Abstract

In greeting encounters, first impressions of personality and attitude are quickly formed and might determine important relational decisions, such as the likelihood and frequency of subsequent encounters. An anthropomorphic user interface is not immune to these judgments, specifically when exhibiting social interaction skills in public spaces. A favorable impression may help engaging users in interaction and attaining acceptance for long-term interactions. We present three studies implementing a model of first impressions for initiating user interactions with an anthropomorphic museum guide agent with socio-relational skills. We focus on nonverbal behavior exhibiting personality and interpersonal attitude. In two laboratory studies, we demonstrate that impressions of an agent's personality are quickly formed based on proximity, whereas interpersonal attitude is conveyed through smile and gaze. We also found that interpersonal attitude has greater impact than personality on the user's decision to spend time with the agent. These findings are then applied to a museum guide agent exhibited at the Boston Museum of Science. In this field study, we show that employing our model increases the number of visitors engaging in interaction.

  • It is possible to convey personality in embodied, robot-based, and voice-based chatbots using body language and nonverbal cues such as voice pitch and speed, gaze, proximity, and gestures.

    “There is a growing body of literature suggesting that it is possible to convey personality in embodied, robot-based, and voice-based chatbots using body language and nonverbal cues, such as voice pitch and speed [23,58], gaze [22], proximity [24], and gestures [20,59].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
