Neuroevolution of Actively Controlled Virtual Characters - An Experiment for an Eight-Legged Character
2018
Physics-based character animation offers an attractive alternative for traditional animations. However, it is often strenuous for a physics-based approach to incorporate active user control of different characters. In this paper, a neuroevolutionary approach is proposed using HyperNEAT to combine individually trained neural controllers to form a control strategy for a simulated eight-legged character, which is a previously untested character morphology for this algorithm. It is aimed to evaluate the robustness and responsiveness of the control strategy that changes the controllers based on simulated user inputs. The experiment result shows that HyperNEAT is able to evolve long walking contr…
How not to give up on train travel when you are deaf ?
2015
TRANSED 2015 - 14th International Conference on Mobility and Transport for Elderly and Disabled Persons, LISBONNE, PORTUGAL, 28-/07/2015 - 31/07/2015; The SUrDyn project aims at the design of an innovative visual information system, dedicated to travelers who cannot hear or understand audio disrupted announcements (e.g. cancellation, delay...) when they are in train stations. It is based on two previously developed systems: the Jade signer avatar, which informs travelers in French Signs Language, and an animated graphics translation. The objective is to combine these two approaches, in an optimal manner. We proposed a comprehension task to 159 participants divided in three groups: 53 deaf p…
Assessment of diaphragm and lung ultrasound interest as a diagnostic and monitoring tool in acute respiratory diseases by the physiotherapist in crit…
2021
Thoracic ultrasound is a non-invasive, ionization-free and easily available tool at the bedside of the critical care patient. The aim of this thesis is to assess the lung and diaphragm ultrasound interest in the diagnosis and monitoring of the acute pulmonary disorders by the critical care physiotherapist.Our narrative review showed a high diagnostic accuracy of lung ultrasound to diagnose acute pulmonary disorders commonly encountered by the physiotherapist. The review of the lung ultrasound semiology allowed us to propose a chest physiotherapy strategy depending the ultrasound findings in the patients. Our multicenter clinical trial enrolled 151 ICU patients and highlighted the high impac…
Computer Animation to teach interpolation
2019
<div data-canvas-width="460.953206963072">Aunque las asignaturas de matemáticas son un tema básico en los estudios de una ingeniería, a menudo son considerados por los estudiantes como una asignatura difícil. En este trabajo presentamos una experiencia de aprendizaje basada en la animación por ordenador mediante el uso de la modelización matemática.

What animated illustrations conditions can improve technical document comprehension in young students? Format, signaling and control of the presentat…
2005
We study the comprehension of a multimedia technical document about gear functioning by young pupils. The research is focused on the effect of three factors on the construction of a mental model: illustration format (animated versus static) signaling cues (presence versus absence) learner-control of information delivery (three rhythms of presentation: speed, slow and self-controlled). The experimental procedure, conducted with 123 children, follows three phases: pre-test, individual passation of the lesson, comprehension test, delayed post-test. The goal of the pre-test is the evaluation of prior knowledge about gears, but also the control of spatial and verbal working memory aptitude and r…
L'action culturelle mise à nu par ses métiers (1788-1988)
2009
Cultural development has been the object of a number of studies, especially in its relations with cultural policy -or policies- or even through the theoretical study and implementation of cultural action, one of its preferred functions. Within these two fields of research, neither occupational sociologists nor scientists working in the area of information and communication have ever singled out cultural actors as a professional group for the object of a study. The current research intends to explore this issue of the professionality of cultural actors, particularly in so far as concerns their contribution to cultural development. After having stated that these practitioners belong to a grou…
Continuous hand openness detection using a Kinect-like device
2014
This paper presents a novel method to reproduce in real time the opening and closing gestures of a human hand, animating a three-dimensional model of it. In other works, this result can be achieved by mapping a set of significant points of a real hand on the corresponding points of the model to animate. We propose an alternative way to produce the same effect without mapping points, but using a level-based estimation of the degree of opening of the hand. The experiments have been executed using Microsoft KinectTM, but the method would work on any other Kinect-like devices (as defined herein). The results obtained are particularly encouraging and demonstrate real-time performance of the syst…
An Emotional Talking Head for a Humoristic Chatbot
2011
The interest about enhancing the interface usability of applications and entertainment platforms has increased in last years. The research in human-computer interaction on conversational agents, named also chatbots, and natural language dialogue systems equipped with audio-video interfaces has grown as well. One of the most pursued goals is to enhance the realness of interaction of such systems. For this reason they are provided with catchy interfaces using humanlike avatars capable to adapt their behavior according to the conversation content. This kind of agents can vocally interact with users by using Automatic Speech Recognition (ASR) and Text To Speech (TTS) systems; besides they can c…
Inverse procedural modeling of 3D models for virtual worlds
2016
This course presents a collection of state-of-the-art approaches for modeling and editing of 3D models for virtual worlds, simulations, and entertainment, in addition to real-world applications. The first contribution of this course is a coherent review of inverse procedural modeling (IPM) (i.e., proceduralization of provided 3D content). We describe different formulations of the problem as well as solutions based on those formulations. We show that although the IPM framework seems under-constrained, the state-of-the-art solutions actually use simple analogies to convert the problem into a set of fundamental computer science problems, which are then solved by corresponding algorithms or opt…
Innovative visual design to assure information for all in transportation
2014
ICAP 2014, 28th International Congress of Applied Psychology, PARIS, FRANCE, 08-/07/2014 - 13/07/2014; This research aims to propose alternative visual design of audio railway disruption announcements in order at reducing handicap situations encountered by travelers who can't hear or understand oral messages (deaf, hearing-impaired or foreign people). Five announcements were translated into two visual modes: in French sign language (with a sign language avatar named Jade) and in animated graphical designs. Different combinations were tested in order to find the better compromise between spatial and temporal organization for the both visual messages. For spatial parameter, messages were eith…
