“…These results were consistent with the results of previous studies showing superior encoding of information on a ground surface (Bian et al, 2005, 2006; Champion & Warren, 2010; McCarley & He, 2000, 2001; Morita & Kumada, 2003), suggesting a unique role of the ground surface in the perceptual organization of 3D scenes.…”

“…McCarley and He (2000, 2001) found that visual search was faster on an implicit ground surface than on an implicit ceiling surface defined by binocular disparity. Their finding was extended by Morita and Kumada (2003) who showed superior visual search performance on a ground surface defined by pictorial cues. Champion and Warren (2010) also obtained an advantage of the ground surface as compared to the ceiling surface in 3D size estimation.…”

The present study examined whether the compression of perceived visual space varies according to the type of environmental surface being viewed. To examine this issue, observers made exocentric distance judgments when viewing simulated 3D scenes. In 4 experiments, observers viewed ground and ceiling surfaces and performed either an L-shaped matching task (Experiments 1, 3, and 4) or a bisection task (Experiment 2). Overall, we found considerable compression of perceived exocentric distance on both ground and ceiling surfaces. However, the perceived exocentric distance was less compressed on a ground surface than on a ceiling surface. In addition, this ground surface advantage did not vary systematically as a function of the distance in the scene. These results suggest that the perceived visual space when viewing a ground surface is less compressed than the perceived visual space when viewing a ceiling surface and that the perceived layout of a surface varies as a function of the type of the surface.

“…Thus, our finding of a more veridical space perception on the ground adds to those of previous studies that found the visual system has a preference to efficiently process ground over ceiling surfaces (Bian et al, 2005; 2006, 2011; Imura & Tomonaga, 2013; Kavšek & Granrud, 2013; McCarley& He, 2000; McCarley& He, 2001; Morita & Kumada, 2003). …”

The natural ground surface carries texture information that extends continuously from one’s feet to the horizon, providing a rich depth resource for accurately locating an object resting on it. Here, we showed that the ground surface’s role as a reference frame also aids in locating a target suspended in midair based on relative binocular disparity. Using real world setup in our experiments, we first found that a suspended target is more accurately localized when the ground surface is visible and the observer views the scene binocularly. In addition, the increased accuracy occurs only when the scene is viewed for 5 sec rather than 0.15 sec, suggesting that the binocular depth process takes time. Second, we found that manipulation of the configurations of the texture-gradient and/or linear-perspective cues on the visible ground surface affects the perceived distance of the suspended target in midair. Third, we found that a suspended target is more accurately localized against a ground texture surface than a ceiling texture surface. This suggests that our visual system usesthe ground surface as the preferred reference frame to scale the distance of a suspended target according to its relative binocular disparity.

“…The pile of cubes in Experiments 1-3 was designed to thwart such guidance. However, it is known that attention can be directed to a plane (He & Nakayama, 1995) (He & Nakayama, 1992) (Morita & Kumada, 2003) and it is known that attention spreads within surfaces (Egly, Driver, & Rafal, 1994). Figure 8 shows a set of cubes lying in a single plane.…”

In visual search, guidance by surface type is different than classic guidance

Visual search for targets among distractors is more efficient if attention can be guided to targets by attributes like color. In real-world search, we guide attention using information about surfaces. (e.g., paintings are on walls). We compare “classic” color guidance to surface guidance in “scenes” of cubes. When a target can lie on one of many surfaces, color guidance is effective but surface guidance is not (Exp. 1-3). Surface guidance works when cued surfaces are coplanar (Exp. 4) or few in number (Exp. 5). We speculate that surface guidance is slow and limited to very few surfaces at one time.
