ABSTRACT

The discipline of Human Factors and Ergonomics, since its inception more than 50 years ago, has been the leading force in designing machines for human use. HCI design is a specific case in Human Factors and Ergonomics, requiring the design of a system which is currently utilized by 1 billion people. No other system or machine has ever existed with the physical, social and cognitive complexity so widely utilized, as the computer. For this reason, HCI evolved some 20 years ago as a separate professional and scientific discipline.
