In this paper we describe how a robot may benefit from active learning in a human-robot tutelage setting. Rather than passively absorbing conceptual knowledge, the robot learner actively tries to influence the human teacher in order to improve its learning experience. We compare the performance of agents that employ this strategy in simulation to a robot that interacts with a human teacher. It was...
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.
This video is about a new kind of robotic head. Through back-projection of a computer generated video into a half-translucent mask, the LightHead robotic head has many advantages compared to tradition mechatronic robotic faces. These advantages are most notably the versatility and ease of controlling facial expressions and creating new faces, the total weight and the low costs. By mounting the head...
Reading gaze direction is important in human-robot interactions as it supports, among others, joint attention and non-linguistic interaction. While most previous work focuses on implementing gaze direction reading on the robot, little is known about how the human partner in a human-robot interaction is able to read gaze direction from a robot. The purpose of this paper is twofold: (1) to introduce...
