Interactive devices for faster access to information: navigation system for digital documents
2008
This article presents a step towards the inclusion of a preview control with established tactile interactive devices, such as the computer mouse and touch pad. It describes the origins of the device and its likely advantages in terms of ease of use and faster data retrieval as, for example, when a page previously consulted needs to be accessed again. The article limits itself to the contribution made by the device towards the consultation of digital documents, in particular on Internet sites. The device presented below makes it possible to leaf through a whole digital document from one and the same screen without mouse clicks. It can be used directly, by means of a command integrated into t…
Documents numériques : vers de nouveaux dispositifs d'interaction
2005
5 pages, publication des communications sur le site de la conférence; National audience; Actuellement les modes d'interaction avec les documents numériques visent à diminuer les contraintes d'espace et de temps avec notamment des dispositifs d'informations locales et une capacité de consultation étendue depuis un point central. On retrouve en cela les résultats d'études plus anciennes en ergonomie sur les tableaux de contrôle de processus (trafic ferroviaire, centrales nucléaires, tableaux de contrôles d'usines chimiques etc.) Une deuxième tendance, plus difficile à mettre en œuvre, consiste à permettre plusieurs types de présentation d'un document, que l'utilisateur peut adapter en fonctio…

Our problematic concerns the links between logic and topoï, semantics and topoï and finally between logic and semantics. The work therefore consists in highlighting the durability of the notion of topos, its evolution and its integration in logic, in semantics and even in computer science. From then on, topoi, logic and semantics are the three facets of this problematic. The purpose of this thesis is to present the history of topoi, to identify their linguistic properties. It also shows that this notion is present in all linguistic approaches and that semantics is the unifying axis of all linguistic research.It is not our intention to give a new definition, but we have tried to su…
Extension des méthodes de géométrie algorithmique aux structures fractales
2013
Defining shapes by iteration allows us to generate new structures with specific properties (roughness,lacunarity), which cannot be achieved with classic modelling.For developing an iterative modeller to design fractals described by a BCIFS, we developed a set oftools and algorithms that permits one to evaluate, to characterize and to analyse different geometricproperties (localisation, convex hull, volume, fractal dimension) of fractals. We identified properties ofstandard CAD operations (intersection, union, offset, . . . ) allowing us to approximate them for fractalsand also to optimize these approximation algorithms.In some cases, it is possible to construct a CIFS with generalised HUTCH…
Dispositif de pointage pour ordinateur : souris cartographique.

N° publication pour les reproductions : 2 886 425 N° d'enregistrement national : 05 05250 Description en ligne : http://www.wipo.int/pctdb/fr/ia.jsp?ia=FR2006%2F001201&IA=FR2006001201&DISPLAY=DESC; La présente invention concerne un dispositif de pointage manuel pour ordinateur et autres terminaux électroniques, tel qu'une souris ou un pavé tactile par exemple, comportant un corps principal monté sur une base remarquable en ce qu'il comporte des moyens de suspension reliant le corps principal à la base, associés à au moins un capteur de déplacement mesurant le degré d' enfoncement vertical du corps principal, relativement à la base et à sa position initiale, afin d'activer une fonction de pr…
Pitch tilt rendering for an 8-DOF driving simulator
2015
International audience; Tilt coordination technique is used for reproducing a sustained linear acceleration in driving simulation by tilting the simulator cabin. Thus a part of gravity is interpreted as a horizontal acceleration. Between the slow rotational motion limited by the rotational perception threshold of semi-circular canals of vestibular system and the fast change of acceleration to render, the design of coupling motions of rotation and translation plays a critical role in the realism of driving simulator. We present here an experiment focusing on longitudinal accelerations rendering with pitch tilt coordination technique. Eight drivers experienced the same accelerations and decel…
Usages des technologies par les élèves professeurs : analyse à partir de questionnaires
2005
This article studies the appropriation and the uses of technologies by French student teachers. The methodology used is based on the analysis of answers to questionnaires submitted to the trainees of four “instituts universitaires de formation des maîtres” (teacher training schools). The results obtained tend to prove that outside the classroom trainee teachers are today well equipped and really competent as far as personal and professional uses of technologies are concerned. However, it appears that these skills are not taken advantage of in the presence of the pupils.
