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.

Infantile spasms are a severe epileptic syndrome characterized by short muscular contractions lasting from 0.5 to 2 seconds. They are often misdiagnosed due to their atypical presentation, and treatment is frequently delayed, leading to stagnation or regression in psychomotor development and significant cognitive and motor sequelae. One promising a...
Dans la littérature internationale, le taux de croissance de la face de l’enfant 7 ans reste largement méconnu. Classiquement seules les mesures radiographiques sont utilisées. Nous avons développé un logiciel autorisant le calcul des différentes dimensions faciales, en utilisant des photographies d’enfants de moins de 7 ans, à partir de 312 photog...
This case-control study uses computer vision and artificial intelligence to develop a screening tool for detecting spinal muscular atrophy in infants.
In line with the progressive development of digital technologies, this theoretical article is about the conception of a digital twin - based assistant to increase the serenity of the journey of the occupants of a connected car, automated or not. Its main functions are (i) to manage the Human (driver and/or passenger) - Machine (vehicle) Interaction...
Changes in lymphocyte production patterns occurring across human ontogeny remain poorly defined. In this study, we demonstrate that human lymphopoiesis is supported by three waves of embryonic, fetal, and postnatal multi-lymphoid progenitors (MLPs) differing in CD7 and CD10 expression and their output of CD127-/+ early lymphoid progenitors (ELPs)....

A Digital Twin is a digital description of a physical entity (object, system, living beings...) that is implemented with a specific device or user database and real-time updated and that can be used to simulate Human-Machine Interaction through machine learning and reasoning to help decision-making. This article is about a "Franco-Taiwanese Researc...
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...
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...
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...

En une dizaine d’années, l’apparition de nouvelles techniques, des puces à ADN au séquençage à haut débit ainsi que la découverte de concepts novateurs comme les ARN non codants ou les régulations épigénétiques ont révolutionné notre compréhension du développement. L’épigénomique, discipline qui étudie l’influence des modifications environnementale...
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...
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...
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...
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...
André Bullinger offre une lecture originale du développement sensorimoteur de l’enfant dans laquelle les interactions entre stimulations sensorielles et sensations toniques profondes occupent une place centrale. L’intégration entre sensibilité profonde et signaux issus des flux sensoriels permet de constituer la fonction proprioceptive, c’est-à-dir...
Socially Assistive Robots (SAR) may help improve care delivery at home for older adults with cognitive impairment and reduce the burden of informal caregivers. Examining the views of these stakeholders on SAR is fundamental in order to conceive acceptable and useful SAR for dementia care. This study investigated SAR acceptance among three groups of...
An infant-controlled tactile habituation without visual control procedure was used to evaluate the ability of 32 late-preterm neonates (mean gestational age: 34 weeks) and 32 early-term neonates (mean gestational age: 38 weeks) to actively explore with hands objects varying in texture (smooth, granular). Holding time and Hand Pressure Frequency (HP...
Les travaux en neurosciences ont profondément bouleversé l’image que nous avons du nouveau-né humain. L’idée d’un nouveau-né réflexe, peu corticalisé, a progressivement laissé place à un nouveau-né beaucoup plus compétent qu’on le croyait. Dans cette contribution, nous présenterons brièvement les grandes avancées de la recherche qui, dans le cadre...
In this paper, we propose a method for event recognition from thermal signature based 1-D signal. We use the non-redundant temporal Local Binary Pattern NRTLBP as a descriptor of the Pat-tern Of Interest (POI) signal. The original signal is extracted directly from local patch in region of interest. We introduce the wavelet decom-position as a pre-p...

Résumé Les différentes hypothèses théoriques qui ont été développées pour rendre compte de l’état initial de la cognition chez le nouveau-né, se sont toutes heurtées à la difficulté de comprendre la nature des contraintes qui orientent le développement et à la difficile explication du passage entre le biologique et le psychologique. Dans cet articl...
In this paper, we introduce our theoretical approach of Prospective Cognitive Ergonomics, our methodology and the results obtained through Homo Textilus, a project for designing what might be Smart Clothes, the future of interactions between people and their digital clothes. For collecting data, we used different kinds of inquiries (questionnaires,...
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...

INTRODUCTION Les mouvements oculaires sont de plus en plus utilisés dans les applications IHM (Interface Humain-Machine). Dans cet article, nous présentons notre système de commande qui associe 5 mouvements spécifiques des yeux : comme le clignement (ou la fermeture des yeux) et les fixations oculaires sur 4 régions (haut, bas, droite, gauche). Afi...
Eye-movements are increasingly employed to study usability issues in HCI (Human-Computer Interacetion) contexts. In this paper we introduce our appearance-based eye control system which utilizes 5 specific eye movements, such as closed-eye movement and eye movements with gaze fixation at the positions (up, down, right, left) for HCI applications. I...
By defining Know-How and considering the collection of relevant data, we provide a computational cognitive model that is based on the problem-solving and task-analysis literature. The model is of help for the conception of an automatic assessment system of Skills acquisition related to Know-How. The platform we are building is implementing the meth...
Solving any task involves thinking-to-gestures processes: unobservable mental superordinate goals to primitive hand movements acting on objects as trajectory data. The question is how to evaluate know-how taking into account both decision-making and dexterity. From the Cogni-tive Science literature and considering the col-lection of relevant data,...

This paper presents a review of motor imagery research in children. After a presentation of the main experimental paradigms used to study motor imagery ability, we expose a set of results concerning the emergence and the development of motor imagery in children that clearly reveals that this capacity would appear around 5-7 years and then would con...
Two of the challenges in appearance-based gaze tracking are: 1) prediction accuracy, 2) the efficiency of calibration process, which can be considered as the collection and analysis phase of labelled and unlabelled eye data. In this paper, we introduce an appearance-based gaze tracking model with a rapid calibration. First we propose to concatenate...
This study was conducted to compare how newborns of depressed mothers and newborns of nondepressed mothers gather tactile information about texture. Spontaneous manual activity on objects with a smooth or rough texture was recorded in 20 newborns born of mothers with a high risk of depression or a low risk of depression. An important result of the...
In this paper, we present a unified framework for the analysis of video databases by using Markov spatio-temporal random walks on graph. The proposed framework provides an efficient approach for clustering, data organization, dimension reduction and recognition. The aim of our work is to develop a vision-based approach for human behaviour recogniti...
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...
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...
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...
In the present study we compare the kinaesthetic and visual perception of the vertical and horizontal orientations (subjective vertical and subjective horizontal) to determine whether the perception of cardinal orientations is amodal or modality-specific. The influence of methodological factors on the accuracy of perception is also investigated by...
The modeling and simulation of a realistic nervous tissue are difficult because of the number of implied cell types (neuronal and glial), the topology of the networks, and the various heterogeneous molecular mechanisms. The MTIP (Mathematical Theory of Integrative Physiology) is used as a new modeling approach based on a representation in terms of...
A total of 80 children (40 5-year-olds and 40 7-year-olds) took part in an experiment to evaluate their capacity to mentally evoke a motor image of their own displacement. Using a chronometry paradigm, movement duration was compared in a task where children were asked to move in order to take a puppet back to its home (actual) and to think about th...
Generalized Galois lattices formalism for computing contextual categorization allows metrics to evaluate complexity and efficiency as well as methods for simplifying or complicating the external object at hand. Such methods are adapted for virtual environments and augmented reality devices for which it is simple to change the distribution of featur...
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...

The Hierarchical Segmentation Theory is about how Human operators process objects, events and actions through cognitive processes that start from segmentation external inputs to decision making by the use of the mathematical formalism developed as Generalized Galois Lattices Air Control Interfaces are computed on line for determining the attentiona...
Neuronal group selection theory (NGST) proposals [Edelman, G. M. (1992). Biologie de la conscience. Paris: Odile Jacob] focusing on variability are used to aid the understanding of the close relation existing at birth between cognitive endowments and haptic manual functioning. We report a series of experiments providing evidence for a manual activi...

This work investigated the accuracy of the perception of the main orientations (i.e., vertical and horizontal orientations) with the kinesthetic modality--a modality not previously used in this field of research. To further dissociate the influence of the postural and physical verticals, two body positions were explored (supine and upright). Twenty...
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...
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...
Haptic texture perception was investigated in 3-day-old infants. Following a habituation sequence with a smooth or granular object, babies received a haptic test during which they held either the familiar or a new textured object. Two dependent measures were recorded: (1) Holding time was used to assess habituation as well as reaction to novelty an...
We investigated neonates' capacity to haptically compare objects varying in texture property. Right-hand manual activity, assessed by holding time and hand-pressure frequency, was recorded for objects in the presence (test period) or absence (pretest and post-test periods) of an object simultaneously held in the left hand. Thirty-two babies were as...
The research evaluated 10-month-old infants' capacity to regulate their catching behavior according to the solidity principle as defined by Spelke. Twelve infants were observed in three conditions in which babies had to reach for an object placed behind an open box. In a first condition, the object was smaller than the box : It could be freely disp...
