Human-computer interaction

Human-computer interaction (HCI) is the study of interactions between people and computers. It is an interdisciplinary field, relating computer science, psychology, cognitive science, [human factors engineering]? (ergonomics), sociology, library and information science, and other fields. One of the goals of the field is to make computers more user-friendly.

Although much of the practical work in HCI revolves around the design of graphical user interfaces, HCI is concerned with a number of topics, including

• Interface design methods
  • [/user-centered design]?
  • [/participatory design]?
  • [/value-sensitive design]?
  • [/rapid prototyping]?
  • [/iterative design]?
• Usability testing
  • [/user testing]?
  • [/heuristic evaluation]?
• Technologies
  • [GUI toolkit]?s
  • [/software architecture]?
  • [/input and output devices]?
  • computer vision
  • [speech recognition]? and natural language processing
• [Computer accessibility]?
• The Internet
• [Computer-supported collaborative work]?
• [Software agent]?s and [[\intelligent interface]]s
• Information retrieval
• [Information visualization]?
• Virtual reality
• Ubiquitous computing
• Wearable computers
