1. What about the real use of virtual, extended and augmented reality? a survey of a French representative sample Burkhardt, Jean-Marie, Attia, Dina, Behar-Cohen, Francine, Grynszpan, Ouriel, Klinger, Evelyne, Lobjois, Régis, Moreau, Guillaume, Nannipieri, Olivier, Paljic, Alexis, Piolino, Pascale, Hung, Thai-Van, Tisseron, Serge, and Viaud-Delmon, Isabelle In 15th International Conference on Applied Human Factors and Ergonomics (AHFE 2024) 2024
2. Manipulating the Sense of Embodiment in Virtual Reality: a study of the interactions between the senses of agency, self-location and ownership Guy, Martin, Jeunet-Kelway, Camille, Normand, Jean-Marie, and Moreau, Guillaume In ICAT-EGVE2022, the joint international conference of the 32nd International Conference on Artificial Reality and Telexistence & the 27th Eurographics Symposium on Virtual Environments 2022 [Abs] [pdf]

   In Virtual Reality (VR), the Sense of Embodiment (SoE) corresponds to the feeling of controlling and owning a virtual body, usually referred to as an avatar. The SoE is generally divided into three components: the Sense of Agency (SoA) which characterises the level of control of the user over the avatar, the Sense of Self-Location (SoSL) which is the feeling to be located in the avatar and the Sense of Body-Ownership (SoBO) that represents the attribution of the virtual body to the user. While previous studies showed that the SoE can be manipulated by disturbing either the SoA, the SoBO or the SoSL, the relationships and interactions between these three components still remain unclear. In this paper, we aim at extending the understanding of the SoE and the interactions between its components by 1) experimentally manipulating them in VR via a biased visual feedback, and 2) understanding if each sub-component can be selectively altered or not. To do so, we designed a within-subject experiment where 47 right-handed participants had to perform movements of their right-hand under different experimental conditions impacting the sub-components of embodiment: the SoA was modified by impacting the control of the avatar with visual biased feedback, the SoBO was altered by modifying the realism of the virtual right hand (anthropomorphic cartoon hand or non-anthropomorphic stick “fingers”) and the SoSL was controlled via the user’s point of view (first or third person). After each trial, participants rated their level of agency, ownership and self-location on a 7-item Likert scale. Results’ analysis revealed that the three components could not be selectively altered in this experiment. Nevertheless, these preliminary results pave the way to further studies.

3. Virtual Data Sphere: Inverse Stereographic Projection for Immersive Multi-Perspective Geovisualization Spur, Maxim, Tourre, Vincent, Moreau, Guillaume, and Le Callet, Patrick In ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences 2022 [Abs] [pdf]

   Immersive geospatial visualization finds increasing application for navigation, exploration, and analysis. Many such require the display of data at different scales, often in views with three-dimensional geometry. Multi-view solutions, such as focus+context, overview+detail, and distorted projections can show different scales at the same time, and help place an area of interest within its surroundings. By inverting the principle of stereographic projection – projecting spatial features from a map onto a virtual sphere which surrounds the viewer – we present a novel technique for immersive geospatial focus+context that aims to mitigate problems with existing solutions. This sphere can intersect the map, dividing it into two parts: the inside of the sphere, which stays unchanged, and the outside, which gets projected to the surface, resulting in an inversion of the lens metaphor by distorting the context instead of the focus. This detail-in-context visualization maximizes the amount of context that can be legibly shown by the smooth compression inherent to the stereographic projection, and by utilizing otherwise unused screen space in the sky. The projection method allows for easy control over the projection and distortion characteristics by varying only two main parameters – the sphere’s radius and its position. The omnidirectional nature of our system makes it particularly well-suited for immersive displays by accommodating typical immersive exploration and fully utilizing the additional visual space available. Applying our system to an urban environment, we were able to solicit positive reactions during feedback sessions with experts from urbanism.

6. MapStack: Exploring Multilayered Geospatial Data in Virtual Reality Spur, Maxim, Tourre, Vincent, David, Erwan, Moreau, Guillaume, and Le Callet, Patrick In Proc. 11th International Conference on Information Visualization Theory and Applications 2020 [Abs] [pdf]

   Virtual reality (VR) headsets offer a large and immersive workspace for displaying visualizations with stereoscopic vision, compared to traditional environments with monitors or printouts. The controllers for these devices further allow direct three-dimensional interaction with the virtual environment. In this paper, we make use of these advantages to implement a novel multiple and coordinated view (MCV) in the form of a vertical stack, showing tilted layers of geospatial data to facilitate an understanding of multi-layered maps. A formal study based on a use-case from urbanism that requires cross-referencing four layers of geospatial urban data augments our arguments for it by comparing it to more conventional systems similarly implemented in VR: a simpler grid of layers, and switching (blitting) layers on one map. Performance and oculometric analyses showed an advantage of the two spatial-multiplexing methods (the grid or the stack) over the temporal multiplexing in blitting. Overall, users tended to prefer the stack, be ambivalent to the grid, and show dislike for the blitting map. Perhaps more interestingly, we were also able to associate preferences in systems with user characteristics and behavior.

   Virtual objects look farther on the sides: the anisotropy of distance perception in virtual reality Peillard, Etienne, Thébaud, Thomas, Normand, Jean-Marie, Argelaguet, Ferran, Moreau, Guillaume, and Lécuyer, Anatole In IEEE Virtual Reality 2019 [Abs] [doi] [pdf]

   The topic of distance perception has been widely investigated in Virtual Reality (VR). However, the vast majority of previous work mainly focused on distance perception of objects placed in front of the observer. Then, what happens when the observer looks on the side? In this paper, we study differences in distance estimation when comparing objects placed in front of the observer with objects placed on his side. Through a series of four experiments (n=85), we assessed participants’ distance estimation and ruled out potential biases. In particular, we considered the placement of visual stimuli in the field of view, users’ exploration behavior as well as the presence of depth cues. For all experiments a two-alternative forced choice (2AFC) standardized psychophysical protocol was employed, in which the main task was to determine the stimuli that seemed to be the farthest one. In summary, our results showed that the orientation of virtual stimuli with respect to the user introduces a distance perception bias: objects placed on the sides are systematically perceived farther away than objects in front. In addition, we could observe that this bias increases along with the angle, and appears to be independent of both the position of the object in the field of view as well as the quality of the virtual scene. This work sheds a new light on one of the specificities of VR environments regarding the wider subject of visual space theory. Our study paves the way for future experiments evaluating the anisotropy of distance perception in real and virtual environments.

43. A General Strategy for Semantic Levels of Details in 3D Urban Visualization Zhang, Fan, Tourre, Vincent, and Moreau, Guillaume In Eurographics Workshop On Urban Data Modelling And Visualisation 2013 [Abs] [doi]

    Applications based on urban environments are applied frequently in daily life which increases the needs for a high quality visualization result. It combines the urban environment and the special application-related topic together. The urban environment can be visualized with different scales, namely with different levels of detail to improve rendering and processing performance of the application. Visualization for the special topic, semantics, similarly is in need of a smart strategy to stay consistent with information density. This paper proposes a general strategy to handle semantic levels of detail visualization in urban environment. An example is given to illustrate how it is applied. Later, a mapping between urban environment levels of detail and semantic levels of detail is discussed. In the last part, the limitations of the general strategy are stated. And visualization issues for semantics are listed such as the proper visualization form and technique for a given semantic level of detail. This paper aims to bring about a wider discussion on semantic levels of detail visualization in urban environment.

    At present, more than a half of the world population is living in urban areas. Therefore urbanization control has become a major issue. Among the social, economical and ecological factors that are taken into account in decision-making, environmental issues now have a greater impact. To address these issues, researchers are faced with new problems among which are tool disparity, knowledge sharing and enhancement (both for data and methods). What data usually have in common is a geographic reference. We propose a common localized semantics for these tools as well as a workflow to allow data integration. We will also try to show to what extent our infrastructure and tools will be an asset to integrate knowledge production methods in order to combine research works altogether. We are especially seeking the integration of multi-disciplinary research works to provide urban management authorities with new indicators. Beyond the strict field set of practices, themes and disciplins, we aim to set up and deploy a common semantic and the corresponding framework. This common and shared basis will provide all researchers the ability to produce complex indicators using knowledge of several different disciplines. The Spatial Data Infrastructure is a way to define best practices and guidelines for process integration and product improvement. It provides an opportunity to avoid or eliminate all the barriers through integrated models that transcend disciplines.

90. GDMS: An abstraction layer to enhance Spatial Data Infrastructures usability Bocher, Erwan, Leduc, Thomas, Moreau, Guillaume, and Cortès, Fernando González In Agile 2008 2008 [Abs]

    The practical exploitation of SDI (Spatial Data Infrastructures) raises number of issues as far as it grows. Among them is the heterogeneity of data sources and thus the difficulty for GIS users not to depend on the data source format and of course to learn different systems. This a major flaw with respect to reuse and data sharing. The purpose of our work is to propose a new semantic layer derived from the SQL language that is independent of the underlying data source. This layer, called GDMS (Generic Data source Management System) can first be seen as an abstraction layer between data sources and the SDI tools. We will also show how this layer extends both SQL and spatial semantics and improves the exploitation of the SDI, by providing feedback both in terms of work and data reuse. A simple example mixing heterogeneous data sources will be presented.

92. Free versus constrained motion for assessing wind turbines’ impacts on landscape in virtual environments Jallouli, Jihen, Moreau, Guillaume, and Salerne, Davy In International Conference on Articificial Reality and Telexistence (poster) 2008 [Abs]

    Wind turbines (WT) are socially controversial because of their visual and acoustic impacts on landscape. The studies’ limits remain on one hand, the technical and objective point of view for subjective impacts; and on the other hand the separate study of visual and acoustic aspects when landscape is multisensory. Virtual reality (VR) is here proposed - thanks to immersion and interaction potentialities - as an immersive multisensory and dynamic approach in order to assess WT impacts. For that, a comparison between a real park and the same virtual one is needed to evaluate VR for landscape impacts’ restitution. The parks are evaluated using an immersive path-based method (perception in motion): the real walking is simulated in a first experiment by a Wiimote. As results show the limits of this device, a second experiment using a very low-cost instrumented bike has been setup.

     L’imagerie de la Ville doit être compréhensible facilement à partir d’acquisition d’images sans autre appareillage afin de fournir les éléments propre à chaque bâtiment. Pour cela, il est présenté une nouvelle méthode de détection de points de fuite complètement automatique, robuste et de complexité réduite vis à vis des algorithmes classiques. La méthode proposée tient en deux étapes : une détection de segments par un algorithme de Canny-Deriche modifié suivi d’une caractérisation de chacun des segments par leur appartenance à un cercle spécifique de l’espace original en utilisant un résultat de la géométrie projective. La bonne performance en termes de robustesse se double donc d’une réduction de complexité puisque l’ensemble du processus est réalisé en 2D sans aucune aide externe.

     The objective of this paper is to evaluate the use of virtual reality as a potential decision-making tool to cognitively evaluate urban daylighting ambiences. This paper evaluates the solar effects visual perception in a real urban path in comparison to a virtual urban path in order to extract the characteristics of these effects and use them to figure out the necessary conditions for generating a physical and sensitive phenomena simulation. The comparison is based on questionnaires and interviews with participants on their judgements on sunlight during their walk through the chosen path. Our results highlight the relation between perception and the context of the urban environment , and prove that -in spite of its limits- virtual reality is able to simulate a large part of real solar effects.

     This paper discusses the use of Virtual environments (VEs) in cognitive evaluation of daylighting ambiences. We will introduce Virtual Reality as a new tool for urban planning development. This paper evaluates the degree of solar effects representation in digital models as well as the role of immersion in environmental evaluation. We attempt to compare the real world and virtual representations through solar effects visual perception. We will describe the process of 3D modelling in three levels: static, semi-dynamic and dynamic. Pedestrians? visual perception is evaluated by studying participants? judgments of outdoor urban daylighting during their observations/walk in real and virtual urban paths. Results show that solar effects representations depend on the experimental conditions, the visualization method as well as the introduction of motion to our experiment. This directed our work towards improving the degree of immersion and interaction by using free movement in the virtual world to evaluate urban daylight.

108. Motion impact on daylighting ambiance evaluation in virtual world Tahrani, Souha, Moreau, Guillaume, and Woloszyn, Philippe In Computer in Urban Planning and Urban Management, CUPUM 2005 [Abs]

     The aim of this study is to assess the use of Virtual Reality technologies (VR) in cognitive evaluation of daylighting ambiences and more generally in a context of introducing VR as a new methodology for urban planning development. The urban environment is defined by the interaction between the city’s morphological characteristics and its physical behavior based on human interpretation. Contemporary psychology emphasizes the relation between perception and action and confirms that perception can be enhanced by the receptor?s motion. In this order, psycho-physical interaction creates a complex urban space that might be fully understood by over-layering the perceived information we gather while walking and moving. In the architectural and urban field, several studies analyze the urban space by using visual dynamic perception. These studies prove that walking can be a tool for reading and evaluating public space. But they however ignore the physical impact on that evaluation, and especially the impact of light on visual perception; whereas in the VR field, there are very few studies which compare perception in the real world versus perception in the virtual world. They mainly show the essential role of movement in obtaining a better perception. This study is a continuation of our work on evaluating urban daylighting by using VR, where we attempted to evaluate the solar effects on visual perception in a real and virtual urban path (Tahrani et al. 2005). The results of that study showed that visual perception largely depends on the user?s movement in space. Our objective in this study is to improve our methodology by using free movement in the virtual world to evaluate urban daylight. However, because of the limited size of the immersive room, we have to limit the user?s motion. We are, instead, implementing the concept of a less free movement by using the ?guided visits? navigation strategy (Azpiazu et al. 2004) which should enhance visual perception while respecting the constraints of the VR simulation. Finally, we evaluate pedestrians? visual perception by studying people?s personal classification of outdoor urban daylighting during their walk in real and virtual urban paths. Three urban study tools are used: solar effects, VR technology as well as movement.
