Solution Overview
Problem
Existing AR content display technologies do not adequately address issues such as binocular rivalry, safety, and integration with physical surroundings, leading to suboptimal user experiences.
Innovation Solution
Optimizing the display location of AR content within AR glasses by considering factors like binocular rivalry, safety, and user fitment, using a method that determines an optimized display location based on physical surroundings and safety criteria, and adjusts the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AR content is displayed at conventional locations in AR glasses, then the display is visible to the user, but it causes binocular rivalry and eye strain
Solution Approach 1:
The patent applies local quality by displaying AR content in the peripheral vision area rather than the central foveal region. This localized display approach places content in the temporal periphery where it does not interfere with central binocular fusion, thereby reducing binocular rivalry while maintaining visibility. The display location is specifically chosen to exploit the different functional characteristics of peripheral versus central vision.
Solution Approach 2:
The patent transitions the display location from the central horizontal meridian to the temporal peripheral region, effectively moving the content to a different spatial dimension in the visual field. This dimensional shift allows the AR content to be perceived without competing with the central binocular input that is essential for depth perception and fusion.
2Ease of operation
If AR content is displayed at optimized locations, then user comfort is improved, but safety requirements may be compromised
Solution Approach 1:
The patent implements dynamic adjustment of display parameters based on real-time detection of user state and environment. The system continuously monitors safety conditions and dynamically modifies display characteristics such as brightness, contrast, and content priority to ensure safety is maintained while optimizing comfort. This dynamic adaptation allows the system to balance comfort optimization with safety requirements under varying conditions.
Solution Approach 2:
The patent incorporates feedback mechanisms that monitor user behavior, environmental context, and safety conditions to adjust display parameters. The system uses feedback from sensors and user interactions to continuously optimize display location and characteristics while ensuring safety constraints are met, allowing comfort to be improved without compromising safety.
3Loss of information
If AR content is displayed to enhance visibility, then content can be seen, but it reduces awareness of physical surroundings
Solution Approach 1:
The patent segments the visual field into distinct functional zones: central vision for awareness of physical surroundings and peripheral vision for AR content display. By separating these functions spatially, the system allows users to maintain situational awareness through central vision while receiving AR information in the periphery, thereby reducing the loss of situational awareness that would result from centralized display.

AI summary
An example method of optimizing a display location for displaying augmented-reality (AR) content is provided. The method includes operations performed at an AR device having a lens display for displaying the AR content. The method includes determining, based on imaging data obtained about physical surroundings of the AR glasses, whether to present the AR content at an optimized display location of the lens of the AR device. The optimized display location is determined based on: (i) minimizing an occlusion factor, (ii) increasing depth-switching demands of the user, (iii) minimizing eye strain of the user, and (iv) optimizing an eyebox position of the AR content such that the amount of AR content subject to display clipping based on fitment factors of individual users is minimized. The method includes, when determining the physical surroundings satisfy one or more viewing criteria, causing display of the AR content at the optimized display location.
