A first communication device, e.g., having a camera, is pointed, by a first person, in direction of a second person with which the first person wants to communicate in an interactive session, using his communication device. The camera captures the face of the second person. If the second person does not have a device enabling interaction with the first device, a third person in proximity of the second person, having a device enabling interaction, is selected, and a request is transmitted to the second device in the hands of the third person to handover his device to the second person, displaying, for example, the face of the second person. When handover is detected, the second person may be identified by the device being handed over. The interaction between the first and the second device may be established.

Method and apparatus for establishing a communication between a first and a second communication device

A method and device are provided for processing images. In one embodiment, the method comprises receiving an image is received of a scene having a plurality of real objects and determining if at least one of these real objects is a reference object stored in a database. Subsequently, candidate shadow map of the reference object identified is retrieved when available and when a reference object cannot be identified, an object in the scene with adequate parameters is selected and the candidate shadow maps of this new reference object using said lighting parameters is computed.

A method, apparatus and system for facilitating navigation toward a region of interest in an extended scene of video content include determining a timeline including information regarding at least one region of interest in the video content and displaying, in a portion of the video content currently being displayed, a visual indicator indicating a direction in which to move in the video content to cause the display of the at least one region of interest. In one embodiment of the present principles a timeline is attached to the content and carries information evolving over time about the region(s) of interest. A renderer processes the timeline and provides navigation information to a user using available means such as a graphical representation or haptic information, or a combination of several means.

Localization of a user device in a mixed reality environment in which the user device obtains at least one keyframe from a server, which can reside on the user device, displays at least one of the keyframes on a screen, captures by a camera an image of the environment, and obtains a localization result based on at least one feature of at least one keyframe and the image.

Device and method for device localization

A method of sharing and a method of presenting virtual content in a mixed reality scene rendered on at least two user devices having different viewing position and/or orientation onto the mixed reality scene and corresponding apparatus are described. At a first user device, a user is enabled to select a virtual content to be shared and a second user device with whom the virtual content is to be shared. Information related to the virtual content to be shared is provided, wherein the provided information comprises the 3D position of the virtual content to be shared. The information is received by the second user device and the shared virtual content is rendered with regard to the viewing position and/or orientation of the second user device onto the mixed reality scene.

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 (). Real-world information () is captured in there al 3D scene and the scenario is executed at runtime () in presence of there al-world constraints. When there al-world constraints are not identified () from there al-world information, a transformation of the representation of the real 3D scene to a virtually adapted 3D scene is carried out () 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.

The disclosure relates to a method for generating an augmented representation of a real environment, called an augmented reality representation. Such a method includes obtaining, as a function of said real environment, a virtual boundary dividing the real environment into two spaces, respectively called an activity space and a mixed space. The augmented reality representation is generated by obtaining a first part of the augmented reality representation, called an activity part, corresponding to a representation of at least one part of the activity space. Thereafter, obtaining a second part of the augmented reality representation, called a mixed part, corresponding to an augmented representation of at least one part of the mixed space, in which at least one virtual content is combined with the representation of at least one part of the mixed space.

The present disclosure relates to methods, apparatus and systems for automatically adapt the zoom coefficient of the camera of a system when running an augmented reality application. A pose estimation is performed for the camera which captures the real scene and the boundaries of the AR scene are calculated. According to the camera frustum and the boundaries, three-dimension rectangles are computes to determine a zoom coefficient that would optimize the seeing of the seen and the optimal position for the camera. The zoom is automatically optically or digitally adapted and the optimal position is indicated to the user by visual, audio or haptic means.

A method of decoding an audio/video content transmitted over a broadband network. The method being based on the quick decoding of the first frames of a group of pictures without rendering them if the group of pictures arrives too late to be rendered synchronously with another audio/video content received through a broadcast network. The method allowing the synchronized rendering of contents respectively received over broadcast and broadband networks as soon as possible for the viewer.

A method and device for rendering a scene including one or more real objects is described. A virtual object is associated with each real object, a virtual object associated with a real object corresponding to a virtual replica of this real object. The virtual replica is used to render a transformation that may be applied to the real object when for example hit by a virtual object, the virtual object then replacing the corresponding real object within the scene. To bring realism to the scene, texture information obtained from image(s) of the real object(s) is used to texture the visible part(s) of the transformed virtual object(s). The texture information is selected in the images by using information on the visibility of the parts of the real object(s) that correspond to the visible parts of the transformed virtual object(s).

A method for controlling a rendering time of a second video content stream on a second device to be synchronized with a rendering time of a first video content stream on a first device, said second video content stream being organized in chunks, includes receiving by a control device a request of a chunk of the second video content stream from the second device, receiving by the control device, the packets of the requested chunk, and delivering by the control device the requested chunk to the second device at a delivery time at which said requested chunk should be delivered to the second device so that the rendering time of the second video content stream on the second device is synchronized with the rendering time of the first video content stream on the first device.
