Survey and Perspective on Social Emotions in Robotics
It addresses the need for more advanced emotional capabilities in robotics to enhance social interactions, but is incremental as it primarily reviews and synthesizes existing work.
This review paper surveys existing research on social emotions in robotics, summarizing findings from psychology and neuroscience, and discusses future directions for implementing these higher-level emotions in next-generation socially aware robots.
This study reviews research on social emotions in robotics. In robotics, the study of emotions has been pursued for a long time, including the study of their recognition, expression, and computational modeling of the basic mechanisms which underlie them. Research has advanced according to well-known psychological findings, such as category and dimension theories. Many studies have been based on these basic theories, addressing only basic emotions. However, social emotions, also referred to as higher-level emotions, have been studied in psychology. We believe that these higher-level emotions are worth pursuing in robotics for next-generation, socially aware robots. In this review paper, we summarize the findings on social emotions in psychology and neuroscience, along with a survey of the studies on social emotions in robotics that have been conducted to date. Thereafter, research directions toward the implementation of social emotions in robots are discussed.
