Wearable AR Display Control for Moving Window Viewports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices struggle to seamlessly display virtual content when the external display, such as a window or sunroof, moves, causing disruptions in the user's experience.
Innovation Solution
A wearable electronic device equipped with a camera, display, and processor that identifies a displayable area corresponding to an external display, and upon detecting movement, divides the area into a first area where the external display is present and a second area where it is not, allowing the device to display a virtual screen on the second area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable electronic device displays virtual content tied to a specific external display area, then the user experience is immersive and context-aware, but the display becomes interrupted or lost when the external display moves
Solution Approach 1:
The patent implements dynamic area monitoring by continuously tracking the position and state of external displays (windows, sunroofs) rather than treating them as static. The system updates the displayable area information in real-time based on camera feedback and sensor data, allowing the virtual content to adapt its position and maintain visibility even as the external display moves during vehicle operation.
Solution Approach 2:
The system employs feedback mechanisms through cameras and sensors that continuously monitor the external display's position and state. This feedback loop provides real-time information about window or sunroof movement, enabling the processor to recalculate and adjust the displayable area parameters dynamically, ensuring virtual content remains properly positioned and visible throughout the vehicle interior.
2Reliability
If the system monitors and adjusts for external display movement, then display continuity is maintained, but the processing requirements and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing the relationship between external displays and displayable areas during stable conditions. When movement is detected, the system uses this pre-established spatial relationship as a baseline for quick adjustments, rather than performing complete recalculations from scratch. This reduces processing energy while maintaining display continuity.
Solution Approach 2:
The patent implements partial monitoring by focusing computational resources on detecting and responding to actual movement events rather than continuously processing all possible parameters at full resolution. The system activates intensive processing only when movement is detected, using lighter-weight algorithms during stable periods, thereby reducing overall energy consumption while maintaining reliability.

AI summary
A wearable electronic device may include a camera, a display, and at least one processor operatively connected, directly or indirectly, to the camera, and the display, wherein the at least one processor may be configured to identify a displayable area corresponding to an external display included in an image of a space acquired through the camera, identify, based on at least a portion of the external display being excluded from the displayable area due to movement of the external display, a first area of the displayable area, in which a portion of the external display is disposed and a second area of the displayable area, which corresponds to a remaining area excluding the first area, and control the display to display a virtual screen on the second area.
