Why are visual communications made differently?
Reasons for visual communications
A visual communication is a commercial product that is intended to perform a particular function. Each visual communication is created for a reason. There are several different reasons for making of visual communications. The reasons are known as the purpose.
The VCAA Study design for Visual Communication Design (2018-22) defines purposes on p22, as to;
- advertise,
- promote,
- identify,
- depict,
- teach,
- inform,
- guide
There are many other reasons why people communicate visually, for example to decorate, to express feelings, or commemorate events. However, this is the list for our study.
This page defines each purpose and gives a model analysis of each.
A distinction between purpose and function
As our subject does not require students to make functioning prototypes, we are mindful of how we discuss the purpose of a visual communication. The photo at right shows a coffee percolator. The function of the percolator is to make coffee. However, the purpose of the photo is to depict and advertise it.
Similarly, the image at far right is a magazine advertisement. Its purpose is not to make coffee but to advertise.
When students are writing about the purpose of their own visual communications, they should refer to their proposed presentation format. Therefore, its likely they’re making presentations that depict, promote or advertise objects rather than make presentations that perform the function intended for the object itself.
By contrast, if an examination question asks a student to identify and/ or explain the function of a product, they should discuss what it actually does and not refer to the purpose of the image which would be to depict.


Model purpose analysis

Sample question
Identify its purpose of the image at left and explain how one design element and one design principle support the purpose.
Sample answer
The purpose of the poster shown at left is to advertise a movie about Princess Diana. Advertising the movie people will generate sales for the producers. Type and balance have been used effectively for the purpose. A fine serif type like those used in glamour magazines, has been used for on the poster. It is capitalised which eludes to the importance of Diana. The serifs complement the crown graphic, adorned with flourishes above Diana's name. A strong asymmetrical balance has been created by her face which is off-set to the right. This position, coupled with severe cropping of the left side of her face eludes to her difficult and sometimes dangerous life within the British Royal Family. The use of type and balance both refer to the role and position of Diana and support this image in its purpose as an advertisement for a figure who met with such immense tragedy.
Purposes.
Demographics are facts about an audience.
Advertise
To advertise is to present a product or service for the express purpose of sales or financial gain.

Examples of advertisements are;
- posters,
- signs,
- multi-media kiosks/ displays,
- post cards,
- billboards,
- magazine ads,
- flyers.

Model analysis
The poster at left is advertising apples. The fresh green apple contrasts strongly with a vibrant red background. The shine across the format emphasises the freshness. The information 'Apples' and price are presented clearly for the target audience. It is clearly intended for selling apples.
promote
To promote is to present a product, service, idea, concept, belief or ideology for persuasion of an audience for the better of the individual, community or society as a whole. Promotion may be confused with advertising as the techniques are similar. However, the easy way to distinguish is to ask, does the visual communication lead directly to sales and financial gain? If not, it's likely to be promoting something.

Examples of promotional products include;
- political campaign materials,
- Church posters,
- posters to engage audience in social issues,
- flyers to engage audience in healthy eating,
- symbols.

Discuss
Model analysis
This poster at left is intended to promote apples by communicating the idea that eating them is healthy. It uses simple images composed of stylised shapes and bright contrasting colours. It also uses the metaphor of love hearts, hovering over eyes to show that apples bring health and happiness when eaten.
Identify
To identify is to enable easy recognition of a person, company or location.
A written or visual mark like a logo is used to help people recognise a brand.
Logos and other visual devices are often registered as trademarks to ensure exclusive use by the owner.

Examples of identifying products include;
- logos,
- trademarks,
- colours,
- monograms,
- icon,
- signs,
- webpage banner,
- newspaper masthead,
- badges,
- heraldry and coats of arms,
- flags.

Model analysis
The presentation at left shows apple logos on clothing. They identify a company for a target audience. Colour and simple shapes have been used to contrast with their background to enable instant recognition for this company.
Depict
To depict is to make an image or model of something. Depictions are often used in visual communications with other purposes.

Examples of depictions include;
- freehand illustrations,
- two and three dimensional illustrations - 3rd Angle orthogonal, paraline and perspective drawings,
- paintings,
- prints,
- photographs,
- digital 3d models,
- holograms,
- video installations,
- model making,
- dioramas,
- prototypes,
- mock-ups,
- schematic architectural drawings,
- pictograms,
- icons.

Model analysis
The illustration of an apple is intended to depict this lovely piece of fruit. It uses realistic colours, stylised shape and tone to represent form.
Teach
To teach is to facilitate learning. To teach usually involves simplifying information into a sequence or steps. To teach may be confused with to guide, and inform. One way to differentiate between them is to ask, does the visual communication explain something with a sequence?

Examples of teaching products include;
- webpages (like this one),
- magazine and book spreads,
- posters and wall charts,
- post cards,
- videos,
- models,
- digital apps,
- explanatory diagrams.

Discuss
Model analysis
The chart at left is intended to teach someone how to peel, cut and eat slices of apple. It uses simple shapes and colours that contrast well with the background to illustrate the process. Teaching how to peel, cut and eat has been broken down into steps. Symmetrical balance, contrast and figure-ground have been used to ensure clarity.
Inform
To inform is to provide information or facts. As distinct from to teach, to inform does not seek to enable learning but to communicate information such as a rule, date, or event.

Examples of informing products include;
- posters,
- flyers,
- webpages,
- post cards,
- billboards,
- multi-media kiosk screens,
- brochures,
- map,
- symbol.

Discuss
Model analysis
The image of a calendar page marked with an apple over a date is intended to inform the audience that this day is significant for apples. Colour has been used to attract attention as the apple is shown in a cool green which contrast sharply with the rest of the illustration which is made in warm red tones.
guide
To guide is to provide directions or information to assist someone to locate something. As distinct from to teach, to guide shows a member of the audience where something is and/ or how to find it in relation to other features. The goal is location not learning.

Examples of guiding products include;
- maps,
- brochures,
- posters,
- instructions,
- diagrams,
- websites and webpages,
- interactive multi-media kiosks,
- digital way-finding apps.

Model analysis
This fruit tour map is intended to guide members of an audience to an apple store. It uses line, shape and colour to create roads, a river and fruit shapes.

Purpose examples







tasks
Understand purpose
- Identify the purpose of each of the visual communications above. Refer to the images when you give reasons for your answer.
- Choose one image and identify one design element and one design principle used effectively. Explain how the elements and principles you have identified support the purpose.
- Choose another image. Suggest a different purpose and explain how it would need to be changed in order for it to suit a new purpose. In your answer refer to design elements and design principles.
