Multimedia Production Technologies in Workforce Education

What is Multimedia?

...the term that has been coined to cover all of the synergistic uses of text, voice, music, video, graphics, and other forms of data to enhance the computer's role as a communications device (Dillon & Leonard, 1998).

...the uses of more than one medium to present information -- computer integrating text, graphics, animation , and sound...(Tway, 1992).

...sequential use of a number of media for instruction or other communication (Kemp & Smellie, 1989).

...expanded the "definition" of multimedia to include web development resources (Levine, 2003).

The growing use of technology in society has given rise to numerous efforts to incorporate it into the teaching and learning environment.  Although technology has been in use in education for years, the new developments in this area have see renewed interest in how this technology might be used more effectively in the teaching and learning process.  As teachers sought to motivate their students, technology was being used in different combinations, resulting in the use of the term multimedia.

Multimedia has been loosely referred to as different media being used merely for the purpose of instruction.  It has also been used in reference to computer software which contain different media components. Multimedia is however much more than that.  Heinich, Molenda and Russell (1989) described multimedia as the sequential or simultaneous use of a variety of media formats in a given presentation or self-study program.

Tway (1992) stated that multimedia more recently has come to mean more than the integration of text and simple graphics but encompasses sound and moving graphic images, sometimes call animation.  An important aspect of multimedia is the level of integration accomplished in working with different types of media during the process of instruction of just transmitting information. Multimedia combines among other things touch-sensitive displays, full-motion video, photographic images, animation, illustrations, high-fidelity voice recordings, sound effects and music (IBM, 1992).

Multimedia applications have their roots in standard training and education courses with or without exercises, CBT (computer-based training) programs for education and training, and video games, simulations and stories for fun and entertainment (Dillon & Leonard, 1998).

ADA (Americans with Disabilities Act) compliance is an important issue to be considered when producing applications for people with disabilities who are the end users. 

Components of Multimedia

Visual: Video, animation, photos, graphics and text

Audio: Narration, music and sound effects

Multimedia Product Applications

Multimedia publications can be used to enhance the presentation of information on many levels adding video, graphics, sound or other multimedia elements to the traditional text can hold user attention and improve the retention of information.  Multimedia projects do not have to be interactive to function effectively.  Users can connect to content and messages using only eyes and ears just as they do at the movies or watching television.  This form of presentation, which starts at the beginning and runs to the end, is called linear.  Multimedia projects with navigational controls allowing the user to move through the content at will are referred to as non-linear or interactive.  Designs and applications for linear, non-linear and combination multimedia forms will be discussed in future units.

Multimedia products have obvious application in the areas of:

Some less obvious applications include:


This lists but a few of the potential uses of multimedia products.  The rapid advance of technology continues to expand the list, bringing increased capabilities and new innovation roles for multimedia.

Dillon & Leonard (1998) give the following definition of multimedia applications:

"Though the decade of the 1990's has witnessed an explosion in what are being called multimedia titles, few have stopped to question what type of content denotes a multimedia application.  We offer the following three-part taxonomy as a tentative starting point for defining the array of multimedia applications."

Unit 2: Introduction to Quest. 
Top

This unit will provide basic knowledge of the mechanical workings of Quest 7.0.  The student will learn the Quest title structure, methods of interconnection, design and scripting of frames (pages), and file structure.  Quest C is the programming language used to enhance computer-based multimedia training.

Authorware in its earliest beginnings was a programmer's tool to create a shell in which multimedia activities take place.  Today, authorware is a programming for non-programmers.

Unit Objectives

Upon completion of this unit, students will be able to define:

Unit Information

Quest allows the developer to build projects that consist of two elements to hold content: frames and modules. 

How do you create training in Quest?

The file you create and save your training to is called a project.  It uses a .qp6 extension, which stands for Quest project using software version 6.

Frames contain a single screen of interaction.  Frames consist of several different elements, such as graphics, animation, text and so forth. Modules contain frames and are used to organize or divide your title into logical chunks or groups.  In Quest, the student arranges frames and modules in a flow chart.  The flow chart is a flexible organization of your title.  The student identifies how many modules and frames are needed; how modules and frames are connected to each other and where users can gain access to modules and frames.

The following is an example of a project in Quest.  It also identifies some other elements you can use to control the "flow" of your title. 

This part of Quest is called Title Design.

What's beyond Title Design?

Once you add a frame at the Title Design level, go into the frame and add objects.  Objects are the items your users see on the screen or that create interaction.

Some examples are:

Graphics
Rectangles, lines, ellipses
Text
Buttons
Animations

As you add objects to your frame, Quest adds them to the frame's object list. 

To control how and when you want objects to appear on the screen or action to take place, use the following.

Watch Fors - tells Quest to constantly watch for something to happen.  This "something" is called an event.  When it does happen, Quest executes the item inside of the Watch For.

For example, when users click the "Next" button, you want to go to the next screen, which is called Frame 2.  To do this, you would use the following sequence.

Wait Fors - tells Quest to wais for an event you specify before it moves on to the next item in the object list.

For example, you present a video on the screen and want to wait for the video to stop before you show a the "continue" button.  To do this, you would use the following sequence.

You can also wait for five seconds (or 5,000 milliseconds) for the end user to read text before moving on or wait for an animation to stop before showing the "Next" button.   

Branches - this command tells Quest to go to the frame you specify.

For example, the following command branches the title to "Choice" when users click the "Continue" button.

Object Services - this command tells Quest to carry out an action you specify on the object you select. Services include hiding and showing objects, enabling and disabling objects, and identifying or setting object attributes.

For example, you want to hide a "feedback panel with a button" (so users can't click it) while your background and text appears.  When the user answers the question, enable the "feedback panel with a button" so users can click it to move on.

Variables - use the declare variable tool to add a variable to your project.  Variables keep track of things that change or occur at different times in your project.  You can also type the variable directly onto your list without using the tool.

For example, declare a variable called "Count" in the M Choice frame to count the number of incorrect answers to the multiple choice question that keeps track of a user's test score.

Function Calls - perform a task over and over again with one piece of code that you store and then call when you need.  There are standard Quest C functions you can use or you can write your own directly in the object list.

for example, you use a thread module to show your navigation graphics in your project.  Suppose you don't want this to show on your main menu.

Declare a function that hides the thread when users access the main menu.

F() Function Call HideThreadWindow(Navigation);

Upon completion of the tutorial (handout), students will be able to:

Unit 3: Organizing the Multimedia Production Project
Top

This unit will show students how to formulate the scope and content of a multimedia project.  In this unit, students will learn how to analyze what skills, time, budget, tools and recourses are available for multimedia product development, how to organize their multimedia plans and ideas into a logical flowchart for developing the multimedia product.

Unit Objectives

Unit Information

Before we can begin to process, plan and produce, team roles must be established.  The team leader must decide how these roles are to be distributed.  It is suggested that on the first project, people should be put into roles according to their skills.  The leader may assign roles or agree upon roles by consensus.

The establishment of roles prior to processing is important, so that all components of the multimedia production have someone who is responsible for their production and placement.

There are six development stages in multimedia production
 

  1. Idea Processing - identifying multimedia project purpose/goals, flow charting product look, feel, structure, etc.

  2. Planning - estimating resource availability, timelines, budgets, etc.

  3. Designing - translating ideas and concepts into detailed resource development parameters

  4. Production - performing each of the tasks required to develop the multimedia product

  5. Testing - verifying that the multimedia product does what it was intended to do

  6. Delivery - getting the product to end user

Successful multimedia project organization requires advance planning on the part of the multimedia project team members.

Here are several questions to consider during the idea processing and planning stages of multimedia product development.

  1. What is the purpose of the multimedia product?
  2. Who will be the end user of the multimedia product?
  3. What multimedia components (Video, Audio, Text, Graphics, animation, etc.) would bet deliver the multimedia message?
  4. What multimedia resources (existing material, money, personnel, multimedia equipment, time, etc.) are available for the multimedia product development?
  5. Is the multimedia product idea based on existing theme that will be improved through multimedia, or is it a totally new concept?
  6. What are the hardware/software constraints for the multimedia development project?
  7. What hardware is available to the multimedia product end user?
  8. What are your multimedia project team members capabilities and skills?
  9. Are there time and money constraints on the multimedia project?

FLOW CHARTING or mapping the structure of a multimedia project, must be started early in the organizing/planning stage of every multimedia project.  When meeting to discuss themes, goals, objectives, etc..., sketching flow charts and specific rough storyboards help to get complicated ideas into a visual and understandable form.  Flow-charting provides the developer with a table of contents, a graphic look at the logical flow of the project components, as well as the flow of human interactive interface.

Four primary types of flow charts are used in multimedia project planning:

Linear flow charts provide a visual outline or map to navigate sequentially from one program screen or bit of information to another.  That is, a linear program will take the user from a point A to point B along a predetermined path.  The user has no control over the path followed or the final destination of the program. A good analogy of a linear flow chart would be an escalator, it automatically takes them to a predetermined location.  The user has no control of over where the escalator goes.  This is the same way linear programs work.  Linear flow charts allow litter or no human reaction.

Hierarchical provide a visual outline or map for navigating along branches of logical information. These branches depict a tree structure that is shaped by the logic of the content presented.  A hierarchical program allows the user limited control over the flow of the program.  The user is limited to navigating one branch at a time.  While the user can select any branch, the program is limited to the select branch, which must be exited before the user can move to another branch.  A good analogy of a hierarchical flow chart would be an elevator.  While on the elevator, the user can select any floor, for example the second floor.  Once the user gets off the elevator, they can explore all the rooms on the second floor. To explore rooms on the other floors, the user must exit the second floor back to the elevator and choose the desired floor. Hierarchical flow charts allow for limited human reaction.

Composite flow charts provide a visual outline or map for navigating along both sequential and hierarchical paths.  A composite program allows the user to moderate control over program flow.  The user may be occasionally constrained to follow a linear presentation or a hierarchically organized information.  A good analogy of a composite flow chart is a multi-level shopping mall with both elevators and escalators.  The user is free to explore the level.  Most interactive multimedia projects are developed using composite flow charts.  General information such as directions and introductions are provided in linear fashion, while specific content information is presented hierarchically.  Composite flow charts allow for moderate human interaction.

Non-linear flow charts provide visual outline or map for navigating freely throughout the project content, unbound by predetermined paths.  A truly non-linear program would allow the user to move from any program point to any other point at any time.  A good analogy of a non-linear program is difficult to design, requiring multiple menus option keys, and hot spots on every screen.  Non-linear flow charts allow for maximum human interaction.

CONCEPTUAL FLOWCHARTS AND STORYBOARD usually consist of very rough sketches about ideas, path of interaction, minimal content, structure, etc... working and/or final flowchart and storyboards are based on these sketches.

CONTENT DEVELOPMENT is by far one of the most time-consuming and expensive tasks in multimedia projection is collecting and validating the project's content.  It is of utmost importance that the project team plans ahead and allows enough time to collect and validate the content prior to starting the production phase.

PROJECT TEAM MEMBER COMMUNICATION - For any team project to be successful, it is imperative that all team members communicate well with each other.  Listed below are 12 communication errors that must be avoided if team members are to communicate effectively.  Avoid:

  1. sending negative body language.
  2. showing disrespect for other's work habits.
  3. failing to start and end meetings on time.
  4. allowing phone calls to interrupt discussions.
  5. criticizing and correcting people in public.
  6. cutting people off in mid-sentence.
  7. "apologizing" for speaking.
  8. failing to present arguments logically.
  9. "carrying a chip on your shoulder" (cliche') into communications
  10. being ego-involved in communications.
  11. disagreeing disagreeably.
  12. being inflexible.

Unit 4: Designing the Multimedia Project
Top

This unit will show students how to develop the final planning stages for designing a multimedia product.  In this unit, students will identify available multimedia resources and formulate final developmental plans utilizing storyboards for each screen of the multimedia project.

Unit Objective

Upon completion of this unit, the student will be able to:

Unit Information

Storyboarding

As described in Unit three, flow charts outline the connections and pathways between the various content areas.  While flow charts furnish the roadmap, storyboards provide the specific screen by screen detail on how multimedia components (video, audio, clipart, text, animation, digitized stills, and data ) are to be employed.  Storyboards are in effect, married to the flow chart during the entire design process.  Messages and content should be organized along a stream of major topics that permit the user to follow a logical sequence of events, but also go back to the previous screen.  Three primary types of storyboard used in multimedia product development are conceptual storyboards, designer storyboards, and programmer storyboards.

The CONCEPTUAL STORYBOARD is the simplest, providing the design specialist with a rough outline from the client of their initial concept for the project.  The conceptual storyboard is very informal and may consist of written notes, stick-figure sketches, or a combination of the two.  Conceptual storyboards provide only a rough outline.  Two or three storyboards may cover the entire project.

The second type of storyboard is the DESIGNER STORYBOARD.  Designer storyboards provide detailed information and development parameters for each screen to be presented.  When all storyboards are placed in sequential order, they form a detailed outline of flow, interaction, information, and resources needed to complete the multimedia project.  Each storyboard lists all the resources, information, and design ideas required to deliver one screen to the user.

While designer storyboards are detailed and provide specific design parameters, they are not etched in stone and can be changed if needed.  Though there are many storyboard formats available, the format selected is far less important than ensuring that all needed information and parameters are provided for development.

The third type of storyboard is the PROGRAMMER'S STORYBOARD.  This type has all the information found on the Designer Storyboard, plus file names and locations for all resource components needed for programming.  Unit Five will provide more detailed information about Programmer Storyboards.

Storyboard Design Tips

  1. Utilize contrasts such as dark/light, bright/dull, big/small, thick/thin
  2. Maintain clean screens with lots of open spaces.  Try to avoid a cluttered screen that could draw the user attention away from the main point.
  3. Utilize shadows and shades.
  4. Incorporate eye-catchers such as Italics, capital letters, bolding, a single brightly colored object, an animated object, etc.  Use only one eye-catcher per screen, in order to focus' attention to that point only.  More than one eye-catcher can distract ad confuse the user.

Design Mistakes to Avoid

  1. Busy or cluttered screens.
  2. Repeated use of the same graphic or animation. If it doesn't have a purpose, don't include it.
  3. Clashes of color.
  4. Filly patterns and borders.
  5. Too much data or text (limit table and charts to about 25 numbers, split text into bit sized chunks).  (NOTE: desired font size 28 to 40 point).
  6. Short, quickly displayed screens (allow the user time to absorb the message but don't bore them either).
  7. Using the same music or sound effects over and over again. (This may distract and irritate the user).
  8. Invoking sound effects when buttons are pressed.  (Clanging bell or squeaks may also be irritating to the user).
  9. Non-exitable products (If the user does not like it or is not interested, let them out).

Remember that storyboards are not set in concrete.  If a storyboard concept does not work on the screen, change the storyboard.  Multimedia design and development may require many hours of editing and fine tuning to achieve the effect that works just right.

Using Designer Storyboard Worksheets

The designer storyboard worksheet consists of three main areas: The storyboard information area, the screen parameters area, and the screen graphics area.

The Storyboard Information Area includes the storyboard title that identifies the screen that the storyboard represents.  For example :Opening information  - Screen #2" or "Branch 2 - Screen 6", etc.  This area also includes the screen objective, which briefly summarizes the screen components and their order of occurrence.  For example, "Background music begins to play, background graphic fades onto screen, music fades, text rolls up as narration plays."

The Screen Graphics Area is the centered box area in which the designer provides visual of graphical representations of the screen's appearance.  The designer provides details of pictures, text, positioning, etc., as they will appear o the screen.  The more specific the detail, the more likely the programmer will carry them out as the designer envisioned.

The Screen Parameters Area is the area around the graphics box in which the designer writes detailed information concerning needed resource components.  The designer may also include such specific information as color, text style, sizes, location, etc.  For example, "Background music-high tech sounding music," or "Background Video-Hyperspace stars rush toward the viewer from center screen."

Unit 5: Preparing to Program the Multimedia Project
Top

In this unit students will plan and prepare to program a multimedia project.  Students will learn to identify and locate multimedia resource components to be used in programming.  Students will then compile this information into a programmer's storyboard.

Unit Objectives

Upon completion of this unit, the student will be able to:

Unit Information

The programmer storyboard, like the designer storyboard, provides detailed description of the resources needed to deliver the planned content.  In addition to providing detailed screen information and parameters, the programmer's storyboard adds component file name and their locations.  If the storyboard had a video component, the component's file name and location would be listed under the video section of the programmer's storyboard.  The proper recording format would include a file location, file name and file extension, for example,

D:\VIDEO\CHS.AVI
D:\GRAPHICS\GROUP.JPG
D:\AUDIO\WORLD2.WAV

D:\indicates the drive location.
VIDEO is the subdirectory name.
CHS is the file name.
AVI is the 3 character file extension.

Clear communication between designers and programmers is crucial to accurately transform creative visions to the screen.  Programmer's storyboards with detailed descriptions of all components, provide programmers the blueprint to build the multimedia product as envisioned.

The designer's storyboard forms the framework for developing the more detailed programmer's storyboard.  Each resource produced adds specific description and file information for the components they are responsible for.  The programmer's storyboards are then reviewed for accuracy and coherence by the entire production team before they are given to the programmer.  It is most helpful for the programmer to participate in storyboard review sessions to hear specific comments and clarify any questions regarding design aspects.  Again, storyboards are never set in concrete.  The programmer may find that an effect of file cannot be used with a particular software.  Some hardware constraints may necessitate storyboard changes.  Designers and programmers working together and communicating effectively can ensure that the intended message remains on target despite revisions.

Tips for Developing Programmer Storyboards

  1. Try to utilize the KIS (Keep It Simple) principle. Elaborate special effects may look impressive, but the hardware and software required to carry them out can be prohibitively expensive.  Complex programming takes more time to produce, and time is money.  Elaborate (costly) design elements should be employed only to the extent that they uniquely enhance program objectives.
  2. Store resource component files in easily accessible locations.  Avoid putting files in locked or inaccessible directories or location.  If the programmer cannot get to the files when needed, production will be delayed.
  3. As a resource component producer or design specialist, discuss complex effects with the programmer before programming begins.  It can be very frustrating to spend many hours working on something only to be told, "That's not what I wanted" or "It can't be done that way."
  4. Do not place the resource component file name and location on the programmer's storyboard until the component is tested and complete.  Programming a sequence only to find it must be redone because a component file is incomplete can strain team relations and waste valuable time.
  5. If a problem is encountered during programming, consult with other team members.  A collaborative approach and a fresh perspective can often find the means to solve a problem.

Unit 6: Screen Design, Using Color, & Creating Animation
Top

In this unit students will learn how screen design affects users, and what the common practices are in multimedia screen design.

Unit Objectives

Upon completion of this unit, the student will be able to:

  1. Identify the effects of screen design on users
  2. List common practices of screen design.

Unit Information

Basics - The purpose of the educational multimedia screen is to convey information that the student is to acquire.  The placement, consistency, appropriateness, and color of the information are important to the comprehension, usability, and retention of the information.  This is true for all visual communication.  It is very important in educational multimedia.

There is a tendency among novice multimedia creators to fill the screen with words, graphics, animation, video, etc., to make the presentation exciting.  While gaining and keeping attention is important, it is more important to convey the information.  Dazzling effects should be used sparingly, and only when they add to the learning experience.

Balance

                                    A                                                                                       B

Balance is achieved when objects on the screen are evenly spaced on the screen, so that the screen does not appear to want to tip over.  Figure A shows an unbalanced screen where the objects are weighing down the right side of the screen.  Figure B shows the same objects arranged in a balanced lay out.

                                   C                                                                                        D

Balance can either symmetrical of asymmetrical.  Figure C is symmetrical.  Figure D is asymmetrical. Both are balanced.

Unit 7: COLOR
Top

Unit Introduction

In this unit students will learn how color schemes affect users, and what the common practices are in multimedia color usage.

Unit Objectives

Upon completion of this unit, the student will be able to:

  1. Identify effect of color on users
  2. List common practices of color usage.

Unit Information

Basic Color

Color is a powerful tool in the multimedia kit.  Used properly, it can improve learning, navigation, aesthetic presentation and concentration.  Used improperly it can be distracting, overwhelming, and even painful.

Color schemes commonly fall into three categories: monochromatic, complementary, and analogous.  Complementary colors are opposite each other on the color wheel (Figure 1).  Every color has an opposite color (figure 2).

 

RED - GREEN
VIOLET - YELLOW
BLUE - ORANGE

These color combinations offer the highest color contrast available.  While contrast is desirable in many situations, to highlight important words, or draws attention to a new navigation option, excessive use of highly contrasting colors can cause eye fatigue and even headaches.

Monochromatic color schemes are combinations of colors of the same hue.  These color combinations offer less contrast than complementary but are easier on the eyes.  they make for a more relaxed and comfortable viewing experience.

Analogous colors are next to each other on the color wheel and are closely related.  For example, blue, blue-green, and green all have the color blue in common.  Families of analogous colors include the warm colors (red, orange and yellow) and the cool colors (green, blue and violet).  Analogous colors are sometimes referred to as adjacent colors.

Symbolic colors can be used to represent something else or a feeling.  Soft pastels can give a feeling of serenity. while reds and dark violet can give a sense of urgency or danger.  Many colors are used universally for communicating material.  White can represent purity while green can represent nature.

Other Color Concerns:

Age of the end user makes a difference; children prefer warm colors, while adults prefer cool colors.  Drop shadows are placed on text to separate it from the background.  When there is text that is similar in intensity to the background, it is important to add a drop shadow.  Drop shadows do not need to be black.  If the program will be shown on an LCD projector, the colors need to be more intense.  They will wash out during projection.

Unit 8: ANIMATION
Top

Unit Introduction

Students will be provided the opportunity to learn what types of animation are used in multimedia, what the common practices and terms are in animation, and how to use animation to improve educational effectiveness of multimedia productions.

Unit Objectives

Upon completion of this unit, the student will be able to:

Unit Information

Animation can add visual impact to the multimedia project.  Designers can animate the entire project or can animate here and there to emphasize a message or attract the viewer's eye.  In a multimedia production, animation can range from the most basic use of wipes, fades, zooms or dissolves to true object location movement where objects may appear to spin or move across the screen.  Before the introduction of motion video, animation provided the primary means to employ action and movement in multimedia presentations.  Applied intelligently, animation can be a great attention grabber, focusing viewer awareness wherever needed.  Animation can also be detrimental if improperly applied.  Overuse can make a screen appear excessively busy and distracting.

Types of Animation

  1. Moving objects across the screen.
  2. Highlights
  3. Transitions
  4. Full animation files

Moving an object can achieve several instructional goals.  An object moving across the screen can gain the users' attention. Gaining attention is the first of Gagne's nine events of instruction. Moving objects across the screen can show the relative position of objects such as moving a graphic of a car part to its proper location.  This may provide for another instructional event, perhaps both maintaining attention and providing guided learning.  The movement of an object across the screen can be automatically accomplished or the result of user interaction. The user could move the car part to the proper location. Users dragging objects to proper locations may be a good way to elicit performance or assess performance.

An animation can be used to highlight details or specific information. Highlighting information is a good way to recall prior learning, present new materials or provide guided learning.

Animation can be used as a transition between information on a frame.  Such a dissolving between two text objects to avoid cluttering the frame.

Animation Tips to Remember Include:

  1. Animation, like any multimedia component, should have an instructional purpose, and be assignable to one of Gagne's events.
  2. The smaller the object, the faster it can move.
  3. The smoothness of the animation will depend on the computer's speed. If the computer cannot compute the changes and display them on the monitor as a new frame within about 1/30 second, then the animation may appear slow and jerky.
  4. Animation segments should be kept brief. Long, continually repeating segments can quickly become boring for the viewer.
  5. Avoid multiple animations on one screen.  They can make a screen appear too busy and may district the viewer from the intended purpose.
