Introduction
Recent topics of research concern epigenetic approaches of the human development, development of motor imagery and brain computing in human children and development of infrared technology for measuring pain in preterm infants and neonates. I'm now mainly involved in image processing (binding OpenCV to Red and REBOL languages) and in the development of low-cost eye-tracking system.

PurposeChoosing the right tracheal tube for the right patient is a daily preoccupation for intensivists and emergency physicians. Tracheal tubes can generate severe complications, which are chiefly due to the pressures applied by the tube to the trachea. We designed a bench study to assess the frequency of pressure levels likely to cause tracheal i...

Monitoring vital signs of neonates can be harmful and lead to developmental troubles. Ballistocardiography, a contactless heart rate monitoring method, has the potential to reduce this monitoring pain. However, signal processing is uneasy due to noise, inherent physiological variability and artifacts (e.g. respiratory amplitude modulation and body...

Liars are caught in a paradox: they want to provide details to be credible but not so many they could be discovered being untruthful. The verifiability approach assumes that liars include fewer verifiable details, more unverifiable details (or a similar amount), and a lower proportion of verifiable details than truth-tellers. This meta-analysis inc...
Conference Paper
Ballistocardiography (BCG), a contactless heart rate monitoring method, has the potential to measure vital signs and reduce neonates' monitoring pain and discomfort. It uses an accelerometer on the mattress side. However, the bedding and bed frame nature may alter the propagation of the ejection force to the sensor, especially in case of viscous fo...
Conference Paper
Ballistocardiography (BCG), a contactless heart rate monitoring method, has the potential to measure vital signs and reduce neonates’ monitoring pain and discomfort. It uses an accelerometer on the mattress side. As the signal amplitude is very low, the front-end circuit needs a high amplifier gain and thus is very sensitive to baseline wander and...

Article
L’objectif de la présente étude est d’évaluer si les interfaces tactiles numériques peuvent favoriser l’expression de la créativité graphique. Cette question est posée à deux périodes du développement de la créativité : en classe de CP, où la créativité des enfants connaît un déclin, et en classe de CE2 où, au contraire, elle connaît un regain d’ac...
Article
It is widely accepted that motor imagery development during childhood may be due to refinement of internal models of action. At the same time, gradual improvement of predictive motor control in children may reflect an increasing ability to integrate the proprioceptive afferences with other sources of sensory information (especially vision). The cur...
Article
To which extent is motor imagery (MI) development, commonly observed between the ages of 5 and 9, related to the increasing ability to integrate proprioceptive afferences for the control of action? This question was addressed in a study evaluating MI performance of 108 children aged 5, 7 and 9 years old. A mental chronometry paradigm based on a wal...
Article
EnglishAndre Bullinger conceived sensorimotor development of the child as being deeply rooted in the many and complex interactions occurring between sensory flows and deep-tonic sensations. Integration of these two components gives rise to a proprioceptive function which he defined as a non-biological coordination that can be modified according to...

This paper presents an approach for action recognition performed by human using the joint angles from skeleton information. Unlike classical ap-proaches that focus on the body silhouette, our approach uses body joint angles estimated directly from time-series skeleton sequences captured by depth sen-sor. In this context, 3D joint locations of skele...

Different sort of people are interested in personal identity. Philosophers frequently ask what it takes to remain oneself. Caregivers imagine their patients' experience. But both philosophers and caregivers think from the armchair: they can only make assumptions about what it would be like to wake up with massive bodily changes. Patients with a loc...

Paralysis has many causes including trauma, stroke, infection, and autoimmune diseases. The primary damage can be manifested in the brain, spinal cord, spinal nerves, or the muscles themselves. Over the past years, most research devoted to paralysis has involved cell biology approaches (i.e. embryonic stem cells). Although such approaches represent...
Conference Paper
The problem of eye gaze tracking has been researched and developed for a long time. The most difficult problem in the non-intrusive system of eye gaze tracking is the problem of head movements. Some of existing methods have to use two cameras and an active infrared (IR) illumination to solve this problem. Otherwise, with a single camera, the user h...
Conference Paper
The problem of eye gaze tracking has been researched and developed for a long time. Most of them use intrusive techniques to estimate the gaze of a person. This paper presents a non-intrusive approach for eye gaze tracker in real time with a simple camera. To track the eye gaze we have to deal with three principle problems: detecting the eye, track...

A recent research revealed the capacity of the newborn to haptically detect, the weight of an object [12]. In this research, we tried to determine the means by which newborn infants, not having yet exploratory procedures, are able to treat this object property. We support the assumption that tactile perceptive capacities of the newborn infants deri...

Two alternative hypotheses can be used to explain how young children acquire the cardinal meaning of small-number words. The first stresses the role of counting and predicts better performance when the items are presented in succession. The second considers the role of subitizing and predicts better performance when the items are presented simultan...
Article
This article argues that the multimodal processing of sensorial flows is a biological property of organisms. Already effective at birth, the multimodal processing of flows organizes the infant's environment and unifies his/her perception, permitting the perception of multimodal but unified objects. The multimodal processing of sensorial flows is al...
