Abstract
How do users of virtual environments perceive virtual space? Many experiments have explored this question, but most of these have used head-mounted immersive displays. This paper reports an experiment that studied large-screen immersive displays at medium-field distances of 2 to 15 meters. The experiment measured egocentric depth judgments in a CAVE, a tiled display wall, and a real-world outdoor field as a control condition. We carefully modeled the outdoor field to make the three environments as similar as possible. Measuring egocentric depth judgments in large-screen immersive displays requires adapting new measurement protocols; the experiment used timed imagined walking, verbal estimation, and triangulated blind walking. We found that depth judgments from timed imagined walking and verbal estimation were very similar in all three environments. However, triangulated blind walking was accurate only in the outdoor field; in the large-screen immersive displays it showed underestimation effects that were likely caused by insufficient physical space to perform the technique. These results suggest using timed imagined walking as a primary protocol for assessing depth perception in large-screen immersive displays. We also found that depth judgments in the CAVE were more accurate than in the tiled display wall, which suggests that the peripheral scenery offered by the CAVE is helpful when perceiving virtual space.

How do users of virtual environments perceive virtual space? Many experiments
have explored this question, but most of these have used head-mounted
immersive displays. This paper reports an experiment that studied
large-screen immersive displays at medium-field distances of 2 to 15 meters.
The experiment measured egocentric depth judgments in a CAVE, a tiled display
wall, and a real-world outdoor field as a control condition. We carefully
modeled the outdoor field to make the three environments as similar as
possible. Measuring egocentric depth judgments in large-screen immersive
displays requires adapting new measurement protocols; the experiment used
timed imagined walking, verbal estimation, and triangulated blind walking.
We found that depth judgments from timed imagined walking and verbal
estimation were very similar in all three environments. However, triangulated
blind walking was accurate only in the outdoor field; in the large-screen
immersive displays it showed underestimation effects that were likely caused
by insufficient physical space to perform the technique. These results
suggest using timed imagined walking as a primary protocol for assessing depth
perception in large-screen immersive displays. We also found that depth
judgments in the CAVE were more accurate than in the tiled display wall, which
suggests that the peripheral scenery offered by the CAVE is helpful when
perceiving virtual space.
