Although head-mounted displays (HMDs) are ideal devices for personal viewing of immersive stereoscopic content, exposure to VR applications on them results in significant discomfort for the majority of people, with symptoms including eye fatigue, headaches, nausea, and sweating. A conflict between accommodation and vergence depth cues on stereoscopic displays is a significant cause of visual discomfort. This article describes the results of an evaluation used to judge the effectiveness of dynamic depth-of-field (DoF) blur in an effort to reduce discomfort caused by exposure to stereoscopic content on HMDs. Using a commercial game engine implementation, study participants report a reduction of visual discomfort on a simulator sickness questionnaire when DoF blurring is enabled. The study participants reported a decrease in symptom severity caused by HMD exposure, indicating that dynamic DoF can effectively reduce visual discomfort.
尽管头戴式显示器（HMD）是个人观看沉浸式立体内容的理想设备，但在其上接触虚拟现实（VR）应用程序会让大多数人感到极度不适，症状包括眼睛疲劳、头痛、恶心和出汗。立体显示器上调节和聚散深度线索之间的冲突是视觉不适的一个重要原因。本文描述了一项评估结果，该评估旨在判断动态景深（DoF）模糊在减少因接触HMD上的立体内容而引起的不适方面的有效性。通过商业游戏引擎实现，研究参与者报告称，启用DoF模糊后，在模拟器晕动症问卷上视觉不适有所减轻。研究参与者报告说，HMD暴露引起的症状严重程度有所降低，这表明动态DoF可以有效减少视觉不适。
