Solution Overview
Problem
Current augmented reality systems lack effective methods for visualizing real-time physical characteristics of objects in the real world, such as stress on bridges or health metrics, with limited ability to dynamically update and overlay interactive information based on live data.
Innovation Solution
A system and method where a server computes physical characteristics of objects using live data from sensors and generates visualizations, which are then communicated to a viewing device to be overlaid on images of the objects, allowing for real-time updates and interactive displays based on position and orientation.

Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality systems overlay static information on real-world objects, then the system complexity is low, but the ability to dynamically update and visualize real-time physical characteristics is limited
Solution Approach 1:
The system divides the augmented reality functionality into separate modules: a sensor module for capturing real-time data, a processing module for computing physical characteristics, and a display module for rendering visualizations. This segmentation allows each component to specialize in specific tasks, enabling dynamic updates of physical characteristics without requiring the entire system to be complex.
Solution Approach 2:
The patent introduces an intermediary processing layer between the sensors and the display that computes physical characteristics from raw sensor data. This intermediary module handles the complex computations of deriving stress, strain, temperature, and other physical properties, allowing the AR system to display real-time physical characteristics without requiring complex integrated hardware.
2Loss of information
If the system processes and displays multiple physical characteristics in real-time, then the information completeness improves, but the processing time and computational load increase
Solution Approach 1:
The system applies local quality by selecting and visualizing only the most relevant physical characteristics for the specific object and context being observed. Rather than processing all possible physical parameters simultaneously, the system identifies key characteristics (such as stress points on a bridge or temperature on a engine component) and focuses computational resources on those specific measurements, maintaining information completeness for critical data while reducing overall processing time.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting which physical characteristics are computed and displayed based on the object type, user preferences, and current operational context. The system can switch between different sets of physical parameters (e.g., displaying stress and strain for structural objects, or temperature and pressure for thermal systems), optimizing processing time by only computing the relevant parameters for each situation rather than all parameters continuously.
3Ease of operation
If the AR system provides detailed real-time data overlays, then the user interaction quality improves, but the visual clarity and ease of operation may deteriorate due to information overload
Solution Approach 1:
The patent employs another dimension by utilizing spatial positioning and depth information to layer multiple physical characteristic visualizations in three-dimensional space rather than stacking them in two dimensions. Different physical parameters are displayed at different depths, angles, or distances from the object, allowing users to interact with and focus on specific characteristics without being overwhelmed by a flat, crowded display. This dimensional separation maintains visual clarity while providing comprehensive real-time data.
Solution Approach 2:
The system implements dynamics by making the information display adaptive and interactive rather than static. Users can dynamically select which physical characteristics to view, adjust the level of detail, and change the visualization style based on their needs. The system responds to user interactions by updating the displayed information in real-time, allowing users to drill down into specific parameters or switch between different views, thereby improving ease of operation while maintaining access to detailed real-time data.

AI summary
A system and method for visualization of physical characteristics are described. A sensor coupled to an object generates live data. Physical characteristics of the object are computed using the live data. A visualization of the physical characteristics of the object is generated and communicated to a viewing device configured to capture an image of the object. The viewing device augments the image of the object with the visualization of the physical characteristics of the object.
