Analysis of the Effect of Agent's Embodiment and Gaze Amount on Personality Perception

Abstract

In this study, we implemented a gaze model, based on Japanese gaze behavior analysis, on an eyeball manipulable robot and virtual agent. Then, we analyzed the effects of agent embodiment and change in gaze amount on the agent's personality perception with Japanese participants. The results suggested that it is possible to express extroversion and confidence in the agent by changing the agent's gaze amount regardless of the agent's embodiment. In addition, the levels of perceived extroversion as gaze amount increases differ depending on the embodiment of the agents. The virtual agent's perceived extroversion increased in proportion to increases in its gaze amount, whereas the robot's extroversion increased more slowly with increases in its gaze amount.
