Nova ISO 13407 define Experiência do Usuário

"In the revised standard we define it as ‘all aspects of the user’s experience when interacting with the product, service, environment or facility’ and we point out that ‘it is a consequence of the presentation, functionality, system performance, interactive behaviour, and assistive capabilities of the interactive system. It includes all aspects of usability and desirability of a product, system or service from the user’s perspective’."
