The symmetry of partner modelling

Mirweis Sangin, Pierre Dillenbourg, Nicolas Nova, Gaëlle Molinari, Séverin Lemaignan

Collaborative learning has often been associated with the construction of a shared understanding of the situation at hand. The psycholinguistics mechanisms at work while establishing common grounds are the object of scientific controversy. We postulate tha ...

Children’s Peer Assessment and Self-disclosure in the Presence of an Educational Robot

Pierre Dillenbourg, Shruti Chandra, Ana Paiva, Séverin Lemaignan

Research in education has long established how children mutually influence and support each other's learning trajectories, eventually leading to the development and widespread use of learning methods based on peer activities. In order to explore children's ...

Building Successful Long Child-Robot Interactions in a Learning Context

Pierre Dillenbourg, Ana Paiva, Séverin Lemaignan, Alexis David Jacq, Fernando Garcia

The CoWriter activity involves a child in a rich and complex interaction where he has to teach handwriting to a robot. The robot must convince the child it needs his help and it actually learns from his lessons. To keep the child engaged, the robot must le ...

From Real-time Attention Assessment to “With-me-ness” in Human-Robot Interaction

Pierre Dillenbourg, Séverin Lemaignan, Alexis David Jacq, Fernando Garcia

Measuring ``how much the human is in the interaction'' -- the level of engagement -- is instrumental in building effective interactive robots. Engagement, however, is a complex, multi-faceted cognitive mechanism that is only indirectly observable. This art ...

Real-Time High-Accuracy 2D Localization with Structured Patterns

Francesco Mondada, Pierre Dillenbourg, Lukas Oliver Hostettler, Séverin Lemaignan, Ayberk Özgür

Building over algorithms previously developed for digital pens, this article introduces a novel 2D localization technique for mobile robots, based on simple printed patterns. This method combines high absolute accuracy (below 0.3mm), unlimited scalability, ...

Can a Child Feel Responsible for Another in the Presence of a Robot in a Collaborative Learning Activity?

Pierre Dillenbourg, Shruti Chandra, Ana Paiva, Séverin Lemaignan

In order to explore the impact of integrating a robot as a facilitator in a collaborative activity, we examined interpersonal distancing of children both with a human adult and a robot facilitator. Our scenario involves two children performing a collaborat ...

Ranger, an Example of Integration of Robotics into the Home Ecosystem

Francesco Mondada, David Mansolino, Julia Fink, Séverin Lemaignan

This paper presents the concept and an example of robject, a robotic entity embedded in an everyday object. Robjects use the affordance of the original object to ensure an efficient interaction and a high acceptance. The example of the ranger robot shows t ...

A review: Can robots reshape K-12 STEM education?

Francesco Mondada, Séverin Lemaignan, Mohammad Ehsanul Karim

Can robots in classroom reshape K-12 STEM education, and foster new ways of learning? To sketch an answer, this article reviews, side-by-side, existing literature on robot-based learning activities featuring mathematics and physics (purposefully putting as ...

Mutual Modelling in Robotics: Inspirations for the Next Steps

Pierre Dillenbourg, Séverin Lemaignan

Mutual modelling, the reciprocal ability to establish a mental model of the other, plays a fundamental role in human interactions. This complex cognitive skill is however difficult to fully apprehend as it encompasses multiple neuronal, psychological and s ...

You're Doing It Wrong! Studying Unexpected Behaviors in Child-Robot Interaction

Francesco Mondada, Pierre Dillenbourg, Julia Fink, Séverin Lemaignan

We present a study on the impact of unexpected robot behaviors on the perception of a robot by children and their subsequent engagement in a playful interaction based on a novel ”domino” task. We propose an original analysis methodology which blends behavi ...

When Children Teach a Robot to Write: An Autonomous Teachable Humanoid Which Uses Simulated Handwriting

Pierre Dillenbourg, Séverin Lemaignan, Deanna Hood

This article presents a novel robotic partner which children can teach handwriting. The system relies on the learning by teaching paradigm to build an interaction, so as to stimulate meta-cognition, empathy and increased self-esteem in the child user. We h ...

Human-Robot Interaction: Tackling the AI Challenges

Séverin Lemaignan

Human-Robot interaction is an area full of challenges for artificial intelligence: dynamic, partially unknown environments that are not originally designed for autonomous machines; a large variety of situations and objects to deal with, with possibly compl ...

Simulation and HRI -- Recent Perspectives with the MORSE Simulator

Séverin Lemaignan

Simulation in robotics is often a love-hate relationship: while simulators do save us a lot of time and effort compared to regular deployment of complex software architectures on complex hardware, simulators are also known to evade many (if not most) of th ...

A Few AI Challenges Raised while Developing an Architecture for Human-Robot Cooperative Task Achievement

Séverin Lemaignan

Over the last five years, and while developing an architecture for autonomous service robots in human environments, we have identified several key decisional issues that are to be tackled for a cognitive robot to share space and tasks with a human. We intr ...

Which Robot Behavior Can Motivate Children to Tidy up Their Toys? Design and Evaluation of "Ranger"

Francesco Mondada, Florian Christopher Vaussard, Pierre Dillenbourg, Philippe Rétornaz, Alain Berthoud, Julia Fink, Séverin Lemaignan

We present the design approach and evaluation of our proto- type called “Ranger”. Ranger is a robotic toy box that aims to motivate young children to tidy up their room. We evalu- ated Ranger in 14 families with 31 children (2-10 years) using the Wizard-of ...

The Cognitive Correlates of Anthropomorphism

Pierre Dillenbourg, Julia Fink, Séverin Lemaignan

While anthropomorphism in human-robot interaction is often discussed, it still appears to lack formal grounds. We recently proposed a first model of the dynamics of anthropomorphism that reflects the evolution of anthropomorphism in the human-robot interac ...
