Abstract: International audience; Along with the development of the scripting technology in cartography, such as the Generic Mapping Tools (GMT) and libraries of R programming language, geologic and geophysical mapping is being vigorously promoted, where the integration of the thematic data, such as GEBCO/SRTM, EGM-2008 and open geological raster and vector layers is one of the primary datasets that provides the highresolution raw sources for cartographic visualization in the geologically complex regions like Pakistan. This study aims to integrate scripting methods of automated cartography, methods of applied geoinformatics for geomorphometric analysis and technical data processing (formatting, projecting, plotting), to provide a synthesis of the geological, geophysical and geomorphological maps of Pakistan they as new information supporting analysis of the geospatial variations of geology, geomorphology, tectonics and gravity fields with a special focus on the geologically remarkable region of Pakistan: Sulaiman Fold Belt and Muslim Bagh ophiolite complex. This study presents new 12 thematic maps, which are technically made using scripting approaches and open tools. All maps cover the region of Pakistan and they are made using open source tools: GMT, R and QGIS. A GMT and R based scripting mapping is applied for mapping Pakistan, and its algorithm steps are presented stepwise as code snippets. A system complex approach of the data integration and formats reshaping, data conversion and reformatting for a single project of the geology of Pakistan is designed and developed based on the combination of the programming and scripting techniques and with additional QGIS based mapping, which effectively integrates the thematic geospatial multi-origin datasets. Various color palettes and cartographic visualization approaches have been used to achieve the best visualization. The resulting maps are explained and discussed. Correlation between spatial phenomena of Earth's gravity, geologic evolution and tectonic movements were pointed out and commented on. New 12 maps present the regional geologic setting of the country.

Abstract: International audience; This paper presents using GDAL utilities and GRASS GIS for topographic analysis of the raster grids based on GEBCO DEM as NetCDF file at 15 arc-second intervals. The focus study area encompasses the area around Okinawa Trough, Ryukyu trench-arc system, southern Japan, East China Sea and the Philippine Sea, west Pacific Ocean. Several GDAL utilities were applied for data processing: gdaldem, gdalwarp, gdalinfo, gdal_translate. The data were imported to GRASS GIS via r.in.gdal. Data visualization highlighted high resolution and accuracy of GEBCO grid, enabling topographic modelling at the advanced level. The algorithm of DEM processing, implemented in GDAL utility gdaldem, was used for generating multipurpose topographic models: aspect, hillshade, roughness and topographic indices, such as Topographic Position Index (TPI), Terrain Ruggedness Index (TRI). Thematic maps (topography, geoid, marine free-air gravity) were visualized using GRASS GIS modules for raster (d.rast, r.colors, r.contour) and vector (d.vect, v.in.region, d.legend) data processing. The results demonstrated smoother bathymetry in the East China Sea and rugged relief in the Philippine Sea which corresponds to their different geological and geophysical settings. The presented methodology of the topographic analysis based on DEM demonstrated technical aspects of GDAL and GRASS as scripting approach of advanced cartography.

Abstract: International audience; The South Sandwich Trench located eastward of the Drake Passage in the Scotia Sea between Antarctica and South America is one of the least studied deep-sea trenches. Its geomorphological formation and present shape formed under the strong influence of the tectonic plate movements and various aspects of the geological setting, i.e., sediment thickness, faults, fracture zones and geologic lineaments. The aim of this paper is to link the geological and geophysical setting of the Scotia Sea with individual geomorphological features of the South Sandwich Trench in the context of the phenomena of its formation and evolution. Linking several datasets (GEBCO, ETOPO1, EGM96, GlobSed and marine freeair gravity raster grids, geological vector layers) highlights correlations between various factors affecting deep-sea trench formation and development, using the Generic Mapping Tools (GMT) for cartographic mapping. The paper contributes to the regional studies of the submarine geomorphology in the Antarctic region with a technical application of the GMT cartographic scripting toolset.

Abstract: International audience; GRASS GIS Modules for Topographic and Geophysical Analysis of the ETOPO1 DEM and Raster Data: North Fiji Basin, Pacific Ocean The paper presents topographic analysis based on the raster data (NetCDF and grid formats) and visualization of the geophysical datasets that resembles the topographic surface. Geographically, the research focuses on the region of North Fiji Basin, South Pacific Ocean. North Fiji Basin is one of the marginal basins located at the converging boundary between the Pacific and Australian tectonic plates and is notable for complex geological settings. Methodology is based on GRASS GIS and includes scripting and cartographic visualization. Data include ETOPO1, GEBCO, EGM96 gravity and geoid raster grids imported to GRASS GIS via GDAL library ('r.in.gdal' module) from NetCDF and GRD formats, evaluated and visualized. Several GRASS modules were used as a sequential scripting for displaying and modelling data. Geomorphometric analysis (slopes, curvature, aspect, elevation) was performed by module 'r.slope.aspect' based on ETOPO1 grid. Statistical data analysis (histograms, polar diagram) for topographic and geoid gravitational fields were visualized by combination of GRASS modules d.rast, g.region, d.polar, d.histogram, d.grid, d.legend, d.text. Topographic analysis reveal that free-air gravity anomaly mark the continental shelf-slope border showing that generally, geophysical settings are dominated by the topographic effect. These observations are consistent with the inferred prominent role of the geophysical settings. The histograms reveal that topography (trenches, abyssal plains, shelf areas) has values between-5,000 and-1,000 m, and a clear peak with major values between 100 and 350 m above sea level. This distribution indicates that dominating depths of the ocean floor in North Fiji Basin are between-1,500 to-3,000 m. The aspect map of the ETOPO1 initial raw raster grid show that the surface has mostly 50°-110° oriented slope followed by data range in 250°-300° oriented slopes which is well correlating with submarine topography and general relief forms. The steepening of the gravity values between 50 and 55 mGal and 58 to 63 mGal indicates geoid undulations suggesting that bathymetry is controlled by the geological settings in the study area. Consolebased scripts of GRASS GIS are presented together with cartographic outputs showing its effectiveness for the geographic spatial analysis.

Abstract: The study investigated geomorphology of the Japan Trench located east of Japan, Pacific Ocean. A high-resolution GEBCO Gridded Bathymetric Dataset was used for modeling, mapping and visualization. The study aimed to compare and analyse variations in the geomorphic structures of the two parts of the trench and to visualize variations in the geological, geophysical and bathymetric settings. Technically, the cartographic work was performed using scripting based on the Generic Mapping Toolset (GMT). Modelled cross-sectioning orthogonal profiles transecting the trench in a perpendicular direction were automatically digitized and graphed in the two segments. The results of the bathymetric analysis shown that the southern part is shallower: with deeper values in absolute (139 samples between –7000 to –8000 m) and statistical records (the most frequent values are within –5500 to –5800 m) comparing to the northern segment (–5300 to –5500 m). The geomorphological analysis shows a more complicated relief in the northern part of the trench, which has a higher seismic activity. The southern part has a gentler slope on the Honshu island side. The geoid modeling along the trench ranges in 0–20 mGal. The highest values are recorded by the Honshu Island (>40 mGal). The rest of the area has rather moderate undulations (20–40 mGal). The free-air marine gravity of the Sea of Japan is

Abstract: International audience; To make constrained manipulation of 3D objects in desktop 3D applications, 3D transformation widgets are commonly used. However, their performance degrades on touchscreens because of low accuracy of touch inputs and the fingertip occlusion problem. In this paper, we present TouchSketch, a touch-based interface which allows users to perform independently fine-grained object translation, rotation and scaling on mobile devices. Our manipulation technique permits using the non-dominant hand to specify the manipulation reference while the dominant hand is used to determine the operation mode and control the transformation. In addition to 3D manipulation, TouchSketch provides also a set of functions to edit the shape of 3D objects. Users can use this application to accomplish rapid sketching tasks. We have conducted a user study to evaluate the efficiency of our manipulation technique. The results show that our technique outperforms a Widget-based technique regarding both the efficiency and fluency.

Abstract: International audience; This paper proposes an experimental protocol that aims to evaluate in a strictly comparable context tactile and tangible modalities for a virtual environment exploration on tablet. We propose four modalities: tactile interaction with sticks, classic tactile interaction, tangible interaction with a 1:2.5 scale factor and tangible interaction with a 1:5 scale factor. We hypothesize that the tangible interactions will provide users a better spatial representation of the virtual environment, with however, a difference depending on the scale factor. Moreover we interest on the subjective evaluation (usability and acceptability) of these modalities.; Le présent article propose un protocole expérimental visant a évaluer, dans un contexte strictement comparable, les modalités d'interaction tactile et tangible pour l'exploration d'environnement virtuel sur tablette. Nous proposons quatre modalités : l'interaction tactile avec des sticks, l'interaction tactile classique, l'interaction tangible à l'échelle 1 :2,5 et l'interaction tangible à une échelle de 5. Nous faisons l'hypothèse que la modalité tangible permettra aux utilisateurs de se construire une meilleure représentation spatiale de l'environnement virtuel, avec toutefois des différences selon l'échelle utilisée. En outre, on s'intéresse a l'évaluation subjective (utilisabilité, acceptation) de ces différentes modalités d'interaction.

Abstract: International audience; Nous faisons la démonstration d'une nouvelle technique de navigation au doigt dans une interface tactile de type smartphone sous Android OS. Cette technique repose sur (1) une arborescence logique de navigation sous la forme d'un menu linéaire hiérarchique, (2) une logique séquentielle de navigation basée sur la manipulation d'un focus de sélection, (3) des gestes de "glissé" permettant une manipulation continue sans levé de doigt. Contrairement aux interfaces tactiles standards dont l'interaction est basée sur le pointage, la technique MenuDfA permet l'utilisation du positionnement relatif seul ou combiné avec le positionnement absolu. Cette approche ouvre de nouvelles perspectives dans le domaine de la conception universelle des interfaces.

Abstract: National audience; Interaction with computers using freehand gestures becomes more and more popular. However, it is hard to make precise inputs by making gestures in air without a physical support. As a result, selecting a small object from dense target clusters is still a difficult task for bare hand interaction. In this paper, we present the HorizontalDragger, a new selection technique aimed to improve the selection precision by converting the 2D selection problem into a 1D selection problem. After setting a region of interest in the display, all the objects inside the region are considered as potential targets. The user can drag the index finger horizontally to choose the desired target. Because the effective width of each potential target is set to a constant value, the user can switch the focus in the region of interest in a predictable way. We have made two preliminary studies to find appropriate values for the size of the region of interest and the effective width. We are going to evaluate the performance of this technique by comparing it with other recent remote selection techniques in the future work.

Abstract: International audience; We introduce a compact hierarchical procedural model that combines feature-based primitives to describe complex terrains with varying level of detail. Our model is inspired by skeletal implicit surfaces and defines the terrain elevation function by using a construction tree. Leaves represent terrain features and they are generic parameter-ized skeletal primitives such as mountains, ridges, valleys, rivers, lakes, or roads. Inner nodes combine the leaves and subtrees by carving, blending, or warping operators. The elevation of the terrain at a given point is evaluated by traversing the tree and by combining the contributions of the primitives. The definition of the tree leaves and operators guarantees that the resulting elevation function is Lipschitz which speeds up the sphere tracing used to render the terrain. Our model is compact and allows for the creation of large terrains with a high level of detail using a reduced set of primitives. We show the creation of different kinds of landscapes and demonstrate that our model allows to efficiently control the shape and distribution of landform features.

Abstract: International audience; In this paper, we introduce a new 7-Handle manipulation technique for 3D objects in immersive virtual environ-ments and its evaluation. The 7-Handle technique includes a set of seven points which are flexibly attached to an object. There are three different control modes for these points including configuration, manipulation and locking / unlocking modes. We have conducted an experiment to compare the efficiency of this technique with the tradi-tional 6-DOF direct manipulation technique in terms of time, discomfort metrics and subjective estimation for precise manipulations in an immersive virtual environment in two consecutive phases: an approach phase and a refinement phase. The statistical results showed that the completion time in the approach phase of the 7-Handle technique was significantly longer than the completion time of the 6-DOF technique. Nevertheless, we found a significant interaction effect between the two factors (the manipulation technique and the object size) on the com-pletion time of the refinement phase. In addition, even though we did not find any significant differences between the two techniques in terms of intuitiveness, ease of use and global preference in the result of subjective data, we obtained a significantly better satisfaction feedback from the subjects for the efficiency and fatigue criteria.

Abstract: International audience; This paper aims to raise the question : "How much 3D bimanual interaction techniques can be useful to the design of collaborative interaction techniques in the field of Collaborative Virtual Environment (CVE)?". Indeed, CVE involve the use of complex interaction techniques based on specific collaborative metaphors. The design of these metaphors may be a difficult task because it has to deal with collaborative issues that came from sparse research areas (Human-Computer Interfaces, Human-Human Interactions, Networking, Physiology and Social Psychology). Metaphors for bimanual interactions have been developed for a while essentially because it is a widely spread area of interest for common tasks. Bimanual interactions involve the simultaneous use of both hands of the user in order to achieve a goal with better performances compared to uni-manual interactions thanks to a natural skill that is proprioception. This collaborative aspect could certainly be a helpful entry point in the design of efficient collaborative interaction techniques extended from improved bimanual metaphors. However, the proprioceptive sense cannot be considered in the same way, and additional features must be proposed to be able to collaborate efficiently. Thus, awareness is a key to let CVE be usable and the availability of collaborative feedbacks is essential to extend bimanual interactions toward collaborative ones. In this paper, we based our study on existing work on bimanual and collaborative interaction techniques trying to draw similarities between them. We emphasize common points between both fields that could be useful to better design both metaphors and awareness in CVE.

Abstract: International audience; In the domain of Collaborative Virtual Environments (CVEs), many virtual worlds, frameworks and techniques are built based on a specific and direct purpose. There is not a general and still good and efficient enough solution for all the collaborative systems. Depending on the purpose of the collaborative work, the techniques of interaction and of manipulation change from one application to another. Despite this difference between interaction techniques, they always benefit greatly from awareness features that help in explicating implicit knowledge related to one's own and others' working activities as well as to virtual workspace. In addition, people in CVEs also use communication channels to negotiate shared understandings of task goals, of task decomposition and of task progress. Therefore, awareness and communication are usually considered as "instruments" to complete collaborative tasks in the environment. However, few research work have been devoted to improving the awareness and the communication channels in CVEs for a better collaboration between users. In this paper, we will study the importance of awareness and communication in collaborative virtual environments. We will investigate different kinds of awareness which need to be carefully designed. We will also discuss different communication means and how to cope with this diversity, so we can benefit from the availability of different peripheral devices and can find an effective communication means to work together. Finally, we will make some propositions to overcome these actual limitations of CVEs.

Abstract: International audience; Exploration of large-scale 3D Virtual Environments (VEs) is often difficult because of lack of familiarity with complex virtual worlds, lack of spatial information that can be offered to users and lack of sensory (visual, auditory, locomotive) details compared to the exploration of real environments. To address this problem we propose three guiding techniques in the form of navigation aids to enable one or several users (called helping user(s)) to help one main user (called exploring user) to explore the VE efficiently. These three techniques consist in drawing directional arrows, lighting up a path to follow, and orienting a compass to show a direction to the exploring user. All the three techniques are generic so they can be used for any kind of 3D VE, and they do not affect the main structure of the VE so its integrity is guaranteed.

Abstract: International audience; In the context of scientific data analysis, we propose to compare a remote collaborative manipulation technique with a single user manipulation technique. The manipulation task consists in positioning a clipping plane in order to perform cross-sections of scientific data which show several points of interest located inside this data. For the remote collaborative manipulation, we have chosen to use the 3-hand manipulation technique proposed by Aguerreche et al. which is very suitable with a remote manipulation of a plane. We ran two experiments to compare the two manipulation techniques with some participants located in two different countries. These experiments showed that the remote collaborative manipulation technique was significantly more efficient than the single user manipulation when the three points of interest were far from each other inside the scientific data and, consequently, when the manipulation task was harder and required more precision. When the three points of interest were close from each other, there was not significant difference between the two manipulation techniques.

Abstract: Generating content for third person games and machinima requires knowledge in cinematography (camera placement, framing, lighting) and editing (cutting between cameras). In existing systems, such knowledge either comes from the final user (machinima) or from a database of precompiled solutions (third person games). In this paper, we present a system that can make decisions about editing and automatically generate a grammatically correct movie during game interaction. While previous work described techniques for choosing camera setups and generating virtual footage, most of them do not propose general computational frameworks to express variations in directorial styles. We introduce a framework for generating a well-edited movie from such footage, based on film grammar. Our system computes a sequence of shots by simultaneously choosing which camera to use, when to cut in and out of the shot, and which camera to cut to. We cast film editing as a cost minimization problem in the space of possible shot sequences and provide an efficient search algorithm for computing the edit with minimal latency. In contrast to previous work, our method precisely examines all possible edit points and relies on a well-founded model to account for shot duration., La création de contenus pour le jeu vidéo et le machinima necessite des connaissances en cinématographie et montage. Nous présentons un système capable de calculer automatiquement le cadrage et le montage des caméras virtuelles de facon a produire un film d'animation au cours du jeu, sans intervention des joueurs. Pour cela, nous formalisons le montage cinématographique comme un problème de minimisation d'énergie et proposons des solutions interactives pour calculer un film de moindre coû, tout en controlant le rythme de montage.

Abstract: International audience; The selection and manipulation of 3D content in desktop virtual environments is commonly achieved with 2D mouse cursor-based interaction. However, by interacting with image-based techniques we introduce a conflict between the 2D space in which the 2D cursor lays and the 3D content. For example, the 2D mouse cursor does not provide any information about the depth of the selected objects. In this situation, the user has to rely on the depth cues provided by the virtual environment, such as perspective deformation, shading and shadows. In this paper, we explore new metaphors to improve the depth perception when interacting with 3D content. Our approach focus on the usage of 3D cursors controlled with 2D input devices (the Hand Avatar and the Torch) and a pseudo-motion parallax effect. The additional depth cues provided by the visual feedback of the 3D cursors and the motion parallax are expected to increase the users' depth perception of the environment. The evaluation of proposed techniques showed that users' depth perception was significantly increased. Users were able to better judge the depth ordering of virtual environment. Although 3D cursors showed a decrease of selection performance, it is compensated by the increased depth perception.

Abstract: International audience; We propose PAC-C3D as a new software model for 3D Collaborative Virtual Environments (CVE). This model merges the results from two research fields: distribution models for CVE and HCI design for computer-supported cooperative work. PAC-C3D proposes to describe each part of a shared virtual object through explicit interfaces to ensure a strong separation between the core functions of a virtual environment, its (visual) representations, and its collaborative features such as synchronization and consistency maintenance between remote users. PAC-C3D makes it possible to design a CVE with low dependency between the core functions, the distribution mode and the 3D graphics API used. It explicitly deals with the main distribution modes encountered in CVE. It makes it easy to use different 3D graphics API for different nodes involved in the same collaborative session, providing interoperability between these 3D graphics API. It also makes it possible to integrate other kinds of 3D representations such as physics engines into the CVE.

Abstract: International audience; Motivated by the importance of having real-time feedback in sketch-based modeling tools, we present a framework for terrain edition capable of generating and displaying complex and high-resolution terrains. Our system is efficient and fast enough to allow the user to see the terrain morphing at the same time the drawing editing occurs. We have two types of editing interactions: the user can draw strokes creating elevations and crevices; and previous strokes can be interactively moved to different regions of the terrain. One interesting feature of our tool is that terrain primitives can be interactively manipulated similarly to primitives in vector-graphics tools. We achieve real- time performance in both modeling and rendering using a hybrid CPU-GPU coupled solution. We maintain a coarse version of the terrain geometry in the CPU by using a quadtree, while a fine version is produced in the GPU using tessellation shaders.

Abstract: International audience; In this paper we analyze and compare the trajectories made in a Virtual Environment with two different navigation techniques. The first is a standard joystick technique and the second is the Walking-In-Place (WIP) technique. We propose a spatial and temporal analysis of the trajectories produced with both techniques during a virtual slalom task. We found that trajectories and users' behaviors are very different accross the two conditions. Our results notably show that with the WIP technique the users turned more often and navigated more sequentially, i.e. waited to cross obstacles before changing their direction. However, the users were also able to modulate their speed more precisely with the WIP. These results could be used to optimize the design and future implementations of WIP techniques. Our analysis could also become the basis of a future framework to compare other navigation techniques.

Abstract: International audience; In this paper we introduce the concept of a Reconfigurable Tangible Device for manipulation of 3D objects in virtual environments by single or multiple users. This Reconfigurable Tangible Device (RTD) provides points of manipulation rigidly linked together. The shape of the RTD can be reconfigured at any time as its arms can be compressed or stretched by users at will. Due to its simple shape the Reconfigurable Tangible Device can be attached to any 3D virtual object. Then, it can fully define the motion of the virtual object in 6 Degrees of Freedom. Two examples of Reconfigurable Tangible Device were developed: one with three points of manipulation (a reconfigurable triangle) and one with four points. We illustrate how these two simple devices can match many different shapes of 3D objects, and in different contexts. Preliminary testing was conducted with the RTD based on three points of manipulation involving a collaborative manipulation task in virtual reality. It produced better subjective appreciation for the RTD compared to more classical 3D collaborative techniques.

Abstract: International audience; This paper compares three interactive techniques for two-user collaborative manipulation in virtual environments. The first technique averages positions and orientations provided by users (Mean technique). The second technique (DOF separation) splits degrees of freedom of the manipulated object among users. The third technique is a tangible device grasped simultaneously by the two users.We have conducted an experiment where participants were asked to manipulate and assemble, in a collaborative manner, virtual parts. Our results suggest that the mean technique leads to faster completion time probably due to smaller physicalmotions. However, the tangible device seems globally preferred by users in terms of immersion and realism of the task.

Abstract: International audience; In this paper we introduce a new 3D interaction technique called “3-Hand Manipulation”, for multi-user collaborative manipulation of 3D objects. The 3-Hand Manipulation relies on the use of three manipulation points that can be used simultaneously by three different “hands” of two or three users. Interestingly, the three translation motions of the manipulation points can fully determine the resulting 6 degrees of freedom motion of the manipulated object. We describe the implementation of the 3-Hand Manipulation, its graphical representations and an illustration of its use by two or three users on an insertion task in immersive virtual environment. This technique could be used in various applications of collaborative VR such as for virtual prototyping, training simulations, assembly and maintenance simulations.

Abstract: International audience; In this paper we present a new metaphor for interaction within Collaborative Virtual Environments (CVE). This metaphor is dedicated to non-immersive or semi-immersive 3D interactions, for which users cannot afford to buy expensive devices neither for 3D visualization of their virtual environment nor for interaction. With these low-cost restrictions, we think that it is more effective to use basic 2D metaphors rather than to try to adapt 3D virtual metaphors which would be more difficult to use because of the poor immersion level offered by such systems. The problem that will arise within a CVE is that it is difficult to make a user aware of the 2D metaphors used by another user, because they are not associated with a 3D virtual object of the shared universe. So our idea is to provide to a user a 3D virtual ray (using ray-casting for object selection) that would act like a 2D pointer on the screen, allowing the user to only control the 2D position of the closest ray end, and calculating the orientation of the ray so that its projection on the screen would always be a point. This way, since the user is controlling a 3D virtual ray, the other users can be made aware of his activity. To test the efficiency of this 2D Pointer / 3D Ray, we have made some experiments making users compare different devices to realize some simple selection and manipulation tasks. The results show that this kind of 2D solution is efficient and allows 3D interaction within Virtual Environments by people who cannot afford expensive immersive hardware. This new metaphor allows more users to collaborate within CVE.

Abstract: International audience; We present a novel method called motion-pointing for selecting a set of visual items such as push-buttons without actually pointing to them. Instead, each potential target displays a rhythmically animated point we call the driver. To select a specific item, the user only has to imitate the motion of its driver using the input device. Once the motion has been recognized by the system, the user can confirm the selection to trigger the action. We consider cyclic motions on an elliptic trajectory with a specific period, and study the most effective methods for real-time matching such a trajectory, as well as the range of parameters a human can reliably reproduce. We then show how to implement motion-pointing in real applications using an interaction technique we call move-and-stroke. Finally, we measure the throughput and error rate of move-and-stroke in a controlled experiment. We show that the selection time is linearly proportional to the number of input bits conveyed up to 6 bits, confirming that motion-pointing is a practical input method.

Abstract: International audience; Building virtual reality applications is still a difficult and time consuming task. Software developers need a common set of 3D widgets, hardware device abstraction and a set of software components that are easy to write and use. These means are intended to provide collaborative interactions in rich virtual applications, easy use of many input devices, and easy deployment on multi-sites for shared environments. We propose in this paper a new formalism for 3D interactions in virtual environments to define what an interactive object and an interaction tool are, and how these two kinds of virtual objects can communicate together. As a consequence, we describe a communication protocol between interaction tools and interactive objects. We then obtain users on different sites that are able to interact in a shared environment with interactive objects that are provided with access levels. Moreover, this protocol introduces interoperability between VR platforms. Finally we explain how we implement this protocol with aggregations of reusable small software components to ease development of VR applications.

Abstract: National audience; Virtual reality has lead to development of many methods for interacting between real humans and virtual objects in 3D spaces. Nowadays, some new developments are made for cooperative interactions which means that several persons can act simultaneouly on shared objects. A cooperation requires new metaphors to make several persons acting on same objects possible and also to have some new feedbacks to users to explain shared actions. Finally, some new technical issues in platforms appear like synchronization and consistency between sites

Abstract: International audience; This demonstration introduces new ways for exploring Collaborative Virtual Environments (CVE) that contain 3D scientific data sets obtained by simulation. In order to make decisions accordingly to their collective knowledge and understanding of the simulation, the users must collaborate and share experiences and comments. We provide tools to enable a good coordination between the users, and to make each user aware of the activity of others. Each user can navigate within the CVE: change her own position, orientation and scale. Each user can also add annotations within the virtual universe. We propose several 3D layouts for the presentation of the data, associated with different 3D navigation tools. Consequently, the user can explore the data accoording to various parameters such as time or temperature. Last we propose a new 3D interaction tool, called 2D Cursor / 3D Pointer, dedicated to selection and manipulation of 3D objects, and application control. This 2D cursor is associated with a 3D geometry in order to make people aware of the activity of the users who are using this tool.

Abstract: International audience; Plumage is an interface for interactive 3D audio/graphic scene browsing and design. The interface relies on the notion of tape heads in a sonic and graphic 3D space made of feathers associated with sound micro-samples. The spatial layout of the feathers is defined by sound parameters of the associated samples. The musical play is the outcome of a continuous and interactive navigation in the sound space controlled by direct manipulation of tape head trajectories. This work is based on the design of interactions. A simple and efficient audio graphic navigation is designed through the combination and synchronization of elementer sound object triggerings.; Plumage est une interface pour le contrôle interactif de la composition et du jeu de scènes graphiques et audio spatialisées. L'interface repose sur un environnement graphique 3D composé de têtes de lecture animées parcourant un espace sonore matérialisé par des plumes associées associées`associéesà des grains sonores (des micro-´ échantillons). La disposition spatiale des plumes repose sur des paramètres sonores deséchantillons qu'elles représentent. Plumage porte sur le design d'interaction. Il rend tangibles, organise et syn-chronise des lectures d'´échantillons avec leurs comportements graphiques et sonores pour une navigation audio-graphique efficace.

Abstract: International audience; Real time collaborative interactions within CVEs rely on the low latency offered by high speed networks. When low level network troubles occur during a collaborative session, participants of networked collaborative virtual environments can suffer from misunderstanding weird behavior of some objects of the virtual universe. We want to make such a virtual world easier to understand by using some graphic visualizations in such a way that the users become aware of these problems. It is a kind of augmentation of the Virtual Environment thanks to dedicated 3D metaphors associated to some objects of the virtual environment. We also want to allow users to work while these troubles occur, maybe with only restricted interaction possibilities, by making some interactive objects migrate onto the same site than the user who wants to interact with them. This is why we present then how two independent mechanisms may be coupled together for a better management and awareness of network troubles while interacting within a networked collaborative virtual environment: an awareness system that visualizes, through special metaphors, the existence of a network trouble as strong delay or disconnection; and a virtual object migration system that allows the migration of an object from one site to another to ensure a non interrupted manipulation in case of network troubles.

Abstract: International audience; This paper describes a novel 3D interaction technique called the “SkeweR”, dedicated to the 2-user collaborative manipulation of objects in virtual environments. This technique enables two users to move simultaneously the same virtual object in 3D. For this aim, each user manipulates the object by one crushing point, like handling the extremity of a skewer. The SkeweR uses only translation information from the users' motions to change both the position and orientation of the manipulated object. By using more crushing points, this technique could easily be extended to 3 or more users. Thus, the SkeweR technique could be used to improve the collaborative manipulation of objects in numerous applications of Virtual Reality, such as: virtual prototyping, maintenance and training simulations, architectural mock-up reviews, etc.

Abstract: International audience; Gasp (General Animation and Simulation Platform) was at rst designed to distribute the animation and simulation of multi-agent virtual environments. In the Gasp framework, a virtual world is composed of any number of simulation objects. These simulation objects can be autonomous agents, interactors or user representations. We dene interactors as simulation objects which provide information on user input readable by any simulation object. Because simulation ob- jects can read information from any number of other simula- tion objects, it is then quite easy to design objects on which any number of users (or other simulation objects) can collaborate. As the Gasp run-time kernel can distribute the calculations associated with those simulation objects on dif- ferent workstations, collaborative virtual environments can easily be built. In this paper, we explain how, in our framework, interactors and interactive objects are distributed for collaborative interactions and how it is possible to build an interactive object from an existing object without changing the code of that object.

Abstract: International audience; Although spherical displays become more and more pervasive, the design of interactive content for these displays still remains difficult as it requires most developers to get familiar with specific tools for managing the output and input. In this paper, we present a framework for developing applications for multitouch spherical displays that makes it possible to create interactive content by programming standard GUI applications, as for example interactive web pages. The principal idea is to adapt the window output and interaction input of classical GUIs outside the application. To this end, our framework consists of two standalone applications where the first one captures the window output and changes the projection via GPU shaders, and the second one adapts the input with a Node.js server and sends interaction and mouse events. In this way, the same application runs on a standard desktop, and on the spherical display. Advantages of our approach include fast prototyping, and the fact that masses of developers can create applications for spherical displays just as if it were, for example, classical web applications. We believe that our framework will contribute to making spherical displays even more pervasive in the future.

Abstract: International audience; This demonstration introduces a new 3D interaction technique called "3-Hand Manipulation", for multi-user collaborative manipulation of 3D objects. This technique relies on the use of three manipulation points that can be used simultaneously by three different "hands" of two or three users. The three translation motions of the manipulation points fully determine the resulting 6 DOF motion of an object. We describe the graphical representations of the 3-Hand Manipulation and an illustration of its use by two or three users on an insertion task.
