International audience; This paper presents an ongoing work aimed at evaluating Extended Reality training for the interaction of general public with mobile robots, with a particular focus on semi-autonomous cars.

International audience; It can be difficult to find your way in public transport, especially when the journey combines indoor and outdoor trans-portation. We designed an innovative vibrotactile device dedicated to guide a pedestrian in public transport. This multi-modal interface can be used to guide a pedestrian in unknown public transport. The device can be used by visually impaired person. The device has been tested during two main phases. The first step was to test the device using virtual reality while the second step test was to test the device in a real environment. This paper presents the first part of the evaluation of the device. We have developed a virtual reality scenario to assess the objective and subjective utility of the device. The results showed that the device could properly guide users. We also evaluated the usefulness of a warning vibration preceding a message. It was found that the vibration seems to introduce confusion to the pattern recognition by the user.

National audience; Robots are becoming more and more present in our everyday life: they are already used for domestic tasks, for companionship activities, and soon they will be used to assist humans and collaborate with them in their work. Human-robot collaboration has already been studied in the industry, for ergonomics and efficiency purposes, but more from a safety than from an acceptability point of view. In this work, we focused on how people perceive robots in a collaboration task and we proposed to use virtual reality as a simulation environment to test different parameters, by making users collaborate with virtual robots. A simple use case was implemented to compare different robot appearances and different robot movements. Questionnaires and physiological measures were used to assess the acceptability level of each condition with a user study. The results showed that the perception of robot movements depended on robot appearance and that a more anthropomorphic robot, both in its appearance and movements, was not necessarily better acceptedby the users in a collaboration task. Finally, this preliminary use case was also the opportunity to guarantee the relevance of using such a methodology -- based on virtual reality, questionnaires and physiological measures -- for future studies.

International audience; In this paper, we introduce a new deformation method adapted to immersive design. The use of Virtual Reality (VR) in the design process implies a physical displacement of project actors and data between the virtual reality facilities and the design office. The decisions taken in the immersive environment are manually reflected on the Computed Aided Design (CAD) system. This increases the design time and breaks the continuity of data workflow. On this basis, there is a clear demand among the industry for tools adapted to immersive design. But few methods exist that encompass CAD problematic in VR. For this purpose, we propose a new method, called D3, for "Draw, Deform and Design", based on a 2 step manipulation paradigm, consisting with 1) area selection and 2) path drawing, and a final refining and fitting phase. Our method is discussed on the basis of a set of CAD deformation scenarios.
