Abstract


The objective of this study is to develop ¡ÇVirtual Collaborator¡Ç as a new type of human-machine interface, which works as ¡Çintelligent interface agent¡Ç to help machine operators controlling large scale machine system such as power plants. In this paper, first, triple dynamics as the design framework of the virtual collaborator is explained, which is the integration of layered module structure and the two scientific frames of brain science and cognitive science. At the present status, a prototype system of the virtual collaborator has been under development, where the prototype system has been successfully constructed based on the triple dynamics. Major functions of the present virtual collaborator are that when an anomaly occurs in a virtual nuclear power plant, the virtual collaborator can autonomously detect it, diagnose the root cause, and operate the control panel in accordance with emergency operation procedures, although it has no bi-directional communication functions. In order to realize bi-directional communication as the next stage development, the relationship between human and the virtual collaborator, and the method of utilizing voice communication are discussed in this paper.
