Perspectives sur le contexte

Une formalisation du contexte dans les environnements coopératifs nomades BIBAKFull-Text 1-8
  Manuele Kirsch-Pinheiro; Marlène Villanova-Oliver; Jérôme Gensel; Hervé Martin
In this paper, we propose an object oriented model for describing a mobile user's context inside a Web-based groupware system. These systems are confronted to the growing use of mobile devices, such as laptops, PDAs or cellular phones, which requires special context-aware capabilities. Our model formalizes the context notion, decoupling context and system information, which consequently reduces the system development complexity. We consider the context as a set of basic elements that identify the circumstances in which the user is accessing the system. These elements include elements related to physical aspects (the user's location and device), as well as those related to the cooperative process in which the user is involved (group, role, activities, etc.).
Keywords: context-aware systems, cooperative work (CSCW), mobile computing
Définition du contexte: fonctions de coût et méthodes de sélection BIBAKFull-Text 9-12
  Stéphane Lavirotte; Diane Lingrand; Jean-Yves Tigli
This paper targets with applications running on mobile devices. We aim at developing a formalism and a framework to simplify the development of applications taking into account the context in which they are running.
   Following previous studies from other authors, we extend the notion of context area using distance function with cost function on context space dealing on different modes of selection.
   We extend the context area formalism to encompass more applications. We demonstrate on a mobile applications: the museum visit.
Keywords: context-aware, defining model, definition of context, distance and cost functions
Définition et représentation du contexte pour des agents sensibles au contexte BIBAKFull-Text 13-16
  Oana Bucur; Philippe Beaune; Olivier Boissier
Developing context-aware applications needs facilities for recognizing and representing context, reasoning on it and adapting to it accordingly. In what concerns context representation, the newest and most challenging representation is the ontological one. The problem is that current ontologies for context are quite simplistic and do not provide a standard for representing complex context attributes. In this paper, we propose a context definition and representation used to construct a context-based agent architecture. The representation we propose combines the generality provided by ontologies with the complexity inspired by the object oriented models. The goal of the proposed representation is to support the deployment of context-aware agents able to learn how to recognize and adapt to the context of their decisions.
Keywords: context ontology, definition of context
Architecture d'agent sensible au contexte pour la prise de décisions BIBAKFull-Text 17-20
  Oana Bucur; Philippe Beaune; Olivier Boissier
Sensing, managing and representing context are necessary capacities for ubiquitous computing applications, moreover, their components must also be able to reason and adapt their behavior to the evolution of their physical and social environment. This paper proposes a multi-agent architecture consisting of context aware agents able to learn how to discern relevant from non relevant context on one hand, and to make appropriate decisions based on it on the other hand. This multi-agent system interacts with a context manager layer, which is able to answer context-related queries by using an ontological representation of context. The use of this architecture is illustrated on a test application for agenda management, using the JADE-LEAP platform on PCs and PocketPCs.
Keywords: context, learning, multi-agent systems

Capture du contexte et localisation

La localisation en intérieur à l'aide de répéteurs GPS vers un système de positionnement universel? BIBAFull-Text 21-28
  Nel Samama; Alexandre Vervisch-Picois; Marc François
The need for indoor positioning is obviously increasing with the emergence of navigation applications [1]. Many techniques are available or under development, but are very often specific to indoors. Currently, there is no technique that is applicable outdoors as well as indoors with good enough accuracy, and this is the point we are giving a solution to. The mobile network communication approach (GSM or UMTS with E-OTD and O-TDOA) does not provide as good accuracy as one would like: the typical requirement is between one meter and some tens of meters, depending on the application. Specific techniques for indoor positioning (Ultrasound, Bluetooth, UWB, etc.) achieve much better accuracy values, but are limited to indoor environments.
   Current works on indoor satellite-based positioning are addressing Assisted-GPS or pseudo-satellites (pseudolites) [2], [3], [4]. Our technique is different, since it uses GPS repeaters that transmit outdoor signals to indoors [5]. The main advantages of the repeater solutions are the simplicity of the repeaters' hardware and the need for only "software" upgrades for the GPS receivers, both allowing cost effectiveness and cheap deployment.
Localisation intra-bâtiment multi-technologies: RFID, wifi et vision BIBAKFull-Text 29-35
  Matthieu Anne; James L. Crowley; Vincent Devin; Gilles Privat
Indoor location-based applications have strong precision and scalability requirements that usually cannot be met by any single location-sensing technology. Combining the strong identification of RF-based location sensing with the accuracy of computer vision-based-tracking provides a powerful new solution for multi scale and multi-target indoor location sensing, without requiring dedicated infrastructures.

Une architecture hybride pour i'interrogation et i'administration des capteurs BIBAFull-Text 37-44
  Levent Gürgen; Cyril Labbé; Vincent Olive; Claudia Roncancio
Sensors have been successfully applied in many fields namely, military, house automation, medical and urban environments where they make information omnipresent. However, much work needs to be done on administration and querying sets of sensors. This paper presents an architecture for management of data streams coming from heterogeneous sensors. Our proposal is inspired by two traditional approaches. The first one is based on networks of "intelligent" sensors allowing data processing in a strongly distributed way. The second approach manages continuous data streams using a centralized or slightly distributed platform. We propose a hybrid approach combining the advantages of current approaches in order to build scalable solutions.
Une infrastructure à composants pour des applications ubiquitaires BIBAKFull-Text 45-48
  Areski Flissi; Christophe Gransart; Philippe Merle
Multiplication of mobile devices and generalized use of wireless networks imply changes on software applications design and execution. This new challenge is now called ubiquitous computing. In this paper, we present a software infrastructure dedicated to ubiquitous contextual services. They are designed as assemblies of distributed software components and are dynamically discovered according to end-users' physical location and device capabilities and automatically deployed on it. We have implemented this software infrastructure and an example of service on top of the OMG CORBA Components Model and the OpenCCM open source platform.
Keywords: CCM, distributed mobile components and objects, middleware, ubiquitous computing

Jeux et mobilité

Les usages émergents d'un jeu multijoueurs sur terminaux mobiles géolocalisés: les conséquences interactionnelles des "rencontres d'écran" BIBAKFull-Text 49-56
  Christian Licoppe; Yoriko Inada
This communication a case study about the uses in Japan of a multiplayer location aware mobile game. The gameplay is a collection game where users must gather sets of "virtual" objects. This case study of a commercially available location-aware multiplayer game provides a glimpse of what the experience of inhabiting an augmented urban public space might be like, and of the kind of social order and emergent "form-of-life" that might characterize it.
   The key feature is an onscreen map which features geo-localized players and virtual objects within a radius of 500 meters. This interface allows players to "see" one another onscreen. We analyze the interactional conventions that develop through such mediated encounter. How can "seing" one another in this way, and the geographical proximity it entails, become a pretext to start text-messaging exchanges. We discuss how such encounters involving mutual perception on the screen of the mobile phone are embodied, by analyzing the work users occasionally accomplish to realign their onscreen perspective with their embodied one.

Synchronisation dans les jeux multijoueurs sur téléphone mobile BIBAKFull-Text 57-60
  Sophie Chabridon; Christophe Kodrnja
This articles surveys some of the synchronisation techniques in use in multiplayer games on the Internet or on local networks to lessen the effects of latency. These solutions must be revisited with respect to the additional constraints encountered in mobile environments, i.e. a higher latency than in wired networks, but also a fluctuating connectivity that may lead to involuntary disconnections, and lightweight mobile terminals with limited computing capacity. Some experimentations using the Java toolkit for mobile phones (J2ME) are planned after this preliminary study to compare and evaluate several solutions.
Keywords: consistency, disconnection, latency, multiplayer game, synchronisation
GASP: un intergiciel pour les jeux en réseaux multijoueurs sur téléphones mobiles BIBAKFull-Text 61-64
  R. Pellerin; F. Delpiano; E. Gressier-Soudan; M. Simatic
This paper describes an ongoing work. We are designing and implementing a library of services dedicated to multiplayer on-line games for mobile phones. This library, called GASP, conforms to Open Mobile Alliance (OMA) v2.0 specifications. It is implemented in Java and offers a server and a client part. The latter is defined for MIDP 2.0 and DOJA 1.5 J2ME profiles. GASP v1.O implements partially OMA specification: We are working on a new version more complete.

Séreté et Continuité de services

Détection de partition pour la gestion de groupes en environnement mobile BIBAKFull-Text 65-72
  Muhammad Usman Bhatti; Denis Conan
Wireless networks are more ubiquitous than before and they present a whole new set of problems with their inception. Disconnection is one of such problems where mobile terminals can disconnect. Failure is another problem that is inherited from the distributed systems. The two may create partitions in the distributed systems which are necessary to be detected for fault tolerance in mobile environments. In this work, we present a partition detection service which is interoperable with group communication systems. The main idea of our proposition is to allow clients of the partition detection service to make the distinction between the nodes that are faulty and the ones that are only partitioned or disconnected.
Keywords: disconnection, fault tolerance, group management, mobile computing, partition
Sûreté de fonctionnement d'applications nomades construites par assemblage de composants BIBAKFull-Text 73-80
  Audrey Occello; Anne-Marie Dery-Pinna
Mobile handheld devices allow mobile users to use application services without taking care of their position. In this context, mobile applications must cope with service continuity during network disconnections. On the other hand, component platforms provide mechanisms to adapt applications by modifying component assemblies and to control these adaptations dynamically. However, these platforms are dedicated to traditional environments and do not take into account assembly breaks resulting from disconnections. In this paper, we propose to handle disconnections as assembly adaptations in order to determine whether work around components are useful. We extend the Satin model, created to control component assembly adaptations, so as to control nomad component disconnections.
Keywords: component assembly, disconnections, policy verifications
Une approche pour une continuité de service pour les utilisateurs de terminaux mobiles BIBAKFull-Text 81-88
  Nicolas Le Sommer; Hervé Roussain
In this paper, we present an approach to provide owners of mobile devices with ubiquitous services. This approach relies on a context-aware deployment of adaptive services on mobile devices and on the collaboration of these devices. These services are designed to provide all (or a part) of the functionalities of the services offered by infrastructure networks equipped with a wireless extension. This approach aims at cutting off from the connection constraints binding mobile devices to the access points of infrastructure networks, and thus to make it possible to use services autonomously. In this paper, we also present the platform we have implemented in order to validate our approach and some examples of adaptive services that have been deployed on it.
Keywords: adaptive services, context-awareness, deployment, mobile networks

Séreté des données

Sécurisation des flux multimédia adaptables: proposition d'un schéma de signature sur des proxies BIBAKFull-Text 89-92
  Ahmed Reda Kaced; Jean Claude Moissinac
In this paper, we present a secured multimedia content delivery system that aims to deliver an end-to-end authenticity of original content exchanged in an heterogeneous network while allowing content adaptation by intermediary proxies between the content providers and the final users. We proposed a system prototype applicable to multimedia content meta-data written in XML, in which the signature of the documents rests on W3C XML Signature standard.
Keywords: content adaptation, digital signatures, multimedia security
Authentification par la méfiance dans les systèmes pervasifs BIBAKFull-Text 93-96
  Rachid Saadi; Jean Marc Pierson; Lionel Brunie
We present in this paper a solution to the difficult problem of authentication in pervasive environments. The distrust model developed hereafter allows a particular site to accept inbound connections from foreign unknown users, and to bound their access to a certain level in its own organization.

Sauvegarde coopérative entre pairs pour dispositifs mobiles BIBAKFull-Text 97-104
  Ludovic Courtès; Marc-Olivier Killijian; David Powell; Matthieu Roy
We present the features of a collaborative backup service for mobile devices. This service relies on collaboration among peers in order to provide data backup and recovery. We identify the expected dependability properties for such a service. We then survey peer-to-peer collaborative backup systems described in the literature and identify mechanisms relevant to the mobile environment. We conclude on the specificities of this environment and identify future research directions.
Keywords: collaboration, data back-up, mobile applications, peer-to-peer
Data distribution platform for multimedia mobile applications BIBAKFull-Text 105-109
  Marcel Cremene; Michel Riveill; Iulian Benta
The new mobile access solutions are more valuable especially due to multimedia applications available anytime and anywhere. A problem is that the user needs to manage not only his own data but also the terminal limited memory and the available networks in conditions of a high terminal and network diversity, offering different quality for different prices. In this paper, we propose a platform that helps the user to optimize data management by data balancing between a mobile client and a fixed server. The goals are: increase the data availability, reduce the transport costs and duration and avoid filling the entire terminal memory. The decisions are made by a neural-fuzzy expert system.
Keywords: QoS and transport costs, distribution, expert system, fuzzy logic, mobile devices, multimedia data, network diversity

Le Web en contexte

Adaptation des applications au contexte en utilisant les services web BIBAKFull-Text 111-118
  Tarak Chaari; Frédérique Laforest; André Flory
The SECAS Project (Simple Environment for Context Aware Systems) is interested in the adaptation of applications to the context (preferences and environment of the user, used terminal ...). We aim to develop a platform which makes the data, the services and the user interface of applications adaptable to the various context situations. In this domain, researches have concentrated on how to capture context data and to carry it to the application. Our work focuses on the impact of context on the application. In this paper, we present the architecture of SECAS, a new definition of the context, our adaptation strategy and a case of study in the medical field.
Keywords: adaptation, context-awareness, pervasive computing, web services
Analyse empirique de l'inter-utilisabilité d'un service multisupport Web et téléphone BIBAKFull-Text 119-127
  Laurent Karsenty; Valérie Botherel
This report presents the results of an empirical analysis of a multi-device service which is accessible both from a Web interface on a PC and a spoken interface over a telephone. The objective of this study was to deepen our understanding of inter-usability issues related to multi-device services. Inter-usability is defined as the easiness with which users transfer and adapt the knowledge they have acquired from previous uses of their service while they access it with a new device. The results of this study, obtained from a sample of 20 users achieving a series of use scenarios, highlights the need to keep data, functions and use procedures as consistent as possible between the various devices but reveals, at the same time, inter-device inconsistencies that are not detrimental to the dialogue quality and even, in some cases, desirable. These results stress the relevance of user's activity analysis in designing multi-device services and suggest some basic principles that may drive their design.

Prise en compte du contexte dans l'étude des applications multimodales sur téléphone mobile BIBAKFull-Text 129-132
  Marc Mersiol
This paper describes two usability tests conducted on a multimodal application. This application is designed for mobile phones. The first test is done in a laboratory. The second test is done in the street. The aim of this paper is to present both tests and to compare them. The main result is that both tests present advantages and drawbacks and that they complement each other. The in-laboratory test allows more precise analysis. The in-street test gives the possibility to observe behaviours induced by a richer context.

Services Web Adaptés aux utilisateurs nomades BIBAKFull-Text 133-136
  Céline Lopez-Velasco; Marlène Villanova-Oliver; Jérôme Gensel; Hervé Martin
Web services, emergent technologies based on standard architecture and standard languages, allow interoperability between different actors (provider and requestor of services). However today, no Web service standard takes really into account the adaptation concept. This is a crucial issue since the users do not only expect Web services to fulfil their needs but also to be adapted to their profiles (personal characteristics and environmental ones) and, especially in the case of nomadic users, to be adapted to both their location and the limited capabilities of their devices. We propose an extension, called AWSDL, of the standard of Web services description language (WSDL) in order to support the Web services adaptation. A module has been developed in order to evaluate how the AWSDL descriptions of Web services and user requests match.
Keywords: mobility, user adaptability, web services

Systémes multi-agent

Un intergiciel par envoi de message économe en énergie basé sur une approche multi-agents: support pour la communication sans fil dans les systèmes complexes physiques ouverts BIBAKFull-Text 137-143
  J.-P. Jamont; M. Occello
Open physical complex artificial systems involve wireless autonomous entities submitted to strength constrained energetic policies. The features of these systems naturally lead to apply multiagent techniques to ensure both the autonomy of entities and the best organization of the whole system. We propose a multiagent approach for wireless communication management and functional integrity maintaining for such physical multiagent systems using self-organization mechanisms. We show the performances of this multiagent approach by comparison to usual communication management based on wireless protocols used in this area. The genericity of our contribution is highlighted by the proposition of a middleware layer integrated in agent. We give an insight to a real world application of instrumentation of an underground instrumentation using the middleware.

Négociation entre agents au sein de réseaux ad-hoc BIBAKFull-Text 145-151
  Cosmin Carabelea; Michael Berger
In the last years the multi-agent paradigm has emerged as a suitable solution to the challenges of electronic commerce (e-commerce) applications. However, new problems arise in mobile-commerce scenarios, where agents negotiating on behalf of their users are deployed on mobile devices. Negotiation is a time-constraint process and it might be difficult to realize applications in ad-hoc networks. In this paper we investigate the means to deploy agents negotiating on handheld devices in ad-hoc networks. We implemented a test application called ADvertising on MObile Phones (ADOMO) where an agent executed on a handheld device negotiates and establishes contracts with commercial agents in its neighborhood. The objects of the negotiations and contracts are commercial advertisements (ads) to be displayed on the device's screen in exchange for a small fee / benefit. First, we describe an implementation of this application and obtained results. In the second part we show modifications to the system in order to enable the creation of contracts in a shorter time. The agents were deployed on both a PocketPC and a smart phone.
Keywords: ad-hoc networks, agents, bluetooth, negotiation

Mondes augmentés

Modèle d'interaction mixte: la réalité mixte à la lumière des modalités d'interaction BIBAKFull-Text 153-160
  Céline Coutrix; Laurence Nigay; Philippe Renevier
Mixed Reality seeks to smoothly link the physical and data processing (digital) environments. In recent years, mixed reality has been the subject of growing interest. Although mixed reality systems are becoming more prevalent, we still do not have a clear understanding of this interaction paradigm. This article introduces a new interaction model called Mixed Interaction model. It adopts a unifying point of view on mixed reality by considering the interaction modalities that are involved for defining mixed environments. This article presents the model after explaining its foundations, applies it to describe and compare existing systems and shows its generative power for designing new forms of mixed interaction.
Keywords: interaction modality, interaction model, mixed reality, multimodality

Le projet RAMPE: système interactif d'information auditive pour la mobilité des personnes aveugles dans les transports publics BIBAKFull-Text 169-176
  G. Baudoin; O. Venard; G. Uzan; A. Paumier; J. Cesbron
In this paper, we present the RAMPE project whose objective is to design, realize and experiment a system for the assistance and information of blind people so that they can increase their mobility and autonomy in public transport. It is intended to equip bus or tramway stops or to be installed in poles of transport interactions. It is based on smart hand-held devices that are WiFi enabled Personal Digital Assistant (PDA) able to communicate by a wireless WiFi connection with fixed equipment in bus or tram stations. The smart hand-held devices can present and filter vocal messages, they can adapt themselves to the type of information system available at the stations, they can react to real-time information sent by the stations. A special care has been given to the design of the man machine interface and to the management of priorities in the real-time vocal information application.

2M: un espace de conception pour i'interaction bi-manuelle BIBAKFull-Text 177-184
  Gilles Bailly; Laurence Nigay; David Auber
In the physical world, most human activities involve the use of two hands. As part of ubiquitous computing that aims at combining the physical and the digital worlds, understanding how to design two-handed interaction is therefore important. This article presents a new design space for two-handed interaction, called 2M. The 2M design space takes its foundations in two complementary research domains: multimodal interaction and two-handed interaction. On the one hand we enrich the multimodal design space to take into account the roles of the two hands. On the other hand, we extend the two-handed interaction design space to cover the temporal as well as fusion aspects of multimodal interaction. This article presents the resulting 2M design space and demonstrates its descriptive power. We finally study the generative capacity of 2M for designing new forms of two-handed interaction in the context of the NavGraphe project that focuses on the interactive manipulation of very large biological structures (e.g., RNA structures).
Keywords: bimanual, design space, multimodality, two-handed interaction

Composition et couplage

Composition flexible de services d'objets communicants BIBAKFull-Text 185-192
  Mathieu Vallée; Fano Ramparany; Laurent Vercouter
Les environnements d'informatique pervasive mettent en oeuvre de nombreux objets communicants. L'ensemble de ces objets forme un système d'informatique ubiquiste dont une interface intuitive et flexible doit être l'environnement même d'un utilisateur. Chacun de ces objets offrant des services spécifiques nombreux et variés, leur contrôle et leur suivi par les utilisateurs devient problématique et induit une surcharge cognitive. Dans cet article, nous présentons une approche qui vise à composer automatiquement des services fournis par des objets communicants de façon à proposer aux utilisateurs des services de haut niveau. La prise en compte d'informations de contexte pour adapter le processus de composition est une des caractéristiques essentielles de ce système, et constitue une étape indispensable à la construction intelligente de services de haut niveau, et donc à une véritable intelligence ambiante.
   Pervasive computing environments involve a variety of smart devices and home appliances. Communities of these devices form a ubiquitous information processing system to which the physical environment should provide an intuitive and flexible user interface. Since each of these devices offers specific services, their number and variety make it difficult for users to control and monitor them all and tend to overload humans cognitive load. In this paper, we present an approach aimed at automatically composing device services, so that users can benefit from higher level services. We also ensure that context information such as users' locations and preferences is properly taken into account within the composition process. We believe that building mechanisms for synthesizing context-aware high level services is a mandatory step towards Ambient Intelligence.

Techniques de couplage de bureaux: Ambient-Desktop comme illustration BIBAKFull-Text 193-200
  Nicolas Barralon; Viet-Tung Nguyen; Gaëtan Rey
Coupling interaction resources is key to ubiquitous computing by permitting users to construct their own interactive spaces. In this article, we examine the requirements related to coupling and we propose a set of middleware techniques (I-AM and the Contextors infrastructure) to support coupling between the interaction resources of conventional workstations. We illustrate the application of these techniques with Ambient-Desktop, a desktop that complies to the look and feel of current graphical desktops extended with novel HCI features for addressing coupling.

Détection automatique des groupes d'interactions BIBAKFull-Text 201-204
  Maisonnasse Jérôme; Brdiczka Oliver
This work brings a new perception to intelligent environments for human activity recognition. To understand human activities, we need to differentiate users concerned and their interpersonal links. We propose a new group interaction detection tool based on an assumption that conversational turn taking is synchronized inside groups. We assess HMM-based and algorithmic approaches to build a detector which is able to segment interaction groups from speech detection. Both approaches show good results thus confirm the conversational hypothesis.
Keywords: conversationnal analysis, groups of interaction clustering, intelligent environment, markov model, speech detection, ubiquitous computing

Tutorial « informatique mobile et pervasive » BIBAFull-Text 209
  Michel Adiba; Patricia Serrano Alvarado; Laurence Nigay; Michel Riveill
L'Informatique Mobile définit un vaste domaine d'études pluridisciplinaires. Elle s'inscrit dans le mouvement de l'informatique pervasive, ubiquitaire et évanescente. La multiplication des ordinateurs de poche et des assistants personnels, la généralisation de l'utilisation des cartes à puces et la multiplication des systèmes embarqués dans des objets d'usage courant (automobile, télévision, etc.) sont des témoins de cet essor. L'explosion de la téléphonie mobile constitue un autre exemple significatif de la formidable extension de ce domaine.
