  2. Objective:

    • Designing one personality in an ECA to fit all kinds of human factors is quite hard.
    • Our goal is not to design two perfectly adequate personalities of ECAs, but to find principles for designing more or less extroverted agents, with the goal to improve the user-satisfaction.
  3. Agent Type: Wizard of Oz. 3D simple humanoid body

  4. Theme of conversation (domain): domain of studying digital media in the University of Bremen.

  5. Memo:

    • the results significantly show that users talk more and have less speech disfluency when interacting with the extroverted agent.

    • a difference in the mental models of computer experts versus non-computer experts

    • Extrovert speaking style: extrovert language converses less formally / taking the lead in a conversation is construed as a sign of an extroverted personality

    • extroverted agent having larger and faster movements in its nonverbal behavior style.

    • feedback signals, namely, the human expressions during the dialogues. We used both verbal modalities as the utterance “hmm”

    • agent’s competence, credibility, speaking style, behavior, etc., of the extroverted agent were scored higher than the introverted agent

    • users were more talkative while interacting with the extroverted agent

    • the mental models concerning ECAs of humans can be assumed to be different in various professional or cultural backgrounds

    • computer experts chose more simple words than non-computer experts did

    • the extroverted agent reduced users’ speech disfluency, manifested by hesitations, such as “um” or “uh”, in the utterance. Users in extroverted agent group spoke slower.

    • people prefer a personality which similar to themselves over different ones
