INTERACTION APPROACH FOR DIGITAL VIDEO BASED STORYTELLING Norbert Braun Department of Digital Storytelling Computer Graphics Center (ZGDV e.V.), Rundeturmstrasse 6 64283 Darmstadt Germany Norbert.Braun@zgdv.de http://www.zgdv.de/distel ABSTRACT This paper shows an approach for a storytelling oriented interaction on digital video. All the interaction capabilities of the system are driven by the video context and therefore media centric. Interaction possibilities are given to the audience by conversation (on topics of the video content) or by classical Direct Manipulation (of video objects). Conversations can be done by the user with a personalized assistance or directly with the video. The implementation of the approach is shown by a discussion about an application architecture on the basis of Real Media Server, SMIL and Java 3D. The application runs as a Video On Demand system, accessible through the world wide web. Keywords: Interaction, Conversation, Media Centred, Digital Video, Digital Storytelling. 1. INTRODUCTION User interfaces surprise the every day user with permanently new methods of interaction on their computer systems. Operating systems please their audience with approaches like Direct Manipulation WIMP-Interfaces, drag-and-drop, conversational interfaces for delegation of tasks etc. . Anyhow - generally the interaction metaphors are built as interaction with the system - not interaction with the information that users are looking for and systems are delivering. The interaction is system- centred, but not centred on the needs of the user. If users shift from one system to the other, the interaction opportunities on these systems change too. Users have to adapt to the system’s interaction, therefore spend a lot of time learning interaction methods. This disturb the users concentration on the information they need to manage within every day work. The change to User Centred Interaction is nevertheless tricky. What is User Centred Interaction exactly?! If
