4. Automatic Syringe Introduction - PTIIK UB 2013

5. Why HCI? • The interface should not just present a ‘pretty face’, but should support the tasks that people actually want to do, and forgive the careless mistakes. • It is not at all intuitive or easy to design consistent, robust systems that will cope with all manner of user carelessness • The interface is not something that can be plugged in at the last minute; its design should be developed integrally with the rest of the system. Introduction - PTIIK UB 2013

6. Why HCI? • Part of law in developed countries, e.g.: • National health and safety standards constrain employers to provide their workforce with usable computer systems: not just safe but usable. Introduction - PTIIK UB 2013

7. Why HCI? • Part of law in developed countries, e.g.: • EC Directive 90/270/EEC requires employers to ensure the following when designing, selecting, commissioning or modifying software: • that it is suitable for the task • that it is easy to use and, where appropriate, adaptable to the user’s knowledge and experience • that it provides feedback on performance • that it displays information in a format and at a pace that is adapted to the user • that it conforms to the ‘principles of software ergonomics’. Introduction - PTIIK UB 2013

8. What’s HCI? • Term only been in widespread use since the early 1980s • But has its roots in more established disciplines • Systematic study of human performance in factories, emphasis on manual tasks, the early 1900s • Study of interaction between human and machines, World War II (1939-1945), for more effective weapon systems • After WWII, the Ergonomics Research Society, 1949 • Ergonomics (UK)  Human Factors (North America) • Man-machine interaction • Human-computer interaction Introduction - PTIIK UB 2013

9. What’s HCI? (cont’d) From Computer Science and Systems Design view: • HCI involves the design, implementation, and evaluation of interactive systems in the context of user’s task and work Introduction - PTIIK UB 2013

10. HCI Main Components • The human: • an individual user, • a group of users working together, or • a sequence of users in an organization, each dealing with some part of the task or process • The computer: • any technology ranging from the general desktop computer to a large-scale computer system, a process control system or an embedded system. • The interaction: • any communication between a user and computer, be it direct or indirect. • The important thing is that the user is interacting with the computer in order to accomplish something. Introduction - PTIIK UB 2013

11. Who’s involved in HCI? • A multi-disciplinary subject • An ideal designer would have such expertise in: • Psychology and cognitive science • Ergonomics • Sociology • Computer science and engineering • Business • Graphic design • Etc. • However, that’s too much for one or even four persons! • But, we cannot design from one side in isolation! • So… let’s have stance on one side and consider inputs from other sides where relevant Introduction - PTIIK UB 2013

12. Who’s involved in HCI? (cont’d) • Our stance as computer scientists: • “How do principles and methods from each of these contributing disciplines in HCI help us to design better systems?” Introduction - PTIIK UB 2013

13. Triple ‘Use’-s • Useful – accomplish what is required: play music, cook dinner, format a document; • Usable – do it easily and naturally, without danger of error, etc.; • Used – make people want to use it, be attractive, engaging, fun, etc. Introduction - PTIIK UB 2013

14. Craft or Science? • HCI is both craft and science! • Lesson learned from Architecture • Beauty, innovation, imagination, creativity provide aesthetic pleasure and requires inventive inspiration and intuition... It’s art and/or craft! • However, we need to understand not only that they work, but also why and how they work... • Hence, understand the reasoning and be able to reuse the principles... It’s science! Introduction - PTIIK UB 2013

15. Learning Objectives • Understand the characteristics of the fundamental components of an interactive system: • the human user, • the computer system • the nature of the interactive process • Understand the design process of an interactive system • Apply appropriate principles, models, and techniques of user interface design and evaluation Introduction - PTIIK UB 2013

16. Main Topics • Foundations • The human • The computer • The interaction • Paradigms • Design Process • Interaction design basics • HCI in the software process • Design rules • Task analysis • Implementation support • Evaluation techniques Introduction - PTIIK UB 2013

20. Learning Principles • Spirituality on Learning • Positive attitude • Learning is not a choice, but a natural obligation • Pray for beneficial knowledge • Prepare yourself for knowledge… • ..because knowledge is light, will enlighten, and it only comes to those who are ready • Community of learners • All of us are learners • Everyone should be self-directed, active, and critical • Unlimited learning resources Introduction - PTIIK UB 2013
