A Workshop on Theory at ICIDS 2009 -- Workshop on Authoring Methods and Conception in Interactive Storytelling.

The rich programme of ICIDS 2009, comprising invited talks, technical pres- tations and posters, demonstrations, and co-located post-conference workshops clearly underscores the event's status as premier international meeting in the domain. It thereby con?rms the decision taken by the Constituting Committee of the conference series to take the step forward: out of the national cocoons of its precursors, ICVS and TIDSE, and towards an itinerant platform re?ecting its global constituency. This move re?ects the desire and the will to take on the challenge to stay on the lookout, critically re?ect upon and integrate views and ideas,?ndingsandexperiences,andtopromoteinterdisciplinaryexchange,while ensuring overall coherence and maintaining a sense of direction. This is a signi?cant enterprise: The challenges sought are multifarious and must be addressed consistently at all levels. The desire to involve all research communitiesandstakeholdersmustbematchedbyacknowledgingthedi?erences in established practises and by providing suitable means of guidance and int- duction, exposition and direct interaction at the event itself and of lasting (and increasingly:living) documentation, of which the present proceedings are but an important part.
