Abstract

This study verifies the effectiveness of the robotic emotional expressions developed using non-verbal languages. An emotional robot known as "Mung" was developed by applying the nonverbal expressions of bruises (blue or dark blue) and complexions (red or pink) using full color LEDs, to express robotic emotions. With these emotional expressions, Mung functioned as a language purifier by responding to humans' use of language emotionally. In order to evaluate emotional expressions used in Mung, an experiment was performed to compare the robotic emotions using a verbal language with those using non-verbal languages. A 2x2 between-groups factorial design was used for this experiment. The between-groups factors were expression type and emotion type. According to the results of a post-experiment survey, emotional expressions through bruises and complexion are as effective as speech for the delivery of robotic emotions. This result emphasizes the effectiveness of the developed robotic emotional expressions.
