Dual-Display AR Content Switching for Ambient Light Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable augmented reality (AR) devices face challenges in maintaining visibility of AR content due to changes in ambient illuminance, which can decrease the clarity of real objects displayed on the main display.
Innovation Solution
An electronic device that selects a target object based on user gaze direction and ambient illuminance, adjusting the display of AR content between a main and sub-display to optimize visibility, using a sensor module to measure illuminance and a processor to determine visibility levels, and displaying outlines and bounding boxes in high-visibility colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR content is displayed on the main display, then the user experience is immersive and integrated with the real view, but the visibility of AR content decreases when ambient illuminance increases
Solution Approach 1:
The patent divides the display system into two separate displays: a main display for showing real-world views and a sub-display for showing AR content. This segmentation allows the AR content to be displayed on a separate surface (such as the temple piece or earpiece) that is not directly affected by ambient illuminance changes, thereby maintaining visibility while preserving the immersive experience of the main display.
Solution Approach 2:
The sub-display acts as an intermediary carrier for AR content, transferring it from the main display area to a separate location. This intermediary approach allows the AR information to be presented in a location where visibility is less dependent on ambient lighting conditions, solving the contradiction between immersive display and visibility.
2Illumination intensity
If the electronic device displays only an outline and bounding box on the main display under high illuminance, then visibility of the target object is maintained, but complete AR content information is lost
Solution Approach 1:
The patent segments the AR content presentation into two parts: essential identification information (outline and bounding box) displayed on the main display for quick target recognition, and complete AR content information displayed on the sub-display for detailed viewing. This segmentation ensures that both visibility under high illuminance and information completeness are achieved simultaneously.
Solution Approach 2:
Different qualities of AR content presentation are applied to different displays: the main display provides high-visibility, simplified target identification suitable for high-illuminance conditions, while the sub-display provides comprehensive, detailed AR content. This local quality differentiation resolves the contradiction between visibility and information completeness.
3Illumination intensity
If AR content is displayed on the sub-display, then visibility is maintained under high illuminance, but the immersive experience and integration with real view is reduced
Solution Approach 1:
The patent segments the display functions to preserve immersion: the main display continues to provide the immersive real-world view without interruption, while the sub-display adds AR content in a non-intrusive manner. This segmentation allows the user to maintain the immersive experience while still accessing visible AR information when needed.
Solution Approach 2:
The patent merges the functionality of multiple displays into a unified AR system where the main display and sub-display work together. The main display provides immersion while the sub-display provides visibility, and their combined operation achieves both goals simultaneously, resolving the contradiction between immersion and visibility.

AI summary
An electronic device includes: a sensor module, a display module comprising a main display and a sub-display, a memory configured to store computer-executable instructions, and a processor configured to execute the instructions by accessing the memory, wherein the instructions, when executed by the processor, cause the processor to: identify at least one real object displayed through the main display, select one real object from among the identified at least one real object as a target object, control the sensor module to measure ambient illuminance of the electronic device, determine a visibility level of the electronic device based on the ambient illuminance of the electronic device, and display at least one augmented reality (AR) content corresponding to the selected target object on at least one of the main display or the sub-display based on the determined visibility level.
