3. What is HCI?

* Human Computer interaction (HCI) is characterized as a dialogue or interchange between

the human and the computer

+ Because the output of one serves as the input for the other in an exchange of actions and

intentions.

+ HCl is the study of interaction between people (users) and computers.
+ Human Computer Interaction is concerned with the design, evaluation and implementation

of interactive computing systems for human use and with the study of major phenomena
surrounding them.

4. HCI is an Interdisciplinary field

5. Why HCP

+ In the past, computers were expensive & used by technical people only.

+ Now, computers are cheap and used by non-technical people (different
backgrounds, needs, knowledge, skills)

* Computer and software manufacturers have noticed the importance of making

computers “user-friendly”: easy to use, save people time, etc.

6. Questionnaire's about HCI

HCI tackles questions concerning how people interact with computers
v Are computers intuitive or complicated?
V Are computers rewarding or frustrating?
Y How can computers be made accessible to everybody?
(e.g. Different physical abilities, different languages etc.)
Ÿ To what level can computer interaction be standardized?
v Are computers “user-friendly”?

Y What does it mean to be “user-friendly”?

aspects
e.g., study how a user learns to use a
new product, study human typing speed

Computer: Hardware & software offered
e.g., input & output devices, speed,
interaction styles, computer graphics
Development: Design, implementation & evaluation

9. Components of HCI

* The goal of HCI is to improve the interaction between users and computers by

making computers more user-friendly and receptive to the user's needs.

10. Component's of HCI

Human:
Individual user, a group of users working together, a
sequence of users in ar organization

Computer:

Desktop computer, large-scale computer system, Pocket
PC, embedded system (e.g., photocopier, microwave oven),
software (e.g., search engine, word processor)

User interface:
Parts of the computer that the user contacts with

Interaction:

Usually involve a dialog with feedback & control throughout
performing a task (e.g., user invokes “print” command and
then interface replies with a dialog box)
