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.

Introduction - PTIIK UB 2013

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

Introduction - PTIIK UB 2013

HCI Main Components

Introduction - PTIIK UB 2013

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 2013

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 2013

Our stance as computer scientists:– “How do principles and methods from each of these contributing

disciplines in HCI help us to design better systems?”

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

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

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

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

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

Have a nice journey of learning!
