This image shows a classroom or lecture hall located in Porto Salvo, Portugal. The perspective is from a student's desk in the immediate foreground, where the top of a laptop screen displaying code or data and a tablet screen showing a clock application are visible. In the mid-ground, several students are seated at individual desks with light-colored wooden tops and black metal frames, accompanied by matching chairs. Students are observed from behind; one wears a light grey long-sleeved shirt, and another wears a dark blue sweater. To the far left, a silver laptop is open on another desk. At the front of the room, a male individual with dark hair and a beard stands in front of a white whiteboard, facing away from the camera, indicating a teaching or presentation role. The whiteboard contains handwritten mathematical equations and diagrams. Adjacent to the whiteboard, a large projection screen displays what appears to be a spreadsheet or a table of data. The room is illuminated by natural light entering through two large windows on the left wall, covered by closed blue curtains, and by artificial light from several rectangular fluorescent fixtures mounted on the white suspended ceiling. The ceiling also features two recessed air conditioning vents and a single, circular smoke detector.
