Building a behavior model for the Ubiquitous Display to be used in a large-scale public facility

Abstract

In this paper, we built a behavior model for the Ubiquitous Display (UD) to provide a situation oriented service to the users in a large-scale public facility. The UD is a mobile-projection robot to support the user with visual information. If the UD provides a service in a public facility, we should assume the possible situations previously. According to the situation, the model should be built in consideration of its purpose. Thus, we clarify the UD's actions and define the sequences of behavior while the UD provides a service in a shopping mall, which is a sort of the large public facility. Moreover, we developed a computer simulation software in order to verify the validity of the proposed model.
