Translating Head Motion into Attention - Towards Processing of Student’s Body-Language

Pierre Dillenbourg, Mirko Raca, Lukasz Kidzinski

Evidence has shown that student's attention is a crucial factor for engagement and learning gain. Although it can be accurately assessed ad-hoc by an experienced teacher, continuous contact with all students in a large class is difficult to maintain and re ...

Camera-based estimation of student's attention in class

Mirko Raca

Two essential elements of classroom lecturing are the teacher and the students. This human core can easily be lost in the overwhelming list of technological supplements aimed at improving the teaching/learning experience. We start from the question of whet ...

Holistic Analysis of the Classroom

Pierre Dillenbourg, Mirko Raca

Should we judge the quality of the class by the grades the students and teacher get at the end of the semester or how the group collaborated during the semester towards acquiring new knowledge? Up until recently, the later approach was all too inaccessible ...

Sleepers’ lag - study on motion and attention

Pierre Dillenbourg, Mirko Raca, Roland John Tormey

Human body-language is one of the richest and most obscure sources of information in inter-personal communication which we aim to re-introduce into the classroom’s ecosystem. In this paper we present our observations of student-to-student influence and mea ...

Tracking Multiple Players using a Single Camera

Pascal Fua, François Fleuret, Horesh Beny Ben Shitrit, Mirko Raca

It has been shown that multi-people tracking could be successfullly formulated as a Linear Program to process the output of multiple fixed and synchronized cameras with overlapping fields of view. In this paper, we extend this approach to the more challeng ...

System for Assessing Classroom Attention

Pierre Dillenbourg, Mirko Raca

In this paper we give a preview of our system for automatically evaluating attention in the classroom. We demonstrate our current behaviour metrics and preliminary observations on how they reflect the reactions of people to the given lecture. We also intro ...

Long Term Real Trajectory Reuse Through Region Goal Satisfaction

Ronan Boulic, Daniel Thalmann, Pascal Fua, Junghyun Ahn, Stéphane Gobron, Quentin Silvestre, Horesh Beny Ben Shitrit, Mirko Raca

This paper is motivated by the objective of improving the realism of real-time simulated crowds by reducing short term collision avoidance through long term anticipation of pedestrian trajectories. For this aim, we choose to reuse outdoor pedestrian trajec ...
