Measurement Protocols for Medium-Field Distance Perception in Large-Screen Immersive Displays
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 mediumfield distances of 2 to 15 meters. The experiment measured egocentric depth judgments in a CAVE, a tiled display wall, and a realworld 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 underestima...
