The human ability for visualization extends far beyond the physical items that surround us. We are able to dismiss the constant influx of photons hitting our retinas, and instead picture the layout of our kindergarten classroom, envision the gently swaying palm trees of our dream vacation, or foresee the face of a yet-to-be-born child. As we inspect imaginary objects and people with our mind's eye, our corporeal eyeballs latch onto the fantasy. Research has found that our eyes can move as if seeing, even when there is nothing to look at. Thus, gaze explorations in the absence of actual vision have been reported in many contexts, including in visualization and memory tasks, and perhaps even during REM sleep. This symposium will present the manifold aspects of gaze dynamics in conditions when the visual input is impoverished or altogether absent. Presentations will address the characteristics of large and small eye movements during imagined and remembered scenes, the impact of visual field deficits on oculomotor control, and the role of eye movements in the future development of neural prosthetics for the blind. https://vimeo.com/365522806.
人类的视觉化能力远远超出了我们周围的实体物品。我们能够忽略不断涌入视网膜的光子，转而想象幼儿园教室的布局，设想梦幻假期中轻轻摇曳的棕榈树，或者预见未出生孩子的面容。当我们用心灵之眼审视想象中的物体和人物时，我们的肉体眼球会锁定在幻想上。研究发现，即使没有任何东西可看，我们的眼睛也能像在看东西一样移动。因此，在许多情况下都报告了在没有实际视觉时的注视探索，包括在视觉化和记忆任务中，甚至可能在快速眼动睡眠期间。本次研讨会将展示在视觉输入匮乏或完全缺失的情况下注视动态的多个方面。演讲将探讨在想象和记忆场景中大小眼动的特征、视野缺陷对眼球运动控制的影响，以及眼动在盲人神经假体未来发展中的作用。https://vimeo.com/365522806。
