An evaluation of robotic facial expressions for the humanoid social robot Joey

Abstract

The Institute for Information Systems of FHNW School of Business has various social robots at hand, among them Joey, a robot equipped with a rendered face that can display a wide range of emotions. This work aimed at designing and evaluating three different design sets of facial expressions by collecting data from potential robot interaction partners. The main aim was to investigate which facial features express the intended emotions best and how people perceive these social robot facial expressions. Finding a balance between expressiveness, likeability and suitability was the main challenge.
