Nonverbal dating behaviors
Our findings reveal that the introvert participants are positively affected by backchanneling in robot’s head nodding behaviour, which results in substantial head nodding synchrony whereas the extravert participants are positively influenced by turn-taking in gaze behaviour, which leads to significant mutual gaze convergence.This study demonstrates that there is a relationship between robot’s nonverbal behaviour and human’s likability based on human’s personality.In Nass’s and Aly’s studies, they both showed that introvert participants prefer the interaction with introvert characteristics voices while the extravert participants prefer extravert characteristics more.These previous studies evinced that the robot’s behaviours that can express the characteristics of its personality and are compatible with human’s personality can facilitate higher likability toward the robot.However, for human-robot interaction, it is still unclear whether there is nonverbal behaviour compatibility between human and robot or not and it leaves following unanswered questions.Firstly, does specific means and strategy of robot’s nonverbal behaviour influences and enhances likability from human with different personality traits (Introvert and Extravert)?To explore the relationship between robot’s nonverbal behaviour and human likability based on human’s personality in human-robot interaction, we developed 2 robot’s behaviour strategies for NAO robot: Backchanneling strategy and Turn-taking strategy, focusing on robot’s gaze and head nodding behaviours.
It has been integrated in our living environments, for example, in school.
In this study, we then aim to investigate whether specific means (gaze or head nodding behaviour) and strategy (Backchanneling or Turn-taking) of robot’s nonverbal behaviour influences and enhances likability in human with specific personality (Introvert and Extravert).
In other words, is there any relationship between robot’s nonverbal behaviour and human’s likability based on human’s personality and whether it is really expressed through their interactional behaviours with the robot accordingly.
With Backchanneling strategy, the robot will always give responses via its gaze and head nodding as backchannelings to human.
When human initiates head nodding, the robot will nod as a response.
