Stereoscopic AR Head-worn Display with Conformal Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-worn displays lack the ability to effectively integrate augmented reality features that provide accurate, stereoscopic, and adjustable depth indicators in real-world environments, particularly in low visibility situations, which can hinder pilots' ability to navigate and operate aircraft safely.
Innovation Solution
A head-worn display system equipped with processors that determine its location relative to the real-world environment, generating conformal and non-conformal indicators, and a stereoscopic display that presents these indicators at appropriate depths to enhance the user's understanding of their surroundings, including virtual panels and alerts, while allowing adjustable depth settings to reduce clutter and draw attention to critical information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If head-worn displays present multiple augmented reality indicators in the field of view, then information provision is improved, but visual clutter increases and reduces clarity
Solution Approach 1:
The patent applies local quality by differentiating between conformal indicators (which conform to real-world elements and appear at their actual depth) and non-conformal indicators (which do not conform and appear at adjustable depths). This allows different types of information to be presented with different visual characteristics, reducing overall clutter while maintaining information completeness.
Solution Approach 2:
The patent utilizes the depth dimension in stereoscopic display to organize information hierarchically. Critical information can be placed at different depth planes, allowing users to focus on important elements while less critical information resides in the background, effectively reducing visual clutter without losing information.
2Reliability
If head-worn displays provide fixed depth indicators, then stereoscopic visualization is improved, but adaptability to different user needs deteriorates
Solution Approach 1:
The patent implements dynamics by making the depth of non-conformal indicators adjustable rather than fixed. Users can modify the stereoscopic depth of various indicators according to their specific needs and preferences, allowing the system to adapt to different users and situations while maintaining reliable stereoscopic visualization.
3Device complexity
If head-worn displays present all information at the same depth, then device simplicity is improved, but situational awareness and safety deteriorate
Solution Approach 1:
The patent leverages the depth dimension to enhance situational awareness without significantly increasing device complexity. By presenting critical safety information at different depth planes than background information, the system naturally guides user attention to important elements, improving situational awareness while maintaining relatively simple display configuration.

AI summary
Head-worn displays are disclosed. A head-worn display may include at least one processor configured to determine a location of the head-worn display with respect to a real-world environment and to generate a conformal indicator conforming to an element in the real-world environment. The at least one processor may also be configured to generate a non-conformal indicator unconstrained by elements in the real-world environment. The head-worn display may include at least one display in communication with the at least one processor. The at least one display may be configured to display the conformal indicator and/or the non-conformal indicator generated by the at least one processor to a user.
