See-Through Display Marking for Real-World Object Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality systems lack the ability to accurately and persistently mark the position of real-world objects on see-through displays, limiting their functionality and user interaction.
Innovation Solution
A method utilizing an imaging device, ranging device, inertial measurement unit, and global positioning system to capture and maintain the location of a real-world object on a see-through display, correlating the imaging device's field of view with the display to overlay a mark that remains locked to the object's position despite user movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mark is displayed on the see-through display at a location corresponding to the real world position of the object, then the marking precision and user interaction are improved, but the device complexity increases due to the need for imaging device, ranging device, inertial measurement unit, and global positioning system
Solution Approach 1:
The patent combines multiple sensing components (imaging device, ranging device, inertial measurement unit, global positioning system) into an integrated augmented reality system that shares common processing infrastructure and coordinate systems, allowing precise marking functionality while managing system complexity through unified architecture
Solution Approach 2:
The imaging device serves multiple functions: capturing real-world object images, determining viewing angles, and providing visual feedback to the user. This multi-functionality reduces the need for separate dedicated components for each measurement task, thereby improving marking precision without proportionally increasing device complexity
2Stability of the object's composition
If the mark remains locked to the object's position despite user movement, then the stability of the marking is improved, but the computational requirements and processing time increase
Solution Approach 1:
The system pre-establishes coordinate transformations and calibration data between the see-through display, imaging device, and navigation components before operation. This preliminary setup allows real-time mark stabilization without repeated complex calculations, maintaining mark stability while minimizing processing time during actual use
Solution Approach 2:
The inertial measurement unit continuously provides feedback on user movement and head orientation, allowing the system to proactively adjust mark position on the see-through display to maintain locking onto the real-world object. This continuous feedback loop stabilizes the mark while using efficient algorithms to keep processing time minimal

AI summary
A method for marking a position of a real world object on a see-through display is provided. The method includes capturing an image of a real world object with an imaging device. A viewing angle and a distance to the object are determined. A real world position of the object is calculated based on the viewing angle to the object and the distance to the object. A location on the see-through display that corresponds to the real world position of the object is determined. A mark is then displayed on the see-through display at the location that corresponds to the real world object.
