概括

环境亮度不会影响视觉指导的saccades的眼球跟踪精度. 一个新的人工眼睛 (RELAY) 显示,观察到的变化可能是由于人为因素,而不是眼睛追踪器本身.

科学领域:

眼科医生眼科眼科
神经科学是一个神经科学.
生物医学工程生物医学工程

背景情况:

在眼睛跟踪研究中,环境照明对视觉引导的冲峰值速度的影响受到争论.
以前的发现是不一致的,可能是由于瞳孔变形,凝视位置或测量工件.

研究的目的:

用受控的人工眼研究环境亮度对冲峰速度的影响.
为了评估 EyeLink 1000 眼球追踪器在不同照明设置中的可靠性.

主要方法:

研发RELAY (机器人眼链分析),这是一款模拟人类跳动的人工眼睛,具有可控参数.
使用EyeLink 1000眼球追踪器在不同的光线条件下测量准确度和精度.
系统评估与视线方向的瞳孔大小变化的系统评估.

主要成果:

EyeLink 1000表现出可靠的性能,在以瞳孔为基础的眼睛跟踪中没有与亮度相关的工件.
在不同研究中观察到的冲速度差异很可能归因于人为因素,而不是照明.
根据凝视方向,测量学生尺寸的系统偏差被记录在内.

结论:

环境亮度本身不会影响基于瞳孔的眼睛跟踪的准确性.
人类因素,而不是照明,很可能解释了之前在冲击速度测量中的差异.
报告照明和目光参数对于一致和可比的眼睛跟踪数据至关重要.

关键词:

Muscles of the Eye

Muscles of the Eye

The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...
