This book constitutes the refereed proceedings of the 9th International Conference on Intelligent Technologies for Interactive Entertainment, INTETAIN 2017, held in Funchal, Portugal, in June 2017. The 15 full papers were selected from 19 submissions and present developments and insights in art, design, science and engineering regarding novel entertainment-focused devices, paradigms, and reconfiguration of entertainment experiences.

In thispa per, we describe the key lessons from an earlier HCI Educators' conference, held in Limerick in 2006, on 'inventivity' - a term coined to highlight the confluence of inventiveness and creativ ity. There is a distinction between being creative andbein g artistic. HCI education, in terms of creative inventiveness, is not just about artistically pleasing user inte rfaces, but also about solutions that are innovative. We can know much about creativ ity and inventiveness. However, tobe able to teach and train students so that th ey can be creatively inventive, we believe that it would be helpful if educators themselves have personally experienced this. With this in mind, we organised the follow up conference HCIEd 2007 Creativity: Experiencing to Educate and Design. Inventivity was coined to refer to the notiono f inventing creative and innovative solutions. This term was also intended tomean that such solutionsb e more than 'creative', artistic or appealing interfaces as designed by artistic or 'creative types' of people. It was also intended to reflect the creativeness of the solutions that had to be invented. One reason for emphasising this as pect at the conference was that, in HCI design it is easy to mis interpret the focus ofHCI d esign solutions - which should notad dress just visualisation and interaction design, but also address how that visualisation and interactioncreativ ely repr esents and simplifies the complexities in work thatpe ople engage in.

This book describes the BadIdeas method, a tool that aims to nurture creativity and innovation during the design and development of novel user interfaces. The BadIdeas method initially focuses on the generation of bad ideas, which are then submitted to a critical examination. Later, these divergent ideas are transformed until they are of good use and materialise into a tangible artefact or idea for future implementation. Creativity and innovation emerge as fundamental requisites in terms of design and development of present-day user interfaces. While conventional user interfaces need to ensure usability, in addition, less conventional ones require creativity and innovation in order to create engaging and pleasurable experience. In order to nurture these elements throughout the process of design and development of novel user interfaces, the author proposes the use of the BadIdeas method. A review of literature on Human-Computer Interaction, Design and Creativity sets the scene for this work, which then focuses on communicating the iterative development of the BadIdeas method, ultimately forming the major contribution of this research.
