Le web de demain BIBAFull-Text 1-5
  Vincent Quint
Web technologies change very rapidly. Even if the latest developments are not yet visible in our day-to-day use, founding technologies of tomorrow's Web can already be identified. The XML revolution opens the door to new perspectives, specifically for presenting information and for interacting with Web applications and services. This article analyzes the most recent work related to Web multimedia, support for different devices, new interaction modes, and some other trends that will significantly change the way we use the Web.
Le rôle fondamental du système d'interaction dans une installation de réalité virtuelle BIBAFull-Text 7-13
  Alain Grumbach
The aim of this paper is to assess the basic role of the interaction system within a virtual reality application. Starting with an introduction to our sense of virtual reality, we put the stress on the interaction between the human operator and the virtual world. After an overview of different kinds of interaction which shows the diversity and the richness of this function, our approach consists of considering the interaction as a genuine information processing system which communicates and cooperates with the human and the virtual world.
Les "Spirales de contextes" dans I'interaction homme-machine BIBAFull-Text 15
  Henry Lieberman
Context-sensitive and context-aware interfaces have become increasingly important in human-computer interaction, as we seek to make interfaces more adaptable and personalized. Context can include, for example, time, place, history of interaction, user preferences, and any relevant information external to the application.
   But fundamental problem remains, just how much context should you use? If you use too little, the application remains inflexible; if you use too much you risk slowing down the application, hurting interactivity.
   I propose the idea of Spiral Contexts, a dynamic approach that consists of starting out with small, restricted context, and gradually expanding it (in time and space), interleaved with user interaction.
Analyse de performance et modéles de Tâches comme support à la conception rationnelle des systèmes interactifs BIBAFull-Text 17-24
  Xavier Lacaze; Philippe Palanque; David Navarre
The aim of this paper is to propose extensions to QOC design rationale notation. In this paper two extensions are proposed. First extension deals with the addition of quantitative information into QOC diagrams coming from the exploitation of temporal information in the system model and the use of performance evaluation techniques. Second extension deals with the addition of information related to human factors analysis of work activities and represented in task models and scenarios. These extensions are exemplified on a simple case study comparing the efficiency of two different currency convertors.
Analyses de I'activité et IHM pour I'éducation BIBAFull-Text 25-32
  Elisabeth Delozanne; Brigitte Grugeon; Pierre Jacoboni
In this paper we explore the role of users' activity analysis when designing and evaluating interactive systems for school education. What kinds of activity analysis are available? How do they support design and evaluation? We do not pretend to answer all these questions but we review the answers we gave in our own research in Interactive Learning Environments around the Lingot project. This project aims to design new instrument to support teachers when they regulate learning in their classroom. This paper is based on studies of teacher working with a prototype.
Architectures multi-agents génériques à base de réseaux de Pétri colorés temporisés pour la fusion multimodale en entrée BIBAFull-Text 33-40
  Hicham Djenidi; Amar Ramdane-Cherif; Chakib Tadj; Nicole Levy
The multimodal featuring fusion for natural human-computer interaction involves complex intelligent architectures to face unexpected errors and mistakes made by users. These architectures should react to events that occur simultaneously with eventual redundancy from different input media. In this paper, agent based generic architectures for multimedia multimodal dialog protocols are proposed. Global agents are decomposed into relevant components. Each element is modeled separately. The elementary models are then linked together into timed colored Petri nets to obtain the full architecture. Hence, maintainability, understandability and modification of the architecture are facilitated. For validation purpose, the proposed multi-agent architectures are applied on a practical example.
Collaboration homme-machine: vers un partage dynamique BIBAFull-Text 41-48
  Ahmad Skaf; Bertrand David
The man-machine cooperative systems design constitutes a significant concern in a great number of fields and in particular in industrial engineering, where the control-command systems are numerous. In this article we propose an original approach, which leads towards a dynamic allocation of actions between man and machine. After the problem presentation and comparison with existing work, we describe our proposal based on an original modelling and an algorithm of distribution which can be used in various contexts. This one allows in particular a dynamic allocation of actions to the man and the machine in relation with expressed aims. The purpose of design of such systems is to find a global performance in relation with the human actor capabilities and those of the machine.
Construction et évolution des représentations mentales lors des premières utilisations d' un service de dialogue en langage naturel BIBAFull-Text 49-56
  Virginie Amiel; Patrice Terrier; Gérard Poulain; Jean-Marie Cellier
This research is based on the study of the cognitive processes implemented during the first use of a new information search service in natural language. Our goal is to bring together elements on the development and the evolution of user's mental representation.
   The mental representations shown by users were isolated following on one hand the analysis of verbal productions, collected during four interaction tasks with a dialog service, and on the other hand a questionnaire about goals and subgoals, possible actions and system capacities.
   This study is aligned with the work of a research laboratory from France Telecom R&D. The service used is a provider prototype using a simple telephone interaction with flexible language.
   Our results show that the initial representation build by the user depends on his computer knowledge. Thereafter, the user representation evolved during the successive interactions thanks to the increasing of his declarative knowledge and his procedural abilities. The adjustment of the representation is done for every user, however it is more or less efficient according to the relevance of the analogy chosen.
Demandes d'aide procédurale: spécification des besoins d'utilisateurs novices BIBAFull-Text 57-64
  Antonio Capobianco
This paper presents a study of online help dialogues This paper presents a study of online help dialogues between novice users and human experts. This study is focused on the modelisation of the novice users actual information needs, taking into account the dynamic aspects of the activity. Our analysis revealed information needs that overstep the usual semantic definition of help information categories.
   Dialogue analysis results indicate that novice users request different types of information from the experts namely semantic, syntactic and pragmatic. These results suggest that the novices' requests for procedural information depend on the ongoing step of the activity cycle to fulfill the user's actual goal. This cycle includes the completion of the following steps: planning of an action, execution of the planned procedure/task, and assessment of the effects resulting from the carried out actions on the system's current state.
   The analysis of 10 help dialogues led us to define procedural help activity, in this specific interaction context, as a complex process involving the combination of several types of information. Using this specific pattern of help information should ensure most effective online help support.
« e-Ti », prototype d'assistance à la planification d'itinéraires multimodaux: spécifications ergonomiques pour une application web sur la base d'une démarche expérimentale BIBAFull-Text 65-72
  Emmanuel Duplàa; Willemien Visser
This paper presents an experimental study and a prototype support tool on the Web for planning multimodal routes. The ergonomic specifications underlying the support tool were formulated on the basis of data collected in the study, conducted with future users of the tool. People with different knowledge levels on the relevant transportation means and with different abilities in route planning, had to design routes using two different assistance systems. The first one only presents information, leaving design up to the user; the second system designs the route on the basis of constraints specified by the user. Results show that preference for a system is correlated with the user's knowledge level and competence in route planning. The prototype is being validated via its intended users.
Intégration d'un modèle de tâche dans une démarche sûre de construction d'interface BIBAFull-Text 73-80
  Mickaël Baron
The approach presented in this contribution is the collaboration of interface builders and model based systems in order to define a method and an environment for building safe interactive applications. We concentrate particularly on the integration of a task model, and we describe the interactive tools that allow editing and evaluating this model.
Interfaces procédurales BIBAFull-Text 81-88
  Guy A. Boy
A procedural interface enables users to concentrate on the task they are performing and to avoid any inappropriate overload coming from the use of desktop interfaces (where procedures are implicitly office-oriented). It automatically reconfigure itself depending its context of use, taking into account three types of cognitive functions: anticipation, interaction and recovery. A procedural interface involves several concepts such as simplicity, redundancy, cognitive stability and cognitive support. An example is provided in the domain of computer-supported meetings.
Jeu et Réalité Mixte: retours d'expérience BIBAFull-Text 89-96
  Alexandre Demeure; Gaëlle Calvary
This paper deals with Games and Mixed Reality. Based on players experience, it proposes both a model and a classification of mixed games. The model helps the designer in specifying entities that are involved in the game. The specification covers both the support of the entities and their internal and external relationships. The classification structures games in levels of abstraction. It gives rise to a rough evaluation method applied to a real case study: Rasende Roboter. This game has been suggested by players because of its attractiveness. The paper compares the traditional and mixed versions.
La personnalisation de I'interaction dans des contextes multimodaux et multicanaux: une première approche pour le commerce electronique BIBAFull-Text 97-104
  Alain Derycke; José Rouillard
This article presents a reflexion on new forms of interaction not yet approached by the HCI community. It's the study of the convergences and divergences between the personalization seen under two complementary angles: direct marketing on the one hand, and person/system interfaces on the other hand. The multimodality has been studied since many years, and personalization has been used in marketing for a long time, but seldom, both were studied jointly. A prototype of multimodal user adapted E-commerce site is presented. That opens, according to us, many tracks of research on the personnalization/multimodality intersection.
Le contexteur: une abstraction logicielle pour la réalisation de systèmes interactifs sensibles au contexte BIBAFull-Text 105-112
  Gaëtan Rey; Joëlle Coutaz
Important information about interaction context is developed during the design process. In this article, we propose a formalism to encode and preserve this information during system implementation. We begin by proposing a definition of interaction context. We then present the "Contextor", a software concept that provides developers with a tool for modeling context. We show how contextors can be composed into layers of abstraction and how contextors fit within the Arch software architecture model. We present an implementation architecture based on the Peer to Peer computing.
Le modèle d'architecture Clover pour les collecticiels BIBAFull-Text 113-120
  Yann Laurillau; Laurence Nigay
In this paper we present the Clover architectural model, a new conceptual architectural model for groupware. Our model results from the combination of the layer approach of Dewan's generic architecture with the functional decomposition of the Clover design model. The Clover design model defines three classes of services that a groupware may support, namely, production, communication and coordination services. The three classes of services can be found in each functional layer of our model. Our model is illustrated with the CoVitesse system, its software being organized according to our Clover architectural model.
Les tests utilisateurs: avantages et inconvénients des passations individuelles et par paires BIBAFull-Text 121-128
  Noëlly Grondin; J. M. Christian Bastien; Blandine Agopian
This article presents the advantages and drawbacks of individual and paired-user testing in terms of number and type of usability problems uncovered. Thirty-two participants had to perform 8 tasks designed to allow the evaluation of interactive tv services. For half of the participants (16) the test session was conducted individually: for the other half, the test session employed pairs of users (8x2 participants) performing the tasks together. The main results indicate that task completion times do not differ statistically between groups and that paired-user testing involve better success rates. Individual sessions allow the identification of more usability problems while paired-user sessions involve a better understanding of the difficulties users encountered. As for the type of usability problems uncovered (Guidance, Compatibility, etc.), differences between the two groups were observed. The results are discussed in relation to the commentairies published on the paired-user testing.
Programmer I'interaction avec des machines à états hiérarchiques BIBAFull-Text 129-136
  Renaud Blanch
Writing interactive software leads, due to the lack of adapted control structures, to a code that is difficult to maintain and reuse. Formalisms adapted to the description and to the specification of interactions do exist. This paper proposes to extend imperative programming languages with a control structure borrowed from one of those formalisms: the hierarchical state machines.
Rapports entre conception institutionnelle et conception dans I'usage BIBAFull-Text 137-144
  Gaëtan Bourmaud; Xavier Rétaux
For some authors, design does not stop at the artifact sale or deployment [11,16,18,20]. By qualifying appropriating processes of artifacts by users as design in use processes, these authors have opened new perspectives for design [2-5,7,8,11,16-20]. We will present and develop one of these approaches -- instrumental approach [16,19] -- in the course of two different design situations. We will particularly present design in use processes. We will interest in the relationship between this design and institutional design. To do this, we will base on interviews and analyses of players' and operators' activity and the description of part of the two design processes observed. Finally, we will draw conclusions on the differences and similarities that appear between these two situations.
Synthétiser I'intention d'un pilote pour Définir de nou-veaux équipements de bord BIBAFull-Text 145-152
  Bruno d'Ausbourg
Mode confusion is a serious problem in aviation safety. New avionics systems are complex and make it difficult for pilots to maintain awareness of the actual states or modes of the flight deck automation. This paper investigates whether it is possible to synthesize the intention of a pilot from the way she interacts with the equipments of the flight deck. It explores then how it would be possible to use such intention data for verifying and validating the behaviors of these equipments and to design new behaviors that take into account this intention in order to improve interactions with the pilot.
Une démarche structurée pour la conception et l'évaluation d'applications Web par l'exploitation synergique des modèles de tâche et de navigation BIBAFull-Text 153-160
  Marco Winckler; Christelle Farenc; Philippe Palanque
Even though the importance of Web applications is still increasing, design practice in this area is still mainly based on informal techniques and methods. In practice, few description techniques are available to support web modeling and it is unusual to model web applications even though modeling is usually the corner stone of "classical" computer applications. Models not only formalize requirements but also they can help to assess the design in all the stages of the development process. In this paper we present notations dedicated to web navigation modeling and how they can affect the design process. In addition we discuss how task models could be used to assess navigation models according to user's activity. Our aim with this kind of evaluation is to ensure (prior to implementation) that important users tasks can (or cannot) be performed with the system.
Visualisations compactes: une approche déclarative pour la visualisation d'information BIBAFull-Text 161-168
  Thomas Baudel
We introduce a descriptive model that allows the definition of a large class of information visualization algorithms with a small number of parameters. Compact visualizations, which we conjecture is equivalent to the class of visualizations that can be rendered in a time directly proportional to the size of the input data, are defined by a fixed dataflow architecture: clustering and subclustering of input data, sort, graphic primitives and graphic attributes generation. At each step, the parameters are expressions of the host programming language, which include input attribute names and local variable names. Local variables are a specific concept that allows us to extend the expressiveness of the dataflow architecture. We introduce our model formally, and then show its expressiveness with a few examples.
Apports perceptivo-cognitifs des avatars dans des environnements virtuels familier, semi-familier et non familier BIBAFull-Text 169-176
  Sandrine Tonnoir; Catherine Berenblit
The fundamental studies of perceptivo-cognitive type on the contributions of the avatars in the virtual scenes are generally carried out in situations of laboratory. For our own projects, we needed to evaluate these contributions in complex industrial scenes. This document is the synthesis of this applicative study.
   The study presented treats of the appreciation of the avatars carrying qualitative information; they do not carry the principal information but populate virtual environments. This study aims to better know information than these avatars convey by their presence in order to reinforce the messages contained in the application and to avoid the misinterpretations or ambiguity they could bring if this factor is not controlled.
   The principal results of the experimentation are the following:
  • In any type of virtual environment, the avatars bring realism and "life". In
       an unfamiliar environment, they also allow to provide indications on the
       work and the activity in environment, in particular with their working
       clothes and actions.
  • Nevertheless, to be appreciated and effective, these avatars will be
       sufficiently realistic and their behaviors must be relevant compared to
       environment. Mobility alone is not enough, their actions must be
       coordinated, fluid and be centered on an identifiable objective of task. The
       clothes of the civil avatars must also be considered because it conveys a
       significant psychosociological dimension.
  • Modèles de présentation d'informations audio 3D pour les usagers mobiles BIBAFull-Text 177-182
      Safia Djennane
    With the emergence of the mobile Internet combined with wearable personal computing, we are now entering a new information era where PCs are self-adapting their resources to human bodies, minds and preferences, prevailing a more effective work environment. In this new world, working effectively is inextricably related to accessing reliable information sources anytime and anywhere. In this paper, we propose innovative UI news presentations based on three-dimensional (3-D) audio modeling.
       We illustrate how news, weather and business reports are extracted, spatialized and presented to mobile users wearing permissive earsets.
    Objets graphiques transactionnels: une méthode ouverte pour la création d'applications interactives distribuées synchrones BIBAFull-Text 183-190
      Yunpeng Zhao; Thomas Baudel; Jie Zhou
    We introduce Transactional Graphic Objects, an open approach to share graphic objects in direct-manipulation distant CSCW (Computer Supported Cooperative Work) applications. We also present the client-server architecture for such applications. The graphic objects hosted by the server are accessed by clients by means of transactions in an XML based language, the Graphic Object Access Language (GOAL). GOAL is defined as an open communication protocol between the client and the server. Conforming to the common protocol, the server and the client can be implemented using different languages or techniques. GOAL is language independent; it can be carried over HTTP and pass transparently through enterprise firewalls. This makes the construction of efficient heterogeneous direct manipulation CSCW applications much easier. GOAL is also compatible with the SOAP protocol and can be used to implement interactive Web Services. The transactional approach makes the handling of concurrent access and session management transparent to the application developer.
    Les principes de dialogue: une étape incontournable dans la conception de l'interaction H/M BIBAFull-Text 191-198
      Y. Haradji; J. B. Haué; P. Suignard
    This paper is based upon the practice of the Human-Machine Interaction Group at EDF Research and Development. It describes essentially the said stage "dialogue principles" for user interfaces design.
    Astrolabe ou la nagigation tout en images et en sons BIBAFull-Text 199-200
      N. Portolan; S. Jumpertz; O. Koechlin
    Astrolabe is a demonstrator of a man-machine interface capable of displaying what a picture-based search tool could be like in a personal or professional picture collection. Astrolabe is a textless interface through which users may search for pictures on the basis of colours, shapes and/or associated sounds... a tool for research, an invitation to wandering about, to discovery... so was the interface perceived by users. The trail is still to be followed up.
    InfoCrible: edition interactive de visualisations compactes BIBAFull-Text 201-202
      Thomas Baudel
    We introduce an information visualization editor, which allows both the exploration of a data set and the exploration of possible visualizations of this data set. This environment relies on the definition of Compact Visualizations, which are a very large class of visualizations that depend from a relatively small number of parameters. This environment can either be targeted as a visual exploration tool for advanced users, or as a development environment to define and export quickly specifically targeted customizable visualizations, to be manipulated by end users.
    Interface-esquisse effacée en ingénierie de conception BIBAFull-Text 203-204
      Pierre Leclercq
    In order to respond to the difficulty to really assist the designer in conceptual design, we suggest to carry out a tool able to interpret design sketches early in the design process. For that purpose, we use the concept of the "not present interface", the only one compatible with the cognitive process involved in sketching. We present here the principles of such an interface, illustrated by EsQUIsE, a software prototype for capturing and interpreting architectural sketches.
    Programmation visuelle et editeurs musicaux pour la composition assistée par ordinateur BIBAFull-Text 205-206
      Carlos Agon; Gérard Assayag
    This article presents the architecture of OpenMusic, an environment for computer assisted musical composition. The main idea is to provide to the composer a merely graphical environment, where he or she stands both as a programmer and as an user/musician. OpenMusic deals with these two aspects via two concepts: visual programs and musical notation editors.
    Adaptation des IHM: taxonomies et archi. logicielle BIBAFull-Text 207-210
      David Thevenin; Joëlle Coutaz
    Most of taxonomies about IHM adaptation are made for reasoning on adaptation to the user. They do not cover the adaptation to several targets (platform, environment). Recently, some talk about adaptation to multi-target but without clarifying the nature of software components influenced by the adaptation process. Here, we present a complementary axis based on the functional decomposition of Arch model, which ll this gap.
    Architecture logicielle conceptuelle pour la capture de contexte BIBAFull-Text 211-214
      Laurence Nigay; Phil Gray
    This paper describes a PAC-Amodeus software architectural solution for context-aware systems. The software architectural solution is based on an architecture dedicated to multimodal interaction. Indeed we argue in this paper that several software design issues are common between multimodal systems and context-aware systems. Our architectural solution is intentionally generic, intended to serve as the basis for a wide range of possible systems and compatible with the existing architectural approaches.
    Etude comparative de méthodes d'identification de la perception des usagers sur la qualité des sites Web BIBAFull-Text 215-218
      Ghuilaine Clouet; Isabelle Lambert
    A comparative study of two methods, individual interviews and focus groups, with users on their quality perception of e-commerce sites has revealed the comparative performances of the two methods concerning the evaluation dimensions' elaboration.
    Evaluation de la performance d'un opérateur en fonction de sa tâche. application aux IHM BIBAFull-Text 219-222
      Laurent Bayssié; Laurent Chaudron
    In this paper we propose a methodology -- dP/dT -- for the evaluation of evolving interaction systems in the general frame of aeronautics.
    Ivy: un bus logiciel au service du développement de prototypes de systèmes interactifs BIBAFull-Text 223-226
      Marcellin Buisson; Alexandre Bustico; Stéphane Chatty; Francois-Régis Colin; Yannick Jestin; Sébastien Maury; Christophe Mertz; Philippe Truillet
    This paper focuses on the experience we have acquired by developing and using the Ivy software bus to design human-computer interactive prototypes for Air Traffic Control. We list its properties for designing and developing light and powerful HMIs. By presenting our experience, we hope it will foster the design and development of the future architectures of interactive systems for research needs.
    Le puits: un dispositif de communication audio-vidéo pour la téléconvivialité BIBAFull-Text 227-230
      Nicolas Roussel
    This paper presents the "well", a group communication device designed to support informal meetings. The well complements the traditional videoconferencing systems that support more formal meetings.
       It combines audio and video transmissions with an original design to support teleconviviality, the emergence of a relaxed and joyful atmosphere well adapted to distributed informal communication.
    LYPO: « vers une perception applicative du WEB » BIBAFull-Text 231-234
      Denis Payet
    This paper presents a new way of designing navigation on the WEB. It describes the LYPO principle which consists in associating to an Internet site an applicative environment presented to the user as a kind of "virtual office" similar to the familiar user desktop metaphor, rather than a simple set of HTML documents. The applicative environment offers more freedom of action to the site visitor, and allows the webmaster to design a richer site in terms of functionnality and interaction.
    Moteurs de recherche: vers une prise en compte de l'accessibilité pour les déficients visuels et les seniors BIBAFull-Text 235-238
      Raoul Masson; Gabriel Michel
    For visually impaired and seniors, information search on the Web involves often many problems. Indeed, although they are relevant, the sites returned by search engines are rarely accessible and if some exist, they can be found very far in the list of sites. Do deal with this problem, we are developing a software agent meant to filter and re-classify engine results based on several predefined user profiles for which characteristics as regards accessibility are well known.
    Outil de prototypage pour la conception et l'evaluation d'interfaces utilisateur multimodales BIBAFull-Text 239-242
      Marie-Luce Bourguet
    Designing and implementing applications that can handle multiple recognition-based interaction technologies such as speech and gesture inputs is a difficult task. IMBuilder and MEngine are the two components of a new toolkit for rapidly creating and testing multimodal interface designs. First, an interaction model is specified in the form of a collection of finite state machines, using a simple graphical tool (IMBuilder). Then, this interaction model can be tested in a multimodal framework (MEngine) that automatically performs input recognition (speech and gesture) and modality integration. Developers can build complete multimodal applications without concerning themselves with the recognition engine internals and modality integration. Furthermore, several interaction models can be rapidly tested in order to achieve the best use and combination of input modalities with minimal implementation effort.
    Outils de modélisation des tâches utilisateurs: exigences du point de vue utilisation BIBAFull-Text 243-246
      Vincent Lucquiaud; Dominique Scapin; Francis Jambon
    User task analysis is a critical step in the a design process of interactive systems. The large set of user task models available today may lead to assume that this step is well supported. However, these models are little or not tool-supported. This paper focuses on user requirements the user task analysis tools. These requirements are organized into three categories: description support, model data use and model data utilities. Each category is illustrated by examples coming from available tools: IMAD, Euterpe, CTTE and Tamot.
    Planification d'itinéraires urbains: pistes pour un système d'assistance BIBAFull-Text 247-250
      Sébastien Chalmé; Willemien Visser; Michel Denis
    Onboard navigational aid systems are a central topic in the road-transportation domain. The currently available systems are designed so that they usually deliver the "objectively" "optimal" routes. Drivers, however, often prefer other routes due to individual cognitive or motivational reasons. Our research program aims at identifying the cognitive processes involved in route planning, and providing ergonomic specifications for onboard systems dedicated to support drivers' route planning. We conducted two experiments in which participants were asked to plan an itinerary through a city, in which they were expected to complete tasks with spatial or / and temporal constraints. We examined if participants' cognitive activities were affected by specific environment knowledge, by tasks being constrained temporally and by time available for planning. On the basis of these results and of an ergonomic analysis of aid systems, we formulate some directions for the development of a system that might support drivers in their planning activities.
    Processus de génération d'IHM multicibles pour applications interactives BIBAFull-Text 251-254
      Kinan Samaan; Olivier Delotte; Franck Tarpin-Bernard
    This article deals with the generation of multitargets HCI for interactive applications. We define basis for the generation process of such applications by identifying the key phases of this approach. This method covers several phases from task modeling to the definition of the concrete interfaces for various supports (PC, PDA, WAP, TVI...). In a second time, we propose an automatic mechanism to select the physical interactors of the interface based on the physical characteristics of the target devices (means of interaction, size, color, ...). Our final goal is to automate at the most the process of generation of multi-targets HCI.
    Processus et paramètres de conception de la sonification BIBAFull-Text 255-258
      Sylvain Daudé; Laurence Nigay
    In this paper we present a unified framework for the design of audible interfaces. We describe the steps of the sonification process and their parameters. The process is modeled as a sequence of transformation functions from the data to present to the produced sounds.
       The usefulness of the framework for classifying existing audible interfaces and for designing new ones is then discussed.
    Un environnement multimedia pour augmenter la convivialite des examens d'irm BIBAFull-Text 259-262
      Jean-Yves Ramel; Patrick Prévot
    This paper explains the design of a multimedia environment that enables children to face more easily MRI examinations. The idea is to transform the initial hospital environment to make it more convivial for children. Our aim is to add a play interface between the hospital and the children world. After the description of the initial environment of the pediatric hospital service, this paper shows how the use of multimedia devices eases the acceptance of a aggressive real world. By adding virtuality, the MRI scanner and center have been turning away from their diagnostic and stressful functions to become a convivial place for children.
    Une interface 3D multi-échelle pour la visualisation et la navigation dans de grands documents XML BIBAFull-Text 263-266
      Christian Jacquemin; Michèle Jardino
    The visualization of large documents such as technical reports or professional manuals is an important issue. For this purpose, we have developed 3D-XV, an interface for visualizing large structured documents through a hierarchical 3D-model. In addition to textual and structural information, the model associates thematic content with colors. In the query mode, passage relevance is described through local histograms. The core textual content can be accessed through textured block faces or through a Web browser. Future work on paragraph signalling and variations of the geometrical model are proposed. 3D-XV is compared to previous approaches to passage retrieval and visualization of thematic links.
    Vers des modeleurs 3D créatifs: étude de dessins d'architectes BIBAFull-Text 267-270
      Stéphane Huot; Cédric Dumas
    This paper describes an experiment we conduct to provide designers with an advanced 3D modelling Human-Computer Interaction. The main project -- called GINA [4], a French acronym for Interactive and Natural Geometry-expect to introduce new intuitive and creative 3D modeling tools, relying on 2D perspective drawing reconstruction. This domain study will help us to deduce implications for Human-Computer Interaction in such a system.
    VideoWorkspace: une boîte à outils pour l'exploration de nouvelles techniques de gestion de fenêtres BIBAFull-Text 271-274
      Nicolas Roussel
    In this paper, we present video Workspace, a toolkit designed to facilitate the exploration of new workspace interaction techniques using both a low-fidelity and a high-fidelity approach.
    Visages parlants: quels visages pour quelles voix? BIBAFull-Text 275-278
      Marc Mersiol; Noël Chateau
    The integration of synthetic faces and voices (what we call "talking heads") allows to imagine new man-machine interfaces. But before making an extensive use of talking heads, several issues have to be checked according to their acceptability. An important issue is to make sure that the used synthetic voices match to their faces. The scope of this paper is to study the coherence that might exist between synthetic voices and faces. Twenty-four subjects rated the coherence of all combinations between five faces and three voices for female and male talking heads. The main results of this study show that every associations between faces and voices are not relevant and that some associations are better rated than others according to qualitative criteria.

    This paper describes the use of adjacency matrices for the visualization of co-activity graphs such as social networks. We describe their use for analysing and understanding constraint-oriented programs. We show that the use of adjacency matrices for the visualization of the variables vs. constraints graph makes it possible to visualize how the problem was modeled and to compare the activity in various regions of the graph while the problem is being solved.

    Sometimes, an operator using a complex system is overloaded by too much information. He has to solve the problem alone and quickly, deciding what to do on pieces of information that are displayed. An adaptive composition system can collaborate with him to lighten his task. Our work concerns relevance as a property for guiding information composition adaptation.

    This study is on the natural MMI concept. The purpose of this work is twice. First, to define criterions and a method to assess the MMI. This method, based on verbal reports, have to measure the natural level of MMI. Second, to design a demonstration-software to assess the natural level of MMI. The demonstration-software automatically processes the verbal reports of users.
