Abstract: A human-machine interface system includes at least one visual interaction device having image-capturing means and display means and computerized means executing an interface allowing a user to interact with the visual interaction device. The system presenting the user with an at least partially virtual content item, in particular, for augmented reality, the interaction device capturing the real environment of the user to provide it to the interface, which generates a mesh of the environment and tracks the user's gaze, the interface being configured to detect when the user's gaze is oriented toward the ground and to start a launcher that is presented to the user via the interaction device in the form of at least one navigation content item including a plurality of graphical elements that the user is able to scroll through with their gaze and that are representative of a function to which they correspond.

Abstract: Disclosed is a device (1) for moving in virtual reality including a substantially rigid node (4) and an envelope (5) arranged so as to be capable of movement in all directions about the node (4), the envelope (5) defining with the node (4) a surface for the movement of a person (2), and the assembly defined by the node and the envelope bearing on an appropriate bearing element (6). The envelope can be mounted so as to slide against the node, or at least a portion of the node.

Abstract: The invention concerns a method and a device for shooting spherical pictures to produce a succession of digitised images about an object (6), in order to subsequently enable a three-dimensional observation of said object by computer means. The invention is in particular useful for producing digitised film representing an object rotating about its centre of rotation.
