概括

在户外导航期间的目光行为随着视力丧失而发生变化,形成从能见到到盲人个体的连续. 适应性策略,而不仅仅是视觉敏,塑造了这些移动模式.

科学领域:

眼科医生眼科眼科
人与计算机的交互
康复科学康复科学康复科学

背景情况:

对于失明或视力低下的人来说,户外导航是一个挑战.
视力障碍者在移动性方面的目光行为作用尚未得到充分研究.
有视力的个体使用一致的扫描,而视力受损的个体根据剩余的视力和经验进行适应.

研究的目的:

在不同视力群体的户外导航中比较分析眼神行为.
调查视力障碍如何影响移动性和眼睛跟踪指标.

主要方法:

进行了一项对比的眼睛追踪研究,对全视,低视,盲人和完全盲人参与者进行了比较.
参与者在佩戴可穿戴眼球追踪器时,在户外路线上导航.
量化的主要指标包括固定计数,速度,面积,方向,峰值固定位置和步行速度.

主要成果:

随着视力恶化,步行速度下降.
固定数量增加,空间覆盖率随着视力障碍的增加而下降.
凝视模式变得更加可变,并随着视力丧失的增加向外转移,与有视力的个体的集中模式不同.

结论:

导航期间的目光策略存在于基于视力水平的连续.
适应性策略和康复经验显著影响着眼睛的使用,而不仅仅是视力敏度.
研究结果支持个性化康复和辅助技术,使用目光模式来评估移动性,并指导为更安全的航行提供培训.

Visual Agnosia

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...
