This book constitutes the refereed proceedings of the 7th International Symposium on End-User Development, IS-EUD 2017, held in Hatfield, UK, in July 2019. The 9 full papers and 8 short papers presented were carefully reviewed and selected from 35 submissions. The papers discuss progress in research around end-user development through, or towards, methods, socio-technical environments, intelligent agents, as well as the most effective end-user programming paradigms for smart environments. Papers and submissions in all categories addressed this specific theme together with topics that have been traditionally covered by the broader themes of end-user development, such as domain specific tools, spreadsheets, educational applications, and end user aspects.

This provides an in-depth look at the new OpenGL ES (The Standard for Embedded Accelerated 3D Graphics) and shows what these new embedded systems graphics libraries can provide for 3D graphics and games developers. It teaches fundamental 3D mobile graphics programming with standard APIs and covers the basic and advanced application program interfaces behind the major wireless and mobile devices supporting 3D graphics applications.

This book contains a series of revised papers selected from 7 workshops organized by 18th IFIP TC 13 International Conference on Human-Computer Interaction, INTERACT 2021, which was held in September 2021 in Bari, Italy. The 15 papers included in this volume were carefully reviewed and selected from 30 submissions. They show the design of interactive technologies addressing one or more United Nations' Sustainable Development Goals, to deal with evolving contexts of use in today's and future application domains and its influence on human-centered socio-technical system design and devel-opment practice, share educational resources and approaches to support the process of teaching and learning HCI Engineering (HCI-E), share educational resources and approaches to support the process of teaching and learning HCI Engineering (HCI-E), and address and discuss geopolitical issues in Human-Computer Interaction as a field of knowledge and practice.
