This image depicts an indoor classroom or lecture hall at the Universidad Autónoma de Madrid in Madrid, Spain. A person, partially visible on the far left with a dark, polka-dotted garment, is seated at a wooden desk with an open notebook containing handwritten notes in Spanish and two pens (one black, one purple). Directly ahead, another wooden desk holds a closed black laptop, a dark-colored smartphone, and a black bag. Behind this desk, a wooden chair with a metal frame displays a white sticker featuring a barcode and "UAM" text. The background is dominated by a brightly lit projection screen or large display. The screen presents a slide titled "estructura triádica del significado" (triadic structure of meaning), featuring a green equilateral triangle with labels "INTERPRETANTE" at the top, "OBJETO" partially visible on the bottom left, and "SIGNO" on the bottom right. A red oval encompasses the triangle. The wall behind the screen is covered with light brown textured panels. The lighting is dim, highlighting the illuminated screen.
