As robotic technologies of varying shapes and forms continue to make their way into our everyday lives, the significance of a humanoid robot's ability to make a human interaction feel natural, engaging and entertaining becomes an area of keen interest in sociable robotics. In this paper, we present our findings on how affective feedback can be used to drive reinforcement learning in human-robot interactions...
Humanoid robots have this formidable advantage to possess a body quite similar in shape to humans. This body grants them, obviously, locomotion but also a medium to express emotions without even needing a face. In this paper we propose to study the effects of emotional gaits from our biped humanoid robot on the subjects' perception of the robot (recognition rate of the emotions, reaction time, anthropomorphism,...
This research explored whether robots can use modern speech synthesizers to convey emotion with their speech. We investigated the use of MARY, an open source speech synthesizer, to convey a robot's emotional intent to novice robot users. The first experiment indicated that participants were able to distinguish the intended emotions of anger, calm, fear, and sadness with success rates of 65.9%, 68...
This paper presents an exploratory study in which children with autism interact with ZECA (Zeno Engaging Children with Autism). ZECA is a humanoid robot with a face covered with a material allowing the display of varied facial expressions. The study investigates a novel scenario for robot-assisted play, to help promoting labelling of emotions by children with autism spectrum disorders (ASD). The study...
Studies about human interaction have shown that subtle changes in movement performance and body posture may improve people's acceptance in social groups. The same applies also to robots. However, most of the work has been done on faces and bio-inspired or humanoid robots, while still few works have focused on generic robot body movement to produce interesting interaction settings, which include emotion...
