@inproceedings { ribeiro11, abstract = {Facing the challenge of accurately expressing emotions with robots and characters with limited expressive capabilities, we developed an abstraction model for generating emotional expressions based on the atomic features that enable human beings to recognize emotions in other humans' faces. The model is also augmented by animation theory from movies and puppetry. A small evaluation of the expressions showed that some expressions were well recognized, in particular Anger and Sadness.}, address = {Eindhoven, The Netherlands}, booktitle = {Proceedings of the 11th International Conference on Intelligent Virtual Agents}, keywords = {LIREC;Affective Computing;Social Robotic Companions;}, month = {September}, pages = {466-467}, publisher = {Springer Berlin / Heidelberg}, series = {Lecture Notes in Computer Science}, title = {Expressing Emotions on Robotic Companions with Limited Facial Expression Capabilities}, volume = {6895/2011}, year = {2011}, author = {Tiago Ribeiro and Iolanda Leite and Jan Kedzierski and Adam Oleksy and Ana Paiva} }
