Abstract:

The medium is an integral part of the message when writing for interactive delivery systems. Interactive media requires attention to details on several dimensions for communication of the content. Writers must focus not only on words and meaning, but also on how the content is presented. We can look to other disciplines for models of how they document the translation of ideas into reality. The detailed design document or storyboard is the essential tool for describing multimedia content in all four dimensions.
