1 Oman College of Management and Technology Course MM Multimedia Authoring Programs CS/MIS Department

2 Multimedia Authoring Programs Create multimedia titles Produce content w/paint, text & animation tools Design screen layout Create interactivity Incorporate text, sound, video, animation & graphics Create hyperlinks

3 Multimedia Uses Multimedia Presentations One-way, linear communication process Similar to slide show Stand-Alone Applications One-on-one situations User control view & review selections hyper linking

4 How Authoring Systems Work? Metaphor Used Electronic Slide Shows Card Stack and Book Metaphor Icon-based Authoring Programs Time-based Authoring Programs

5 Electronic Slide Show Metaphor Show slides one at a time Similar to overhead transparencies or 35mm slides Intuitive (simple) systems Can include multimedia elements and hyper-linking Example: Microsoft PowerPoint Advantages Easy to learn & use Inexpensive Provide templates Cross-platform capability Can play on systems without the software

6 Electronic Slide Show Metaphor Disadvantages Linear Non-interactive nature Not attractive for interactive titles Delivery Self-running (through kiosk) Distributed on CD to users Played from Internet Can supplement Web-based lectures

7 Microsoft PowerPoint Terms Presentation Slide Objects Development environment

8 Microsoft PowerPoint Features Design templates Auto layouts Autoshapes Customization Animation Multimedia Views: normal, outline, sorter, slide show

9 Card Stack and Book Metaphor Card/page-based authoring metaphors and authoring systems organize elements as pages of a book or a stack of cards (Kenez, 1995). The method is best used when the multimedia content consists of elements that should be viewed individually. A card/paged-based authoring system links the pages or cards into organized sequences and is well suited for hypertext applications. The card/page-based authoring metaphor would be an effective means of presenting and organizing the "points of interest" section.

10 Card Stack and Book Metaphor Examples: HyperCard linked cards ToolBook each page is a screen Apple - HyperCard, Allegiant - Supercard, Microsoft - FrontPage, and Asymetrix - Multimedia Toolbook. Advantages Easy to understand metaphor 1 screen = 1 card = 1 page Easy to use Provide template Short development time Disadvantages Some run only on one platform Tools not as powerful as equiv. stand-alones

11 Hypercard Authoring Program Developed in 1987 on Apple computers Develop cards with different elements associated with them Put cards in stacks Link the cards with buttons to jump to a different card HyperStudio is a more recent version

12 Toolbook Authoring Program Based on a book metaphor Author level creates the title Reader level interacts with the program Developed by Asymetrix Easy to use

13 Toolbook Terms Book Page Object Properties

14 Toolbook Features Template Animation editor Media Player Coach Catalog OpenScript Distribution

15 Icon-based Authoring Programs The icon/flow-based authoring metaphor provides the multimedia developer with a visual programming technique for sequencing multimedia events (Lopuck, 1996). The icons used represent graphics, audio files, animations, and text. Icon-based authoring systems provide the fastest development method. They are best suited for rapid prototyping and rush projects. The icon palette is the core of the paradigm. An icon/flow-based authoring metaphor and development tool such as Authorware would be an excellent choice to develop a prototype

16 Icon-based Authoring Programs Authorware uses symbols in a flowchart scheme Example: Macromedia - Authorware, Aimtech - IconAuthor, and HSC - InterActive. Advantages Easy to see structure, flow and branching Easy to edit and update Disadvantages Less intuitive Difficult to learn

17 Macromedia Authorware Terms Application Design Window Presentation window Flowchart Flowline Icons Knowledge objects

18 Macromedia Authorware Features Drag and drop Text and graphics editing Text search and spell check Knowledge Object wizard Path animation Data tracking Packaging Web packager

19 Time-based Authoring Programs Uses a movie metaphor Plays movie until an action causes it to stop or pause Allows branching to another part of movie User has control The time-based authoring metaphor and Director 8 would be appropriate to use for the introduction and conclusion.

20 Time-based Authoring Programs Macromedia Director - movie metaphor Example: Macromedia - Director 8 and Adobe - Premiere. Advantages Good for creating animation Branching, user control, interactivity Disadvantages Expensive Steep learning curve for advanced features

21 Macromedia Director Terms Movie Stage Window Score Window Cast Window Cast Members Sprite Channel Frames

22 Macromedia Director Features Animation Property inspector window Paint window Cast manager Projector File format support Multi-user support Web delivery

23 Programming Languages Creates programming code C++ (most popular) Visual Basic Perl Java (Web) JavaScript (Web)

24 Programming Languages Advantages: Flexibility Lets you tailor the application Ability to run on different platforms Disadvantages: Not specifically designed to create multimedia applications More difficult and time-consuming

25 Programming Languages Examples: Toolbook to handle buttonclick Flip 4 pages end buttonclick Buttons (action to take if user clicks on it) Developer would select the correct button on the screen and create this script

26 Java Language Developed by Sun Microsystems Capability of being cross-platform Can create animations and search databases Can extend functionality of HTML with Java applets Java Applets Small programs developed for a specific purpose Can be shared with other applications, especially on the Web Downloaded to user machine from Web server Can create your own if you are an expert Custom codes available from: User groups and Free From the Web Sun Microsystems & other developers Third-party developers

27 Java Script Scripting language for Web interactivity Mouse rollovers Can interact with a Java applet JavaScript creates dialog box User enters text Java applet checks the text and modifies the font to fit on the screen Common Gateway Interface CGI is a specification for programming languages Programs run on the server Can obtain and return information to the user Example: Web searches

28 HTML Standard for creating web pages Markup (not programming) language Uses tags to mark elements Browser interprets these tags to display the web page More limited than programming languages Cannot create multimedia applications, but can incorporate these elements into web pages

29 Scripting Languages Programming languages that create scripts A script is program code for a specific task Example:

30 Authoring Programs and Scripting Authoring program creates programming code automatically Authoring program has its own scripting language for Accessing external media (CD-ROM) Creating interaction Controlling speed of animation, etc. if rollover(5) then put Roadster into field Message end if Macromedia Director s Lingo Rollover Example

31 Choosing Authoring System Based on: Target playback system Desired features Development timeline Budget Developer s expertise
