Online video platforms have enabled unprecedented access to diverse content, but minors and other vulnerable viewers can also be exposed to highly graphic or violent materials. This study addresses the need for a nuanced method of filtering gore by developing a segmentation-based approach that selectively blurs blood. We recruited 37 participants to watch both blurred and unblurred versions of five gory video clips. Eye-based physiological and gaze data, including eye openness ratio, blink frequency, and eye fixations, were recorded via a webcam and eye tracker. Our results demonstrate that partial blood blurring substantially lowers perceived gore in more brutal scenes. Additionally, participants exhibited distinctive physiological reactions when viewing clips with higher gore, such as decreased eye openness and more frequent blinking. Notably, individuals with a stronger fear of blood showed an even greater tendency to blink, suggesting that personal sensitivities shape responses to graphic content. These findings highlight the potential of segmentation-based blurring as a balanced content moderation strategy, reducing distress without fully eliminating narrative details. By allowing users to remain informed while minimizing discomfort, this approach could prove valuable for video streaming services seeking to accommodate diverse viewer preferences and safeguard vulnerable audiences.
在线视频平台使人们能够前所未有的接触到各种各样的内容，但未成年人和其他易受影响的观众也可能接触到高度血腥或暴力的材料。本研究通过开发一种基于分割的方法来选择性地模糊血液，满足了对一种细致入微的血腥过滤方法的需求。我们招募了37名参与者观看五个血腥视频片段的模糊和未模糊版本。通过网络摄像头和眼动仪记录基于眼睛的生理和注视数据，包括睁眼率、眨眼频率和眼睛注视。我们的结果表明，在更血腥的场景中，部分血液模糊会显著降低感知到的血腥程度。此外，参与者在观看血腥程度较高的片段时表现出独特的生理反应，如睁眼减少和眨眼更频繁。值得注意的是，对血液恐惧较强的个体眨眼的倾向甚至更大，这表明个人敏感度会影响对血腥内容的反应。这些发现凸显了基于分割的模糊处理作为一种平衡的内容审核策略的潜力，既能减少困扰又不会完全消除叙事细节。通过让用户在尽量减少不适的同时保持知情，这种方法对于寻求满足不同观众偏好并保护易受影响观众的视频流服务可能具有重要价值。
