Monocular ER Display Parameter Tuning to Reduce 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 tailored 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
1Adaptability or versatility
If the ER system displays virtual stimulus on a single display in monocular mode, then the system can operate in flexible modes and adapt to user needs, but user discomfort such as binocular rivalry, eyestrain, and nausea occurs due to differences in visual processing
Solution Approach 1:
The system dynamically adjusts multiple display parameters including location, contrast, introduction velocity, display resolution, field of view, and focal plane when operating in monocular mode. These parameter changes optimize the virtual stimulus presentation to align with monocular visual processing characteristics, thereby reducing user discomfort while maintaining adaptability
2Ease of operation
If conventional display parameters are used in monocular mode, then the system maintains simplicity in operation, but the virtual stimulus display is not optimized leading to reduced user comfort and engagement
Solution Approach 1:
The system automatically detects whether it is operating in monocular or binocular mode and dynamically adjusts display parameters accordingly. This dynamic adaptation occurs without user intervention, maintaining ease of operation while optimizing virtual stimulus presentation for the current mode to enhance user comfort and engagement
3Device complexity
If the virtual stimulus is displayed with standard parameters on one display, then the system structure remains simple, but the perception of virtual content is not optimized causing reduced clarity and engagement
Solution Approach 1:
The system adjusts multiple display parameters including location, contrast, introduction velocity, display resolution, field of view, and focal plane to optimize virtual content perception. These parameter modifications are applied software-based, maintaining simple hardware structure while significantly improving the quality and clarity of virtual stimulus presentation

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.
