Figure 12.6: Bar chart representation of the first-cut presentation script after media selection. Information types are placed on the y axis with the task subgoals that determine the script order on the x axis with media resources represented by bars. For this browsing task, three separate sequences are planned for the view schedule, promotions, etc.

The duration of media presentation is cross referenced to the task sequence, and the key information items to be made salient are specified.
