  1. Define rich interaction - how does it differ from conventional HCI?
    • more users considered
    • users are embodied
    • occurs in environmental context of rich representational artifacts
    • occurs in context of communication with other users
    • occurs in cultural/organisation context
  2. Give examples of Instructing, Conversing, Manipulation and Exploration
    • Instructing: user tells system what to do, by typing commands, selecting menu options, pressing keys or buttons, speaking commands
    • Conversing: user has dialogue with system; typing questions and/or responses, or uses speech input/output
    • Manipulation: user interacts with physical or virtual objects, e.g., holding, moving, opening, closing; object is a focus of attention
    • Exploration: user moves through physical or virtual environment
  3. Explain DM and name the 3 core direct manipulation principles
    Digital objects should allow interaction analogous to how physical objects are manipulated

    • -Continuous representation of objects and actions
    • -Physical actions instead of issuing commands with complex syntax
    • -Rapid reversible actions with immediate feedback on object of interest
  4. Define distributed cognition
  5. Explain an interaction from the point of view of dirtibuted cognition with its features - multiple people, artefacts, etc.
  6. describe features of situated cognition
    • process
    • triggers (immediate, temporal, sporadic, external event, environmental cue)
    • artefacts
    • placeholders (where you are in the program, like Program Counter)
