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
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’.

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
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

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 Introduction
accomplish
- PTIIK UBsomething.

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
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
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



user interface design and evaluation


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
