Complexity is everywhere around us and technological advancements are changing almost every aspect of our lives. The quality of the interface between a system and its user determines the system's value, whether it be a product, a piece of technology, a specific service, the environment we live in, or some piece of information.

User experience and usability are the key factors in reducing complexity. Usage orientation has to be taken into account explicitly and seriously. Introducing the user into development processes from the very beginning will have an immediate and sustained impact on quality and innovation.

The utilization of knowledge from the field of User Experience Research is of immediate economic, social and cultural significance. It pays off to make the user a priority through user experience research and usability engineering. User Experience is the crucial link between technological advancements, application fields, usage needs, and economic interests.
