Evaluation of an Information Assistance System Based on an Agent-based Architecture in Transportation Domain: First Results

The evaluation of interactive systems is a wide and rich research domain: many methods, criteria and tools are available. In this article, we are focused on agent-based interactive systems. We first describe the agent oriented architecture used in our researches. Then we propose an evaluation approach based on three complementary techniques: assistance evaluation tool, questionnaire, and verbalization. The validation of our approach occurred within the framework of a project involving an industrial partner which is running the current urban transport network (tramway and bus) in the town of Valenciennes, France. The main results of the evaluation of an agent-based Information Assistance System (IAS) are presented. This evaluation is based on two scenarios: normal or distrupted running mode. This evaluation has been conducted in laboratory

Contribution à l'évaluation des systèmes interactifs orientés agents

This thesis presents a contribution to the evaluation of interactive systems based on oriented agent architecture. The appearance of new agent based architectures and systems provide new problems concerning the evaluation of agent based interactive systems. So, our work aims at the proposal of a principle that couples agent-based architecture of interactive systems and their evaluation. Based on this principle, we propose an evaluation aid system based on an electronic informer which allows us to acquire and analyse human-machine interactions in agent-based interactive environments. This electronic informer is used in the framework of the SART (Système d'Aide à la Régulation de Trafic) project in order to evaluate an Information System. This system was validated by a first evaluation in laboratory. The perspectives of this work aim mainly the improvement of the evaluation aid system and the evaluation of the Information System in a real work case.Ce mémoire présente une contribution à l'évaluation des systèmes interactifs basés sur des architectures orientées agents. Avec l'apparition de nouvelles architectures et de nouveaux systèmes à base d'agents, de nouvelles problématiques d'évaluation des systèmes interactifs orientés agents apparaissent. Notre contribution consiste à proposer un principe de couplage entre une architecture à base d'agents du système interactif et son évaluation. En se basant sur ce principe, un système d'aide à l'évaluation basé sur un mouchard électronique baptisé MESIA (Mouchard électronique pour l'Evaluation des Systèmes interactifs Orientés Agent) a été proposé. Nous avons utilisé ce mouchard, dans le cadre du projet SART (Système d'Aide à la Régulation de Trafic), pour évaluer un Système d'Aide à l'Information des voyageurs (SAI). Une première évaluation a permis de valider globalement la maquette proposée. Les perspectives de recherche, visant en particulier à améliorer le système d'aide à l'évaluation proposé et à effectuer une évaluation dans un cadre réel de fonctionnement du SAI, terminent ce mémoire de cette thèse

Modelling of an interactive system with an agent-based architecture using Petri nets, application of the method to the supervision of a transport system.

International audienceThis article presents an original method using high level Petri nets for the specification and design of interactive systems. We suggest an agent oriented architecture based on the classic components of an interactive application (application, dialogue control, interface with the application). Our approach is validated via the specification and design of a human–machine interface used in the supervision of a land-based transport system (bus/tramway)

Graphical Controls Based Environment for User Interface Evaluation

Part 3: Short PapersInternational audienceFor more than two decades, the HCI community has elaborated numerous tools for user interface evaluation. Although the related tools are wide, the evaluation remains a difficult task. This paper presents a new approach for user interface evaluation. The proposed evaluation process focuses on utility and usability as software quality factors. It is based on the UI ergonomic quality inspection as well as the analysis and the study of the Human-Computer interaction. The proposed approach is mainly based on graphic controls dedicated to the user interface evaluation. These controls have, on the one hand, the role to compose graphically the interfaces. On the other hand, they contribute to the UI evaluation through integrated mechanisms. The evaluation is structured into two phases. The first consists of a local self-evaluation of the graphical controls according to a set of ergonomic guidelines. This set is specified by the evaluator. The second allows an electronic informer to estimate the interaction between the user interface (graphically composed by the evaluation based controls) and the user

EvalCHOICE: A Decision Support Approach for the Usability Evaluation of Interactive Adaptive Systems

International audienceSuccessful usability evaluation of interactive adaptive systems requires the use of appropriate methods. Different usability evaluation methods exist in the literature. These methods can be applied in association with the individual layers and with the whole adaptive system. In each situation, it is essential to apply the appropriate evaluation methods. In this paper, we propose a novel decision support approach called EvalCHOICE. It guides evaluators in the choice of appropriate usability evaluation methods for individual layers and the adaptive system as a whole. Our proposal is applied to determine the suitable evaluation methods for a given Web-based adaptive system in the field of transport

Deux approches d’évaluation précoce de systèmes interactifs: application à la supervision du transport urbain

International audienceL’évaluation précoce de systèmes interactifs fait actuellement l’objet de nombreuses recherches. Certaines visent à coupler explicitement conception et évaluation par différents mécanismes logiciels. Nous décrivons dans cet article deux approches d’évaluation précoce tirant profit de nouvelles technologies et paradigmes. La première propose un couplage explicite entre architecture à base d’agents et agents d’évaluation ; la seconde exploite la programmation par aspects. Des illustrations dans le domaine du transport sont fournies pour les deux approches

Structural Defect Impact on Changing Optical Response and Raising Unpredicted Ferromagnetic Behaviour in (111) Preferentially Oriented Nanocrystalline NiO Films

NiO thin films deposed on a glass substrate, “NiO/glass”, are successfully prepared using a spray pyrolysis technique (SPT) at 460 °C and characterized via X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray, Atomic force microscopy (AFM), spectroscopic ellipsometry (SE), Photoluminescence (PL) and diverse electric and magnetic studies. The structural investigation shows that the synthesized films crystallized in a cubic structure with (111) preferential orientation. The NiO layers exhibit a uniform grain of regular sizes with aggregates randomly distributed across their surface. The optical properties of the NiO thin films evidenced a normal optical dispersion as well as good transparency of the NiO films. An unpredicted ferromagnetic aspect was raised due to the high oxygen presence in the synthetized material. A high thermal dependency of the conductivity, as well as a semiconductor behavior of the grown NiO material, is also demonstrated
