Dynamic Color Temperature Adjustment for Sleep Cycle Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers experience disrupted sleep and wake states due to excessive blue light exposure from video content, particularly when viewed at inappropriate times, leading to difficulties in falling asleep and reduced productivity.
Innovation Solution
A method that dynamically shifts the color of video content pixels based on the time of day, increasing red light and decreasing blue light when it is near the viewer's sleep time and vice versa, using algorithms that adjust color values for display screens to mimic natural light patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If blue spectrum light is provided to viewers late at night, then the viewer can see video content clearly, but the viewer experiences difficulty falling asleep and restless sleep
Solution Approach 1:
The patent applies dynamics by making the color temperature of the display adaptive rather than fixed. The system dynamically adjusts the color temperature based on the time of day, transitioning from cooler tones during daytime to warmer tones in the evening. This dynamic adjustment allows the display to maintain visibility while reducing blue light exposure during sleep hours, thereby resolving the contradiction between clear viewing and sleep disruption.
Solution Approach 2:
The patent changes the color temperature parameter of the display output based on temporal conditions. By modifying the color temperature parameter from standard daylight balance to warmer tones during evening hours, the system maintains adequate visibility while shifting the spectral composition to reduce blue light exposure, thus addressing both visibility requirements and sleep disruption concerns.
2Object-affected harmful factors
If red spectrum light is provided to viewers during the middle of the day, then the viewer may feel more relaxed, but the viewer becomes less productive and drowsy
Solution Approach 1:
The system dynamically adjusts color temperature based on the time of day, applying cooler tones during daytime hours to maintain alertness and productivity, and transitioning to warmer tones only during evening hours when productivity decreases naturally. This dynamic approach prevents the drowsiness associated with red spectrum exposure during daytime while still providing eye strain reduction benefits when needed.
Solution Approach 2:
The patent implements periodic action by cycling through different color temperature profiles based on the daily light-dark cycle. The system alternates between cooler and warmer color temperatures in a periodic manner that aligns with natural circadian rhythms, providing alertness during daytime periods and relaxation during evening periods without causing drowsiness during productive hours.
3Stability of the object's composition
If the display uses standard color temperature throughout the day, then the display performance is consistent, but the viewer's circadian rhythms are disrupted
Solution Approach 1:
The system transitions from a static color temperature setting to a dynamic one that adapts to the time of day. By making color temperature a variable parameter that changes based on temporal conditions, the system maintains display performance consistency during daytime while adjusting to protect circadian rhythms during evening hours, thus resolving the contradiction between consistency and biological impact.
Solution Approach 2:
The patent changes the color temperature parameter based on temporal conditions while maintaining overall display performance. The system adjusts this single critical parameter to balance between maintaining consistent display quality and protecting circadian rhythms, achieving both goals through coordinated parameter modification.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach helps regulate the viewer's circadian rhythms, promoting restful sleep and enhanced wakefulness by aligning screen light with natural light cues, thereby improving sleep quality and daytime alertness.
Implementation Method 1
displaying the frame of video data with the color shifted pixels to the user, based on the time of day when the frame of video data is to be displayed on the display screen, as compared to a time of day when the user is predicted to go to sleep or to awake from sleep
Data Source
AI summary
Methods are disclosed for receiving and processing video content to aid in a user's rest cycles, such as sleep and wake cycles. Video content may be received and processed to determine information related to a plurality of pixels to be displayed on a screen. Each of the plurality of pixels may have a corresponding color value. A time of day when the video content is to be displayed is determined, and compared to a current time of day. Based on the comparison or other data, a color value of one or more of the pixels can be adjusted or changed.
