Solution Overview
Problem
Wearable devices, such as augmented reality glasses, cause visual discomfort due to the movement of the device affecting the display state of virtual objects relative to fixed real-world objects.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wearable device moves with user body movements, then the device can be worn comfortably and naturally, but the display state of virtual objects becomes unstable and causes visual discomfort
Solution Approach 1:
The wearable device uses sensors to detect movement information in real-time and feeds this information back to the processor, which then adjusts the display state of virtual objects accordingly. This closed-loop feedback mechanism ensures that virtual objects remain stable relative to the user's field of view while allowing natural device movement with body motions.
Solution Approach 2:
The patent replaces mechanical stabilization mechanisms (such as gimbals or physical mounting systems) with sensor-based detection and software-based display adjustment. Instead of mechanically isolating the display from body movements, the system uses sensors to detect movements and computationally compensates for them by adjusting the virtual object's display position and orientation.
2Object-affected harmful factors
If the display state of virtual objects is corrected according to device movement, then visual comfort is improved, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The wearable device integrates multiple functions into a single system: the sensors serve both for detecting device movement and for triggering display corrections. The processor simultaneously performs movement analysis, display state calculation, and rendering control, eliminating the need for separate dedicated components for each function and reducing overall system complexity.
Solution Approach 2:
The patent combines the movement detection function and display correction function into a unified processing pipeline. The same sensor data used for basic device operation is also utilized for virtual object stabilization, merging multiple functions into a single integrated system rather than adding separate independent subsystems.
