Multimedia
Multimedia integrates all kinds of
information. Pages are linked by buttons.
Story boards show logic, flow and
structure. Authoring programs create
presentations.
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
Multimedia
• Links and buttons - presentation usually a
series of linked pages
• Buttons - for navigating from one page to
another
Storyboards
• Used in project preplanning
• Record logic, flow and structure
• Specify content, style, design and links
Multimedia Authoring Programs
• Macromedia Director
• Authorware
• Toolbook
Web Authoring
Creating Web sites is called Web
authoring. Graphical maps present
overall site design. Web authoring
programs support design and HTML
coding.
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
HTML Code
Common Web Page Editors
• Microsoft FrontPage
• Adobe PageMill
• Corel WebSite Builder
Graphics Programs
Desktop publishers mix text and graphics.
Image editors modify bitmap image files.
Illustrators modify vector files. Graphics
suites bundle separate programs.
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
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
Illustration Programs
• Modify vector images
• Images are collections of various objects,
such as lines, rectangles and ovals
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
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
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.
Virtual Reality
• The simulation of alternate physical realities
and experiences
• Special interactive sensory equipment (such as
headgear and gloves)
• Specially written software
• VRML
Virtual Reality
– 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
Virtual Reality
• Applications
– Numerous and will grow exponentially over
time
– Viewing molecular structure
– Flight simulators
– Surgical training
– Spaceship repair
– Nuclear disaster cleanup
Artificial Intelligence
Artificial intelligence attempts to simulate
human thought processes and actions. Two
areas are robotics and knowledge-based
(expert) systems.
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
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
Knowledge-Based (Expert) Systems
• Some areas of use
–

Medicine
Geology
Chemistry
Military science
Photography
Knowledge-Based (Expert) Systems
• Some examples
–

Oil Spill Advisor
Bird Species Identification
Midwives Assistant
Grain Marketing Advisor
Senex
Robotics
• Robots
– Computer controlled machines mimicking
human motor activity
– Reprogrammable for numerous tasks
– Often used for dangerous, repetitive tasks
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
Project Management
Project management software allows you to
plan projects, schedule people and control
resources.
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
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
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
