AR Glasses Multi-Sensor Tracking for Stable Virtual Object Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable electronic devices, such as augmented reality glasses, struggle with maintaining stable display of virtual objects due to movement relative to the user's body, leading to partial visibility of the objects as they shift with the user's movements.
Innovation Solution
Incorporating multiple sensors in different regions of the device to track movement, allowing the processor to adjust the display location of virtual objects based on combined movement information, ensuring stable visibility even when the device moves with the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single sensor is used to track device movement, then the device complexity is reduced, but the display stability of virtual objects deteriorates due to inability to accurately compensate for device movement
Solution Approach 1:
The device is divided into multiple regions with sensors strategically placed in each region (first sensor in first region, second sensor in second region). This segmentation allows independent measurement of movement in different areas, enabling more accurate compensation for device movement and maintaining virtual object stability without requiring a single complex sensor system.
2Reliability
If multiple sensors are deployed in different regions to track movement accurately, then the display stability of virtual objects is improved, but the device complexity increases
Solution Approach 1:
Movement information from multiple sensors disposed in different regions is combined and processed together to determine the overall device movement. The processor integrates data from the first sensor (first movement information) and second sensor (second movement information) to calculate compensation values, achieving accurate display stability through merged sensor input rather than requiring each sensor to independently provide complete movement data.
3Reliability
If the virtual object display location is adjusted based on movement information, then the display stability is improved, but the processing complexity increases
Solution Approach 1:
The system continuously acquires movement information from sensors, processes this feedback to determine device movement, and adjusts the virtual object display location accordingly. The processor uses the acquired first movement information and second movement information to calculate compensation values and update the display position in real-time, creating a closed-loop feedback system that maintains display stability through continuous adjustment based on actual device movement.

AI summary
An example wearable electronic device may include glass; a display which displays a virtual object through the glass; a first sensor disposed in a first region of the wearable electronic device; a second sensor disposed in a second region of the wearable electronic device; a memory; and at least one processor, wherein the memory stores at least one instruction which, when executed, causes the wearable electronic device to control the display to display a virtual object at a first location through the glass; acquire movement information of the first region through the first sensor and acquire movement information of the second region through the second sensor; and control the display to display the virtual object at a second location different from the first location based on the movement information of the first region and the movement information of the second region.
