Activity 3.1 What is multimedia?
“Multimedia is an eerie wail as two cat’s eyes appear on a dark screen.
It’s a small window of video laid onto a map of India, showing an old man recalling his dusty journey to meet a rajah there…”
Tay Vaughan, 1998, Multimedia: Making it Work
Multimedia is understood to mean a product that is digitally constructed utilising and seamlessly integrating various media: text, graphics, images, video, animation and sound.
Multimedia enriches the user through medias and technologies with the intention of engaging people’s minds!
Initially the delivery of multimedia products was via CD-ROM, but the internet provided a global distribution system that changed the structure and style of the multimedia products.
High levels of interactivity are now achievable using a range of software that runs on almost any current desktop computer.
The future of multimedia will be even more challenging as a plethora of delivery systems and displays are marketed. Enhanced program material provided on digital television and internet information displayed on mobile phones are just two examples of new multimedia systems.
Our notion of multimedia needs to encompass all new forms.

How do you define multimedia in today’s e-Learning context?
Compare this to the experiences with the Web 2.0 technologies and the issues raised in the Seely-Brown article.

Multimedia are applications installed into the page to provide the learner with better interaction and to be intrigued by the notion of learning through infotainment, have between entertainment and information. This is what is generally used in visual context of learning these days. New web pages are being developed quite creatively and web 2.0 is now utilizing these resources effectively as they enter social context as well as educational reasoning.

Activity 3.2 Principles of Multimedia
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.
Now consider your course and make notes where multimedia may be of value:
Task:
|
Consider the media elements in your design – use the questions above as a guideline if you are using animation, video or sound.
What are your recommendations?
Spatial- the students would learn better if the applications were close by to the related context
Multimedia principle- students will learn more effectively with there interaction with these applications.
Provided examples of multimedia elements you would recommend.
I would use MP3’S for audio files, Podcasts, Animations and 3d interactive navigation bars. I would also incorporate some innovative links and comment areas where the students could use an interface system to communicate with each other.

Activity 3.3 Visual Design
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:
1. What message are you trying to communicate?
2. What audience are you trying to communicate with?
3. What is the best way to visually communicate that message?
4. What are the elements and tools necessary to produce the visual image?
Complete the quiz in UTSOnline – Visual & Interaction Design – available in the Course Information tab.
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.

How would visual hierarchy influence learners?
|
Visual Hierarchy influences the learners by, the tones, colors and symbols or features that are placed on the web page. It will determine whether something has significant value or the information that is being highlighted stands out amongst the content that is been delivered to the learner. It determines the way the designer is trying to communicate with the learner by using the visual hierarchy. For example information in red is important and words that are bold with underline headings represent a title.
