1. Multimedia, Web Authoring and More

2. Overview Advanced applications –Multimedia –Web authoring –Graphics programs –Virtual reality –Artificial intelligence –Project managers

3. Multimedia Multimedia integrates all kinds of information. Pages are linked by buttons. Story boards show logic, flow and structure. Authoring programs create presentations.

4. Multimedia Also called hypermedia Integration of a variety of media such as video, music, voice, graphics and text User participation, or interactivity, is an essential and unique capability Branching out from an entertainment vehicle into business, education and the home

5. Multimedia Links and buttons - presentation usually a series of linked pages Buttons - for navigating from one page to another

6. Storyboards Used in project preplanning Record logic, flow and structure Specify content, style, design and links

7. Multimedia Authoring Programs Macromedia Director Authorware Toolbook

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

9. 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

10. HTML Code

11. Common Web Page Editors Microsoft FrontPage Adobe PageMill Corel WebSite Builder

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

13. 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

14. 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

15. Illustration Programs Modify vector images Images are collections of various objects, such as lines, rectangles and ovals

16. 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

17. 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

18. 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.

19. Virtual Reality The simulation of alternate physical realities and experiences Special interactive sensory equipment (such as headgear and gloves) Specially written software

20. 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

21. Virtual Reality Applications –Numerous and will grow exponentially over time –Viewing molecular structure –Flight simulators –Surgical training –Spaceship repair –Nuclear disaster cleanup

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

23. 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

24. 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

25. Knowledge-Based (Expert) Systems Some areas of use –Medicine –Geology –Chemistry –Military science –Photography

26. Knowledge-Based (Expert) Systems Some examples –Oil Spill Advisor –Bird Species Identification –Midwives Assistant –Grain Marketing Advisor –Senex

27. Robotics Robots –Computer controlled machines mimicking human motor activity –Reprogrammable for numerous tasks –Often used for dangerous, repetitive tasks

28. Robotics Three types –Industrial - assembly line factory work, e.g. painting, polishing, cutting, welding –Perception systems - use video cameras or pressure sensors to inspect, sort or place parts –Mobile robots - transport supplies, equipment and mail

29. Project Management Project management software allows you to plan projects, schedule people and control resources.

30. Project Management Project - one-time operation with multiple tasks to be completed within a certain time period Project Managers –Plan, schedule and control people, resources and costs –Display beginning and ending task dates –Important tools - Gantt and PERT charts

31. Project Management Gantt charts –Use bars and lines –Have two parts Table listing information about tasks Bar chart displaying durations and start and stop dates

32. Project Management PERT charts –Program Evaluation Review Technique –Represent projects with boxes and lines –Displays timing and relationships among tasks –Shows critical path - sequence of tasks that take the longest to complete
