  13. A Multimedia Presentation Multimedia presentation Computing Essentials 1999 - 2000 Chapter 8

  14. Web Authoring Creating Web sites is called Web authoring. Graphical maps present overall site design. Web authoring programs support design and HTML coding.

  15. Web Site Design • Determining overall content to be communicated • Overall theme broken into component parts • Site design often graphically depicted, with lines indicating links • Incorporating various multimedia elements Computing Essentials 1999 - 2000 Chapter 8

  16. HTML Code HTML Code Computing Essentials 1999 - 2000 Chapter 8

  17. Common Web Page Editors • Microsoft FrontPage • Adobe PageMill • Corel WebSite Builder Computing Essentials 1999 - 2000 Chapter 8

  18. Microsoft FrontPage Web page Graphical site map Computing Essentials 1999 - 2000 Chapter 8

  19. Graphics Programs Desktop publishers mix text and graphics. Image editors modify bitmap image files. Illustrators modify vector files. Graphics suites bundle separate programs.

  20. Desktop Publishing • Mixing text and graphics to create professional quality publications • Unlike word processors, focus is on page design and layout • Popular programs • Adobe Framemaker • Adobe Pagemaker • Corel Ventura • QuarkXPresss Computing Essentials 1999 - 2000 Chapter 8

  21. Page produced by Desktop Publishing Software Computing Essentials 1999 - 2000 Chapter 8

  22. Desktop Publishing Layout Computing Essentials 1999 - 2000 Chapter 8

  23. Image Editors • Create and modify bitmap image files • Bitmap images are composed of thousands of colored dots or pixels • Artists use this programs to correct or change colors, or to add special effects • Popular programs • Adobe Photoshop • Corel Photo • Macromedia xRes Computing Essentials 1999 - 2000 Chapter 8

  24. Illustration Programs • Modify vector images • Images are collections of various objects, such as lines, rectangles and ovals Computing Essentials 1999 - 2000 Chapter 8

  25. Illustration Programs • Used by • Artists for creating line art • Engineers to create 3-D models • Popular programs include Adobe Illustrator, CorelDraw, Macromedia Freehand, Micrografx Designer Computing Essentials 1999 - 2000 Chapter 8

  26. Graphics Suites • Bundling of separate but complementary graphics programs from a vendor • Cost savings over pricing for separately purchased packages • Popular suites • CorelDraw • Corel’s Graphics Pack • Micrografx’s ABC Graphics Suite Computing Essentials 1999 - 2000 Chapter 8

  27. Virtual Reality Virtual reality creates simulated environments. VRML is a programming language to produce virtual reality applications. Virtual reality authoring programs are used to create applications.

  28. Virtual Reality • The simulation of alternate physical realities and experiences • Special interactive sensory equipment (such as headgear and gloves) • Specially written software Computing Essentials 1999 - 2000 Chapter 8

  29. Virtual Reality • VRML • Virtual reality programming language • Used to create 3-D animated scenes • Viewed with VRML capable browsers • Virtual Reality Authoring Programs • Have migrated from high-cost versions on workstations to affordable PC - based packages • Popular editions - Cosmo Worlds, Platinum VRCreator and V-Realm Builder Computing Essentials 1999 - 2000 Chapter 8

  30. Virtual Reality • Applications • Numerous and will grow exponentially over time • Viewing molecular structure • Flight simulators • Surgical training • Spaceship repair • Nuclear disaster cleanup Computing Essentials 1999 - 2000 Chapter 8

  31. Artificial Intelligence Artificial intelligence attempts to simulate human thought processes and actions. Two areas are robotics and knowledge-based (expert) systems.

  32. Artificial Intelligence • Computers’ traditional strength is in structured problem solving, humans, unstructured • Attempts to mimic human thought processes and actions • Reasoning • Learning from past actions • Simulation of vision and touch Computing Essentials 1999 - 2000 Chapter 8

  33. Knowledge-Based (Expert) Systems • Capture the knowledge of a human expert • Provide advice to decision makers • Systems use knowledge bases, which combine facts, rules and user input • Respond to user interaction • Fuzzy logic allows users to respond in more natural, human like ways Computing Essentials 1999 - 2000 Chapter 8
