• 論文の詳細を見る

• We consider delivering interactive dramas. A viewer interacts with a contents provider by answering multiple-choice questions and the answers to these questions influence the plot of delivered story. All possible plots can be represented by a directed graph such that every plot corresponds to some path of the graph. A delivery should be controlled according to the directed graph such that each viewer's history of answered choices forms a path of the graph. On the other hand, because some character of a viewer is known to a contents provider from his history of choices, a viewer tries to prevent even a contents provider from linking choices made by him. In this paper, we introduce unlinkable delivery for an interactive drama and propose such a delivery system for interactive dramas that viewer's choices are unlinkable and delivery is controlled according to the directed graph.
