The Images in an immersive head‐mounted display (HMD) for virtual reality provide the sole source for visual adaptation. Thus, significant, near‐instantaneous increases in luminance while viewing an HMD can result in visual discomfort. Therefore, the current study investigated the luminance change necessary to induce this discomfort. Based on the psychophysical experiment data collected from 10 subjects, a prediction model was derived using four complex images and one neutral image, with four to six levels of average scene luminance. Result showed that maximum area luminance has a significant correlation with the discomfort luminance level than average, median, or maximum pixel luminance. According to the prediction model, the discomfort luminance level of a head‐mounted display was represented as a positive linear function in log₁₀ units using the previous adaptation luminance when luminance is calculated as maximum area luminance.

头戴式显示器的不舒适亮度等级取决于适应的亮度

用于虚拟现实的沉浸式头戴式显示器（HMD）中的图像提供了视觉适应的唯一来源。因此，在观看HMD时，亮度的显着增加几乎会瞬时导致视觉不适。因此，当前的研究调查了引起这种不适所需的亮度变化。根据从10位受试者收集的心理物理实验数据，使用四张复杂图像和一张中性图像（平均场景亮度为四到六级）导出了预测模型。结果表明，最大区域亮度与不舒适亮度水平相比，平均，中值或最大像素亮度具有显着的相关性。根据预测模型，头戴式显示器的不适亮度级别以对数形式为正线性函数表示当计算亮度为最大区域亮度时，使用先前的适应亮度_10个单位。
