다국어 초록 (Multilingual Abstract)

In modern society, along with the infinite development of industry, robot technology has made remarkable progress, and at the same time, there have been cases where robots are used in various fields. Human-Robot Interaction (HRI) is becoming more important as robots are used in various fields. Therefore, there is a need for research on emotional communication of robots. The purpose of this study is to investigate the use of the social robot 's pupil as a communication medium between the social robot and the user. The purpose of this study is to investigate whether the emotional elements expressed by the robot's pupils have a positive effect on user consensus and acceptance formation through the process of structuring the pupil shape as a means of conveying emotions in robot communication. To understand this, we classify the basic emotions felt by humans and extract emotional words according to their emotional categories. Russell 's Circumflex model (1980) was applied as emotion word extraction and evaluation model. Experiments were conducted for the selection of emotional pupil prototypes. Based on the experimental results, pupil elements were derived and a pupil expression prototype was constructed. For the emotion classification, the relationship between the emotion corresponding to the evaluation model and the visual expression of the pupil was mapped, and then the preference of each pupil prototype type was investigated. As a result of the research, it was shown that the type of social robot 's pupil is reminiscent of a round shape, and most of the social robot' s pupils perceive the intention and intention to convey as intended.
This study investigated one of the physical elements that constitute a robot to draw empathy for emotional reaction in interaction with social robot. It also has significance by revealing the emotional influence of social robot's eyes on the emotional transmission and interaction of users.
