Claviers GAG: claviers logiciels optimisés pour la saisie de texte au stylet BIBAFull-Text 3-10
  Mathieu Raynal
The character layout on the keyboards of our computers dates from more than one century and had been designed for reasons which are no longer standing. This layout is all the more annoying when the text input is doing with one finger (or via a stylus) such as for example on soft-keyboards.
   This article proposes a system (based on a genetic algorithm) making it possible to generate key layouts with a character arrangement which theoretically enable to increase the text input speed. The generation of soft keyboard with our system was tested for English and French. The keyboards we propose, engendered from our system, would theoretically increase the text input speed with a stylus of almost 50% compared with the qwerty and azerty soft keyboards.
Co-conception d'expériences interactives augmentées dédiées aux situations muséales BIBAFull-Text 11-18
  Cédric Bach; Pascal Salembier; Emmanuel Dubois
This paper shows the different steps of a co-design process dedicated to build augmented interactive experiments in Museums. This process enables an analytic framework listing the different dimensions to tackle during the design of augmented interactions. These different steps are illustrated by a case of study in the classification of life.
DoPIdom: une approche de l'interaction et de la collaboration centrée sur les documents BIBAFull-Text 19-26
  Olivier Beaudoux
Documents are ubiquitous in modern desktop environments, yet these environments are based on the notion of application rather than document. However, document-centric systems such as OpenDoc and Web browsers illustrate the power of using an integrated environment to interact with documents of various types. This paper presents the DoPIdom model and toolkit dedicated for the development of interactive and collaborative environments centered on XML documents. DoPIdom provides XML active transformations for transforming abstract documents into presentations, interactive components for defining the behaviors of documents and instruments, and event points for sharing documents and/or presentations. The paper presents the overall DoPIdom approach and explains the design and development of interactive and collaborative components for our Sovigo SVG drawing environment.
État de l'art des techniques de présentation d'information sur écran d'assistant numérique personnel BIBAFull-Text 27-34
  Sami Baffoun; Jean-Marc Robert
The design of user interfaces on PDAs is increasingly challenging for developers as the need to view large quantities of information increases. The small size of the screen makes it difficult to have an overall picture of the content of the interface as well as of a complete view of all pieces of information that the mobile user needs to accomplish his/her task. This paper presents a state of the art of the different techniques of presentation on PDA screens that have been developed in response to the lack of space on these screens. By so doing, we also present a typology of techniques of information presentation on PDAs and several evaluation results.
Évaluation des dispositifs mobiles: sur le terrain ou en laboratoire? BIBAFull-Text 35-42
  Francis Jambon; Caroline Golanski; Pierre-Jacques Pommier
This article focuses on usability testing of mobile devices "in the wild". We are interested in ensuring the methodological validity of these analyses. We so implemented an original approach which consists in carrying out a meta-evaluation of two evaluations of the same quasi-realistic experiment. The first one uses a traditional methodology similar to usability laboratory settings. The second one mimics the conditions of experiments carried out "in the wild". Our objective is to validate -in advance-the methodology for usability evaluations "in the wild".
Flexibilité et modularité pour la conception d'interactions: le modèle d'architecture logicielle des graphes combinés BIBAFull-Text 43-50
  Stéphane Huot; Pierre Dragicevic; Cédric Dumas
This paper presents the Mixed Graphs software architecture of the MAGGLITE post-WIMP toolkit. This model extends and refines the scene graph architecture by describing interactions with another structure: interaction graphs. Graphs are dynamically combined at runtime, thanks to specific communication components named Interaction Access Points. This adaptable and modular approach for describing interactive graphics is gainful for prototyping, implementing and using alternative input devices and/or interaction techniques.
La soumission et la domination culturelle dans les interfaces: analyse lexicale comparative de 100 sites web personnel français et québécois Éric Brangie, Pascal Tisserant BIBAFull-Text 51-58
The analysis of 100 French and Quebecker personal web sites has made it possible to evaluate how men, women, French people and Quebec inhabitants introduce themselves through the Web. Our results underline three important factors in the elaboration of their personal pages: gender and national identities, plus the balance of powers between the different social groups. The lexical analysis shows that these personal pages are characterized by two semantic fields: On the one hand, a theme class referring to a professional vocabulary and which is mainly generated by male and French users. On the other hand, a class expressing more sentimental values and which is much related to both the female and Quebec identities.
Les transitions visuelles différenciées: principes et applications BIBAFull-Text 59-66
  Céline Schlienger; Pierre Dragicevic; Claire Ollagnon; Stéphane Chatty
In order to support animation design in graphics interfaces, we introduce the concept of visual transition. We then use this descriptive model to introduce a new animation technique: differentiated visual transitions, which allow conveying information by varying visual transitions. This technique is illustrated on concrete cases with a professional animator. We also introduce some properties of differential visual transitions and address design questions.
MatrixExplorer: un système pour l'analyse exploratoire de réseaux sociaux BIBAFull-Text 67-74
  Nathalie Henry; Jean-Daniel Fekete
In this article, we present the MatrixExplorer system, aimed at exploring social networks. It has been designed for researchers in social sciences -- sociology and history -- and is based on an interactive process with multiple views. MatrixExplorer design comes from several interviews with researchers and a participatory design session that helped us assess users need in term of visualization and exploration of social networks. MatrixExplorer provides two representations for graphs: matrices and node-link diagrams. Exploration starts from a matrix representation to preserve readability and provides an iterative process to filter and organize the graph to reveal a structure and abstract it so that it can eventually be visualized as a readable node-link diagram.
Mixage mobile BIBAFull-Text 75-82
  Olivier Delerue; Olivier Warusfel
This paper takes two examples of Audio Augmented Realities and Wave Field Synthesis to show evidence of some evolution in the task of a sound engineer: his task which is commonly known to be static becomes necessarily mobile in these particular contexts.
   We first comment and describe these new tasks and show evidence of the needs for evolution of the corresponding tools: we show why these mixing situations can not be properly handled without an appropriate design tool that allows controlling the virtual scene while walking through the rendering space.
   We then present our proposition for such a context through two software prototypes: first, the "Listen-Space" application, an authoring tool specially designed for the particular case of audio augmented realities and that allows performing mobile control of spatialization when run on a wireless ultra-portable tablet PC. Second, we describe the "L-Scanner", a "see-through" interface implementation dedicated to the control of sound spatialization.
   We finally discuss applications of our system such as collaborative mixing, thanks to a distributed software architecture as well as the split between the graphic user control interface and the DSP audio rendering engine: in this context, each participant can work on a shared virtual sound scene while adapting its representation at its personal taste and needs.
Ordre des informations et effet de modalité pour une recherche de restaurants BIBAFull-Text 83-89
  Ludovic Le Bigot; Éric Jamet; Jean-François Rouet; Gérard Poulain
This study investigates the influence of interaction mode on the information order in a human-computer natural dialogue. Spoken and written interactions were compared using a real natural language information retrieval system. In two experiments, participants performed several task-oriented dialogue scenarios either with a phone or a Web interface. The goal was to locate restaurants with specific characteristics among these present in a database. A typical information order emerged for restaurant search (food type, location, and price) whatever the dialogue mode. However, the amount of information was higher in the written than in the spoken mode. The structure of utterances in service dialogue appears to follow canonical ordering. This order can be used for optimize the system feedback.
Scénarios transactionnels sur internet: l'application de la méthode du coût généralisé BIBAFull-Text 91-98
  Claudine Bonneau; Pierre-Léonard Harvey
Even though usability research done in the past 10 years have contributed to the design of more easy-to-use websites, few methods exist for the analysis of resources deployed by user performing a task on Internet. In this paper we explain how Abraham Moles' generalized cost method can be adapted to Internet usages field in order to take into consideration the disappointment, uncertainty and mental efforts taking place during the online experience. Our aim is to guide the developers by providing a more comprehensive description of the action.
SMCanvas: augmenter la boîte à outils Java Swing pour prototyper des techniques d'interaction avancées BIBAFull-Text 99-106
  Caroline Appert; Michel Beaudouin-Lafon
This article presents SMCanvas, an extension of the Java Swing toolkit dedicated to prototyping and teaching graphical interaction. SMCanvas uses a simplified scene graph for rendering and state machines for interaction. The use of polymorphism and reification helps combine ease of use and power of expression. We describe our experience of using SMCanvas with Master level students for programming advanced interactions, and propose to evaluate user interface tools with benchmarks.
Support mobile à la tâche: médiation utilisateur - monde réel par l'intermédiaire d'un ordinateur porté BIBAFull-Text 107-114
  Nicolas Plouznikoff; Alexandre Plouznikoff; Michel Desmarais; Jean-Marc Robert
After reminding the characteristics and the fundamental role of wearable computing and wearable computers for mobile task support, this paper presents the state of our research on three human-real world mediation levels: virtual alteration, virtualization and diffusion. To enhance a user's performances, the first mediation level investigates the virtual modification of existing interfaces while the second undertakes their abstraction in order to recreate them in a form of augmented reality. The last mediation level draws upon the task's artifacts and disseminates the interfaces' functionalities directly into the environment. We present for each of these mediation levels an analysis of their characteristics, an evaluation of their advantages for task support and our most recent experiments. Finally, we highlight the similarities and differences between these mediation levels to guide designers in their selection.
Trust in new decision aid systems BIBAFull-Text 115-122
  Hasmik Atoyan; Jean-Rémi Duquet; Jean-Marc Robert
One of the main challenges to face concerning the safe utilization of new technologies in complex systems concerns the level of trust the operators have in the system. Danger exists when the operators have a low level of trust in it, as well as it also exists when they overtrust the system. This paper presents an extensive review of theoretical, empirical, and experimental studies on trust in systems. Its goal is to help system designers by proposing a set of design rules and guidelines on how to support appropriate trust tuning in new decision aid systems.
Validation et vérification formelles de systèmes interactifs multi-modaux fondées sur la preuve BIBAFull-Text 123-130
  Yamine Ait-Ameur; Idir Ait-Sadoune; Jean-Marc Mota; Mickael Baron
This paper focuses on the formal validation and verification of multi-modal human computer interfaces. It describes part of the obtained results of the French RNRT VERBATIM project. It focuses on the application of a formal proof based technique, namely the event B method. We outline the capability of this technique to support the design of multi-modal human computer interfaces, in particular, the capability to support the expression and the verification of properties issued from the CARE family. The proposed approach uses notations and semi-formal techniques issued from the HCI design area.
Vers la maîtrise du virtuel à travers le réel: un nouvel usage de l'informatique en design BIBAFull-Text 131-138
  Tomás Dorta
This paper proposes a new paradigm in computer-aided design. Considering, on one hand the traditional sketches and mock-ups, and digital techniques on the other, this approach fuses the two and proposes new techniques that use the performance of the digital with the capacities of the manual, without replacing or imitating one or the other. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems that do not consider how designers actually work. This new approach is presented through two new innovative techniques.
Analyse des logiciels d'application spécialisée pour le courtage en épargne collective BIBAFull-Text 141-144
  Alexandre Moïse
Based on an abstraction hierarchy for mutual fund units portfolio management, an analysis of specialized application softwares for group saving plans has been performed. The results indicate that the state of the art regarding human-computer interfaces for these softwares is characterized by (1) an essentially alphanumeric presentation and interaction mode, (2) the dispersion of information through various specialized application softwares, and (3) the absence of certain information from higher level of abstraction. These results suggest to push research toward ecological interface design for this application domain.
Analyse descriptive de trajectories perceptives BIBAFull-Text 145-148
  Yusr Amamou; John Stewart
We wished in this present study, to describe and automate the identification of the strategies implemented by blindfolded subjects. we had resource to the transformation of Fourier in our description. The transform of Fourier is known by his historical relevance in the characterization of the rhythmic behaviour. The trajectories of the subjects are recorded by means of substitution tactile interface. We could define descriptors that differentiate the perceptive strategies. deployed by the subjects. This study has goal to facilitate the acquisition of sensory substitution device. by offering to the subjects rules and strategies which they can adopt. thus they reduce the period of training phase.
Developpement d'un outil de mesure de l'utilisabilité des intranets BIBAFull-Text 149-152
  Camille Grange; Henri Barki
This paper reports on an ongoing research project on intranet usability. Intranets are web-based information systems that are thought to boost employee productivity and improve organizational performance. For its part, usability is considered to be a key factor that influences the quality of computer-human interactions. The objective of the research is to develop and validate an instrument with which the usability of a given intranet can be measured. The present paper provides an introduction to the subject and the research problem. It also presents a synthesis of the literature on intranet usability and a research model for assessing it. The last section describes the methodological approach adopted for a study that is currently in progress, and the initial results obtained from the first round of the data collection.
ExploraGraph et la personnalisation des interactions pour l'apprentissage BIBAFull-Text 153-157
  Aude Dufresne; Sandrine PromTep
This paper describes how the different dimensions of personalization can be integrated in an environment designed to support learning. We show how the Explora-Graph environment integrates those various dimensions to restore a more holistic interaction.
Glyph 2: une saisie de texte avec deux appuis de touche par caractère -- principes et comparaisons BIBAFull-Text 159-162
  Franck Poirier; Mohammed Belatar
Glyph is a new version of the text entry method called Glyph. Glyph 2 is designed in order to make easier, more flexible and more rapid the text input. The main difference is that Glyph 2 uses only two keystrokes per character. As Glyph, the character input is based on a decomposition in basic shapes, according to a principle of analogy with Roman characters. The same set of primitives is used for Glyph 2, a minimal set of six primitives for coding a large set of characters. This paper presents the coding principle and the advantages of Glyph 2 compared to Glyph. Then, Glyph 2 is compared to other well-known text input methods.
Instrumentation de focus-group dans la co-conception de systèmes mixtes BIBAFull-Text 163-166
  Emmanuel Dubois; Cédric Bach; Guillaume Gauffre; Syrine Charfi; Pascal Salembier
This paper introduces and illustrates a process that integrates Focus-Group into early phases of a mixed systems design process. This process supports the systematic exploration of mixed interaction design solutions and offers a framework to present data collected in a Focus-Group. We also present a connection between this process and an existing tool for the design of mixed systems.
La cabine virtuelle d'immersion (CVI): un mode de transport des outils d'interaction dans les univers 3D BIBAFull-Text 167-170
  Thierry Duval; Alain Chauffaut
We try to explore a way to provide efficient tools to navigate and interact efficiently and in a generic way within 3D virtual universes. We propose a new concept: the Immersive Virtual Cabin, which defines the 3D workspace of the user, which allows to carry virtual tools for 3D interactions, and which is capable to adapt these tools to the changes of universes' scale. We try to show that navigation in 3D virtual universes is not only the change of a viewpoint, but also the move of the interaction space.
L'accessibilité des E-services aux personnes non-voyantes: difficultés d'usage et recommandations BIBAFull-Text 171-174
  Françoise Sandoz-Guermond; Marc-Eric Bobiller-Chaumon
While taking into account handicapped people in the design of technologies represents a social and political stake that becomes important (in particular with the recent law on equal rights for all the citizens, March 2004), this paper aims at evaluating the level of accessibility of two sites of E-services thanks to tests of use and proposing a set of recommendations in order to increase usability for the largest amount of people.
Mesures et rétroactions psychophysiologiques en immersion virtuelle: le cas des réponses oculomotrices et sexuelles BIBAFull-Text 175-178
  Patrice Renaud; Guillaume Albert; Sylvain Chartier; Marie-Pierre Bonin; Pascale DeCourville-Nicol; Stéphane Bouchard; Jean Proulx
This paper presents a new paradigm in sexual and perceptual motor psychophysiology. This paradigm is based on the integration of an immersive vault, sexual plethysmography, eye tracking and a device of mediated biofeedback.
Net-art, entre conflit et sensibilité de l'interface BIBAFull-Text 179-182
  Crispel Aude
The Net-art movement, whose origins can be traced back to Conceptual art, Fluxus, and Performed art, is based upon new problematic relationships between Man and his machine. Whenever the artists discover new plastic arts tools that newly-created relationship evolves all the way to bringing Man into the machine. Interactivity, sensibility or corporality that are part of Net-art interfaces recreate an aesthetics in which Man and the machine face one another, each claiming respectively a notion of existence. Is the Cyberpunk myth knocking on our door?
   From JODI to Mouchette, a human and technological generation separates two different worlds, ideologies and conceptions of Man and the machine. If the interfaces generated by the Net-art deal with various problems and cultural stakes, from the point of view of form, they reveal, above all, the intellectual interaction between the artist and his medium, from conflict to sensibility.
Pourquoi il n'est pas possible actuellement d'utiliser des objets pédagogiques plastiques respectant la norme SCORM BIBAFull-Text 183-186
  Antoine Bouyer; José Rouillard; Alain Derycke
In a context of multimodality and abstract interfaces, this paper shows problems related to the dynamicity of interfaces, through a case study. This one is applied to the distance learning field, which is very directed towards the traditional Internet. We show why, today, it is not possible to deploy concrete interfaces, at the same time based on a generic model, and usable on learning management systems respecting SCORM.
Qui parle?: comparaison d'indices pour identifier l'interlocuteur dans un monde virtuel BIBAFull-Text 187-190
  Sylvie Noël; Sarah Dumoulin
This paper describes a study comparing three types of cues to signal the speaker inside a virtual environment: a speech balloon above the speaker's avatar; the speaker's name on-screen; and a representation of the speaker inside a 2D map. People are able to quickly and correctly identify the speaker, no matter which cue is used. However, people recall the dialogue least when the cue is the speaker's name. This low recall might be explained by the interference of a semantic cue on a semantic task.
Qui est connecté avec qui?: personnalisation et séparation dans les communication appliances BIBAFull-Text 191-194
  Nicolas Masson; Wendy E. Mackay
Communication Appliances offer peripheral awareness among remotely located pairs or small groups of participants. Various media (image, sound, video) may be exchanged over a continuously-connected communication channel. We are interested in the problem of what happens when multiple communication appliances are connected, with multiple groups. What characteristics of Communication Appliances affect how users keep track of who is connected to whom? We developed the Com-Bar, a simple communication appliance, to act as a test-bed for comparing the effect of personalisation of exchanged images and separation across groups. Users made significantly more errors and took longer in the non-personalised and non-separated groups. However, adding either personalisation or separating the groups improved performance significantly, with optimal performance for non-personalised, separated groups.
Représentation focus+contexte de listes hiérarchiques zoomables BIBAFull-Text 195-198
  Eric Lecolinet; Duc Nguyen
Ordinary tree widgets do not make it easy to browse all the nodes of the hierarchy, thus reducing the performances for discovering or retrieving an object of interest. This paper presents a new visualization and interaction technique that tries to solve this problem by using a fish eye representation, semantic zooming and an interaction technique that is derived from Control menus. This technique makes it possible to browse the entire hierarchy by using a limited amount of mouse gestures.
Security and usability: the case of the user authentication methods BIBAFull-Text 199-203
  Christina Braz; Jean-Marc Robert
The usability of security systems has become a major issue in research on the efficiency and user acceptance of security systems. The authentication process is essential for controlling the access to various resources and facilities. The design of usable yet secure user authentication methods raises crucial questions concerning how to solve conflicts between security and usability goals.
Un système de visite virtuelle pour un bureau 3D BIBAFull-Text 205-208
  Johann Vandromme; Samuel Degrande; Patricia Plénacoste; Luciana Provenzano; Christophe Chaillou
In this paper, we propose a whole system to enable navigation inside a 3D object for a 3D desktop environment. It is made of a crystal ball, a map system and a guided visit. The "crystal ball" is used to contain and display the 3D object. This opens a space in the desktop while keeping its functionalities. The map system inspired from the World In Miniature helps the user to have a representation of the environment's topology. At last, a collaborative navigation is possible by allowing one user to guide another one.
Une interface plus intelligente pour SPHINX, un système d'aprentissage humain à partir d'exemples BIBAFull-Text 209-213
  Jalil Emmanuel; Laurence Capus; Nicole Tourigny
Sphinx is a computer environment to help human learning by means of examples in an introductory course of artificial intelligence. This interactive Web environment offers learners specific tools to help them explain the solved problems, alone or in collaboration with peers. Using Sphinx, learners can obtain from their peers or their teachers feedback on the produced explanations. In order to improve the interface between the learners and Sphinx, we added some functionalities for a better use of Sphinx by learners: personalization of the interface by the learner, selection of the examples by the system according to the learner's knowledge, intelligent guidance and advices by Sphinx. These new functions have been implemented and are presently under evaluation.
Vers des composants logiciels orientés tâches BIBAFull-Text 215-218
  Arnaud Lewandowski; Grégory Bourguin; Jean-Claude Tarby
Users' needs towards the environments supporting their activities are emerging and continuously evolve. A solution is to give the means to the users to adapt their environment, by integrating the tools they need. If technical solutions exist, current dynamic integration approaches still face a semantic problem: in order to finely integrate a tool in an activity, one must indeed well understand what will be its place in this activity. In order to facilitate this understanding and this dynamic integration, we propose a new approach of conception and integration, based on previous work on task modelling.
Visualisation interactive de données avec des points d'intérêt BIBAFull-Text 219-222
  David Da Costa; Gilles Venturini

Améliorer la conception des applications interactives par l'utilisation conjointe du modèle PAC et des patrons de conception BIBAFull-Text 225-232
  Thierry Duval; Jean-Claude Tarby
Software architectural models like MVC and PAC are now well known, and can be implemented in many different ways. This is a problem for students when they have to implement these models, because they do not know how to select an appropriate solution. For now several years we have proposed a methodology to facilitate the implementation of the PAC model. This methodology is mainly based on Design Patterns such as "Proxy", "Abstract Factory", and "Singleton". Thanks to this methodology, the structure of the source code is imposed and ensures an efficient separation between the application kernel and the GUI. Then, students learn to implement this separation efficiently, and they discover also with this separation that the software can evolve more easily: it is easy to change the GUI or the kernel without affecting the other part, and to add interaction possibilities to a non-interactive kernel.
Des hyperliens à la navigation par héritage application à la conception d'une web TV BIBAFull-Text 233-240
  Virginie Sans; Dominique Laurent
The increasing performance of networks allows today the display of TV news bulletin and others multimedia contents via an Internet connexion. We describe in this paper, a system called ARM which enables the integration of multimedia streamed contents into a web page. This system is composed of an XML based syntax language called ARM, that helps to describe multimedia presentation. The navigation between documents of the presentation is achieved through an inheritance principle. Our system is composed of a lecteur on the client side that handle the users interaction. The actual navigation process in multimedia presentations is mainly based on simple link and like HTML and multiple links like XLink. This approaches when medias are streamed didn't take into account a real fluid navigation. It is not possible, for example, to enlarge a region that displays a video without restarting this media from its beginning. The navigation by inheritance preserves the continuity of streamed medais according to the user's interactions. We also presents our application of this approach: a Web on demand TV.
Evaluation de la maquette d'un service multimodal de recherche d'itinéraire dans un réseau de bus BIBAFull-Text 241-244
  Marc Mersiol; Fanny Badia
The design and development of a multimodal application requires a time-consuming and expensive process. During design, hypothesis can be evaluated with mockups using the Wizard of Oz methodology. This paper presents some results issued from a user test conducted to evaluate a bus route and schedule application mock-up implemented in two versions: a monomodal (graphic) and a multimodal (graphic and vocal).

Logiciel d'annotation pour la conception de cours sur le web sémantique BIBAFull-Text 249-252
  Yan Bodain
Several tools are available to help authors make electronic annotations in Web pages. None of these tools are however adapted to the context of electronic course design. We present a Java application that allows authors (pedagogues, teachers) to design, create and publish HTML pages intended for the Semantic Web.
Une approche anthropocentrée interactive pour l'aide à la décision en marketing bancaire BIBAFull-Text 253-256
  Olivier Couturier; Engelbert Mephu Nguifo
This paper is focused on real banking marketing problem. It is based on association rules mining which is one main problem in knowledge discovery in databases (KDD). However, current methods is limited to extract some particular information and to restore it. Several works were proposed to solve it thanks to user-driven process. In this kind of approach, the whole KDD process is tackled and not only the mining step. KDD design integrates the user at the heart of the process by playing a role of evolutionary heuristic. This paper focuses on the role of the expert and explains his help within the process. We highlight in our works the HCI preponderant significance. Indeed, it merges tacit and explicit knowledge and good results are produced in our application.
Zone cours: un système de gestion de plans de cours normalisés BIBAFull-Text 257-261
  Jacques Raynauld; Olivier Gerbé
Still at the center of university teaching, syllabi, either in paper or electronic format (PDF, HTML), are not easily accessible to students or the general public. Moreover, the users interfaces and the vocabulary employed can vary across courses, an unnecessary hurdle for the users. HEC Montreal has successfully launched Course Zone (http://zonecours.hec.ca), a centralized model-based syllabi platform with a common users interface. Course Zone is now used in 90% of the courses offered.
Comparaison de deux méthodes pour implémenter la programmation sur exemple BIBAFull-Text 265-268
  Loé Sanou; Patrick Girard; Laurent Guittet
This paper describes two techniques of implementation that make it possible to record and replay Swing events. An analysis of user's interactions made it possible to define basic operations to implement: recording and replaying. The two proposed techniques lean on systematic recording of system events, and on components specialisation.

Implémentation par agents du processus d'adaptation des informations en interface homme-machine BIBAFull-Text 273-276
  Rohallah Benaboud; Zaïdi Sahnoun
One of the research domains in HCI refers to the techniques which make it possible to the users to perceive and to manipulate interfaces which answer their needs and preferences. Adaptive interfaces belong to these techniques. In order to implement this type of HCI, this paper presents a based agents architecture. In this architecture, the adaptation is seen as a solution emerging of agents. The proposed architecture implemented in our work using the JADE platform.

Exploiter des interfaces mobiles dans le cadre d'un travail collaboratif co-présent BIBAFull-Text 283-284
  Stanislaw Borkowski; Jérôme Maisonnaisse; Julien Letessier; James L. Crowley
With the advent of new display technologies, our working habits are likely to change. Tabletop displays and lightweight portable devices will diminish current spatial constraints, and allow new forms of computer assisted work. To anticipate this trend, it is necessary to explore new interaction scenarios based on mobile interfaces. In this video, we present an editing application in which a portable interface allows users to collaboratively author a presentation. We describe our approach to create projection-based mobile interfaces, and outline an ongoing experiment evaluating different interaction techniques for passing the control of a mobile interface.
Interactions humain-ordinateur porté via des interfaces diffuses BIBAFull-Text 285-286
  Nicolas Plouznikoff; Jean-Marc Robert
This demonstration first presents the wearable computer prototype used in our research, along with its various components. Then, we present examples of diffused human-wearable computer interfaces. Such interfaces make use of the environment and the task's artifacts and transform them into wearable computer peripherals. Interacting with the wearable computer thus means manipulating these entities.
K-MADe: un environnement pour le noyau du modèle de description de l'activité BIBAFull-Text 287-288
  M. Baron; V. Lucquiaud; D. Autard; D. L. Scapin
This demo concerns K-MADe, a tool for contributing to the incorporation of ergonomics into the interactive systems design process, through task and activity analysis. The originality of the tool is to be based on a model whose expressive power lies on a formal semantic. This facilitates task description and analysis, but also querying the model and migrating within models and software lifecycle steps.
