BFI captures how a human body distorts the wireless channel, enabling passive occupancy detection.

Prompt: A floor plan view of a room showing a Wi-Fi access point in one corner and a human silhouette standing in the centre. Curved signal wavefronts radiate from the access point, interact with the human figure, and reflect in altered patterns back toward a passive receiver positioned outside the room. The difference in wave patterns around the human figure versus the empty space is clearly visible, suggesting occupancy detection from wireless signals alone. Style: Detailed digital illustration blending technical schematic linework with painterly atmospheric rendering, as if a scientific textbook were reimagined by a noir graphic novelist. Colour palette of deep midnight blue, charcoal black, and slate grey as foundations, accented with electric teal, bioluminescent green, and cold amber. Lighting is dramatic and directional, suggesting surveillance or laboratory environments — pools of cold light against deep shadow, with occasional glowing circuit-trace highlights. Compositions favour tight framing with layered depth: foreground technical detail dissolving into abstracted background geometry. Detail level is high but purposeful, prioritising legible structure over decorative complexity. Mood is clinical yet ominous, precise yet unsettling. No text, lettering, captions, logos, watermarks or borders unless it is a technical drawing.
