主要方法:

参与者被动地探索以PC,VR和RL模式呈现的抽象对象.
一个使用延迟匹配到样本任务的活跃探索阶段接下来是被动查看.
记录了电生理学反应 (ERP,α频段),以分析视觉处理.

主要成果:

所有模式都引起了相似的基本视觉过程.
现实生活 (RL) 视觉处理显示ERP响应 (P1-N1-P2复合体) 幅度与VR相似,并且大于PC.
立体镜影响了早期处理 (P1,N1),而P2差异表明了潜在的VR诱导的视觉疲劳. 阿尔法频段分析表明,与RL相比,PC和VR的注意力要求更高.

Vision

Vision

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Parallel Processing

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

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.
