Categories and subcategories

  • Discourse: Meaningful conversation between PwD and the robot
  • Statement: Statement either by the robot or the PwD. Can be a question or an answer.
    • E.g. “Hello Peter”, “How are you doing today?”
  • RobotSRA (Self-reflection Aid): Statement that seeks out information about the PwD, either for them to disclose it to the robot, or just think about it themselves.
    • E.g. “Are you feeling hungry?”, “How did the dinner make you feel?”, “Are you feeling tired?”
  • Disclosure: Meaningful information provided by the PwD
    • E.g. “I am feeling hungry”, “I did not eat dinner”, “I should drink water”, “I am feeling well today”

    • E.g. Lunch, dinner, hunger, thirst, tiredness, sleep etc.
  • Valence: The ”positivity” of the disclosure
