Demo: Implementation of Information-Provision Service with Smart Phone and Field Trial in Shopping Area

To achieve the information-provision service, we adopted the social network concept (http://en.wikipedia.org/wiki/Social_network_service), which handles human relationships in networks. We have implemented the information recommendation mechanism, by which users may obtain suitable information from the system based on relationships with other users in the social network service. We believe that information used by people should be handled based on their behavior. We have developed an information-provision service based on our platform. We have been studying and developing the service coordination and provision architecture - ubiquitous service-oriented network (USON) (Takemoto et al., 2002) - for services in ubiquitous computing environments. We have developed an information-provision service using the social network service based on USON architecture. This demonstration shows the implementation of the information-provision system with the actual information which was used in the field trial.
