  • Columns indicate the different tasks, and rows indicate the mean comparisons, grouped according to columns (head coordinates), rows (world coordinates), and diagonals (body orientation) in Figs. 2, 4, 5, and 7. Bold indicates p < 0.01. Thresholds correspond to the 84% correct level for each task.
