  6. Multimedia Defined A computer-based, interactive experience that incorporates text, graphics, sound, animation, video and virtual reality.

  7. Graphics Drawings and Photos Animation 2-D and 3-D, Video Multimedia Elements Sound

  8. Interactivity of Multimedia • Allows user to interact with application • Content presentation is nonlinear • User determines • What content is delivered • When it is delivered • How it is delivered • Input can be keyboard, mouse, voice and touch screens

  13. Live updates on scoreboard Program needed to receive webcast can be downloaded Live broadcast Webcasting - Includes audio and video in real time

  14. Animations • Rotating text and 3-D settings • Software • HTML • Macromedia Flash • Virtual Reality Modeling Language (VRML)

  15. HTML • HyperText Markup Language • Basic Web documents • Hyperlinks • HTML tags: <i>Hello</i>

  16. Multimedia Web Pages • Java programming language • Animations • Database searches • Applets • Need for file compression • Video/audio files very large • Modem speeds can be slow

  17. Growth in % of homes using internet in US Growth in % of homes with computers in US Growth of Multimedia Prices dropped from $2000 to $500 from 1997 to 2001

  18. Internet Usage Growth Drivers

  19. Growth of Internet Users

  20. Growth of Mobile Subscribers

  21. Growth of Multimedia • Audio and video delivered on web (RealPlayer) • CD-ROM titles decreased • 1992 = $100 • Today < $20 • Computer company marketing techniques • Next “killer application” • Adding value to an existing product (the computer)

  22. Multimedia Barriers Different types of computer systems Vary in speed, capacity and display capabilities Lack of standardization Lack of a way to deliver huge amounts of information to the desktop

  23. Using Multimedia for Education Learning by experimentation Learning by association • Learning by sound • Learning by visual stimulation

  24. Multimedia Allows Students To • “Jump” via hyperlinks • Proceed at their own pace • Focus on particular areas • Be in charge of learning experience • Have instant feedback

  25. Online Course Benefits Students can: • access it anytime from anywhere • see animations with audio and video • have virtual labs to conduct experiments

  26. Edutainment CDs

  27. Reference Titles and Multimedia • Encyclopedias • Census data • Yellow Pages • Dictionaries

  28. Entertainment Applications • Pioneers in multimedia were game developers • Emphasis has shifted from: • Pure action  Action + story-telling • Games  Entertainment • Physical  Mental

  29. Games on the Web

  30. Virtual Worlds A new field in entertainment on the Web where individuals can log on and interact with others in a virtual environment that includes chat sessions.

  31. Online Entertainment Categories Sports (Beckett Interactive Football League) Mystery (Avalon) Adventure (Webstrike) Fun (Playsite backgammon, etc.)

  32. Recreation Applications • Give user a vicarious experience • “play” a famous golf course • “fly” over 3-D cityscapes • Could include hobbies and sports titles

  33. Microsoft Flight Simulator • Award winning; most popular; oldest • U.S. Navy has used it to train pilots • Requires a fairly powerful computer configuration for latest version • Has spawned web sites, user groups, newsletters, and add-on products

  34. Multimedia Category Crossovers

  35. Marketing Training Presentations Business Applications Multimedia used for communication:

  36. Marketing on the Web • Go global on the Net • Shop online • Demonstrate product lines • Allow users to customize products online • Publish magazines online

  37. Corporate Training • Multibillion-dollar industry • Focus on specific skill sets • Can be on CD or the Web • Often use an Intranet • Can train for certification tests

  38. Business Presentations

  39. Development System Playback System Computer Playback Systems

  40. Hardware Issues • Minimum configuration vs. recommended configuration • Processor can determine speed • Memory types: • Temporary: Random Access Memory (RAM) • Permanent: hard drive

  41. Hardware Issues: Displays • Monitor standards: • Screen resolution • Number of colors

  42. Hardware Issues: Displays • Resolution differences 640 x 480 1024 x 768

  43. Hardware Issues: Displays • Video Graphics Card • Video Graphics Array (VGA) • Super VGA (SVGA) • Card determines: • Resolution • Memory capacity • Number of colors displayed

  44. Hardware Issues: Sound • Need: • Audio card (Sound Blaster) • Speakers • Sound quality depends on number of bits used • Standard is 16-bit sound

  45. Hardware Issues: Digital Disks • Compact Disc Read-Only Memory • Digital Versatile or Video Disk • Drive determines • What type of disk can be played • Speed of locating data on disk (seek time) • Speed of transferring disk information to computer CD-ROM DVD

  46. Multimedia Development Systems • Speakers • Video camera • Flatbed scanner • Microphone • High capacity removable disk storage • Disk array for video capture and storage • CD-ROM recorder

  47. Development Platforms • Macintosh • Superior handling of graphics • Cross-platform capabilities • Used extensively in multimedia development • Windows • Software allows • Development on particular platform • Playback on both platforms

  48. Development Configurations • Pentium III 750 processor or Power Mac 500 • 256 MB of RAM desired • 20 GB of hard disk space • Video capture card (internal) and video source (camera, VCR, TV) • 19” monitor

  49. Digital Cameras • Menu Options: • Preview • Play back • Delete • View in slide-show • Images stored on 4 GB SDHC memory card (available upto 32 GB)

  50. Issue: What is the appropriate use of multimedia? • Does development time outweigh cost of alternatives? • How should we use text and video? • Who is your audience? • Is use of bells and whistles appropriate? • What are our objectives?
