All computer systems, single user or multi-user, interact with the work-groups and organizations in which they are used.

  • We need to understand normal human-human communication:
    • face-to-face communication involves eyes, face and body
    • conversation can be analyzed to establish its detailed structure.
  • This can then be applied to text-based conversation, which has:
    • reduced feedback for confirmation
    • less context to disambiguate utterances
    • slower pace of interaction
    but is more easily reviewed.
  • Group working is more complex than that of a single person:
    • it is influenced by the physical environment
    • experiments are more difficult to control and record
    • field studies must take into account the social situation.
