Abstract: A method and corresponding device for processing virtual-reality environment data, wherein at least one part of the body of a user of the virtual-reality environment is detected. The part of the body of the user is capable of interacting with at least one object of the virtual-reality environment. At least one sound signal is generated according to the detection of the at least one part of the body of the user of the virtual-reality environment.

Abstract: A virtual reality data-processing device, intended to be worn on the head of a user is disclosed. The device renders, in a field of view of the data-processing device, a virtual interaction interface, at least one part of the virtual interaction interface being rendered superimposed on a tangible device, when the tangible device is located in the field of view of the data-processing device, track at least one body part of the user likely to interact via the virtual interaction interface, detect at least one user interaction on a virtual element of the virtual interaction interface, when the at least one body part of the user is close to or in contact with the tangible device. The development also relates to a system and a method for processing virtual reality data.

Abstract: A method of supervising the activity of a user in a virtual world comprising the steps of: (1) detecting at least one item of collision information between an observation line associated with the user and at least one first virtual object within the virtual world; and (2) determining at least one item of interaction information between the user and the first object on the basis of the collision information.
