Objects exist in a hierarchical order of parent and child relationshipsrelationships. Each object is assigned properties and modifiers. On receiving messages, objects perform tasks depending on the properties and modifiersproperties and modifiers.

Multimedia Multimedia Authoring Metaphors: Authoring is the process of creating Multimedia applications. Most Authoring programs use one of several Authoring metaphors, also known as Authoring common Authoring metaphors are:a. Scripting Language metaphor: The idea here is to use a special language to enable interactivity and allow conditional, jumps, loopsfunctionsmacrosegopenscriptlanguage loops, functions, macros open script language b.

9 Slide Show metaphor: Slide shows are by default a linear presentation. Although Tools exist to perform jumps in slide shows, very few practitioners use them. Power Point, Image Q. 20c. Hierarchical Metaphor: Here user controllable pelements are organized into a tree structure. Such a metaphor is often used in menu driven Iconic/Flow control metaphor: Graphical icons are /ppavailable in toolbox, and Authoring proceeds a flowchart with icons Authorware by other types Metaphor2. Card/Scripting Cast/Score Scripting Multimedia Production: A Multimedia project can involve a host of people with specialized skills.

10 Multimedia production can easily involve an art director, graphics designer, production artist, user interface designer, sound designer, 2D and 3D final part is the design phase which includes prototyping and testing. Some Multimedia designers use an Authoring tool. User testing is off course extremely important before the final development Multimedia Presentation: This section includes some effects to keep in mind for presenting Multimedia Graphics Style: Many presentations are meant for business displaysratherthanappearingonthescreenHu manvisualdisplays, rather than appearing on the screen. Human visual dynamics are considered in regard to how such presentations must be Color principles and Guidelines: Some color schemes and art styles are best combined with a certain theme or style.
