Abstract: Method and device for rendering environments, in particular virtual environments. The device can include 2D and 3D rendering devices, such as virtual-reality headsets, holographic devices, etc. The method includes, when rendering a first environment: detecting parameters relating to an avatar, for rendering the first environment, the detecting being triggered by a command to move the avatar into a second environment, the detected rendering parameters are thus suitable for use in a first phase of rendering the second environment; and in the first phase of rendering the second environment, inserting a preview object containing the second environment into the first environment. Thus, when a second environment is rendered after rendition of the first environment, the user is not projected directly into the second environment. This decreases risk of motion sickness and fatigue due to leaps. Additionally, the user can anticipate the second environment, avoiding a risk of disorientation.

Abstract: A method for accessing a first secure communication session, referred to as a first session, in progress between participating communication terminals, referred to as participating terminals, by a requesting communication terminal, referred to as a requesting terminal. The access method includes: triggering an entry into the first session in progress of the requesting terminal on receipt of an acceptance from one of the participating terminals following a transmission of an access request message sent by the requesting terminal to at least one participating terminal of the first session. Hence, the requesting terminal will easily access the first secure communication session even if the requesting terminal does not follow the secure access procedure.

Abstract: The invention relates to the adaptation of the user interface to an interaction context. An object of the invention is a method for adapting a user interface of at least one application implemented by a user terminal comprising a modification of at least one parameter of said user interface on said user terminal according to a change of context of interaction of the user with said user interface, one of said at least one modified parameters is an interaction parameter. Thus, the mode of interaction of the interface is also adapted to the interaction context. This means, in our example, that the user can switch automatically or manually from a “hands-on” mode to a “hands-off” mode enabling him or her, for example, to interact with his or her screen from several points of his or her kitchen without systematically going over to the latter.

Abstract: The invention concerns an instance of use of a content library, in particular the interactive viewing of the content of the library. A subject of the invention is a method for using content of a content library comprising, following an instance of use of at least one content of a library, an instance of generation of a plurality of content clusters from the content of the library according to one or more criteria associated with the clusters, the criteria having been determined according to at least one previously used content, the generated clusters being selectable by a user, an instance of selection of a cluster triggering an instance of use of the content of the selected cluster. Thus, the proposed content groupings or clusters for the user have a greater probability of being selected by the user than content files classified by date or subject since they are devised by taking account of the previously used content.

Abstract: A method is provided for generating personalized playlists for reproducing contents in relation to the experience of an event by a user of a communication terminal. The method includes determining at least two distinct elements as a function of data provided by the communication terminal of the user and of data relating to the event which are made available by a device for providing services concerning the event. Each of the elements makes it possible to determine at least one content made available by at least one device for providing contents, wherein the contents thus determined for each element are integrated into a playlist. Thus, the playlist is not only generated automatically but in addition it is associated with an event and personalized as a function of the experience of this event by a user.
