward, which is why successful products often prioritize how they make users feel over pure functionality. The field has expanded beyond digital products to encompass service design and even architectural spaces.
