Strategies
Crawford discusses three potential strategies for developing interactive storytelling systems. Firstly, environmental approaches are those which take an interactive system, such as a computer game, and encourage the actions of a user in such a way as to form a coherent plot. With a sufficiently complex systems emergent behavior may form story-like behavior regardless of the users actions.
Secondly, data-driven strategies have a library of "story components" which are sufficiently general that they can be combined smoothly in response to a user's actions (or lack thereof). This approach has the advantage of being more general that the directed environmental approach, at the cost of a much larger initial investment.
Finally, language-based approaches require that the user and system share some, very limited, domain-specific language so that they can react to each other and the system can 'understand' a greater proportion of the users actions, Crawford suggests approaches that only use, for example, pictorial languages or restricted versions of English.
From the background of a multimedia author, media director and designer Eku Wand describes further strategies which are related to structure, space, time and perspective.

Famous quotes containing the word strategies:
“By intervening in the Vietnamese struggle the United States was attempting to fit its global strategies into a world of hillocks and hamlets, to reduce its majestic concerns for the containment of communism and the security of the Free World to a dimension where governments rose and fell as a result of arguments between two colonels’ wives.”
—Frances Fitzgerald (b. 1940)
