1. Business Engineering and Management Introduction Ebba Thora Hvannberg

2. Objectives Understand the concepts underlying the design of interactive systems Understand why being human-centred is important in design Understand the skills and knowledge that the designer of interactive systems needs to draw upon

3. Variety Se Wii Second Life iPhone

4. 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

8. Benyon, Designing Interactive Systems: A comprehensive guide to HCI and interaction design, 2nd Edition, © Pearson Education Limited 2011 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.

9. Benyon, Designing Interactive Systems: A comprehensive guide to HCI and interaction design, 2nd Edition, © Pearson Education Limited 2011 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 is based on scientific knowledge Design as art Frank O. Gehry – Guggenheim safnið í Bilbao

10. 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.

11. 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

12. People and technologies What is the difference between technologies and people

13. 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. F The team observed ATM users in Spain, Mexico, and the US From ideo.com

15. 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.

16. 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

17. 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?

18. 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?
