2. Today’s Learning Objectives
Understand the significance of Human
Computer Interaction (HCI)
Discuss and argue about why Human
computer Interaction (HCI) is important
Understanding Basic Concepts of HCI
Describe a formal definition of HCI

3. Human Computer Interaction?
• In daily life, we use/interact with various
devices/machines/systems to fulfill a task
or an objective:
• For examples:
– Computers
– Mobile Phones
– Cars
– Vending Machines (ATM etc )
– Many more…..

4. Human Computer Interaction?
• There is a huge diversity in
– Devices/Machines
– Types of Users
– Nature of Tasks/Objectives
– And, Ways of Interacting

5. Human Computer Interaction?

Interaction

6. Human Computer Interaction?
• It is a field of study that deals with:
– Humans (Users)
– Computers (Technology)
– Interaction (Any Communication)

7. HCI- Objective
• The objective of HCI is to :
“design interactive Products/Systems to
support people in their everyday and
working lives”.

8. HCI - Human
• Human?? Or User
• The user is whoever is trying to get the job
done using the technology
– An individual User
– Group of Users working together
– Sequence of users in an organization, each
dealing with some part of the task or process.
– A range of users???

9. HCI - Human

10. HCI - Computer
• Computer??
• any technology ranging from the
general desktop computer to a large-scale
computer system, a process control system
or an embedded system.
• Any other?

11. HCI- Computers

12. HCI - Interaction
• Interaction?? Any communication
between a user and computer
• Direct interaction involves a dialog with
feedback and control throughout
performance of the task
• Indirect interaction may involve batch
processing or intelligent sensors controlling
the environment.

13. HCI – Formal Definition
“Human-Computer Interaction is a discipline
concerned with the design, evaluation and
implementation of interactive computing
systems for human use and with the study
of major phenomena surrounding them”
(ACM/IEEE)

14. HCI – A Successful Product
• 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.

16. What we have learned today?
• What is HCI?
• Why we need it? Importance?
• Basics and Formal definition of HCI
