Lately, automatic content generation has been receiving increasing attention, and studies pertaining to narrative generation systems have great scope of application in this field. A fundamental issue in designing applications of narrative generation technology is developing a connection between a narrative generation program and people. In this paper, we propose a visual interface for providing various computer-generated narratives to the user. The narrative generation program was also developed by us previously. The interface is used to arrange and visualize narratives into a two-dimensional space on the basis of their structural features. Users will be able to explore and browse narratives by using the visualized objects based on their own values or objectives. We have shown several visualization examples to help in discussing the availability of the interface. In addition, we have presented a new line of research, brought to light by this proposal—the vision of a co-creative connection between narrative generation systems and people, in particular.
