Psychological effects of educational-support robots using an emotional expression model

Abstract

With the growth of robot technology, robots that assist learning have attracted increasing attention. However, users tend to lose their interest in these educational-support robots. To solve this problem, human-agent interaction studies have proposed a model of emotional expressions. Nevertheless, this model, in which the agent expresses his/her emotions as autonomous emotions, has proved to be effective for interactions between agents and humans. Thus, this paper examines how psychological effect of robot which expresses the emotion by using the model of emotional expressions can prompt learners in a collaborative learning.

A proposal of model of emotional expressions for robot learning with human

“…However, when the X coordinate's absolute value is large, the angle of the coordinate point does not fluctuate much unless the Y coordinate's value is greatly changed. Therefore, the previous study's model [10] tends to always express the same emotion. Conversely, the proposed model in this paper uses two emotion vectors instead of two coordinate points.…”

“…A previous study [10] proposed a circumplex model that uses two coordinate points. Here, the x-and y-axes correspond to pleasure-displeasure and arousing-sleep, respectively.…”

“…Because an agent's sympathy has been demonstrated to improve student's motivation to learn [9], comparative model 1 uses two coordinate points to express emotions [10]. In this model, A(X A , Y A ) is defined as the correct coordinate point, representing a student's correct answer, and B(X B , Y B ) is defined as the incorrect coordinate point, representing a wrong answer.…”

Dynamic Affect-Based Motion Planning of a Humanoid Robot for Human-Robot Collaborative Assembly in Manufacturing

“…The state-of-the-art literature shows a significant number of robots that are enriched with affective abilities, such as Kismet [25], iCAT [26], Flobi [27], ERWIN [28], Kobian [29], NAO [30], Kamin [31], Ifbot [32], WE-3R III [33], etc., and more recently, the realistic robots Robokind [34] and Geminoid [35]. However, these robots are not proposed for HRC in assembly in manufacturing, and their suitability for HRC in assembly is also not tested.…”

“…However, these robots are not proposed for HRC in assembly in manufacturing, and their suitability for HRC in assembly is also not tested. Instead, state-of-the-art robots with affective abilities are used mainly for driver's guidance in transportation [31], educational supports [32], social services [36,37], health care training [38], etc. Thus, applications of robots with affective expressions to HRC in assembly have not received much attention yet, except some preliminary initiatives [39,40].…”
