Figure 3.

Four scientific data visualizations compare pupil diameter and blink rate during three agricultural tasks: baling, rotary tillage, and sowing. Violin plots (left) display overall distributions for each task. Line charts (right) show trends across five operational cycles, with baling consistently showing larger pupil diameters and lower blink rates, and rotary tillage showing the opposite. Significant main and interaction effects are noted.

Bidirectional divergence and nonlinear temporal evolution of visual channel responses. (A) Probability density distributions of pupil diameter and blink rate across the three agricultural tasks (N = 12). Violin plots with internal boxplots depict inter-subject variance. (B) Longitudinal trajectories of visual metrics across the 5-hour operational cycles. Shaded bands represent the 95% confidence intervals (CI). p < 0.001***.
