Interaction between User and Computer

Interaction between User and Computer

Human–computer interaction (HCI) involves the study, planning, design and uses of the interfaces between people (users) and computers.

HCI (human-computer interaction) is the study of how people interact with computers and to what extent computers are or are not developed for successful interaction with human beings.

HCI is a very broad discipline that encompasses different specialties with different concerns regarding computer development: computer science is concerned with the application design and engineering of the human interfaces; sociology and anthropology are concerned with the interactions between technology, work and organization and the way that human systems and technical systems mutually adapt to each other; ergonomics is concerned with the safety of computer systems and the safe limits of human cognition and sensation; psychology is concerned with the cognitive processes of humans and the behavior of users; linguistics is concerned with the development of human and machine languages and the relationship between the two.

  • There are no restrictions on redistribution or use;
  • The licensing conditions are usually intended to facilitate continued re-use and wide availability of the software, in both commercial and non-commercial contexts;
