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[?]
  • keystroke-level modelling (KLM)[?]
  • cognitive walkthrough[?]
  • cognitive dimensions of notation[?]
• Technologies
  • GUI toolkits[?]
  • software architecture[?]
  • input and output devices[?]
  • computer vision
  • speech recognition and natural language processing
• Computer accessibility[?]
• The Internet
• Computer-supported collaborative work[?]
• Software agents[?] and intelligent interfaces[?]
• Information retrieval
• Information visualization
• Virtual reality
• Ubiquitous computing
• Wearable computers
