概括
单眼和双眼深度线索仅在一致时才用于大小感知. 当冲突时,单眼线索主导了尺寸判断,特别是在虚拟现实中.
科学领域:
- 视觉感知 视觉感知 视觉感知
- 计算神经科学是一种计算神经科学.
- 人与计算机的互动.
背景情况:
- 三维 (3D) 深度感知对于准确的大小估计至关重要.
- 视觉系统整合了双眼和单眼深度线索.
- 对于3D尺寸计算的这些线索之间的相互作用仍然不太了解.
研究的目的:
- 为了研究单眼和双眼深度信息在尺寸感知中的相互作用.
- 在一致和不一致的条件下确定每个提示类型的相对贡献.
- 在虚拟现实 (VR) 环境中使用修改后的庞佐幻象来检查这些相互作用.
主要方法:
- 在虚拟现实环境中实现了经过修改的Ponzo幻觉.
- 参与者在单眼和双眼深度线索一致或不一致的条件下判断物体大小.
- 在两个条件之间比较了尺寸错觉的规模.
主要成果:

Depth Perception and Spatial Vision
751
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Perceptual Constancy
458
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
