Emotional Storytelling using Virtual and Robotic Agents [article]

Sandra Costa, Alberto Brunete, Byung-Chull Bae, Nikolaos Mavridis
2016 arXiv   pre-print
In order to create effective storytelling agents three fundamental questions must be answered: first, is a physically embodied agent preferable to a virtual agent or a voice-only narration?  ...  The results of two specially designed studies indicate that the physically embodied robot produces more attention to the listener as compared to a virtual embodiment, that a human voice is preferable over  ...  BACKGROUND Storytelling using Virtual Agents Several studies on emotionally expressive storytelling have been conducted using virtual agents.  ...
