Abstract: A rich interactive narrative (RIN) authoring system and method for creating and generating RIN documents in a graphical and visual manner. RIN documents are documents that contain multimedia content and combine narrative with interactive exploration. Embodiments of the RIN authoring system and method facilitate the creation of RIN documents without the need for the author to program or write code. Embodiments of the system and method provide a user interface for an author to select an experience stream, and place the experience stream on a timeline to indicate a desired location in time when the experience stream should appear in the RIN document. The author can define keyframes in the experience stream and edit those keyframes to define a trajectory between multiple keyframes in the RIN document. Embodiments of the system and method also allow the preview the RIN document in a preview window.
