What is HCI?
HCI is concerned with
Designing computer systems to match the needs
of its users
The aim of HCI is
“…to develop or improve the safety, utility,
effectiveness, efficiency, and usability of
systems that include computers”
(Interacting with Computers, 1989 )
What is HCI?
HCI draws from the knowledge and methods
of many different disciplines, chiefly
–
–
–
–
computer science
cognitive psychology
social sciences
ergonomics or human factors
HCI and Computer Science
 Computer Science contributes knowledge
about technology and a wide assortment of
software tools and methods for design and
development
– Graphical User Interfaces
– Prototyping tools and techniques
– Object orientation etc.,
HCI and Cognitive Psychology
Cognitive Psychology contributes knowledge
about the capabilities and limitations of its
users.
– Human Information Processing
– Perception
– Memory
Social Psychology
 Social science contributes explanations
about the structure and functions of humans
in collective behaviour
– organisational theory
– task analysis
HCI and Ergonomics
Ergonomics contributes an understanding of
the environment in terms of the comfort,
health and safety, and optimally productive
conditions for work
– Screen layout design, colour etc.,
– Design of software and hardware
HCI Design
HCI design should be
– user-centred
– integrative of contributing disciplines
– highly iterative
Evaluation should be at the centre of all HCI
design activity
The Components of HCI
Implementation
Task analysis/
Functional analysis
Prototyping
Evaluation
Conceptual design/
formal design
