The study of bridge between them, which includes
 Observation of interactions between people &
computers
 Analysis of the involved interactions

technology that people will want to use, will be able to use,
and will find effective when used.” (2002)

4. Why HCI?
 Now, computers are cheap and used by non-

noticed the importance of making computers

6. History of HCI
Below is the story of how HCI transformed from a specialty
area to a multifaceted community of tech professionals. The
field has come a long way since the 1980s — evolving from a
single focus on scientific testing to the complex role of
explaining and generating new designs.
Desktops & mental models(1980s— 1990s)
Collaboration & communication(1990s— early 2000s)
Self-expression, social change(mid 2000s — 2010s)

7. HCI Scope
•Use & Context: Find application areas for
computers
•Human : Study psychological & physiological
aspects e.g., study how a user learns to use a
new product, study human typing speed
• Computer: Hardware & software
e.g., input & output devices,
offered
speed,
interaction styles, computer graphics
implementation &•Development: Design,
evaluation
