What is HCI? CSE/ISE 323 Spring 2011 Tony Scarlatos
ACM SIGCHI Definition of HCI “Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them.”
An Interdisciplinary Field • Computer Science (application design and engineering of human interfaces) • Psychology (the application of theories of cognitive processes and the empirical analysis of user behavior) • Sociology and Anthropology (interactions between technology, work, and organization) • Industrial Design (interactive products)
Is HCI the same as Ergonomics? The word "Ergonomics" comes from two Greek words, "ergon" meaning work, and "nomos" meaning "laws." A typical ergonomics diagram for a computer workstation
International Ergonomics Association: “Ergonomics is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance.”
So what about Human Factors? • Human factors science is a multidisciplinary field incorporating contributions from psychology, engineering, industrial design, statistics, operations research and anthropometry. • The science of understanding the properties of human capability (Human Factors Science). • The application of this understanding to the design, development and deployment of systems and services (Human Factors Engineering). • The art of ensuring successful application of Human Factors Engineering to a program (sometimes referred to as Human Factors Integration). It can also be called ergonomics. • In general, a human factor is a physical or cognitive property of an individual or social behavior which is specific to humans and influences functioning of technological systems as well as human-environment equilibriums.

A New Term – User Experience (UX) • User eXperience (UX) is about how a person feels about using a system. User experience highlights the experiential, affective, meaningful and valuable aspects of human-computer interaction and product ownership, but it also includes a person’s perceptions of the practical aspects such as utility, ease of use and efficiency of the system. • International Organization for Standards (ISO): “a person's perceptions and responses that result from the use or anticipated use of a product, system or service.”
Why User Experience? Recent advances in mobile, ubiquitous, social, and tangible computing technologies have moved human-computer interaction into practically all areas of human activity. This has led to a shift away from usability engineering to a much richer scope of user experience, where user's feelings, motivations, and values are given as much, if not more, attention than efficiency, effectiveness and basic subjective satisfaction.
