@inproceedings { ribeiro12, abstract = {This paper describes our approach on the development of the expression of emotions on a robot with constrained facial ex- pressions. We adapted principles and practices of animation from DisneyTMand other animators for robots, and applied them on the development of emotional expressions for the EMYS robot. Our work shows that applying animation prin- ciples to robots is beneficial for human understanding of the robots’ emotions.}, address = {Boston, USA}, booktitle = {Proceedings of the seventh annual ACM/IEEE international conference on Human-Robot Interaction}, keywords = {animation, emotions, facial expressions;Social Robotic Companions;}, pages = {383--390}, publisher = {ACM}, series = {HRI '12}, title = {The Illusion of Robotic Life: Principles and Practices of Animation for Robots}, year = {2012}, author = {Tiago Ribeiro and Ana Paiva} }
