Dynamic visual acuity under the influence of a somatosensory input

针对动态视敏度（DVA），提出了一种基于客观量化的DVA评价方法，该方法排除了预测值和目标清晰度的主观性。用这种方法，阐明了运动员与非运动员DVA差异的生理机制。比较运动员和非运动员的数据支持DVA反映了“将眼睛适当地转向移动目标的能力”，而不是“感知视网膜图像的能力”。此外，还研究了颈肌梭体感输入对DVA的影响。本研究的结果表明，DVA涉及允许体感输入的因素。结果表明，目标的运动方向与物体的运动方向密切相关。

About dynamic visual acuity (DVA), a method for DVA evaluation based on its objective quantification which excludes a prediction and the subjectivity of legibility for the target was proposed. Using this method, the physiologic mechanism of differences in the DVA between athletes and nonathletes was clarified. Data comparing athletes and nonathletes support the DVA reflects "the ability to turn the eyes appropriately to moving targets" rather than "the ability to perceive retinal images". Furthermore, DVA affected by the somatosensory input of cervical muscle spindle was investigated. The results of this study suggest that DVA involve factors that allow the somatosensory input. And it was shown that the move direction of targets and direction of the body are closely related.
