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.

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.

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’.

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

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

HCI Main Components
Introduction - PTIIK UB 2014
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.

Who’s involved in HCI?
Introduction - PTIIK UB 2014
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

Who’s involved in HCI? (cont’d)
Introduction - PTIIK UB 2014
Our stance as computer scientists:– “How do principles and methods from each of these contributing
disciplines in HCI help us to design better systems?”
![Page 13: HCI Introduction IA UB 2014](https://reader033.fdocuments.us/reader033/viewer/2022042721/577cc1a91a28aba71193a3f7/html5/thumbnails/13.jpg)
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.

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!

Understand the design process of an interactive system Apply appropriate principles, models, and techniques of
user interface design and evaluation

Learning and teaching spirit Intention:
– Positive and purposeful Daily obligation, competency, job prospect, worship
– Knowledge is important: Knowledge should come before action Knowledge shapes intention, intention affects everything You are more useful when knowledgeable
– Happiness vs fear: Find the right balance
– Always connect to the ultimate goal: Give the best to your Lord!

Learning and teaching spirit (cont’d)
Introduction - PTIIK UB 2014
Action:– Respect everyone
Everyone is a learner Lecturer is a facilitator, but a learner too... Listen, don’t disturb others Contribute to shared knowledge and collective intelligence
– Active and critical Being active increases intelligence, individually and collectively Being critical increases understanding
– Specific skills and transferable skills: IT/IS Skills Self-directed learning, Communication skills, etc
– Again, give the best to your Lord!

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
