Abstract: A system and method for intercommunication among the members of a team employing user devices, organized around maps of the locations of the team members presented on the display screens of the user devices. Team members manage intercommunications among themselves by selections made according to the displayed maps and icons thereon. The maps provide a flexible framework around which to structure various modalities of intercommunication including chat, voice, audio-video camera streaming, or a data stream from a sensor, which are graphically indicated on the maps. Organizing and managing according to icons of team members on the maps provides flexible intercommunication without excessive constraint, facilitating intuitive and easy operation. When posting of geographical location of a team member is not desired, a ghost mode permits a team member to freely interact with the group without divulging location.
