Description

Procédé d'affichage d'un monde virtuel dans lequel évolue l'avatar d'un utilisateur d'un service de réalité virtuelle  A method of displaying a virtual world in which the avatar of a user of a virtual reality service evolves
L'invention concerne un procédé d'affichage d'un monde virtuel dans lequel évolue l'avatar d'un utilisateur d'un service de réalité virtuelle, ainsi qu'un service de réalité virtuelle comprenant des moyens pour afficher dans un mode standard un monde virtuel dans lequel évolue ledit avatar et des moyens pour mettre en œuvre un tel procédé. Les services de réalité virtuelle tels que SecondLife® fournissent à leurs utilisateurs un monde virtuel simulé par ordinateur dans lequel lesdits utilisateurs peuvent interagir avec les éléments dudit monde virtuel par l'intermédiaire d'un terminal, par exemple un ordinateur fixe ou portable, un assistant personnel (PDA, pour Personal Digital Assistant) ou un smartphone tel que l'Iphone® d'Apple®. The invention relates to a method for displaying a virtual world in which the avatar of a user of a virtual reality service evolves, as well as a virtual reality service comprising means for displaying in a standard mode a virtual world in which evolves said avatar and means for implementing such a method. Virtual reality services such as SecondLife® provide their users with a computer-simulated virtual world in which said users can interact with the elements of said virtual world via a terminal, for example a desktop or laptop computer, an assistant Personal Digital Assistant (PDA) or a smartphone such as the Apple® Iphone®.
En particulier, les services de réalité virtuelle offrent à leurs utilisateurs de nombreuses opportunités d'expériences, notamment celle, à un certain degré, de la téléprésence. L'ouvrage « Communication in the Age of Virtual Reality » (F. BIOCCA, M.R. LEVY, Lawrence Erlbaum Associates, ISBN 0805815503, 1995) présente de façon approfondie les définitions et possibilités se rapportant aux services de réalité virtuelle. In particular, virtual reality services offer their users many opportunities for experimentation, including, to a certain degree, telepresence. The book "Communication in the Age of Virtual Reality" (F. BIOCCA, M. R. LEVY, Lawrence Erlbaum Associates, ISBN 0805815503, 1995) provides an in-depth look at definitions and possibilities for virtual reality services.
En outre, les services de réalité virtuelle trouvent une application dans des domaines de plus en plus nombreux et variés, notamment le commerce électronique, l'éducation, la formation en entreprise, la fiction, voire même la recherche. In addition, virtual reality services are finding their way into more and more diverse fields, including e-commerce, education, business training, fiction, and even research.
Avec la démocratisation d'Internet, la popularité des services de réalité virtuelle augmente de façon exponentielle. D'après l'article disponible à l'adresse http://www.businesswire.com/news/google/20070424008287/en, d'ici fin 201 1 , 80% de internautes seront des utilisateurs d'un service de réalité virtuelle. Cette grande popularité s'explique en partie par la simplicité d'accès à un service de réalité virtuelle. N'importe quel utilisateur peut s'inscrire localement à un tel service depuis un terminal en créant un avatar pour le représenter dans le monde virtuel fourni par ledit service, puis se connecter audit service en lançant un navigateur ou une application cliente installée sur ledit terminal pour afficher sur l'écran dudit terminal les zones dudit monde virtuel dans lesquelles l'avatar dudit utilisateur est localisé. With the democratization of the Internet, the popularity of virtual reality services is growing exponentially. According to the article available at http://www.businesswire.com/news/google/20070424008287/en, by the end of 201 1, 80% of Internet users will be users of a virtual reality service . This great popularity is partly explained by the simplicity of access to a virtual reality service. Any user can subscribe locally to such a service from a terminal by creating an avatar to represent it in the virtual world provided by said service, then connect to said service by launching a browser or a client application installed on said terminal to display on the screen of said terminal areas of said virtual world in which the avatar of said user is located.
Une fois inscrit et connecté à un tel service, l'utilisateur peut faire interagir son avatar avec les avatars d'autres utilisateurs dudit service et avec différents objets virtuels localisés dans les mêmes zones que ledit avatar. Les objets virtuels sont des représentations en trois dimensions d'objets de la vie courante, comme par exemple des maisons, des arbres, des surfaces ou encore des tables. En particulier, l'utilisateur peut acquérir des objets virtuels pour les utiliser, par exemple pour y faire vivre son avatar s'il s'agit de maisons, ou pour les partager avec d'autres utilisateurs. Once registered and connected to such a service, the user can have his avatar interact with the avatars of other users of said service and with different virtual objects located in the same areas as said avatar. Virtual objects are three-dimensional representations of objects of everyday life, such as houses, trees, surfaces or even tables. In particular, the user can acquire virtual objects to use them, for example to make his avatar live if it is about houses, or to share them with other users.
Pour faciliter l'immersion des utilisateurs dans leurs mondes virtuels, l'un des principaux objectifs des fournisseurs de services de réalité virtuelle est de rendre lesdits mondes aussi réalistes que possible. En particulier, les fournisseurs des services de réalité virtuelle actuels concentrent leurs efforts sur la qualité d'affichage, notamment la résolution, de leurs mondes virtuels et des éléments, notamment des objets virtuels, qu'ils contiennent. De façon usuelle, la qualité d'affichage d'un objet virtuel est conditionnée par la quantité de détails, et donc d'informations, utilisés pour modéliser ledit objet. En outre, pour un utilisateur donné, la plupart des services de réalité virtuelle actuels modélisent avec le plus de détails possible les éléments présents dans les zones où est localisé l'avatar dudit utilisateur, dans le but d'afficher de façon aussi détaillée que possible les zones dans lesquelles ledit avatar évolue et ainsi améliorer l'impression de réalisme pour l'utilisateur dudit avatar. Ce principe de modélisation et d'affichage est principalement basé sur un calcul de la distance entre la localisation actuelle de l'avatar de l'utilisateur considéré et le reste des éléments présents dans la zone du monde virtuel concernée. Cependant, l'opération de modélisation effectuée est lourde et nécessite beaucoup de ressources de calcul, et elle en requiert d'autant plus lorsque le monde virtuel à modéliser est accessible depuis un réseau. To facilitate the immersion of users in their virtual worlds, one of the main goals of virtual reality service providers is to make these worlds as realistic as possible. In particular, today's virtual reality service providers are focusing on display quality, including resolution, of their virtual worlds and elements, including virtual objects, they contain. Usually, the display quality of a virtual object is conditioned by the amount of details, and therefore information, used to model said object. In addition, for a given user, most of the current virtual reality services model in as much detail as possible the elements present in the areas where the user's avatar is located, in order to display in as much detail as possible the zones in which said avatar evolves and thus improve the impression of realism for the user of said avatar. This modeling and display principle is mainly based on a calculation of the distance between the current location of the user's avatar and the rest of the elements present in the area of the virtual world concerned. However, the modeling operation performed is cumbersome and requires a lot of computing resources, and it requires all the more when the virtual world to be modeled is accessible from a network.
De nombreux travaux ont été réalisés pour améliorer la modélisation des mondes virtuels. En particulier, de nombreux services de réalité virtuelle utilisent des techniques d'affichage par téléchargement continu (pour l'anglais streaming) pour leurs mondes virtuels. Le document « A Framework for Quality Adaptive Media Streaming » (Ch. C. KRASIC, thesis for the Doctor of Philosophy degree, OGI School of Science and Engineering at Oregon Health & Science University, 2004) explique en détail les principes d'une telle technique. Many works have been done to improve the modeling of virtual worlds. In particular, many virtual reality services use streaming display techniques for their virtual worlds. The "A Framework for Quality Adaptive Media Streaming" (Ch. C. KRASIC, thesis for the Doctor of Philosophy, OGI School of Science and Engineering at Oregon Health & Science University, 2004) explains in detail the principles of such technical.
En outre, ce principe de modélisation et d'affichage des objets virtuels ne donne pas entièrement satisfaction en matière de réalisme et d'immersion, en ce qu'il ne prend pas en compte certains principes sous jacents de la psychologie humaine, notamment ceux de la perception humaine. Moreover, this principle of modeling and displaying virtual objects is not entirely satisfactory in terms of realism and immersion, in that it does not take into account certain principles underlying human psychology, particularly those of human perception.
En effet, c'est en grande partie leur capacité à interpréter et reproduire autant que possible les sens et l'expérience sociale humains qui confère aux mondes virtuels leur réalisme et permet une meilleure immersion des utilisateurs dans lesdits mondes. Indeed, it is largely their ability to interpret and reproduce as much as possible human senses and social experience that gives virtual worlds their realism and allows a better immersion of users in said worlds.
En particulier, il est bien connu qu'un utilisateur entouré de personnes et/ou d'objets concentre davantage son attention sur les personnes qu'il connaît et/ou sur les objets qui lui sont familiers, plutôt que sur l'ensemble desdites personnes et/ou desdits objets. In particular, it is well known that a user surrounded by people and / or objects focuses more on the people he knows and / or on objects that are familiar to him, rather than on all of them. and / or said objects.
La perception humaine comprend les étapes de visualisation d'objets donnés par un utilisateur, de reconnaissance desdits objets, puis de distinction des formes desdits objets. En particulier, la perception humaine prend en compte le fait que l'utilisateur distingue parmi les objets qu'il voit ceux qui lui appartiennent et/ou ceux qui lui sont plus ou moins familiers. Par exemple, lorsqu'un utilisateur entre dans un parking, il concentre en priorité son attention sur sa voiture et/ou sur celle(s) de ses proches. Human perception includes the steps of viewing objects given by a user, recognizing said objects, and then distinguishing between forms of said objects. In particular, the human perception takes into account the fact that the user distinguishes among the objects he sees those who belong to him and / or those who are more or less familiar to him. For example, when a user enters a car park, he focuses his attention primarily on his car and / or those of his family.
Dans les mondes virtuels, les utilisateurs font interagir leurs avatars avec ceux d'autres utilisateurs, font évoluer leurs avatars dans différentes zones, et peuvent en outre acquérir des objets virtuels. Ces activités peuvent notamment leur permettre de créer des relations sociales, voire amicales, avec d'autres utilisateurs partageant par exemple les mêmes centres d'intérêts et ainsi de construire un réseau social virtuel. In virtual worlds, users have their avatars interact with those of other users, evolve their avatars in different areas, and can also acquire virtual objects. These activities can in particular allow them to create social relations, even friendly, with other users sharing for example the same centers of interests and thus to build a virtual social network.
Lorsqu'un grand nombre d'utilisateurs connectés à un service de réalité virtuelle et possédant des objets virtuels se trouvent dans une même zone du monde virtuel fourni par ledit service, par exemple pour visiter un musée, ou pour assister à un concert ou à un rassemblement quelconque, il est difficile pour un utilisateur donné de distinguer, parmi tous les objets virtuels affichés en même temps sur son terminal, ceux qui lui appartiennent et/ou ceux qui appartiennent à ses contacts dans le monde virtuel. When a large number of users connected to a virtual reality service and having virtual objects are in the same area of the virtual world provided by said service, for example to visit a museum, or to attend a concert or a concert. whatever gathering, it is difficult for a given user to distinguish, among all the virtual objects displayed at the same time on his terminal, those belonging to him and / or those belonging to his contacts in the virtual world.
L'invention vise à perfectionner l'art antérieur en proposant notamment un procédé d'affichage d'un monde virtuel permettant à l'utilisateur de reconnaître et de différencier facilement ses propres objets virtuels et/ou ceux de ses contacts dans ledit service, et ce tout en optimisant les ressources de calcul nécessaires. The invention aims to improve the prior art by proposing in particular a method for displaying a virtual world enabling the user to easily recognize and differentiate his own virtual objects and / or those of his contacts in said service, and this while optimizing the necessary computing resources.

- des moyens de modification de l'affichage desdits objets en appliquant ledit mode déterminé.  means for modifying the display of said objects by applying said determined mode.
Selon un troisième aspect, l'invention propose un serveur pour un service de réalité virtuelle, ledit serveur comprenant une application comprenant : According to a third aspect, the invention proposes a server for a virtual reality service, said server comprising an application comprising:
- des moyens de détermination de l'existence d'une relation dans le réseau social dudit service entre des objets identifiés et un utilisateur ; et means for determining the existence of a relationship in the social network of said service between identified objects and a user; and
- des moyens de détermination d'un mode d'affichage à appliquer auxdits objets. D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe représentant une architecture pour fournir à des utilisateurs un service de réalité virtuelle selon un mode de réalisation de l'invention. En relation avec cette figure, on décrit ci-dessous un procédé d'affichage d'un monde virtuel dans lequel évolue l'avatar d'un utilisateur d'un service de réalité virtuelle. Le service de réalité virtuelle est en particulier délivré par un serveur 1 dans un réseau 2 à des utilisateurs connectés audit service par l'intermédiaire de leur terminal 3, ledit terminal pouvant être par exemple un ordinateur fixe ou portable, un assistant personnel ou un smartphone. means for determining a display mode to be applied to said objects. Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figure representing an architecture for providing users with a virtual reality service according to one embodiment of the invention. In relation to this figure, a method of displaying a virtual world in which the avatar of a user of a virtual reality service evolves is described below. The virtual reality service is in particular delivered by a server 1 in a network 2 to users connected to said service via their terminal 3, said terminal can be for example a fixed or portable computer, a personal assistant or a smartphone.
Le serveur 1 peut comprendre des moyens aptes à exécuter un algorithme pour mettre en œuvre le procédé d'affichage du monde virtuel sur le terminal 3 d'un utilisateur, notamment lorsque ledit utilisateur se connecte au service de réalité virtuelle au moyen dudit terminal. The server 1 may comprise means capable of executing an algorithm for implementing the method for displaying the virtual world on the terminal 3 of a user, in particular when said user connects to the virtual reality service by means of said terminal.
A la connexion de l'utilisateur au service de réalité virtuelle, le procédé prévoit d'utiliser un mode standard d'affichage du monde virtuel dans lequel l'avatar dudit utilisateur évolue, ledit monde virtuel étant affiché sur le terminal 3 dudit utilisateur. Pour cela, le serveur 1 comprend des moyens d'affichage dans un mode standard du monde virtuel. Dans le mode standard d'affichage, l'ensemble du monde virtuel est affiché de façon uniforme, c'est-à-dire que les objets dudit monde et les avatars évoluant dans ledit monde sont affichés de la même façon, notamment avec une qualité d'affichage identique. At the user's connection to the virtual reality service, the method provides for using a standard mode of displaying the virtual world in which the avatar of said user evolves, said virtual world being displayed on the terminal 3 of said user. For this, the server 1 comprises display means in a standard mode of the virtual world. In the standard display mode, the entire virtual world is displayed uniformly, that is to say that the objects of said world and the avatars evolving in said world are displayed in the same way, in particular with a quality identical display.
Selon une réalisation, le procédé d'affichage selon l'invention peut être une option du service de réalité virtuelle que l'utilisateur peut activer, par exemple une fois qu'il est connecté audit service et que le monde virtuel dans lequel son avatar évolue est affiché dans un mode standard sur son terminal 3, ou encore en modifiant ses paramètres d'utilisation dudit service de sorte que ladite option soit automatiquement activée à sa connexion audit service. En relation avec la figure, en activant cette option, l'utilisateur envoie par l'intermédiaire de son terminal 3 une requête 4 au serveur 1 délivrant le service de réalité virtuelle, ledit serveur reprenant alors la mise en œuvre du procédé. According to one embodiment, the display method according to the invention may be an option of the virtual reality service that the user can activate, for example once he is connected to said service and the virtual world in which his avatar evolves. is displayed in a standard mode on its terminal 3, or by modifying its usage parameters of said service so that said option is automatically activated when connected to said service. In connection with the figure, by activating this option, the user sends via his terminal 3 a request 4 to the server 1 delivering the virtual reality service, said server then taking over the implementation of the method.
Le procédé prévoit ensuite d'identifier les objets visibles par l'avatar de l'utilisateur dans le monde virtuel affiché. Pour ce faire, le serveur 1 comprend des moyens d'identification des objets visibles par l'avatar, par exemple des objets affichés sur le terminal 3 de l'utilisateur dudit avatar, voire des objets les plus proches dudit avatar parmi lesdits objets affichés. En particulier, les moyens d'identification peuvent être aptes à calculer, pour chaque objet affiché, la distance entre la position actuelle de l'avatar dans le monde virtuel affiché et ledit objet, ledit objet étant alors identifié par lesdits moyens si la distance calculée est suffisamment petite. The method then provides for identifying the objects visible by the avatar of the user in the displayed virtual world. To do this, the server 1 comprises means for identifying the objects visible by the avatar, for example objects displayed on the terminal 3 of the user of said avatar, or objects closest to said avatar from said displayed objects. In particular, the identification means may be able to calculate, for each displayed object, the distance between the current position of the avatar in the displayed virtual world and said object, said object then being identified by said means if the calculated distance is small enough.
Le procédé prévoit en outre, pour au moins un des objets identifiés, de déterminer si une relation existe dans le réseau social du service de réalité virtuelle entre ledit objet et l'utilisateur. En particulier, le procédé peut prévoir de déterminer si une relation existe entre chacun des objets identifiés et l'utilisateur. The method further provides, for at least one of the identified objects, to determine whether a relationship exists in the social network of the virtual reality service between said object and the user. In particular, the method can provide for determining whether a relationship exists between each of the identified objects and the user.
Pour ce faire, le serveur 1 peut comprendre des moyens de détermination de l'existence d'une relation dans le réseau social dudit service entre les objets identifiés et l'utilisateur. To do this, the server 1 may include means for determining the existence of a relationship in the social network of said service between the identified objects and the user.
En particulier, la relation entre un objet identifié et l'utilisateur peut concerner la relation dans le réseau social entre ledit utilisateur et le possesseur dudit objet ; les moyens de détermination de l'existence d'une relation sont alors aptes à déterminer si une relation existe dans le réseau social entre ledit possesseur et ledit utilisateur. In particular, the relationship between an identified object and the user may relate to the relationship in the social network between said user and the owner of said object; the means for determining the existence of a relationship are then able to determine if a relationship exists in the social network between said owner and said user.
La relation entre l'utilisateur et un possesseur d'un objet identifié peut concerner la proximité sociale existante entre ledit utilisateur et ledit possesseur dans le réseau social. Par exemple, le possesseur de l'objet identifié peut être un contact direct de l'utilisateur dans le réseau social, comme un ami dudit utilisateur, ou un contact indirect, comme un ami d'un contact dudit utilisateur. En outre, l'utilisateur peut être lui-même le possesseur d'un des objets identifiés. The relationship between the user and a possessor of an identified object may relate to the social proximity existing between said user and said owner in the social network. For example, the owner of the identified object can be a direct contact of the user in the social network, such as a friend of said user, or an indirect contact, such as a friend of a contact of said user. In addition, the user can himself be the owner of one of the identified objects.
S'il existe une relation dans le réseau social entre un objet identifié et l'utilisateur, le procédé prévoit de déterminer un mode d'affichage à appliquer audit objet en fonction de ladite relation, l'affichage dudit objet étant alors modifié en appliquant ledit mode déterminé. If there is a relationship in the social network between an identified object and the user, the method provides for determining a display mode to be applied to said object according to said relation, the display of said object then being modified by applying said determined mode.
Pour ce faire, le serveur 1 peut comprendre des moyens de détermination d'un mode d'affichage à appliquer à des objets en fonction de leur relation avec l'utilisateur et des moyens de modification de l'affichage desdits objets en appliquant ledit mode déterminé. To do this, the server 1 may comprise means for determining a display mode to be applied to objects according to their relationship with the user and means for modifying the display of said objects by applying said determined mode .
Selon une réalisation représentée, un serveur 5 externe peut être implémenté dans l'architecture préexistante de fourniture du service de réalité virtuelle et peut comprendre une application comprenant : According to one embodiment shown, an external server 5 may be implemented in the pre-existing virtual reality service provisioning architecture and may include an application comprising:
- les moyens de détermination de l'existence d'une relation dans le réseau social dudit service entre les objets identifiés et l'utilisateur ; et  means for determining the existence of a relationship in the social network of said service between the identified objects and the user; and
- les moyens de détermination d'un mode d'affichage à appliquer auxdits objets.  - The means for determining a display mode to be applied to said objects.
En relation avec la figure, le serveur 1 peut comprendre des moyens pour envoyer, pour chaque objet identifié, une requête 6 au serveur 5, afin d'obtenir le mode d'affichage à appliquer audit objet en fonction de sa relation avec l'utilisateur. In connection with the figure, the server 1 may comprise means for sending, for each object identified, a request 6 to the server 5, in order to obtain the display mode to be applied to said object as a function of its relationship with the user. .
En outre, le serveur 5 peut comprendre des moyens pour envoyer une notification 7 au serveur 1 en réponse à chaque requête 6 envoyée, ladite notification comprenant le mode d'affichage déterminé par l'application pour l'objet identifié correspondant. In addition, the server 5 may comprise means for sending a notification 7 to the server 1 in response to each request 6 sent, said notification comprising the display mode determined by the application for the corresponding identified object.
Selon une autre réalisation non représentée, l'application précitée peut être intégrée au serveur 1 de fourniture du service de réalité virtuelle. Selon un mode de réalisation, le procédé prévoit de modifier la qualité d'affichage d'un objet en fonction de la relation déterminée entre ledit objet et l'utilisateur. Par exemple, les moyens de modification du serveur 1 peuvent être aptes à modifier la résolution d'un objet identifié, ou la quantité de détails dudit objet, ou encore la netteté dudit objet, et ce en fonction de la relation entre ledit objet et l'utilisateur. According to another embodiment not shown, the aforementioned application can be integrated with the server 1 for providing the virtual reality service. According to one embodiment, the method provides for modifying the display quality of an object as a function of the determined relationship between said object and the user. For example, the means for modifying the server 1 may be able to modify the resolution of an identified object, or the quantity of details of said object. object, or the sharpness of said object, and this according to the relationship between said object and the user.
En particulier, la qualité d'affichage d'un objet peut être modifiée de façon à améliorer la perception visuelle par l'utilisateur dudit objet en fonction du degré de la relation entre ledit objet et ledit utilisateur. In particular, the display quality of an object can be modified to improve the visual perception by the user of said object as a function of the degree of the relationship between said object and said user.
Le degré de la relation entre un objet identifié et l'utilisateur peut en particulier être lié au niveau de proximité sociale entre ledit utilisateur et le possesseur dudit objet, les moyens de détermination de l'existence d'une relation étant aptes à déterminer ledit degré en fonction dudit niveau, notamment selon une échelle prédéfinie. The degree of the relationship between an identified object and the user can in particular be related to the level of social proximity between said user and the owner of said object, the means for determining the existence of a relationship being able to determine said degree. according to said level, in particular according to a predefined scale.
Pour ce faire, les moyens de détermination de l'existence d'une relation peuvent être aptes à interroger une base de données du réseau social du service de réalité virtuelle afin de déterminer le degré de la relation entre un objet identifié et l'utilisateur selon une échelle prédéfinie. To do this, the means for determining the existence of a relationship may be able to query a database of the social network of the virtual reality service to determine the degree of the relationship between an identified object and the user according to a predefined scale.
Selon une réalisation, le serveur 5 externe peut comprendre une base de données dans laquelle sont enregistrées les relations existantes entre les différents utilisateurs du service de réalité virtuelle, les moyens de détermination de l'existence d'une relation étant aptes à interroger ladite base. According to one embodiment, the external server may comprise a database in which the existing relationships between the different users of the virtual reality service are recorded, the means for determining the existence of a relation being able to interrogate said base.
Par exemple, si le possesseur d'un objet identifié est un contact indirect de l'utilisateur dans le réseau social du service de réalité virtuelle, le degré de la relation entre ledit objet et ledit utilisateur sera moyen. For example, if the owner of an identified object is an indirect contact of the user in the social network of the virtual reality service, the degree of the relationship between said object and said user will be average.
De même, si le possesseur d'un objet identifié est un contact direct de l'utilisateur dans le réseau social du service de réalité virtuelle, le degré de la relation entre ledit objet et l'utilisateur sera élevé. Similarly, if the owner of an identified object is a direct contact of the user in the social network of the virtual reality service, the degree of the relationship between said object and the user will be high.
En outre, si le possesseur d'un objet identifié est l'utilisateur lui-même, le degré de la relation entre ledit objet et l'utilisateur sera très élevé. Enfin, s'il n'existe pas de relation entre le possesseur de l'objet identifié et l'utilisateur dans le réseau social du service de réalité virtuelle, ou si cette relation est trop éloignée, les moyens de détermination de l'existence d'une relation peuvent être aptes à déterminer qu'il n'existe pas de relation entre ledit objet et l'utilisateur, et le procédé ne modifiera pas l'affichage dudit objet. In addition, if the owner of an identified object is the user himself, the degree of the relationship between said object and the user will be very high. Finally, if there is no relationship between the owner of the identified object and the user in the social network of the virtual reality service, or if this relationship is too far away, the means for determining the existence of a relationship may be able to determine that there is no relationship between said object and the user, and the method will not change the display of said object.
En fonction du degré de la relation entre un objet et l'utilisateur, les moyens de détermination d'un mode d'affichage sont aptes à déterminer le mode d'affichage approprié à appliquer audit objet afin d'améliorer la perception visuelle par l'utilisateur dudit objet. Depending on the degree of the relationship between an object and the user, the means for determining a display mode are able to determine the appropriate display mode to be applied to said object in order to improve the visual perception by the user. user of said object.
En particulier, le mode d'affichage peut être déterminé de sorte à améliorer la qualité d'affichage d'un objet de façon proportionnelle au degré de la relation entre ledit objet et l'utilisateur. En outre, des modes d'affichage correspondant chacun à un degré de relation entre un objet et l'utilisateur peuvent être prédéfinis dans le service de réalité virtuelle, les moyens de détermination d'un mode d'affichage étant aptes à sélectionner un desdits modes prédéfinis en tant que mode d'affichage à appliquer à un objet en fonction du degré de sa relation avec l'utilisateur. In particular, the display mode can be determined so as to improve the display quality of an object proportionally to the degree of the relationship between said object and the user. In addition, display modes each corresponding to a degree of relationship between an object and the user can be predefined in the virtual reality service, the means for determining a display mode being able to select one of said modes. predefined as the display mode to apply to an object according to the degree of its relationship with the user.
Par exemple, si le degré de la relation entre un objet et l'utilisateur est très élevé, par exemple parce l'utilisateur est le possesseur dudit objet, le mode d'affichage à appliquer audit objet sera celui correspondant à la meilleure qualité d'affichage. For example, if the degree of the relationship between an object and the user is very high, for example because the user is the owner of said object, the display mode to be applied to said object will be that corresponding to the best quality of the object. display.
De même, si le degré de la relation entre un objet et l'utilisateur est élevé, par exemple parce que le possesseur dudit objet est un contact direct dudit utilisateur, le mode d'affichage à appliquer audit objet sera celui correspondant à une bonne qualité d'affichage. Similarly, if the degree of the relationship between an object and the user is high, for example because the owner of said object is a direct contact of said user, the display mode to be applied to said object will be that corresponding to a good quality display.
En outre, si le degré de la relation entre un objet et l'utilisateur est moyen, par exemple parce que le possesseur dudit objet est un contact indirect dudit utilisateur, le mode d'affichage à appliquer audit objet sera celui correspondant à une qualité d'affichage moyenne. In addition, if the degree of the relationship between an object and the user is average, for example because the owner of said object is an indirect contact of said user, the display mode to be applied to said object will be that corresponding to an average display quality.
Enfin, s'il n'existe pas de relation entre un objet et l'utilisateur, ou si le degré de ladite relation est trop faible, le procédé ne modifiera pas l'affichage dudit objet. Finally, if there is no relationship between an object and the user, or if the degree of said relationship is too low, the method will not change the display of said object.
Ainsi, le procédé d'affichage permet, grâce à une technologie basée sur un affichage par téléchargement continu adapté, d'améliorer le réalisme du monde virtuel en imitant l'un des principaux mécanismes de la perception humaine. En effet, en modifiant positivement la qualité d'affichage des objets visibles par l'avatar de l'utilisateur et familiers dudit utilisateur, le procédé permet audit utilisateur de repérer plus facilement lesdits objets parmi d'autres objets non familiers, lesdits autres objets étant affichés dans un mode standard de qualité basique. Thus, the display method makes it possible, thanks to a technology based on a suitable continuous download display, to improve the realism of the virtual world by imitating one of the main mechanisms of human perception. By positively modifying the display quality of the objects visible by the avatar of the user and familiar to the said user, the method enables the user to more easily locate said objects among other unfamiliar objects, said other objects being displayed in a basic quality standard mode.
En relation avec la figure, après réception par le serveur 1 d'une notification 7 comprenant le mode d'affichage à appliquer à un objet, les moyens de modification de l'affichage envoient une notification 8 au terminal 3 de l'utilisateur afin que les moyens d'affichage dudit terminal appliquent ledit mode audit objet pour modifier l'affichage dudit objet en fonction de sa relation avec l'utilisateur. In connection with the figure, after reception by the server 1 of a notification 7 comprising the display mode to be applied to an object, the means for modifying the display send a notification 8 to the terminal 3 of the user so that the display means of said terminal apply said mode to said object to modify the display of said object according to its relationship with the user.
Selon un autre mode de réalisation, le procédé peut prévoir de modifier la qualité d'affichage d'un objet de façon inversement proportionnelle au degré de sa relation avec l'utilisateur. Par exemple, les modes d'affichage prédéfinis peuvent porter sur un niveau de floutage d'un objet, ledit niveau de floutage étant inversement proportionnel au degré de la relation entre ledit objet et l'utilisateur. En particulier, le service de réalité virtuelle peut comprendre une échelle prédéfinie de détermination du degré d'une relation, le niveau le plus bas de ladite échelle correspondant au cas ou il n'existe pas de relation dans le réseau social dudit service entre un utilisateur et le possesseur d'un objet identifié, ou au cas où la relation entre ledit utilisateur et le possesseur dudit objet est trop éloignée. According to another embodiment, the method may provide for modifying the display quality of an object inversely proportional to the degree of its relationship with the user. For example, the predefined display modes may relate to a level of blurring of an object, said blur level being inversely proportional to the degree of the relationship between said object and the user. In particular, the virtual reality service may comprise a predefined scale for determining the degree of a relationship, the lowest level of said scale corresponding to the case where there is no relationship in the social network of said service between a user and the possessor of an identified object, or in the case where the relationship between said user and the owner of said object is too far away.
