First of all, we appreciate the hard work of all the authors who contributed to ICEC 2005 by submitting their papers. ICEC 2005 attracted 95 technical paper submissions, 8 poster submissions and 7 demo submissions, in total 110. This number is nearly equal to ICEC 2004. Based on a thorough review and selection process carried out by 76 international experts from academia and industry as members of the senior and international program committees, a high-quality program was compiled. The program committee consisted of experts from all over the world: 1 from Austria, 3 from Bulgaria, 2 from Canada, 4 from China, 1 from Finland, 4 from France, 10 from Germany, 1 from Greece, 1 from Ireland, 1 from Israel, 1 from Italy, 26 from Japan, 1 from Korea, 4 from The Netherlands, 1 from New Zealand, 1 from Norway, 1 from Singapore, 1 from Thailand, 4 from the UK, and 8 from the USA. In this number, reviewers are included. The final decision was made at the senior program committee meeting based on three reviewers' feedback, available online via the conference management tool. Through earnest and fair discussion at the meeting, 25 technical papers were accepted as long papers and 32 technical papers were accepted as short papers from 95 submitted technical papers. Moreover, 3 poster papers and 5 demo papers were accepted.

This book constitutes the refereed proceedings of the 15th International Conference on Virtual Reality and Augmented Reality, EuroVR 2018, held in London, UK, in October 2018. The 9 full papers and 6 short papers presented were carefully reviewed and selected from 39 submissions. The papers are organized in 5topical sections: vision-based motion tracking; 3D acquisition and 3D reconstruction; haptics and 3D audio; perception and cognition; interactive techniques and use-case studies.

This book is an outcome of the symposium "Towards Earth Friendly Use of Resources and Energy," organized by the Nagoya University Center of Excellence Program "From Earth System Science to Basic and Clinical Environmental Studies" and presents papers by four eminent researchers. 1) Syukuro Manabe, who was honored in 2008 by the Earth Hall of Fame Kyoto, together with Ms. Maathai and Ms. Brundtland, describes the mechanisms of extreme weather, drought, and flood that were caused by climate change due to CO2 emissions. 2) Ernst Ulrich von Weizsacker, co-chair of the Club of Rome, describes "Factor 4 and 5" concepts such as technological progress and redesigning socioeconomic systems, e.g. taxation, and stresses the importance of humanity. 3) Hans-Peter Durr, ex-president of the Max Planck Physics Institute as a successor of Heisenberg, explains the mechanism of a living Earth sustained by accumulated energy resources provided by the sun. He clarifies a point on preserving the dynamic stability of minerals and life on Earth. 4) Shohei Yonemoto, a well-known political scientist focusing on sustainability, explains environmental politics and why the IPCC and UNFCCC framework were established based on precaution principles. He puts forward a new concept called futurology, which considers population and food problems from a Malthusian standpoint and incorporates them into issues such as climate change and natural disasters. This book is written and based on a very simple but concrete idea and provides the readers with a chance to consider the shape of future Earth.
