Definition

  • Human-computer interaction (HCI) is the study and the design of interaction between people and computers.
  • 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. [http://sigchi.org/cdg/cdg2.html (Hewett et al., 2004).
  • Design methodologies in HCI aim to create user interfaces that are usable, i.e. that can be operated with ease and efficiency. However, an even more basic requirement is cognitive usability, ie. that the user interface be useful allowing the user to complete relevant tasks within a task environment.

  1. User needs analysis
    • Define the analysis framwork and methodology
    • Define contents and concepts
    • Aquire and categorize mental representations
  2. Define the interface "language"
  3. Prototype creation
  4. Usability and cognitive ergonomics testing
