Refined human-robot interaction through retro-projected robotic heads

摘要

We present an overview of the LightHead robot and its retro-projected face, followed by opportunities for this technology to push the state-of-the-art in HRI. Through comparison with existing robot head technologies, we show how retro-projected faces can provide a means to display human social-emotional behaviours including subtle social cues not achievable with other robotic heads.
