Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality systems are limited in comparing physical objects as they can only display a single characteristic of multiple physical objects, failing to generate virtual objects that dynamically display multiple characteristics for meaningful comparison, especially in scenarios involving relationships or tradeoffs between characteristics.
Innovation Solution
The implementation of a comparison system in augmented reality that detects physical objects and markers using image capture devices and machine learning models, associates markers with objects based on association distances, and generates virtual objects to display a subset of characteristics, enabling visual comparison through radar charts for multiple characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional augmented reality systems display only a single characteristic of physical objects through virtual objects, then the system complexity remains low, but the comparison capability is limited and insufficient for meaningful analysis
Solution Approach 1:
The patent segments the information display by creating multiple virtual objects, each representing a different characteristic of the physical object. Instead of overwhelming the user with all information at once, the system divides characteristics into separate virtual objects that can be individually viewed and compared, thereby enhancing comparison capability while managing system complexity through organized information presentation.
Solution Approach 2:
The patent transitions from displaying a single characteristic in one dimension to displaying multiple characteristics across multiple dimensions by generating multiple virtual objects. Each virtual object represents a different characteristic dimension, allowing users to compare physical objects across multiple attributes simultaneously, thus significantly improving versatility without proportionally increasing complexity.
2Loss of information
If augmented reality systems generate virtual objects based on information encoded in physical markers, then the information accuracy is high, but the information quantity is limited to what is encoded in the markers
Solution Approach 1:
The patent introduces an intermediary processing layer that receives the identifier from the physical marker and translates it into multiple characteristic values by querying a database. This intermediary process preserves the accuracy of the marker-based identification while expanding the information completeness by retrieving additional characteristics that are not directly encoded in the marker itself.
Solution Approach 2:
The system performs preliminary action by pre-storing characteristic information in a database associated with physical object identifiers. When a marker is detected, the system can quickly retrieve pre-prepared characteristic data, ensuring both accuracy (from the original marker) and completeness (from the database expansion) without real-time computation overhead.
3Productivity
If the system displays multiple characteristics of physical objects simultaneously, then the comparison capability is enhanced, but the information processing complexity increases
Solution Approach 1:
The patent creates virtual object copies that represent different characteristics of the same physical object. Instead of processing and displaying all raw data simultaneously, the system generates simplified virtual object copies, each highlighting specific characteristics for comparison. This copying approach enhances comparison efficiency by presenting processed, organized information while managing processing complexity through selective replication.

AI summary
In implementations of augmented reality systems for comparing physical objects, a computing device implements a comparison system to detect physical objects and physical markers depicted in frames of a digital video captured using an image capture device and displayed in a user interface. The comparison system associates a physical object of the physical objects with a physical marker of the physical markers based on an association distance estimated using two-dimensional coordinates of the user interface corresponding to a center of the physical object and a distance from the image capture device to the physical marker. Characteristics of the physical object are determined that are not displayed in the user interface based on an identifier of the physical marker. The comparison system generates a virtual object for display in the user interface that includes indications of a subset of the characteristics of the physical object.
