A system and method for sharing information between users based on recognition of the users and their associated processing devices in a scene. Interactions can be physical, verbal or a combination of physical and verbal gestures. Movements of the user and other users are tracked and interactions detected between them. User processing devices are connected by detecting users within view of a capture device, the capture device detecting motion tracking data for the user, such as a skeletal model. Information sharing may be controlled by the processing devices directly, by an intermediary server, or by a combination of the processing device and an intermediary server.
