Abstract
It is desirable that social robots are able to communicate a range of emotional states in a manner that is universally understood by people. It is proposed that the Geneva Emotion Wheel (GEW) has great potential for use as a tool for evaluating the ability of robots to express affective content. Some of the factors that make the GEW advantageous over existing methods include: a reduction in the importance of word labels, incorporation of emotional intensity, and coverage of 'no emotion' states. To support future research using the GEW, a software suite developed for conducting robotics experiments using the GEW has been made available as an opensource tool to the community.
