People with photosensitive epilepsy may have seizures caused by flashing lights, patterns, and video sequences. Because of this, there is increasing interest among researchers, developers, and companies toward making content safer. There are five major guidelines (from the U.K., Japan, ISO, ITU, and W3C) to limit risk in different technology domains that have been created since the mid-1990s. All address similar risk factors, but they are not fully harmonized and can be confusing. Furthermore, there have been significant changes in technology since the guidelines were introduced. This article compares and clarifies the guidelines, describes risk factors that have changed (such as the reduction of risk due to display technology), gaps in our knowledge, the coverage of new technology, and new characteristics (such as the duration and synchronicity of individual flash transitions) that may need to be accounted for. The authors suggest working values for new thresholds and propose updated guidelines.
患有光敏性癫痫的人可能会因闪烁的灯光、图案和视频序列而引发癫痫发作。因此，研究人员、开发者和公司对使内容更安全的兴趣与日俱增。自20世纪90年代中期以来，已经制定了五条主要指南（来自英国、日本、国际标准化组织、国际电信联盟和万维网联盟），以限制不同技术领域的风险。所有指南都涉及类似的风险因素，但它们并未完全统一，可能会令人困惑。此外，自指南推出以来，技术发生了重大变化。本文对这些指南进行了比较和澄清，描述了已发生变化的风险因素（如显示技术导致的风险降低）、我们知识上的空白、新技术的覆盖范围以及可能需要考虑的新特性（如单个闪光过渡的持续时间和同步性）。作者提出了新阈值的工作值，并建议更新指南。
