AR Marker De-duplication via Author Location Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality applications face the challenge of AR marker overload, where multiple markers from various users and locations are displayed simultaneously, leading to information overload and reduced user engagement due to the lack of effective de-duplication and prioritization methods.
Innovation Solution
A method and system for augmented reality marker de-duplication and instantiation using marker creation information, which identifies the location of objects of interest, receives and de-duplicates markers based on metadata such as author location and time of authorship, and prioritizes them by distance and relevance, grouping them into layers for optimized display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple markers from various users and locations are displayed simultaneously in augmented reality, then the quantity of information provided increases, but information overload occurs and user engagement decreases
Solution Approach 1:
The patent extracts and removes duplicate or less relevant markers from the set of markers to be displayed. By identifying markers with identical or substantially similar content and selectively excluding them, the system reduces the quantity of displayed markers while preserving the most relevant information, thereby preventing information overload.
Solution Approach 2:
The patent changes the parameters used for marker selection by introducing metadata-based filtering criteria (author location, time of authorship, distance measures) rather than simply displaying all markers. This parameter-based filtering transforms the marker set from an unfiltered collection to a prioritized subset, reducing information overload while maintaining quality.
2Loss of information
If all received markers are displayed without de-duplication, then complete information is provided, but display complexity and processing requirements increase
Solution Approach 1:
The patent performs preliminary de-duplication and filtering of markers before they are displayed to the user. By pre-processing the marker data using metadata comparison and distance calculations, the system eliminates duplicates in advance, reducing the complexity of the display operation while ensuring that complete and accurate information is preserved in the filtered result.
3Adaptability or versatility
If markers from distant locations are included equally with nearby markers, then comprehensive coverage is achieved, but relevance to the user's current context decreases
Solution Approach 1:
The patent applies local quality by differentiating marker relevance based on the author's location relative to the user. Markers from authors located near the user or object of interest are prioritized and displayed with higher prominence, while markers from distant locations are either filtered out or displayed with lower priority. This location-based differentiation ensures that displayed markers are contextually relevant to the user's current situation.

AI summary
An object of interest in an augmented reality view within a display of an augmented reality device is identified. A location of the object of interest is determined. A plurality of markers related to the object of interest is received. Metadata information associated with each of the plurality of markers is received. The metadata includes an indication of a location of an author of the marker at a time of authorship of the marker. The location of each of the plurality of markers is determined based upon the metadata information. A distance measure between the location of each of the plurality of markers and the location of the object of interest is determined. The plurality of markers are de-duplicated to form a subset of the plurality of markers based upon the determined distance measures. The subset of markers is sent to the augmented reality device.
