From User-Centred Design to Human-Centred Design and the User Experience.

The chapter describes the evolution of the User-Centred approach, from the theoretical and methodological body aimed at understanding and interpreting the needs of users in the use of the product/system, to the Human-Centred approach aimed at assessment and interpretation of the overall quality of the interaction between people and the products/systems with which they relate. It also dealt with the User Experience approach, the definition of which has spread in recent years in many different contexts and disciplines; However, this rapid adoption was not accompanied by a precise definition of the concept, which is therefore attributed to partially different meanings, all of which share an ambition to overcome the concept of usability and to study the experience systems-services. In particular, strategies considered most significant for the evaluation of perceptual and emotional experience in the use of products-systems-services are addressed. And how these aspects are strategic within the Human-Centred Design approach.
