What is HCI?

HCI involves the design, implementation and evaluation of interactive systems in the context of the user's task and work.‘

• Human-Computer Interaction is not just about a single user and a desktop computer.

• The user might be an individual, group of people, or a sequence of users dealing with a task.

• The computer might be a desktop computer, large-scale computer, embedded computer, process control system, . . .

• Interaction could be direct or indirect communication between the two.

• The term HCI is young and the discipline has its base in ergonomics (or human factors) and man-machine interaction ( Interface).

Who is involved in HCI?

Multi disciplinary involving:

In other words:

– Computer Science & Eng to be able to build the technology

– Psychology & cognitive science to give her knowledge of the user’s perceptual, cognitive & problem solving skills

– Ergonomics for the user physical capabilities

– Sociology to help understand the wider context of the interaction

– Graphic Design to produce an effective interface presentation.

Unfortunately cannot have all in only one person. But can identify and apply principles and guidelines from these disciplines that contribute to better system design.
