Systems and People change

• One of the main challenges of design is to be able to take into consideration changes, learn from them and to predict them

The key concerns of the designer of interactive systems

• Design – what is design and how should you do it?

• Technologies – the interactive systems, products, devices and components themselves

• People – who will use the systems and whose lives we would like to make better through our designs

• Activities and contexts – what people want to do and the contexts within which those activities take place.

Design

• The term ‘design’ refers both to the creative process of specifying something new and to the representations that are produced during the process.

• Design as engineering which isbased on scientific knowledge

• Design as art

Design

• What is design? It’s where you stand with a foot in two worlds – the world of technology and the world of people and human purposes – and you try to bring the two together’. Mitch Kapor in Winograd (1996), p. 1

• The term ‘design’ refers both to the creative process of specifying something new and the representations that are produced during the process.

Evolution

• Most definitions recognize that both problem and solution need to evolve during the design process; rarely can you completely specify something before some design work has been done.

• Evolvability is a quality of software, minimizing the software changes but maximizing impact

People and technologiesWhat is the difference between technologies and people

User centered design • Being human-centred is about putting people first; it is about designing interactive systems to support people and for people to enjoy.

Why is human-centredness important?

• Return on investment– People’s acceptability of the system and the

processes a new system involves– People’s efficiency

• Safety – Interactive systems are used in transport,

medicine, at home.

Human-centredness

• Ethics– trust, intellectual Property right, Automaticity,

Autonomy, security, privacy. • Sustainability is the capacity to endure

– Durability of software and hardware – Impact on culture– Impact on resources

Challenge - exercise

• Find five interactive products or systems that you use- perhaps a coffe machine, a cellular phone, a TV remote control, a computer game and a website. Write down what it is that you like about each of them and what it is that you do notlike. Think about the whole experience. What do you agree on? What do you disagree on?

Challenge – exercise

• Look at your cell phone.

How have phones evolved? Have they changed in how you interact with them, what you do with them, who uses them?

Try to think back to your own childhood, or how you think phone have evolved since 50 or 100 years ago. What aspects come to mind?
