Computing Device Playback Control for Fast-Playback Seizure Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exposure to flashing lights or certain audio patterns can trigger seizures or exacerbate conditions like Photosensitive Epilepsy, anxiety, PTSD, headaches, or migraines, especially when content is displayed at fast playback speeds.
Innovation Solution
Computing devices analyze content for potentially harmful visual or audio patterns and modify characteristics such as brightness or volume to mitigate their impact on individuals with these conditions, preventing display or playback at harmful speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If content is displayed at fast playback speed, then productivity is improved, but object-affected harmful factors worsen
Solution Approach 1:
The system performs preliminary analysis of content to identify potentially harmful patterns (flashing lights, certain audio frequencies) before playback. Metadata is pre-generated indicating hazardous segments, allowing the system to proactively prevent harmful playback by blocking fast-forward through identified segments or notifying users before playback begins
Solution Approach 2:
The system introduces an intermediary layer between the content source and the display device. This intermediary analyzes content metadata, determines harmful patterns, and controls playback behavior by blocking fast-forward commands or adjusting playback parameters, thereby mediating between user productivity needs and safety concerns
2Object-affected harmful factors
If brightness is reduced to mitigate flashing lights, then object-affected harmful factors are reduced, but illumination intensity worsens
Solution Approach 1:
The system applies local quality modification by selectively reducing brightness only in specific regions or time segments where harmful flashing patterns are detected, rather than uniformly dimming the entire display. This allows maintaining overall visibility while locally mitigating seizure-triggering patterns
Solution Approach 2:
The system dynamically changes display parameters (brightness, contrast, saturation) based on real-time analysis of content patterns. When harmful flashing is detected, the system adjusts these parameters to reduce the intensity of problematic visual elements while preserving the overall viewing experience

AI summary
Methods and systems are described for condition mitigation. A computing device may display content. The computing device may determine that displaying and/or outputting the content may impact a person with a condition. The computing device may take an action to reduce an impact of the content on the person.
