A communications interface and a communications method, a corresponding computer program, and a corresponding registration medium

Communications interface for communications between participants who have respective screens at their disposal, said interface including a two-dimensional virtual space (1) and avatars (2, 3, 4, 5, 6, 7, 8, 9, 10, 11) two-dimensional graphics which firstly represent the respective of said participants and secondly they are designed to move in said virtual space (1), said virtual space (1) and said avatars (2, 3, 4, 5, 6, 7, 8, 9, 10, 11) graphics designed to be displayed on said screens, said communication interface also including control means that allow each of the participants to control the movements of their avatars (2, 3, 4, 5, 6, 7, 8, 9, 10, 11) respective graphics, said communication interface automatically establishing a discussion channel between two of said participants when the distances (d ') between an object (12, 13, 14) graphic located in said virtual space (1) and each of the two avatars (2, 3) graphics representing the respective of said two participants are less than or equal to a second predetermined value (D2), allowing the establishment of said discussion channel that said two participants converse with each other, in real time, through audio-video communication with a video window that emerges in the graphic avatar of each participant in question, said graphic object (12, 13, 14) being a window that can be activated / deactivated designed to activate for all of said participants that are represented by respective graphic avatars when the distance (d ') between each of said respective graphic avatars and said graphic object is less than or equal to a second predetermined value (D2), allowing the activation of said graphic object that the interaction takes place between said graphic object and each one of said participants who have their respective avatars far from said graphic object (12, 13, 14) in said distance (d ') less than or equal to the second default value (D2), said activation corresponding to the broadcasting of audiovisual content that is perceived only by said participants who have their respective avatars at a distance (d ') from said graphic object (12, 13, 14) that is less than or equal to said second value (D2) default, automatically ceasing broadcasting for participants who move their graphic avatars away from the graphic object (12, 13, 14) at distances (d ') greater than the second default value (D2), the other participants having their avatars still having access at a distance (d ') from said graphic object (12, 13, 14) that is less than or equal to said second predetermined value (D2) to the content that is being broadcast by broadcast.
