概括

视觉运动检测值可以在站立和走路时可靠地测量. 这些对于平衡控制至关重要的值在行走时明显高于站立时.

科学领域:

人类的感觉运动控制
感知和心理物理学的认识.
生物力学和机动力学

背景情况:

直立平衡依赖于整合视觉,前体和体感官线索.
虽然前体和体感官与平衡的联系已知,但视觉运动检测对直立平衡控制的影响需要进一步调查.
目前用于测量视觉运动值的方法通常发生在坐着,头部固定的条件下,限制了生态有效性.

研究的目的:

为了确定视觉运动检测值是否可以在站立和走路等动态活动中可靠地测量.
调查这些值是否在站立和走路条件之间有所不同.
在存在自动运动的情况下,评估这些测量的可靠性和一致性.

主要方法:

29名参与者在虚拟现实环境中的仪器跑步机上执行了视觉运动区分任务.
一个自适应式楼梯算法呈现了旋转的视觉场景,以估计检测值.
对二进制反应进行了心理测量功能,以量化视觉运动检测值在自动站立和步行过程中.

主要成果:

在站立和走路时,可实现可靠和可重复的视觉运动检测值测量.
在两种条件下重复测量之间观察到强烈的相关性 (站立R=0.73,走路R=0.84).
平均视觉运动检测值在走路时 (1.04°) 与站立 (0.73°) 相比显著更高.

结论:

视觉运动检测值在直立和行走时可靠地测量,即使是自然自动运动.
这些发现表明,较高的视觉运动检测值与行走有关.
这表明动态运动会影响与平衡控制相关的视觉运动感知值.

Difference from Background: Limit of Detection

Difference from Background: Limit of Detection

The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

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.
