Cambridge IGCSE ICTAudiences
This chapter focuses on two areas: audience appreciation and copyright. When creating an ICT solution, it is important to make sure it is suitable for the people who will use it. The chapter also explains how software is protected by copyright law and how software piracy can be reduced.

9.1 Audience appreciation
Audience appreciation means considering the characteristics and needs of the people who will use or view an ICT solution.
What can an ICT solution be?
a presentationa websitea computer gamea databasea virtual reality system
A solution that is suitable for one audience may be unsuitable for another.
Giving a presentation to an audience
Before creating a presentation, consider the audience's:
age
experience
expectations
knowledge
For example, a presentation for young schoolchildren should be very different from one designed for company directors. Similarly, a technical audience may understand specialist terminology that an ordinary audience would not.
Finding out about the audience
Information about the target audience can be collected using:
interviews
questionnaires
online surveys
The results can then be analysed to identify patterns and help design an appropriate solution.
Important factors when creating a presentation
Language used
The language should suit the audience.
Avoid offensive or inappropriate language.
Technical terms should mainly be used when the audience understands them.
Younger or less experienced audiences may need simpler explanations.
Multimedia
Multimedia includes:
imagessoundvideoanimationgraphs
Multimedia can make a presentation more interesting, but too much can distract the audience from the main message.
Length of presentation
The presentation should not be unnecessarily long. Young audiences, in particular, may lose interest quickly.
Interaction
The presenter may involve the audience by:
asking questions
allowing people to try something
including interactive activities
However, not everybody may want to participate.
Examples
Examples should:
be relevant to the audience
be easy to understand
avoid causing offence
Same information, different audiences
Suppose a mobile-phone company creates two presentations:
Presentation for sales staff
The audience may want:
technical details
profitability
information about selling the products
Presentation for customers
Customers may be more interested in:
price
phone features
how the product benefits them
Therefore, the same product may need to be presented differently depending on the audience.
Audience characteristics when developing an ICT solution
When developing something such as a website, important audience characteristics include:
age rangeincomeinterestsdisabilities or impairments
Age
Young children may prefer
bright colours
large fonts
animations
sound
more pictures and less text
Older users may prefer
clear content
simple navigation
easy-to-read layouts
Income
Income may affect what products or services should be advertised.
For example, a car website aimed at people with lower incomes would probably advertise different models from one aimed at wealthier customers.
Interests
The content should match the audience's interests.
For example, a music website should provide information about the types of music its target users prefer.
Disabilities
An ICT solution should also consider users with disabilities.
For visually impaired users, useful features may include
larger fonts
contrasting colours
less unnecessary text
sound
Needs of different age groups
| Audience | Some suitable features |
|---|
| Young children | Bright colours, animation, sound, large fonts, simple words, many pictures |
| Adults/older children | Attractive design, interesting content, mixture of text and images, suitable language |
| Older people | Larger fonts, contrasting colours, simple interface, consistent page design |
Why audience needs are important
Considering the audience helps make an ICT solution fit for purpose. It can:
make information easier to understand
make the interface easier to use
keep users interested
make the solution accessible to users with disabilities
encourage people to continue using the website or system
Poorly designed interfaces, complicated language and too much typing can frustrate users and cause them to stop using the system.
Easy exam idea: Who are they? → What do they need? → How should the ICT solution be designed for them?
9.2 Copyright
Copyright legally protects software and other creative work.

Software copyright
Without permission or the correct licence, it is illegal to:
copy software and sell or give it to another person
install software on several computers when the licence does not allow this
copy programming code and claim it as your own
rent software without the publisher's permission
Software piracy
Software piracy is the illegal copying of software.
It causes problems for software companies because illegal copies may be distributed without the copyright owner's permission or payment.
Ways of protecting software
Several methods can help prevent illegal copying.
Product key
During installation, the user may have to enter a unique product key. This is usually a combination of letters and numbers supplied with the genuine software.
Licence agreement
Before installing software, the user may have to select I AGREE. This confirms that the user accepts the conditions of the software licence.
Hologram
Original software packaging may contain a hologram to show that it is genuine.
Original media required
Some software only works when the original:
CDDVDmemory device
is present.
Dongle
A dongle is a small hardware device, often connected through USB. Some software only operates when the correct dongle is connected to the computer.
Copyright infringement
Copyright infringement occurs when someone breaks copyright law, for example by illegally copying, selling or distributing copyrighted software.
Organisations can take legal action against people or companies involved in software piracy. The book gives examples of organisations created to protect software and other intellectual property from illegal copying.
