Equator: mixing media and showing seams BIBAKFull-Text 1
  Matthew Chalmers
The Equator interdisciplinary research collaboration has been exploring the combination of media such as mobile devices and collaborative virtual environments. We have built collaborative systems for a number of application areas including cultural heritage and tourism, performance, games, medical monitoring and environmental science. These systems have generally involved online visitors to a building or the city streets interacting with on-site visitors to the building or the streets. Sometimes the people online, using new media, are also on-site, using old media. Overall, Equator explores the interconnection and interweaving of activity in heterogeneous media which are usually treated in an isolated way. A number of higher-level design concepts have either motivated this work, or have arisen from experimentation with and evaluation of such systems. In this talk I offer my perspective on Equator's approach to ubicomp and HCI, giving examples of system designs, user experiences and conceptual work, and how they too are interconnected and interwoven in our research.

This paper describes the political environment in Belgium and in Europe regarding Web accessibility, it shows the importance of accessibility for visually deficient people and it briefly describes the technical aspects, i.e. the use of computers by a visually handicapped person and the principles of accessibility. It ends with the presentation of the concrete situation in Belgium, and the action of the BlindSurfer initiative.
Keywords: Belgium, BlindSurfer, accessibility, handicap, visual, website
Les leçons tirées des deux compétitions de visualisation d'information BIBAKFull-Text 7-12
  Jean-Daniel Fekete; Catherine Plaisant
Information visualization needs benchmarks to carry on. A benchmark is aimed at comparing information visualization techniques or systems. A benchmark is made of a dataset, a list of tasks mostly based on finding facts about the dataset, and a list of interesting or important findings about the datasets (the nuggets to find). For the second year, we are organizing the InfoVis Contest aimed at collecting results for benchmarks. We describe here the main lessons we learned.
Keywords: benchmark, contest, evaluation, information visualization
Couplage de ressources d'interaction BIBAKFull-Text 13-20
  Nicolas Barralon; Christophe Lachenal; Joëlle Coutaz
Although coupling interaction resources is key to ubiquitous computing, this notion has been overlooked in previous studies. In this paper, we address this notion in a more systematic way by describing coupling as a finite state machine whose states should be maintained observable and controllable by users in a flexible and reliable manner. We illustrate the discussion with state of the art demonstrators as well as with I-AM, a middleware that supports the dynamic construction of multi-screen, multi-keyboard, and multi-pointer interactive spaces.
Keywords: interaction resources coupling, interaction technique, ubiquitous computing
De la représentation de l'interlocuteur vers un modèle utilisateur formel pour le dialogue personne-machine BIBAKFull-Text 21-28
  Philippe Bretier; Ludovic Le Bigot; Franck Panaget; David Sadek
This paper proposes the formalization and implementation of user model. It is based on an interlocutor's model in natural language dialogue system. Experimental studies on interlocutor's representation and, particularly, on user's familiarization with the system were used for the results analyses. The analysis of the results has shown the more the user is familiarized the more he gives relevant information for research in his first utterances, and with the same number of words. The formalization proposed concerns (1) user's expertise or familiarization level, and (2) the detection of this level. The extended user model allows the system to adapt and thus, to contribute to increase usability and its efficiency in the information research processes.
Keywords: dialogue, interlocutor model, natural language, user model
Conception participative par « moments » BIBAKFull-Text 29-36
  Jean Caelen; Francis Jambon
This paper describes an approach for the participatory design. After describing the trends in the domain, a formalization of the design process is expressed based on ëphaseû, ëmomentû and ëprimitiveû. The phases articulate the design moments as nodes and transitions in a dynamic graph. The moments are built on reusable primitives defined as instanciable objects. Then, the paper details with this formal model a platform and tools for managing the design process on different points of view: from the user and engineers to the project manager.
Keywords: participatory design, platform for experiments
Modélisation de l'interaction collaborative dans les systèmes de Réalité Mixte BIBAKFull-Text 37-44
  René Chalon; Bertrand T. David
This paper deals with the problem of interaction modeling in Mixed Reality (MR) systems. After reviewing existing HCI models, and pointing out their limits in MR context, we present our model called IRVO (Interacting with Real and Virtual Objects) which aims to help to design MR systems. Then we propose taxonomy for MR systems based on IRVO model. Finally, we investigate the utility of the model for the design phase, and we show how it links to other HCI models.
Keywords: augmented reality, collaborative work, interaction model, mixed reality
Vers des outils pour les équipes de conception d'interfaces post-WIMP BIBAFull-Text 45-52
  Stéphane Chatty; Stéphane Sire; Alexandre Lemort
Programming highly interactive user interfaces remains a complex task with the available software tools. Interviews and observation of 50 design or production teams of industrial products shows the importance of group production between graphics designers, programmers, usability experts and the lead designer. Tools must allow each of them to efficiently produce their part. That imposes new constraints on the architecture of interactive software. We present the solutions used our development suite, Intui-Kit, designed to bridge the gap between interface design and software engineering. We illustrate it on a concrete product development.
Composant logiciel vs physique pour interagir avec un espace de valeurs temporelles BIBAKFull-Text 53-60
  Chaouki Daassi; Laurence Nigay; Marie-Christine Fauvet
Timelines are recurrently used to design visualization techniques of temporal data. In this paper, we present our perspective wall timeline to visualize temporal values. We illustrate how our timeline could be used by two examples of visualization techniques of temporal data: the star representation technique and the superposed histograms technique.
   In this paper, we propose to use a dedicated physical device for the perspective wall timeline, making the reusable corresponding software component a reusable physical device. Then, we present the results of an experiment we have conducted to compare the time device to the timeline (software component). Finally, we conclude and present our perspectives.
Keywords: evaluation of user interfaces, physical device, temporal data visualization, timeline
Un modèle préliminaire du domaine des systèmes mixtes BIBAKFull-Text 61-68
  Emmanuel Dubois; Benoît Mansoux; Cédric Bach; Dominique Scapin; Guillaume Masserey; Joël Viala
This paper describes a multidisciplinary approach to the modelling of the mixed reality systems domain. Such modelling, useful for structuring such a recent interaction domain, and to facilitate design and evaluation from both software engineering and ergonomics perspectives, is based on the combination of two approaches: the ASUR notation and an ergonomic recommendations-based model. Both approaches are presented as well as the results of their combination. The resulting model, an extension of the ASUR notation, is described as well as its limits and perspectives.
Keywords: ASUR notation, domain model, ergonomic recommendations, mixed systems
La boîte à outils InfoVis BIBAKFull-Text 69-76
  Jean-Daniel Fekete
This article presents the InfoVis Toolkit, designed to support the creation, extension and integration of advanced 2D Information Visualization components into interactive Java Swing applications. The InfoVis Toolkit provides specific data structures to achieve a fast action/feedback loop required by dynamic queries. It comes with a large set of components such as range sliders and tailored control panels required to control and configure the visualizations. These components are integrated into a coherent framework that simplifies the management of rich data structures and the design and extension of visualizations. Supported data structures currently include tables, trees and graphs. Supported visualizations include scatter plots, time series, Tree-maps, node-link diagrams for trees and graphs and adjacency matrix for graphs. All visualizations can use fisheye lenses and dynamic labeling. The InfoVis Toolkit supports hardware acceleration when available through Agile2D, an implementation of the Java Graphics API based on OpenGL, achieving speedups of 10 to 1000 times.
Keywords: advanced interaction, graphics, information visualization, toolkit
Comparaison de la lisibilité des graphes en représentation noeuds-liens et matricielle BIBAKFull-Text 77-84
  Mohammad Ghoniem; Jean-Daniel Fekete; Philippe Castagliola
This article describes a taxonomy of tasks on graphs and a controlled experiment for assessing the readability of two graph representations: matrices and node-link diagrams. The experiment only concerned a subset of the described tasks but provides important insights on the use of representations depending on the graph sizes and densities. It shows that, for graphs larger than 20 nodes or sufficiently dense, most tasks are performed more efficiently on the matrix-based representation. Only some path related tasks score better on node-link diagrams.
Keywords: adjacency matrices, evaluation, node-link representation readability, visualization of graphs
Svalabard: une table à dessin virtuelle pour la modélisation 3D BIBAKFull-Text 85-92
  Stéphane Huot; Cédric Dumas; Gérard Hégron
This paper introduces a perspective sketching interface for creative 3D modeling: Svalabard. To close the gap between designers' abilities and 3D modeling tools, our proposal is a freehand sketching tool, metaphor of a drawing desk. Interactions and tools take advantage of designers work habits (multilayer drawing, association of interactions with input devices). Svalabard includes background drawing filters, developed from a user study in the architectural domain. Those filters detect the current drawing context in real-time to adapt the interface and clean the sketch. Finally, the result of the filters is a structured representation of drawn 3D volumes.
Keywords: 3D modeling, contextual interaction, creative design, perspective sketch, sketching interfaces
Aides électroniques pour le déplacement des personnes non-voyantes: vue d'ensemble et perspectives BIBAKFull-Text 93-100
  Christophe Jacquet; Yacine Bellik; René Farcy; Yolaine Bourda
In this paper, we present an overview of current electronic locomotion aids for the blind and perspectives for future systems. We start with the two main issues raised by locomotion assistance for the blind: how to capture and present information. Then, we explain how these issues have been dealt with in existing devices, and we describe the techniques that have been used to solve them: infrared, ultrasonic and laser sensors to capture information; tactile and audio modalities to present information. After that, we expose some current ideas and results about a new generation of context-aware, semantics-enhanced locomotion assistance devices, that are expected to provide higher-level information than current ones do.
Keywords: autonomy, blind People, context-awareness, electronic travel aids, locomotion assistance

Vers une interface multimodale pour une assistance à la conception architecturale BIBAKFull-Text 109-116
  Pierre Leclercq; Geneviève Martin; Catherine Deshayes; François Guena
This paper relates a multidisciplinary research about the specification of a multimodal interface for architectural design. After three recollections concerning the characteristics of a design process, the functionalities of existing CAD tools and the scientific experience of multimodal HCI, the paper presents the observations made from an original experiment about the analysis of the designer's graphical, vocal and gesture activity. The paper then suggests operational specifications for a creative HCI for architects.
Keywords: activity analysis of an architectural design, multimodal human computer interaction (drawing / gesture / speech)

The DESTINE tool is conceived in order to evaluate the usability of web sites. Evaluation is made automatically for a set of guidelines, and manually for non automatisable guidelines. DESTINE covers some steps of the evaluation task, from the context specification to the finalization and the communication of the evaluation report.
Keywords: automatic and manual evaluation, guidelines, web usability
Caractéristiques, enjeux et défis de l'informatique portée BIBAKFull-Text 125-132
  Nicolas Plouznikoff; Jean-Marc Robert
This article presents an overview of the characteristics, issues and challenges of wearable computing. Wearable computers are worn on the body. They possess four fundamental characteristics setting them apart from traditional computing devices: they are mobile, constantly available, (pro)active and can be used in a relatively transparent way. Their role is to assist a user who moves about while accomplishing real-world tasks. Since they are carried by the user and must face severe constraints of weight, size, seamless use, etc., their interface has a definite impact on user acceptability, and eventually on human performance and satisfaction. We analyze the characteristics of various input and output peripherals, and their impacts on human perception and cognition. We then emphasize the inadequacy of the peripherals and interaction mechanisms of traditional computers for wearable computers. Finally, we give several examples of tasks and application domains that could make good use of wearable computers.
Keywords: human-computer interfaces, mobile computing, wearable computer

  Igor Schadle; Franck Poirier
This article presents Sibyl, an AAC computer based system for people with severe motor impairments. The system is a virtual keyboard using scanning for key's selection. To allow faster typing, the system integrates linguistic knowledge which acts on two levels: first, a prediction of letters to facilitate access to letter, then a prediction of words to save the number of keystrokes.
Keywords: alternative and augmentative communication, degraded interaction, linguistic prediction, text input, virtual keyboard
Utilisation du modèle PAC-Amodeus pour une réutilisation optimale de code dans le développement de plusieurs versions d'un logiciel commercial BIBAKFull-Text 149-156
  Frantz Degrigny; Thierry Duval
We have developed Zoé, a software solution dedicated to CVs' management. In order to ensure its strongly graphical and interactive aspect we have used the PAC-Amodeus Software Architectural Model for GUIs. This approach allowed us to very quickly and easily develop a simplified version of this software: Léa. After a brief reminder on the PAC-Amodeus model we give indications on how to implement it efficiently in the context of a large program (more than 2000 classes) written in Java, a programming language which allows only simple inheritance.
Keywords: design patterns, efficient implementation of software architectural models, software architectural models for GUIs, software engineering methods for GUIs

Une expérience de conception et de prototypage d'interfaces évoluées en milieu industriel BIBAKFull-Text 165-172
  Céline Schlienger; Stéphane Valès; Stéphane Chatty
Iterative design methods are barely applied for complex system programming in the industry. However, more and more manufacturers become aware about products usability and try to find solutions for designing prototypes.
   IntuiLab has integrated participatory and iterative design methods in the industrialisation process of complex systems. It has adapted them to meet industrial constraints. We present the adaptation of these methods and, with a concrete example of prototyping for a traffic control industrialist, we illustrate how they were implemented.
Keywords: advanced interfaces, industry, iterative design, methods, process, prototyping

EsQUIsE-SMA: un système multi-agents pour l'interprétation d'esquisses architecturales BIBAKFull-Text 179-180
  Roland Juchmes; Pierre Leclercq
Architects use freehand sketches in the initial stages of their design work because they prove to be the best adapted media for handling and expressing their preliminary ideas. Therefore, to help designers in their inventive work, a means for inputting and interpreting their sketches was needed.
   We propose a multi-agent approach to attain that goal. In this paper, we describe the operations of a multi-agent system for the on-line recognition of sketches. This system is currently integrated into the EsQUIsE prototype, a demo program for inputting, analysing and interpreting architectural design sketches.
Keywords: computer aided design, hand-drawn sketch recognition, human-computer interface, multi-agent systems

  Frédéric Vella; Nadine Vigouroux; Philippe Truillet
This paper describes the principles which underlay the specification of SOKEYTO soft keyboards design platform. This one offers functions of specification (prediction model, spatial organization, input code). It also integrates neurophysiologic models useful for usage predictive evaluations goals. A XML description of keyboard is generated.
Keywords: design environment, keys layout, neurophysiologic models, soft keyboards
De la visualisation à la manipulation directe d'information avec ILOG discovery BIBAKFull-Text 183-186
  Thomas Baudel
Nowadays generic database systems (such as accounting and financial software, customer relationship management systems, logging and tracking software...) provide mostly forms and menu based interfaces that do not take advantage of the graphic and interactive capabilities of current hardware. This is because the data they handle does not have intrinsic visual representations upon which direct manipulation principles could be used. This article presents how we have extended an information visualization framework which allows to create and to interactively transform easily rich data views, with generic data manipulation functions tuned to take advantage of each view's characteristics. These editing capabilities enable us to generalize the mechanisms of direct manipulation to address all sorts of massive abstract data manipulation needs.
Keywords: database user interfaces, direct data editing, direct manipulation, information visualization
DoPIdom: une boîte à outils pour la conception d'interfaces centrées sur les documents XML BIBAKFull-Text 187-190
  Olivier Beaudoux
The concept of document usually refers to data that documents contain, but rarely with actions that documents can handle. As a consequence, it is hard to specify how users can interact with documents: this is mainly done with dedicated applications that users have to juggle in order to achieve a single editing task. This paper presents DoPIdom, a user-interface toolkit designed to create interactive environments centered on XML documents. It is based on the DPI (Document, Presentation, Instrument) model, which aims at hiding the concept of application from the user point of view.
Keywords: GUI toolkits, document model, interaction model, software components
Proposition pour une gestion dynamique de l'inter-activités dans le TCAO BIBAKFull-Text 191-194
  Grégory Bourguin
Using some results coming from human and social sciences, we are working on the still important problem of tailorability inside CSCW systems. Our proposition aims at favouring the dynamic integration of groupware systems in a global and integrated environment that creates a context for their use. This work leads us to define the problem of the inter-activities management. This study helps us to propose a technical solution to this problem and that is realized in the CooLDA platform.
Keywords: CSCW, groupware, integration, interactivities, tailorability
Palette hyperbolique: un outil pour interagir avec des ensembles de données BIBAKFull-Text 195-198
  Kamel Chelghoum; Maurice Margenstern; Benoît Martin; Isabelle Pecci
Manipulations and exploration of large data sets are common problems. This paper aims at adapting a fisheye technique that uses hyperbolic geometry. Unlike the classical approach, the hyperbolic space used in our research is tiled. The tiling method proposed supplies a code for data that ensures the neighbourhood between data. The difficulty lies in finding how to distribute data through the tiling. We give some heuristics to better target suitable data sets. Our research results in defining an interactive tool for manipulating such data sets: the hyperbolic palette. To illustrate the various possibilities of this tool, a prototype application was developed. Its goal is to provide a new palette to select a colour out of 16 million options. We show in this paper why such an application fulfills our heuristics to use an hyperbolic palette.
Keywords: fisheye view, hyperbolic geometry, large data spaces, visual exploration
L'architecture logicielle UMR pour les interactions multicanaux et multimodales avec les e-services BIBAKFull-Text 199-202

Construction d'un modèle comportemental pour le travail coopératif capillaire BIBAKFull-Text 207-210
  Olivier Delotte; Bertrand David; René Chalon
This article describes a method for the design of a behavioural model of a collaborative capillary system elaborated from a set of scenarios of use. Our approach allows reusing collected scenarios and creating new scenarios which can be integrated in the behavioural model. The model is actors, centred, i.e. their preferences have been take into account before and during the use. We detail our CBME tool (Co textualized Behavioural Model Environment) which aim is to visualize and manage different elements of the model and to assist the designer in its construction.
Keywords: CSCW, MDA, adaptation, context of use, scenarios

Visualisation d'informations boursières sur téléphones mobiles BIBAKFull-Text 215-218
  Custinne Grégory; Monique Noirhomme-Fraiture; Chittaro Luca
This paper presents new methods for visualization of stock exchange data on mobile telephones. Considering the very reduced size of a mobile telephone screen, its weak resolution and the great volume of data to be represented, we suggest condensing the information beforehand. The data are first treated with a standard technique of classification before their visualization. For visualization, we propose two methods of traditional representation (Bar Chart and Table) and two more recent methods (Pixel Bar Chart and Spirale).
Keywords: clustering, mobile phone, visualization

IHM et SIAD: vers une composition d'outils interactifs pour l'aide à la prise de décision BIBAKFull-Text 227-230
  Sophie Lepreux; Christophe Kolski; Mourad Abed
Decision making is always a topical problem. In order to take a decision in complex problem, the user needs some criteria. In general, one tool gives one analysis following one criterion. Moreover, no tool gives one analysis for all criteria. This paper presents a DSS design method. The goal is to make some analysis following several criteria in combining several tools. This method has been applied to investment in railway domain. The issues concerning the interface composing for the decision making will be presented.
Keywords: HCI, component-based development (CBD), decision support system (DSS)
TrackMouse: une solution 4D pour des interactions avec deux curseurs BIBAKFull-Text 231-234
  Benoît Martin
Desktop applications are more and more sophisticated. Often, the user needs several degrees of freedom to accomplish his task. One solution is to provide two independent cursors for some types of interactions but this solution is mainly used in two-hands interactions. The objective of this paper is "one user, one hand, two cursors". We propose the TrackMouse, a multimodal input device for interactive applications based on the simultaneous use of two cursors. It is an evolution of the Logitech force feedback mouse by adding a trackball to offer the degrees of freedom needed to control the second cursor. To manage the TrackMouse, an API for Windows XP is described too. Thus, a sample of application shows some new possible interactions.
Keywords: multi modality, multiple cursors interactions, multiple mice systems
Communiquer par groupes avec Circa BIBAKFull-Text 235-238
  Emmanuel Nars
Over the recent years, the number of communication applications available has greatly increased. However, functional redundancies and incompatibilities have made the use of these applications more and more cumbersome. In this paper, we present Circa, a software infrastructure designed for personal communication with close relations by way of groups. Circa provides users with a simple and unique interface to manage groups of individuals, independently from applications. Circa also facilitates the implementation of communication applications by taking care of the low-level details related to data transmission and storage.
Keywords: communication appliance, groups, infrastructure, toolkit
VisuThread: un module de visualisation de conversations électroniques BIBAKFull-Text 239-242
  Benoît Otjacques; Fernand Feltz
Electronic messaging has become one of the most widely used software in the enterprises. Increasingly its usage goes beyond the scope for which it was initially designed. For instance, the users consider it as a tool supporting the management of their tasks. The inappropriateness of current e-mail clients becomes more and more patent. Several research works have studied how to enhance its functionalities, especially in the domain of graphical representation of information. This paper describes 'VisuThread', a conversation visualization module integrated in an electronic messaging client. The proposed graphical representation aims to allow a rapid apprehension of the current state of a conversation. It highlights the chronological succession of messages as well as the participants to the conversation. Moreover, additional useful functions are also integrated, such as filtering, zooming, or access to the message editor.
Keywords: electronic messaging, graphical representation, thread visualization
Une interface conversationnelle pour les agents assistants appliqués à des activités professionnelles BIBAKFull-Text 243-246
  Emerson Cabrera Paraiso; Jean-Paul A. Barthès
This paper describes the design of a speech and natural language dialog interface for personal assistants. We are specially interested in working with personal assistants in professional domains. We believe that the use of speech will facilitate the interaction between human and machine, since the user may speak with the agent using her own terms, increasing the quality of the assistance. The main difficulty in our approach however is to handle spoken natural language, and to understand its actual context. To overcome such difficulties, we restrict the exchanges to Directives Speech Act classes: inform, request, or answer.
   We present a conversational speech interface architecture in a multi-agent system applied to personal information management. As a clear result, we expect an increase in the quality of the interface and of the assistance to the user, which seems to be the case on preliminary results.
Keywords: assistant agents, dialog systems, natural language, ontology, speech interface
Une description probabiliste de la communication parlée entre homme et machine BIBAKFull-Text 247-250
  Olivier Pietquin
This paper presents a formalism for the description of man-machine spoken communication in the framework of spoken dialogue systems. This formalisation is based on a probabilistic description of the interaction and of the information processing occurring in each module composing a spoken dialogue system. Eventually, some possible applications of this theoretic framework to the problem of dialogue systems' design are proposed.
Keywords: natural language processing, speech processing, spoken dialogue systems
Une architecture de dialogue basée sur un modèle pour les applications web BIBAKFull-Text 251-254
  Florence Pontico; Christelle Farenc; Marco Winckler
The navigation is one of the most critical aspects of web applications since it supports most of user interaction. Even though navigation models may help designers to deal with complex and large web applications the modelling itself cannot ensure its correct implementation. This paper presents a MVC architecture which employs abstract navigation models (built with the SWC notation) to implement the effective navigation made available to the users.
Keywords: dialog control, navigation modelling, web applications
Modèle d'architecture pour la conception de systèmes multimodaux en sortie BIBAKFull-Text 255-258
  Cyril Rousseau; Didier Bazalgette
Output multimodality consists in presenting information to the user in an "intelligent" way by exploiting different communication modalities. This presentation must be the most suitable to the interaction context. In this paper, we present a global architecture framework to support output multimodal systems design and more precisely mechanisms tailoring the information presentation according to the interaction context. Two applications of this architecture framework (mobile telephony and military avionics) are also presented.
Keywords: human-computer interaction, interaction context, multimodal system, output multimodality
Vérification de règles ergonomiques sur un modèle de navigation des applications web BIBAKFull-Text 259-262
  Joseph Xiong; Christelle Farenc; Marco Winckler
If Web usability guidelines can play an important role for ensuring usability when designing and evaluating web application, the moment and the way to use them still remain unclear. This paper presents a preliminary study and a classification of ergonomic rules about web applications navigation. Secondly, we describe our approach to apply these rules directly to a navigation model (SWC).
Keywords: SWC, ergonomic rules, evaluation, navigation modelling, web applications

The goal of this study is to apprehend the perceptive training capacities of a human subject via an artificial device and to also underline their limits and constraints. The principal constraint considered here, is the acuity in other words, the spatial proprieties ratio of the sensor and the explored objects. The experimental device couples the pen of a graphics tablet with tactile sensory stimulators. A matrix of virtual receptor field linked to a stylus by means of an equipped computer is responsible for the stimulator activation. The results show: i) that the subjects are able to perceive forms via this artificial device and that this perception is forced by the spatial resolution of the sensor, ii) That the subjects are able to adapt their movements to perceive very small forms (0,5 mm height), iii) To develop new exploration strategies.
