A photograph of a black laptop open on a light wooden table in a room with a patterned upholstered armchair, a white wall-mounted air conditioner, and a black tripod. The laptop screen shows a dark blue software interface with a red curve graph and two numeric readouts, 0.55 and 94.76. A white USB device is plugged into the side of the laptop, and a tissue box and papers sit beside it. A blue-jeaned leg is visible at the right edge. No people are clearly visible as subjects; the scene shows equipment and furnishings only.
