Abstract

The purpose of this study was to investigate the effect of stereoscopic display alignment errors on visual fatigue and prefrontal cortical tissue hemodynamic responses. We collected hemodynamic data and perceptual ratings of visual fatigue while participants performed visual display tasks on 8 ft × 6 ft NEC LT silver screen with NEC LT 245 DLP projectors. There was statistical significant difference between subjective measures of visual fatigue before air traffic control task (BATC) and after air traffic control task (ATC 3), (P < 0.05). Statistical significance was observed between left dorsolateral prefrontal cortex oxygenated hemoglobin (l DLPFC-HbO2), left dorsolateral prefrontal cortex deoxygenated hemoglobin (l DLPFC-Hbb), and right dorsolateral prefrontal cortex deoxygenated hemoglobin (r DLPFC-Hbb) on stereoscopic alignment errors (P < 0.05). Thus, cortical tissue oxygenation requirement in the left hemisphere indicates that the effect of visual fatigue is more pronounced in the left dorsolateral prefrontal cortex.

摘要

本研究的目的是调查立体显示校准误差对视觉疲劳和前额叶皮质组织血流动力学反应的影响。我们收集了血流动力学数据以及视觉疲劳的感知评分，在此期间参与者使用NEC LT 245 DLP投影仪在8英尺×6英尺的NEC LT银屏上执行视觉显示任务。空中交通管制任务前（BATC）和空中交通管制任务后（ATC 3）的视觉疲劳主观测量之间存在统计学显著差异（P < 0.05）。在立体校准误差方面，观察到左背外侧前额叶皮质氧合血红蛋白（l DLPFC-HbO2）、左背外侧前额叶皮质脱氧血红蛋白（l DLPFC-Hbb）和右背外侧前额叶皮质脱氧血红蛋白（r DLPFC-Hbb）之间存在统计学显著性（P < 0.05）。因此，左半球皮质组织的氧合需求表明，视觉疲劳的影响在左背外侧前额叶皮质更为明显。
