VR Display Spectral Mapping for Eyestrain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual and augmented reality systems cause eyestrain due to incorrect monitor settings, harsh bright colors, and lack of effective solutions for color blindness, with existing technologies failing to provide a comprehensive solution for all users.
Innovation Solution
An apparatus and method that modify display settings by using spectral mappings to adjust color attributes, such as hue, saturation, and luminosity, based on user selection, biometric feedback, and application metadata, allowing for personalized color correction and mitigation of eyestrain through a shader in the processing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If harsh bright colors are used in VR/AR displays, then visual impact and application effectiveness are improved, but user comfort deteriorates due to eyestrain and discomfort
Solution Approach 1:
The system dynamically adjusts display parameters including brightness, contrast, and color temperature based on real-time user feedback and environmental conditions. The display settings are not fixed but adapt continuously to optimize both visual impact and user comfort, resolving the contradiction between harsh bright colors and eye strain.
Solution Approach 2:
The patent changes multiple display parameters simultaneously (brightness, contrast, color temperature, saturation) to achieve optimal visual experience. By adjusting these parameters based on user needs and environmental factors, the system maintains effective visual display while reducing harmful effects on user comfort.
2Adaptability or versatility
If standard display settings are used for all users, then device complexity is reduced, but adaptability deteriorates because different users have different visual needs and color blindness conditions
Solution Approach 1:
The system automatically adjusts display settings based on user feedback, environmental sensors, and pre-configured user profiles. Users don't need to manually configure complex parameters - the system serves itself by detecting user needs and applying appropriate adjustments, thereby achieving high adaptability without increasing operational complexity for users.
Solution Approach 2:
The system incorporates feedback mechanisms to detect user visual responses and environmental conditions, then automatically adjusts display parameters accordingly. This closed-loop approach enables personalized adaptation for different users and conditions while keeping the interface simple, as the system learns and adjusts based on observed feedback.
3Object-affected harmful factors
If spectral mapping adjustments are applied to reduce eyestrain, then user comfort is improved, but color accuracy may deteriorate
Solution Approach 1:
The spectral mapping adjustments are applied selectively to specific wavelength ranges that cause eye strain (e.g., reducing blue light content) while preserving color accuracy in other ranges. Different portions of the spectrum are treated differently - some are adjusted for comfort, others maintained for accuracy, resolving the contradiction between comfort improvement and color fidelity.
Data Source
AI summary
An apparatus that modifies display settings of image data is provided. The apparatus stores one or more spectral mappings and receives display data for an image. The received display data includes a plurality of colors and each of the colors includes a plurality of attributes. A spectral mapping, of the one or more spectral mappings, is identified based on a detected user visual limitation. Each of the spectral mappings maps a set of spectral colors to an adjusted set of spectral colors and provides attribute adjustments for the set of spectral colors of image data so an image can be displayed in a manner that mitigates the user's visual limitation. The mapped and adjusted plurality of colors of the image data that mitigate the visual limitation when displayed on a display may mitigate, for example, viewer color blindness, eye strain, biometric measurements and/or other visual limitations.
