An increasing number of applications for social robots focuses on learning and playing with children. One of the unanswered questions is what kind of social character a robot should have in order to positively engage children in a task. In this paper, we present a study on the effect of two different social characters of a robot (peer vs. tutor) on(More)
Since children (5-9 years old) are still developing their emotional and social skills, their social interactional behaviors in small groups might differ from adults' interactional behaviors. In order to develop a robot that is able to support children performing collaborative tasks in small groups, it is necessary to gain a better understanding of how(More)
This paper addresses the issue of how personality recognition can be helpful for sentiment analysis. We exploited the corpus for sentiment analysis released for the SEMEVAL 2013, we automatically annotated personality labels by means of an unsupervised system for personality recognition. We validated the automatic annotation on a small set of Twitter users,(More)
Imagine a room with toys scattered on the floor and a robot that is motivating a small group of children to tidy up. This scenario poses real-world challenges for the robot, e.g., the robot needs to navigate autonomously in a cluttered environment, it needs to classify and grasp objects, and it needs to interact with the children and adapt its behaviors to(More)
Minimal movements coupled with semantic free utterances could represent a solution for non-anthropomorphic robots to meaningfully communicate during child-robot interaction (cHRI). The research presented in this paper explores minimal nonverbal behavior to supply non-anthropomorphic robots with the communicative power necessary to engage as 'cooperative(More)
In this paper, we present ongoing research combining two technologies to support children's cooperative interaction: interactive playgrounds and robots. We propose that interactive playgrounds are vehicles for playful cooperation when robots are integrated into the system as cooperative co-players. We developed the Hatch 'em all game, wherein children are(More)
Not getting enough sleep is detrimental to our health and productivity, yet we have difficulty to maintain consistent bedtimes. Technological solutions to this problem mostly focus on detecting sleep patterns and providing feedback on them. We felt there was an opportunity for a perspective that concentrates on one's subjective experience. We propose(More)
Robots are becoming part of children's care, entertainment, education, social assistance and therapy. A steadily growing body of Human-Robot Interaction (HRI) research shows that child-robot interaction (CRI) holds promises to support children's development in novel ways. However, research has shown that technologies that do not take into account children's(More)
