项目摘要

We examined how human beings achieve visual stability during body movements, including fine motion, on the ground. The perception of visual stability is modified by other sensations such as somatosensory, vestibular, and muscle tension. We will mainly focus on modifications of visual perception produced by eye movements in microgravity due to vestibular inputs. The VOR is constantly stimulated under 1-G conditions here on Earth. In fact, human beings have been habituated and "programd" for orientation (visual stability) in their everyday, 1-G environment. When humans are exposed to an environment with different gravity vectors, this programd behavior must change ; that is, it is reprogramd. This is called habituation or familiarization. We examined how object motion perception is perturbed in the microgravity environment. The experiment focuses on visual, vestibular and somatosensory perception coordination and how it changes in microgravity as compared to a 1-G environment. We obtained information on the coordination between eye movement and neck muscle activity using EOG and EMG.We also collected data from the payload specialist by a self-diagnostic questionnaire concerned with perceptual abnormality. When each sensory input function and it's integration the higher nervous system are well characterized, more effective techniques to control SAS may be developed. The subject was one of the co-authors in the current research report, Japanese payload specialist(JPS) Mamoru Mohri.

我们研究了人类在地面上的身体运动（包括精细运动）中如何实现视觉稳定。视觉稳定性的感知被其他感觉如躯体感觉、前庭和肌肉紧张所改变。我们将主要关注微重力条件下前庭输入引起的眼球运动对视觉感知的影响。VOR在地球上的1-G条件下不断受到刺激。事实上，人类已经习惯于在日常的1G环境中进行定向（视觉稳定性）。当人类暴露在一个具有不同重力矢量的环境中时，这种编程行为必须改变;也就是说，它被重新编程。这被称为习惯化或熟悉化。我们研究了在微重力环境中物体运动感知是如何受到干扰的。该实验的重点是视觉，前庭和体感感知协调以及与1-G环境相比，微重力下的变化。我们获得的眼动和颈部肌肉活动之间的协调，使用EOG和EMG的信息。我们还收集了数据，从负载专家的自我诊断问卷有关的知觉异常。当每个感觉输入功能和它的整合高级神经系统的特点，更有效的技术来控制SAS可能会发展。该主题是当前研究报告的共同作者之一，日本有效载荷专家（JPS）Mamoru Mohri。
