Robot Emotive Display Systems and the Analogous Physical Features of Emotion

Abstract

Robots are currently utilized by various civilian and military agencies, and are becoming more common in human environments. These machines can vary in form and function, but require an interface supporting naturalistic social interactions. Emotion is a key component of social interaction that conveys states and action tendencies, and standard design protocol is necessary to guide the research and development of emotive display systems so that reliable implementations are supported. This work suggests a framework for conveying emotion based on the analogous physical features of emotive cues and their associations with the dimensions of emotion. Sound, kinesics, and color can be manipulated according to their speed, intensity, regularity, and extent to convey the emotive states of a robot. Combinations of cues can enhance human recognition accuracy of robot emotion, but further research is necessary to understand the extent of these interactions and establish each parameter space.
