Abstract: A virtual reality (VR) or augmented reality (AR) system detects through a camera when a user's hand positions match a predefined position and in response thereto renders an overlay including a crown with which the user can interact to lock onto an object or scene. The system then detects and renders a centre indicator of the crown, tracking the user's hands, enables or disables actions depending on the position of the centre indicator relative to a neutral zone, responds to user hand movement to implement actions, and also detects unlock of the object or scene.

Abstract: A sequence of point clouds is encoded as a video by an encoder and transmitted to a decoder which retrieves the sequence of point clouds. Visible points of a point cloud are iteratively projected on projection maps according to at least two centers of projection, to determine a patch data item lists. One of the centers of projection is selected and corresponding image patches are generated and packed into a picture. Pictures and associated patch data item list are encoded in a stream. The decoding method decodes pictures and associated patch data item lists. Pixels of image patches comprised in pictures are un-projected according to data stored in associated patches. The methods have the advantage of encoding every point of point clouds in a manner avoiding artifacts and allowing decoding at video frame rate.

Abstract: The present disclosure relates to the transmission of sets of data and metadata and more particularly to the transmission of light-field contents. Light-field data take up large amounts of storage space which makes storage cumbersome and processing less efficient. In addition, light-field acquisition devices are extremely heterogeneous and each camera has its own proprietary file format. Since acquired light-field data from different cameras have a diversity of formats a complex processing is induced on the receiver side. To this end, it is proposed a method for encoding a signal representative of a light-field content in which the parameters representing the rays of light sensed by the different pixels of the sensor are mapped on the sensor. A second set of encoded parameters are used to reconstruct the light-field content from the parameters representing the rays of light sensed by the different pixels of the sensor.

Abstract: Methods and systems are provided for establishing dynamic and secure peer-to-peer communications channels between terminals. A network device may intercept a connection request transmitted from a first terminal to a second terminal, over a secure network, with the connection request including a first parameter that identifies the first terminal and a second parameter that identifies the second terminal, with the first parameter and the second parameter relating to a network interface that operates according to a security protocol. The network device may then send instructions to the first terminal to establish peer-to-peer communications with the second terminal over a secured ad-hoc public network, using one or more keys provided by a central unit of that network. The keys may include an authentication key, which may be used in authenticating one or both of the terminals, and/or an encryption key, which may be used in encrypting the peer-to-peer communications.

Abstract: Dynamic virtual content(s) to be superimposed to a representation of a real 3D scene complies with a scenario defined before run-time and involving real-world constraints (23). Real-world information (22) is captured in there al 3D scene and the scenario is executed at runtime (14) in presence of there al-world constraints. When there al-world constraints are not identified (12) from there al-world information, a transformation of the representation of the real 3D scene to a virtually adapted 3D scene is carried out (13) before executing the scenario, so that the virtually adapted 3D scene fulfills those constraints, and the scenario is executed in the virtually adapted 3D scene replacing the real 3D scene instead of there al 3D scene. Application to mixed reality.
