The ground dominance effect in the perception of relative distance in 3-D scenes is mainly due to characteristics of the ground surface
|
Previously, we (Bian, Braunstein, & Andersen, 2005) reported a dominance effect of the ground plane over other environmental surfaces in determining the perceived relative distance of objects in 3-D scenes. In the present study, we conducted three experiments to investigate whether this ground dominance is due to inherent differences between ground and ceiling surfaces, or to the locations of these surfaces in the visual field. In Experiment 1, two vertical posts were positioned between a...

Perceived relative distance on the ground affected by the selection of depth information
Perception and Psychophysics
; Our visual space does not appear to change when we scan or shift attention between locations. This appearance of stability implies that the depth information selection process is not crucial for constructing visual space. But we present evidence to the contrary. We focused on space perception in

The ground dominance effect in the perception of 3-D layout
Perception and Psychophysics
; The relative effectiveness of the ground surface and other environmental surfaces (the ceiling and sidewalls) in determining perceived layout was investigated in five experiments and a real-world demonstration. In the first three experiments, two vertical or horizontal posts were positioned between

2-D roughness gaging doesn't tell the whole story
Manufacturing Engineering
; For more than half a century, manufacturers have used two-dimensional (2-D) profilometry to measure and characterize surface roughness. The technique has proven convenient, economic, and efficient. Until recently, few users have questioned whether the 2-D profile describes the 3-D surface

The linear perspective information in ground surface representation and distance judgment
Perception and Psychophysics
; Most ground surfaces contain various types of texture gradient information that serve as depth cues for space perception. We investigated how linear perspective, a type of texture gradient information on the ground, affects judged absolute distance and eye level. Phosphorescent elements were used
