This book is based on Japanese CREST project of “intelligent information processing systems creating co-experience knowledge and wisdom with human-machine harmonious collaboration”. This research area aims to advance research and development targeting intelligent information processing systems that create co-experience knowledge and wisdom through “balanced or harmonious collaboration” of humans and machines including AI and robotics and bring about an improvement in the quality of the intellectual activities of individuals and groups. The balanced or harmonious and symbiotic collaboration means that not only users but also human society may feel the services of machines acceptable in the human-machine collaboration. Following an introductory chapter, succeeding chapters of this book present research results on: co-experience knowledge and wisdom from collective visions; co-experience knowledge and wisdom from inter-personal implicit and/or explicit interaction; common platformfor co-experience knowledge and wisdom; knowledge for social consensus formation in SNS; knowledge for social attitude and stress; co-experience knowledge on symbol grounding with human-robot interaction; and artificial consciousness modules. This is the first of two volumes, and will provide researchers and practitioners in the related areas with an excellent opportunity to find interesting new developments and to think about the relationship between human and information technology.
