Wearable Display Stabilization via Motion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices, such as AR glasses, cause visual discomfort due to virtual objects shaking when the user moves, as they are not effectively adjusted for movement.
Innovation Solution
A wearable device equipped with sensors and a display module, controlled by a processor, adjusts the display state of virtual objects based on user movement to maintain their position and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual objects are displayed through wearable device without correction, then the display is simple and responsive to device movement, but the virtual objects shake and cause visual discomfort to the user
Solution Approach 1:
The system uses sensors to detect wearable device movement and feeds this information back to the processor, which then corrects the virtual object display position and orientation accordingly. This closed-loop feedback mechanism eliminates visual discomfort caused by shaking virtual objects while maintaining system responsiveness.
Solution Approach 2:
The patent replaces mechanical stabilization (physical mounting systems) with computational correction. The processor calculates compensation transformations based on sensor data and applies software-based position and orientation adjustments to virtual objects, substituting mechanical complexity with algorithmic processing.
2Reliability
If the display state of virtual objects is corrected according to movement, then visual comfort is improved, but the processing and control complexity increases
Solution Approach 1:
The system performs preliminary detection of device movement using sensors before rendering virtual objects. By identifying movement in advance and pre-calculating correction parameters, the system stabilizes virtual object display without requiring complex real-time processing during rendering, thus reducing overall processing complexity.
Solution Approach 2:
The patent changes the parameters of virtual object display (position and orientation) based on detected movement. Instead of complex transformations, the system adjusts key display parameters dynamically, simplifying the processing required to maintain virtual object stability while improving reliability.
