Monocular ER Display Parameter Tuning to Prevent Binocular Rivalry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality (ER) systems face challenges in optimizing virtual stimulus display when operating in monocular mode, leading to user discomfort such as binocular rivalry, eyestrain, and nausea, due to differences in how the human visual system processes monocular and binocular content.
Innovation Solution
The system determines its operating mode and applies customized monocular display parameters, including location, contrast, introduction velocity, display resolution, field of view, and focal plane adjustments to optimize virtual stimulus display on a single display, thereby avoiding binocular rivalry and enhancing user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual stimulus is displayed on both displays in binocular mode, then immersion and realism are improved, but user comfort deteriorates due to binocular rivalry and eyestrain when operating in monocular mode
Solution Approach 1:
The system dynamically switches between binocular and monocular display modes based on user needs or operational conditions. When operating in monocular mode, the system automatically adjusts display parameters to optimize virtual stimulus presentation on a single display, preventing binocular rivalry and eyestrain while maintaining immersion and realism through adaptive parameter modification
2Ease of operation
If monocular display parameters are not optimized, then device complexity is reduced, but user experience deteriorates due to binocular rivalry and suppression of virtual content
Solution Approach 1:
The system modifies multiple display parameters including location, contrast, introduction velocity, display resolution, field of view, and focal plane to optimize virtual stimulus presentation in monocular mode. These parameter adjustments ensure the virtual content is visible and attention-grabbing without suppression by the user's brain, while the system automatically manages the complexity of coordinating these parameter changes
3Illumination intensity
If virtual stimulus is displayed with standard parameters on one display, then display simplicity is maintained, but visibility and attention-grabbing capability are reduced due to lack of optimization
Solution Approach 1:
The system applies different display parameters specifically optimized for monocular viewing conditions to the single active display. This includes adjusting location, contrast, introduction velocity, display resolution, field of view, and focal plane to ensure the virtual stimulus is optimally visible and attention-grabbing on the one display that is active, rather than using uniform standard parameters
Data Source
AI summary
A service configures a monocular display parameter associated with a virtual stimulus to achieve optimized viewing of the virtual stimulus on only one display of an ER system. The service determines that the ER system is operating in a monocular mode. The service accesses the monocular display parameter that is associated with the virtual stimulus. The monocular display parameter is applicable when the ER system is operating in the monocular mode. In response to determining that the ER system is operating in the monocular mode, the service causes the virtual stimulus to be displayed on only the one display. Beneficially, the virtual stimulus is displayed using the monocular display parameter.
