   With the rapid advancement of Autonomous Vehicle (AV) technology, improving user trust is critical to realizing its full potential. This study introduces a Virtual Character (VC) as an assistant for passengers, designed to enhance trust in AVs. The VC acts as an interactive guide, providing feedback and emotional cues to capture passengers’ attention during uncertain situations. To assess its impact on trust, Situation Awareness (SA), and acceptability, we integrated the VC into a Virtual Reality-simulated AV environment. Thirty-six participants experienced four conditions: a static VC, an emotion-only VC, an action-only VC, and a combined action–emotion VC. Results show that incorporating a VC can enhance user trust, SA, and acceptance of AV technologies. VC actions have a stronger effect on trust than emotional expressions, while emotional cues alone have the potential to reduce stress. Notably, participants preferred a VC that combines both action and emotion. These findings highlight the value of integrating expressive and behavior-rich VCs into AV interfaces to communicate system awareness, reduce uncertainty, and strengthen passenger trust.

   For autonomous vehicles (AVs) to be widely accepted, users must not only feel safe but also understand how the vehicle perceives and responds to its environment. Augmented Reality (AR) enables real-time, intuitive communication of such information, helping foster trust and enhance situation awareness (SA). This paper presents the results of three online user studies that investigate the design of different AR visualization strategies in simulated AV environments. Although the studies used prerecorded videos, they were designed to simulate ecologically realistic driving scenarios. Study 1 evaluates six types of highlight visualizations (bounding box, spotlight, point arrow, zoom, semantic segmentation, and baseline) across five driving scenarios varying in complexity and visibility. The results show that highlight effectiveness is scenario-dependent, with bounding boxes and spotlights being more effective in occluded or ambiguous conditions. Study 2 explores predictive visualizations, comparing single vs. multiple predicted paths and goals to communicate future trajectories. Findings indicate that single-path predictions are most effective for enhancing trust and safety, while multi-goal visualizations are perceived as less clear and less helpful. Study 3 examines the impact of spatial anchoring in AR by comparing screen-fixed and world-fixed presentations of timeto-contact information. Results demonstrate that world-fixed visualizations significantly improve trust, perceived safety, and object detectability compared to screen-fixed displays. Together, these studies provide key insights into when, what, and how AR visualizations should be presented in AVs to effectively support passenger understanding. The findings inform the design of adaptive AR interfaces that tailor visual feedback based on scenario complexity, uncertainty, and environmental context.

   Visual body modification in Augmented Reality (AR) offers new opportunities to study perception and embodiment. However, achieving real-time, egocentric body transformation remains technically challenging due to the need for accurate tracking, segmentation, and rendering. We present a modular AR platform designed for real-time visual hand replacement using video see-through displays. The system integrates six independent modules—video extraction, hand tracking, avatar animation, segmentation, hand erasing, and rendering—communicating via shared memory for low-latency processing. Each module supports multiple implementations, allowing adaptability to different experimental goals. Our open-source platform enables controlled manipulation of hand appearance, supporting perceptual and behavioral studies involving body image and interaction.

   Integrating Autonomous Vehicles (AVs) into daily life requires a fundamental shift in user trust and acceptance. Previous studies show that Augmented Reality (AR) visualization can improve trust in AVs. However, those studies primarily focus on adding information related to the driving task. The question then must be asked: What happens if we remove unnecessary information or modify information unrelated to the driving task? Our work presents six AR visualizations within AVs, including adding, modifying, and removing information related to or non-related to the driving task. We evaluate the influence of these visualizations on trust, technology acceptance, and Situational Awareness (SA) in AVs by conducting a study employing a custom-developed driving simulator. Results show that using AR to add, modify, or remove information can significantly increase trust in AVs.

   As Virtual Reality (VR) applications continue to develop further, many questions persist regarding how to optimize user performance in virtual environments. Among the numerous variables that could influence performance, the mass of the props used within VR applications is particularly noteworthy. This paper thus proposes a user study to investigate the influence of the mass of a prop (a tool replica) on users’ performance in a pointing task. A VR within-subject experiment was conducted, with three different weighted replicas, to collect objective and subjective data from participants. Results suggest that the mass of the prop can influence task performance in terms of error-free selection time, number of errors, and subjective perceptions such as perceived difficulty and cognitive load. Indeed, performance was significantly better when using a lighter replica than a heavier one, and subjective user-experience-related metrics were also significantly improved with a light replica. These results help pave the way for additional research on user performance within virtual environments.

   Literature provides few if no data on the current use and exposure of individuals to virtual reality (VR) and/or augmented reality (AR) technologies in the wild. Most of the publications concern prototypes and systems tested in laboratories, whereas actual uses in private and professional situations are poorly documented. Obtaining a clear picture of the current use and exposure to VR/A/M technologies is thus difficult, beyond high-profile applications (e.g. Pokemon GO) and devices (e.g. Oculus rift). To address this gap, a survey was conducted in the context of a working group at the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) among a sample of 776 French people aged 18 and over who have already experienced virtual or augmented reality (from a representative national sample of 2970 French people aged 18 and over) and 122 children aged 6 to 17 who have already experienced virtual or augmented reality. The online questionnaire was designed to identify the people concerned and the situations of exposure to these technologies, the type of systems and devices used, as well as to examine the possible occurrence of cyber-sickness symptoms felt after or during exposure. Beyond the lack of previous studies, a specific difficulty and limit to interpreting previous surveys lies in the emerging nature of the technologies under consideration, i.e. the fact that they are evolving technologies, still little known and/or poorly understood (especially for the general population) and responding to uses and needs that are still incompletely identified. Thus, the study’s instructions relied on a precise definition of VR/AR combined with typical illustrations of the different types of devices and uses presented in the questionnaire. The results show that 26% of French people aged 18 and over have already experienced virtual or augmented reality, whereas 33% of French people with children between the ages of 6 and 17 report that their children have already experienced VR/AR. Characteristics of the users population, situations and duration of use, as well as devices mostly used are clarified. In terms of health consequences, between one-third and one-half of users report having experienced symptoms during or following expo- sure to VR or AR, depending on how the measurement is conducted. The most common self-reported symptoms are dizziness and headache. Symptoms mainly appear during or immediately after exposure and disappear very quickly afterwards, with the exception of headaches and visual fatigue, which seem to persist more over time. The types of use and technologies used seem to be determining factors in the occurrence of symptoms. The conclusion set perspectives to recommendations.

3. Métavers: au-delà des «casques de réalité virtuelle»

   Depuis l’annonce de Mark Zuckerberg sur le « métavers » en novembre 2021, la tendance s’est retournée et la généralisation de la réalité virtuelle auprès du grand public n’a pas encore eu lieu. C’est donc l’occasion de faire un point d’étape sur les grands défis qui restent à résoudre en vue d’une adoption plus massive. Tout d’abord, qu’entendait-il par « métavers » ? Il s’agissait de la combinaison d’une réalité virtuelle (un monde virtuel appelé Horizon Worlds), des moyens d’accès à ce monde virtuel, de possibilités d’interactions avec d’autres humains et quelques éléments autour de la monétisation. Par réalité virtuelle, on entend ici le fait de s’immerger, par exemple avec un casque comme le Meta Quest, dans un environnement artificiel pouvant représenter en partie la réalité et d’interagir en temps réel avec ce monde virtuel (Arnaldi et al., 2018). On peut par exemple interagir avec des représentations d’êtres humains qu’on appelle alors des avatars, correspondant à des personnes réelles ou potentiellement mus par l’intelligence artificielle. La réalité mixte est une forme de généralisation de la réalité virtuelle où l’utilisateur perçoit simultanément des éléments du monde réel et des éléments de synthèse. Les technologies permettant d’accéder à cette réalité virtuelle font l’objet d’un autre article dans ce numéro, nous nous concentrerons sur les autres aspects. Parmi ceux-ci, il y a bien sûr des considérations logicielles liées aux nécessaires compromis matériels, à la représentation des mondes virtuels et en particulier des avatars mais aussi aux capacités du système sensori-moteur et cognitif humain…

   Abs PDF

   Virtual Reality (VR) has emerged as a promising solution to address the pressing concern of transferring know-how in the manufacturing industry. Making an immersive training experience often involves designing an instrumented replica of a tool whose use is to be learned through virtual training. The process of making a replica can alter its mass, making it different from that of the original tool. As far as we know, the influence of this difference on learning outcomes has never been evaluated. To investigate this subject, an immersive training experience was designed with pre and post-training phases under real conditions, dedicated to learning the use of a rotary tool. 80 participants took part in this study, split into three groups: a control group performing the virtual training using a replica with the same mass as the original tool (m = 100%), a second group that used a replica with a lighter mass than the original tool (m = 50%), and a third group using a replica heavier than the original tool (m = 150%). Despite variations in the mass of the replica used for training, this study revealed that the learning outcomes remained comparable across all groups, while also demonstrating significant enhancements in certain performance measures, including task completion time. Overall, these findings provide useful insights regarding the design of tool replicas for immersive training.

1. The Sense of Embodiment in Virtual Reality and its Assessment Methods

   Abs DOI

   The sense of embodiment refers to the sensations with being inside, having and controlling a body. In virtual reality, it is possible to substitute a person’s body with a virtual one, referred to as an avatar. Modulations of the sense of embodiment through modifications of this avatar have perceptual and behavioural consequences on users that can influence the way users interact with the virtual environment. Therefore, it is essential to define metrics that enable a reliable assessment of the sense of embodiment in virtual reality to better understand its dimensions, the way they interact, and the influence that they have on the quality of interaction in the virtual environment. In this review, we first introduce the current knowledge on the sense of embodiment, its dimensions (senses of agency, body ownership, and self-location), and how they relate the ones with the others. Then, we dive into the different methods currently used to assess the sense of embodiment, ranging from questionnaires to neurophysiological measures. We provide a critical analysis of the existing metrics, discussing their advantages and drawbacks in the context of virtual reality. Notably, we argue that real-time measures of embodiment, that are also specific and do not require double-tasking are the most relevant in the context of virtual reality. Electroencephalography seems a good candidate for the future if its drawbacks (such as its sensitivity to movement and practicality) are improved. While the perfect metric has yet to be identified if it exists, this work provides clues on which metric to choose depending on the context, which should hopefully contribute to better assessing and understanding the sense of embodiment in virtual reality.

   Text entry in Virtual Reality (VR) is becoming an increasingly important task as the availability of hardware increases and the range of VR applications widens. This is especially true for VR industrial applications where users need to input data frequently. Large-scale industrial adoption of VR is still hampered by the productivity gap between entering data via a physical keyboard and VR data entry methods. Data entry needs to be efficient, easy-to-use and to learn and not frustrating. In this paper, we present a new data entry method based on handwriting recognition (HWR). Users can input text by simply writing on a virtual surface. We conduct a user study to determine the best writing conditions when it comes to surface orientation and sensory feedback. This feedback consists of visual, haptic, and auditory cues. We find that using a slanted board with sensory feedback is best to maximize writing speeds and minimize physical demand. We also evaluate the performance of our method in terms of text entry speed, error rate, usability and workload. The results show that handwriting in VR has high entry speed, usability with little training compared to other controller-based virtual text entry techniques. The system could be further improved by reducing high error rates through the use of more efficient handwriting recognition tools. In fact, the total error rate is 9.28% in the best condition. After 40 phrases of training, participants reach an average of 14.5 WPM, while a group with high VR familiarity reach 16.16 WPM after the same training. The highest observed textual data entry speed is 21.11 WPM.

   Weathering phenomena are ubiquitous in urban environments, where it is easy to observe severely degraded old buildings as a result of water penetration. Despite being an important part of any realistic city, this kind of phenomenon has received little attention from the Computer Graphics community compared to stains resulting from biological or flow effects on the building exteriors. In this paper, we present physically-inspired deep weathering effects, where the penetration of humidity (i.e., water particles) and its interaction with a building’s internal structural elements result in large, visible degradation effects. Our implementation is based on a particle-based propagation model for humidity propagation, coupled with a spring-based interaction simulation that allows chemical interactions, like the formation of rust, to deform and destroy a building’s inner structure. To illustrate our methodology, we show a collection of deep degradation effects applied to urban models involving the creation of rust or of ice within walls.

   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.

   Introduction. Cognitive disorders can limit participation of people with neurological diseases in daily life activities, and more specifically when navigating in their outdoor environment. Augmented Reality (AR) tools seem promising for compensating these difficulties. Aim. Our main objective was to detail and discuss the existing application fields of AR devices for people with neurological disorders. Methods. We conducted our literature review between August and September 2021 using 2 databases: Medline and Scopus, with the following keywords: “augmented reality” AND: “neurological” (and synonyms: “neurology”, “neurologic”), “disorientation”, “mild cognitive”, “aid”, “cognition”. Results. We selected and analysed 13 studies. The selected articles show a good acceptance of AR devices by the participants. Research focused on navigation tasks showed that most of the participants were able to complete the navigation task without any other assistance. The notion of cognitive load which influences the user’s safety during the navigation task when using augmented reality, was often taken into account. Conclusion. We defined a framework for the use of AR that can be applied in rehabilitation and to consider its future use in the person’s environment as a technological aid for spatial navigation. Further studies on the cognitive load in people with neurological pathology are necessary to compare the results obtained to ones on healthy participants.

   Wind can influence people’s behavior and their way of inhabiting an architectural or urban space. Furthermore, virtual reality (VR) enables the simulation of different physical and sensitive phenomena such as the wind. We aim to analyze the effects of different wind representations in terms of perception of its properties and sense of presence in VR. We carry out two within-subject studies aiming at evaluating different wind representation suggestions (including audiovisual and tactile stimuli) to identify their effects on wind properties’ perception and sense of presence in the VR scene. Our analysis showed significant effects of tactile restitution over the visual effects used in the study, both for understanding wind properties and for increasing the sense of presence in the VR scene. The tactile condition (T) reduced the estimation error of wind direction by 27% compared to the visual condition (V). The wind force error was reduced by 9.8% using (T) with (V). (T) increased the sense of presence by 12.2% compared to (V). Our second experiment showed an overestimation of the wind force perceived compared to the reference value of the Beaufort scale. For the maximum force value evaluated, the average result was 91% higher than the reference value, while for the lower, the average answer was 77% higher than the reference value. Previous studies have evaluated wind rendering in virtual reality, and others have studied the visualization of wind simulation results. To our knowledge, our study is the first to compare the perception of these two types of representations as well as the effects of wind on elements of the context. We also compared the wind perception to a reference-based method, the Beaufort scale.

   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.

   Technological developments provide solutions to alleviate the tremendous impact on the health and autonomy due to the impact of dementia on navigation abilities. We systematically reviewed the literature on devices tested to provide assistance to people with dementia during indoor, outdoor and virtual navigation (PROSPERO ID number: 215585). Medline and Scopus databases were searched from inception. Our aim was to summarize the results from the literature to guide future developments. Twenty-three articles were included in our study. Three types of information were extracted from these studies. First, the types of navigation advice the devices provided were assessed through: (i) the sensorial modality of presentation, e.g., visual and tactile stimuli, (ii) the navigation content, e.g., landmarks, and (iii) the timing of presentation, e.g., systematically at intersections. Second, we analyzed the technology that the devices were based on, e.g., smartphone. Third, the experimental methodology used to assess the devices and the navigation outcome was evaluated. We report and discuss the results from the literature based on these three main characteristics. Finally, based on these considerations, recommendations are drawn, challenges are identified and potential solutions are suggested. Augmented reality-based devices, intelligent tutoring systems and social support should particularly further be explored.

2. Direct and Indirect vSLAM Fusion for Augmented Reality

   Journal of Imaging, 2021

   Abs DOI

   Augmented reality (AR) is an emerging technology that is applied in many fields. One of the limitations that still prevents AR to be even more widely used relates to the accessibility of devices. Indeed, the devices currently used are usually high end, expensive glasses or mobile devices. vSLAM (visual simultaneous localization and mapping) algorithms circumvent this problem by requiring relatively cheap cameras for AR. vSLAM algorithms can be classified as direct or indirect methods based on the type of data used. Each class of algorithms works optimally on a type of scene (e.g., textured or untextured) but unfortunately with little overlap. In this work, a method is proposed to fuse a direct and an indirect methods in order to have a higher robustness and to offer the possibility for AR to move seamlessly between different types of scenes. Our method is tested on three datasets against state-of-the-art direct (LSD-SLAM), semi-direct (LCSD) and indirect (ORBSLAM2) algorithms in two different scenarios: a trajectory planning and an AR scenario where a virtual object is displayed on top of the video feed; furthermore, a similar method (LCSD SLAM) is also compared to our proposal. Results show that our fusion algorithm is generally as efficient as the best algorithm both in terms of trajectory (mean errors with respect to ground truth trajectory measurements) as well as in terms of quality of the augmentation (robustness and stability). In short, we can propose a fusion algorithm that, in our tests, takes the best of both the direct and indirect methods.

3. Detection of Removed Objects in 3D Meshes Using Up-to-Date Images for Mixed-Reality Applications

   Abs DOI

   Precise knowledge of the real environment is a prerequisite for the integration of the real and virtual worlds in mixed-reality applications. However, real-time updating of a real environment model is a costly and difficult process; therefore, hybrid approaches have been developed: An updated world model can be inferred from an offline acquisition of the 3D world, which is then updated online using live image sequences under the condition of developing fast and robust change detection algorithms. Current algorithms are biased toward object insertion and often fail in object removal detection; in an environment where there is uniformity in the background—in color and intensity—the disappearances of foreground objects between the 3D scan of a scene and the capture of several new pictures of said scene are difficult to detect. The novelty of our approach is that we circumvent this issue by focusing on areas of least change in parts of the scene that should be occluded by the foreground. Through experimentation on realistic datasets, we show that this approach results in better detection and localization of removed objects. This technique can be paired with an insertion detection algorithm to provide a complete change detection framework.

   The application of virtual reality in human activities has been rapidly growing during the last decade. Shopping for food is an important part of people’s daily lives. As overnight delivery services of fresh produce, such as Amazon Fresh, are in their development stage, more studies on virtual stores for perishable products are needed because the quality of FaVs cannot be easily assessed by consumers when virtual stores are used. This research examines the impact of a physical store, a non-immersive virtual store, and an immersive virtual store environment on consumers’ perceptions and purchase behavior toward fruits and vegetables (FaVs). Experimental between-subjects design (i.e., three groups), combined with a questionnaire survey (after-only design), is used to address the study objectives. The research found that consumers’ perceptions of FaVs in both non-immersive and immersive virtual stores (VS) are similar to those in a physical store. By contrast, consumers buy more FaVs in both non-immersive and immersive VS compared to a physical store. The findings also indicate that consumers tend to rely more on extrinsic cues (i.e., FaVs’ prices) in the immersive VS when evaluating the FaVs on offer and less on intrinsic cues (e.g., FaVs’ appearance) they use in the physical store. The results have important implications for practitioners and researchers with regard to the usefulness of virtual reality for better understanding of consumer behavior.

   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.

   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.

    We present a method which can quickly and robustly match 2D and 3D point patterns based on their sole spatial distribution, but it can also handle other cues if available. This method can be easily adapted to many transformations such as similarity transformations in 2D/3D, and affine and perspective transformations in 2D. It is based on local geometric consensus among several local matchings and a refinement scheme. We provide two implementations of this general scheme, one for the 2D homography case (which can be used for marker or image tracking) and one for the 3D similarity case. We demonstrate the robustness and speed performance of our proposal on both synthetic and real images and show that our method can be used to augment any (textured/textureless) planar objects but also 3D objects.

    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.

   In this paper we propose a methodology describing a global process used to model both urban spatiotempporal data and applications. During the design phase, we use a tool based on the Entity-Relation formalism that is dedicated to spatiotemporal data design (MADS). The resulting conceptual schemas are adapted to the particularities of the urban data by distingusihing between physical concepts (continuants) and events (occurents). This distinction enables a better readability of conceptual schemas and a more powerful interoperability. The resulting schemas are then implemented in an object oriented environment. In the end, we use a GIS to query and graphically represent urban data. In order to test the capacity of our proposed modeling methodology in a real case, we apply it on a case study whose objective is to analyze pedestrian walkways in urban areas

   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.

5. GDMS: An abstraction layer to enhance Spatial Data Infrastructures usability

   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.

   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.

    The urban environment is deÞned as the interaction between the cityÕs morphological characteristics and its physical behaviour based on human interpretation. Contemporary psychology emphasizes the relation between perception and action and conÞrms that perception can be enhanced by the receptorÕs motion. Basing this study on these principles, it is assumed that virtual reality techniques bring both immersion and interaction to static computer generated images and they can be used to study sunlight effects as well as daylight ambience. This paper shows the methodology of Ôsunlight effectsÕ analysis of both real and virtual worlds and builds a framework for a comparison.

   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.

   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.
