Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality systems lack the ability to seamlessly integrate virtual objects with real-world environments, particularly in providing instructions and maintaining consistent positioning and distance between virtual and real objects, especially when the user or device moves.
Innovation Solution
A method that utilizes wearable electronic devices to capture real objects, display virtual images adjacent to them, and adjust the virtual object's position and distance dynamically to maintain a consistent relationship with the real object, even as the user or device moves, using a combination of image processing and real-time feedback from sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual objects are displayed adjacent to real objects in augmented reality, then user guidance and instruction delivery are enhanced, but maintaining consistent positioning and distance between virtual and real objects becomes difficult when the user or device moves
Solution Approach 1:
The system continuously tracks the relative position and orientation between the wearable device and real objects using sensors (accelerometers, gyroscopes, cameras), and uses this feedback to dynamically adjust virtual object positioning. This closed-loop control ensures virtual objects remain accurately anchored to real objects even during user movement, resolving the contradiction between enhanced guidance and consistent positioning.
Solution Approach 2:
The virtual object positioning system transitions from static to dynamic adjustment, continuously adapting virtual object positions based on real-time sensor data. The system calculates transformation matrices that account for device motion, lighting changes, and perspective shifts, enabling virtual objects to maintain consistent spatial relationships with real objects during user movement.
2Measurement precision
If the virtual object's position and distance are adjusted dynamically to maintain consistent relationship with real objects, then positioning accuracy is improved, but system complexity increases due to real-time feedback from sensors and image processing
Solution Approach 1:
The wearable device integrates multiple functions into unified components: the camera serves both for capturing images and for visual feedback, while sensors simultaneously track position, orientation, and motion. This multi-functionality reduces the number of separate components needed, managing system complexity while achieving high positioning accuracy through coordinated operation of these universal elements.
Solution Approach 2:
The system replaces complex mechanical positioning mechanisms with computational approaches. Instead of physical alignment mechanisms, the patent uses image processing algorithms, sensor fusion, and mathematical transformation matrices to achieve precise virtual object positioning. This substitution of mechanical systems with computational methods reduces physical complexity while maintaining or improving positioning accuracy.
