What is Multimedia?
How do you define multimedia in today’s e-Learning context?
It can be defined as tools engaging learners interactively.
Activity 3.2
A multimedia instructional message is a communication using words and pictures that is intended to promote learning.
For example, a multimedia instructional message in a book could include printed text and illustrations, whereas a multimedia instructional message on a computer could include narration and animation.
Examples of multimedia instructional messages include words and pictures intended to explain how lightning storms develop, how car braking systems works, and how a bicycle tyre pumps work.

7 Principles of Multimedia Design
1. Multimedia principle: Students learn better from words and pictures than from words alone.
2. Spatial Contiguity Principle: Students learn better when corresponding words and pictures are presented near rather than far from each other on the page or screen.
3. Temporal Contiguity Principle: Students learn better when corresponding words and pictures are presented simultaneously rather than successively.
4. Coherence Principle: Students learn better when extraneous words, pictures, and sounds are excluded rather than included.
5. Modality Principle: Students learn better from animation and narration than from animation and on-screen text.
6. Redundancy Principle: Students learn better from animation and narration than from animation, narration, and on-screen text.
7. Individual Differences Principle: Design effects are stronger for low-knowledge learners than for high-knowledge learners and for high-spatial learners rather than low-spatial learners.
Activity 3.3
Exploring Visual Design
“At the beginning of a project, the screen is a blank canvas, ready for you, the multimedia designer, to express your craft. The screen will change again and again during the course of your project as you experiment, as you stretch and reshape elements, draw new objects and throw out old ones, and test various colors and effects – creating a vehicle for your message…many multimedia designers are known to experience a mild shiver when they pull down the New… menu and draw their first colors onto a fresh screen…this screen represents a powerful and seductive avenue for channelling creativity.”
Tay Vaughan, 1998
Visual design takes the composite of elements: text, symbols, photos, colours, video, in fact any graphic element and much more, to communicate your message – it is your primary connection with the learner.
Visual design is the process of producing visual images that are able to communicate information to other people.
Visual images are made up of lines, colours, textures, tones, hues and shapes applied in a spatial composition. We are surrounded by visual images in our everyday lives. Each visual image is trying to tell us something.
To produce images that people understand, you need to consider the following:
What message are you trying to communicate?
What audience are you trying to communicate with?
What is the best way to visually communicate that message?
What are the elements and tools necessary to produce the visual image?

Understanding Perception
When you look at a visual image you see lines, shapes, colours, tones, hues and objects in a spatial dimension.
The eye collects visual information from these images and objects and this information is transmitted to the brain. The brain interprets and constructs meaning from this visual information.
To design visual images that are meaningful to an audience you need to understand the way your audience actually sees. That is, how does the eye collect visual information and how does the brain interpret it? This line of inquiry is called the science of perception.
Discovering the way the eye works will help you understand how visual elements function in visual design.
Understanding Visual Communication
No two people ever see the same thing quite the same way. Cultural differences, the level of acquired knowledge, an individual’s psychology and socialisation will all affect the way we construct meaning from a visual image.
Physiology can also affect the way a person sees. The eye itself can have defects in the retina lens or suffer from colour blindness. The brain can also have its own problems that affect perception such as brain dysfunction, and alcohol and drugs.
To cater for these differences in perception you need to construct a clear, unambiguous image and know your audience well enough to construct visual images that they will easily recognise and comprehend. For example, a road sign needs to communicate its message to a wide audience instantaneously.

PRINCIPLES OF COLOUR
Understanding Colour
Review the Colour Matters site and determine why some colours appear to hurt the eye!
From the same site – Color Matters – explore how computers generate colours and what this can mean to your multimedia images:
The Psychology of Colour
Some colours make us happy and others, sad. Colours have the ability to provoke a psychological reaction. Look at the objects around you: their colours have been chosen specifically because they create a mood or an association for the viewer.
Because of their power to provoke reactions in us, we use colours for their symbolic meaning. It is no accident that fire engines are painted red; red is a hot colour and denotes the idea of danger. Police uniforms are blue; being a cool colour, blue projects the idea of being under control, being calm and collected.
You can use colours in your visual designs to convey a mood, create an association or express your feelings about a particular event, activity or object.
Choose colours to convey the following:
|
Aggression Friendly Solid Weak Serious Depressed |
Selecting Colours
Many things will affect your choice of colour. Consider the situation and choose your colours wisely. Think about the following factors.
Fashion
Colours go in and out of fashion. Bright colours are used to demand attention and make a statement. Designers of luxury items want their products to appear reputable and durable, and be seen to outlast the fashion of the day; gaudy colours such as bright pinks and yellows are unlikely.
Strong and bold colours are used to attract the mass market. Advertisers usually use primary colours because they are the most appealing colours to the bulk of the population.
The environment
Australians live in a hot, dry environment so often use cool colours (such as pastel tints) in their buildings to make their physical environment seem cooler. In a European environment that is predominantly cold you tend to see warm, bright primary colours, creating a cheerful, cosy illusion.Asia you will find temples painted in bright, primary colours. A European church is more likely to have more sombre colours.

Culture
Culture and history shape colour choice. If you visit
The following is a brief overview of the 4 basic principles of design :
C R A P

|
Contrast |
|
Contrast can be the most important visual aspect of a page. The principle is to avoid elements on the page that are merely similar – if they are not the same – then make them VERY different.
Purpose: To create interest Aid in the organisation of information Supports visual hierarchy Eg. use of colour
|
|
Repetition |
|
Repeat visual elements throughout – colour, shape, etc. Develops organisation and strengthens the unity.
Purpose: To unify and add interest For consistency Eg. navigation, colour identifiers, layout – anything your learner may visually recognize.
Avoid repeating the element so much that it becomes annoying and distracts from the message
|
|
Alignment |
|
Nothing should be placed on your page randomly. Every element should have some visual connection with another element on the page. This creates a clean, sophisticated look.
Purpose: To unify and organize your page design Be conscious of where you place your elements – always try to find something that aligns them
Avoid: More than 1 type of text alignment on the same page Don’t always centre align
|
|
Proximity |
|
Items relating to each other should be group close together. Items in close proximity become one visual unit rather than several separate, unrelated units.
Purpose: Reduces clutter and confusing your reader Organizes information – reduces cognitive load Logical information is more likely to be remembered |
