It is not the case that a reader can only interact if she is convinced she is in her own idea space or story world. Its choices proceed from the expression of possibilities as a narrative medium and depend upon the complicity of the reader in the creation of a narrative. Reading is design enacted. Apprehension of character is participatory design. It is, in this sense, design determined.
Authorship is an invitation to active design.
Hypertext narratives become virtual storytellers and narrative is no longer disseminated irreversibly from singer to listener or writer to reader. However, even in a system which generates narrative, interaction is the assumption of authority over the replacement of one writing by another. Thus the human side of the cycle demands primary attention. To do so, the primacy of the text must be marginalized. The reader declares independence from the software agent and the contingent structure of the virtual reality alike.
