Computer-Aided Design of User Interfaces VI gathers the latest experience of experts, research teams and leading organisations involved in computer-aided design of user interactive applications. This area investigates how it is desirable and possible to support, to facilitate and to speed up the development life cycle of any interactive system: requirements engineering, early-stage design, detailed design, deelopment, deployment, evaluation, and maintenance. In particular, it stresses how the design activity could be better understood for different types of advanced interactive ubiquitous computing, and multi-device environments.
