In one exemplary embodiment, a method is performed by a controller device that is coupled to at least one of a set of display devices that are spatially arranged so that each display device is positioned adjacent to at least one other display device and wherein each display device includes a screen structure having a set of presence sensitive sensors. Each display device is operable, for each presence sensitive sensor of the corresponding screen structure, to detect a presence signal and to radiate a presence signal. The method includes receiving an indication that a second display device of the set of display devices has detected a presence signal radiated from a presence sensitive sensor of a first display device of the set of display devices so as to determine a spatial arrangement of the first and second display devices. ## Claims ### Claim 1 A method, comprising: by a controller device that is coupled to each of a set of display devices that are spatially arranged so that each display device is positioned adjacent at least one other display device and wherein each display device includes a screen structure having a set of presence sensitive sensors, with each display device being operable, for each presence sensitive sensor of a corresponding screen structure, to detect a presence signal and to radiate a presence signal, initiating a timer associated with determining that a detection of the radiated presence signal is within a certain time period after the presence signal is radiated;
