Digitalization and Virtual Assistive Systems in Tourist Mobility: Evolution, an Experience (with Observed Mistakes), Appropriate Orientations and Recommendations

Digitalization and virtualization are extremely active and important approaches in a large scope of activities (marketing, selling, enterprise management, logistics). Tourism management is also highly concerned by this evolution. In this paper we try to present today's situation based on a 7-week trip showing appropriate and shame situations. After this case study, we give a list of appropriate practices and orientations and confirm the fundamental role of User Experience in validating the proposed assistive system and the User Interfaces needed for client/user satisfaction. We also outline the expected role of Metaverse in the future of the evolution of this domain.

Contextual Mobile Learning Strongly Related to Industrial Activities: Principles and Case Study

M-learning (mobile learning) can take various forms. We are interested in contextualized M-learning, i.e. the training related to the situation physically or logically localized. Contextualization and pervasivity are important aspects of our approach. We propose in particular MOCOCO principles (Mobility - COntextualisation - COoperation) using IMERA platform (Mobile Interaction in the Augmented Real Environment). We are studying various mobile learning contexts related to professional activities, in order to master appliances (Installation, Use, Breakdown diagnostic and Repairing). Contextualization, traceability and checking of execution of prescribed operations are based mainly on the use of RFID labels. Investigation of the appropriate training methods for this kind of learning situation, applying mainly a constructivist approach known as "Just-in-time learning", "learning by doing", "learning and doing", constitutes an important topic of this project. From an organizational point of view we are in perfect symbiosis with EPSS - Electronic Performance Support System [12] and our objective is to integrate learning in professional activities in three ways: 1/ before work i.e. to learn about coming actions, 2/ after work i.e. to learn about past actions to understand what happened and accumulate experience, 3/ during work i.e. to master the problem just-in-time

Ordinateur porté support de réalité augmentée pour des activités de maintenance et de dépannage

In this paper we present a case study of use of wearable computer within the framework of activities of maintenance and repairing. Besides the study of configuration of this wearable computer and its peripherals, we show the integration of context, in-situ storage, traceability and regulation in these activities. This case study is in the scope of a huge project called HMTD (Help Me To Do) which aim is to apply MOCOCO (Mobility, COoperation, COntextualisation) and IMERA (Mobile Interaction in the Augmented Real Environment) principles for better use, maintenance and repairing of equipments in the domestic, public and professional situations.

IRVO: an Interaction Model for designing Collaborative Mixed Reality systems

This paper presents an interaction model adapted to mixed reality environments known as IRVO (Interacting with Real and Virtual Objects). IRVO aims at modeling the interaction between one or more users and the Mixed Reality system by representing explicitly the objects and tools involved and their relationship. IRVO covers the design phase of the life cycle and models the intended use of the system. In a first part, we present a brief review of related HCI models. The second part is devoted to the IRVO model, its notation and some examples. In the third part, we present how IRVO is used for designing applications and in particular we show how this model can be integrated in a Model-Based Approach (CoCSys) which is currently designed at our lab.
