Social and physical interactions are new paradigms that outline the vision of the next generation of entertainment. We can provide these interactions through employment of technologies such as mixed reality to merge the human physical world with the virtual game world. However, there are a few obstacles in achieving physical, mobile, tangible and social interaction for people's entertainment. The authors had organized a workshop on this topic of "Mixed Reality Entertainment and Art" at the ISMAR 2007 conference in Nara, and the presentations are summarized in this paper. Furthermore, the authors detail their related systems, including BlogWall, MediaMe, and Shared Design Space to provide artistic and entertainment mixed reality.
