1. Fundamentals of Human Computer Interaction (HCI)

2. What is HCI? HCI is concerned with The aim of HCI is
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 )

3. 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

4. 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.,

5. HCI and Cognitive Psychology
Cognitive Psychology contributes knowledge about the capabilities and limitations of its users.
Human Information Processing
Perception
Memory

6. Social Psychology
Social science contributes explanations about the structure and functions of humans in collective behaviour
organisational theory
task analysis

7. 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

8. 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

9. The Components of HCI Task analysis/ Implementation
Functional analysis
Implementation
Requirements
Specification
Prototyping
Evaluation
Conceptual design/
formal design
