Acknowledgments

For the development of VOLUMEZERO and VOLUMEONE, many people have contributed their talents and valuable time. I would like to express my special thanks to my colleagues Kim Junghoon, Hideki Ogino, Kentaro Hirano, Sasaki Nagi, Keiko Kinuta, Masaru Ando, Miho Ishii, Andreas Bovens, Junko Sawada, Yutaka Ohga, Maki Yamamura, and artists who willingly provided their materials for experimentation.

Development of the VOLUMEZERO (introduced as VOLUMEONE at the time of its release on May 10, 2006) was made possible by the Special Coordination Funds for Promoting Science and Technology. The Research Institute for Digital Media and Content, Keio University, has been established as a part of the Encouraging Development of Strategic Research Centers Program of the Ministry of Education, Culture, Sports, Science and Technology, Japan.
