  • Marshal McLuhan in 1964. A medium itself, not the content it carries, should be the focus of study. A medium aects the society in which it plays a role not only by the content delivered over the medium, but also by the characteris@cs of the medium itself. BAMMF June 20, 2014 2 Media

  • Storytelling: The Oldest and most powerful Art. A story is a chain of events that begins at one place and ends at another. A story is a selecAve batch of informaAon. It selects details, arranges them, perhaps embellishes them. BAMMF June 20, 2014 18 h6p://janefriedman.com/2011/09/27/what-is-a-story/
  • Where do Events happen? In Real World. Images, video, audio, all other sensors are just a means to detect and capture some aspect of the event. BAMMF June 20, 2014 19
  • Events are Connectors Events create Context Event contains Information and Experiences Spatial Causal Experiential Informational Temporal Structural
  • So What is Digital Storytelling? Prepare a database of all events. Collect all experienAal and informaAonal data about each event. Considering audience and the message, select important events. Render Events For each event decide what informaAon and experienAal data should be used. Render all events and related data in the best format for highest quality of experience.
