user experience

Definition

ISO

The International Standards Organization defines User Experience in its norm ISO 9241-210:

User experience is the user’s perceptions and responses that result from the use and/or anticipated use of a system, product or service.

Users’ perceptions and responses include the users’ emotions, beliefs, preferences, perceptions, comfort, behaviours, and accomplishments that occur before, during and after use.

User experience is a consequence of brand image, presentation, functionality, system performance, interactive behaviour and assistive capabilities of the interactive system, the user's internal and physical state resulting from prior experiences, attitudes, skills and personality, and the context of use.

Usability, when interpreted from the perspective of the users' personal goals, can include the kind of perceptual and emotional aspects typically associated with user experience. Usability criteria can be used to assess aspects of user experience.

  • The idea here was to go beyond the interaction between a user and a computer screen, to consider the broader contextual factors that are likely to have an impact on the human-computer interaction.
