Interior wall with a virtual window device (10; 110; 210), comprising: a bezel with a display arranged within the bezel at the interior wall; a distance sensor unit (16; 116) configured to produce at least one first distance signal (191-1, 191-2) indicating first respective distances between faces of users (261, 262) in front of the display and a common reference point at or adjacent to the display; a first camera unit configured to capture a live video of a real scene from a space behind the display on the other side of the interior wall as the display; a second camera unit configured and arranged to capture a picture or a video of a space in front of the display; a face recognition module configured to recognize faces (261, 262) in the captured picture or video of the space in front of the display, to determine spatial orientations of the recognized faces (261, 262) and to produce face orientation signals indicating at least the determined spatial orientations of the recognized faces (261, 262); and a computing unit (20; 120; 220) configured: to select, based on the at least one first distance signal (191-1, 191-2) for each recognized face (261, 262), a position signal indicating a position of each recognized face (261, 262) with respect to the common reference point, to calculate, based on the plurality of face orientation signals, a viewing angle between a viewing axis of each recognized face (261, 262) and a predetermined main viewing axis of the display for each recognized face (261, 262), to determine a preferred face among the plurality of recognized faces (261, 262) based on the position signals and on the calculated viewing angles, to select a section of the live video of the real scene captured by the first camera unit such that, based on the face orientation signal belonging to the preferred face, the selected section is identical to a hypothetical section that a person with a face having the spatial orientation of the preferred face would see through the bezel if the bezel surrounded an opening or a window instead of the display, and to control the display to display the selected section. a bezel with a display arranged within the bezel at the interior wall;
