Table 1.

Results from Experiment 3. Each row shows the data for a different observer. The first column provides the observers’ initials. The second indicates the experimental condition. The third shows the data from the conventional display condition, and the fourth column shows the data from the volumetric display condition. The entries in the third and fourth columns are the slopes of the linear-regression fits to the data in Figure 10. The entries in the cues-inconsistent condition are the averages of the three regression-line slopes for each observer. The entries in the cues-consistent, between-sessions condition are the fits to the cues-consistent data across the three inconsistent sessions (near, mid, and far vergence and focal distance). The entries in the cues-consistent, within-session condition are the fits to the data obtained with the volumetric display when focal and vergence distance were changed from trial to trial but were always equal to one another. The entries at the bottom of the table are the slopes averaged across observers.
