在虚拟环境中，通过头戴式显示器（HMD），自我中心的距离往往被低估。以往的研究表明，周边视觉可以影响距离知觉。具体地，外围中的光可以改善HMD中的距离判断。在这项研究中，我们进行了一系列的实验与不同的周边处理周围的视口。首先，我们发现当周边亮度超过某个阈值时，周边亮度会显著影响距离判断，并找到了阈值的可能范围。其次，我们通过改变外周治疗的大小来扩展我们以前的研究。更大的视野（HMD的视野）导致与我们使用黑色周边处理的原始实验相比显著更准确的距离判断。最后，我们发现，应用像素化周边处理也可以提高距离判断。结果表明，辅助低分辨率显示器增强周边视觉可能会改善HMD的距离判断。
Egocentric distances are often underestimated in virtual environments through head-mounted displays (HMDs). Previous studies suggest that peripheral vision can influence distance perception. Specifically, light in the periphery may improve distance judgments in HMDs. In this study, we conducted a series of experiments with varied peripheral treatments around the viewport. First, we found that the peripheral brightness significantly influences distance judgments when the periphery is brighter than a certain threshold, and found a possible range where the threshold was in. Second, we extended our previous research by changing the size of the peripheral treatment. A larger visual field (field of view of the HMD) resulted in significantly more accurate distance judgments compared to our original experiments with black peripheral treatment. Last, we found that applying a pixelated peripheral treatment can also improve distance judgments. The result implies that augmenting peripheral vision with secondary low-resolution displays may improve distance judgments in HMDs.
