Real-world oriented entertainment applications

Future network (hereafter universal network) serves as a software infrastructure for ubiquitous computing applications where diverse components such as sensors, small devices, computers, services, information, and people are dynamically integrated to provide applications. Applications on universal network merge real and virtual-worlds using various sensors and actuators. With this, we believe that new types of entertainment applications that can interact with and influence on mental or emotional parts of humans become one of killer applications. In universal network, applications are required to be adaptive to the dynamically changing situation of users' computing environments or service context so that applications can tune their components to best support users. A software infrastructure for universal network should support such adaptable and composable applications. Examples of key applications are spontaneous community, ubiquitous monster and fashion & communication. As a platform for adaptable and composable application featuring service emergence capability, an adaptive networking service architecture called Ja-Net is investigated. Applications designed using Ja-Net can adapt themselves to dynamic changes in network environments and user preferences.
