Augmented Reality Content Placement via Feature Density Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality systems face challenges in automatically placing virtual content in a way that avoids obscuring important parts of real-world objects while ensuring sufficient features for object recognition and tracking, especially when the user zooms in.
Innovation Solution
A method is developed to determine optimal placement of virtual content by calculating feature density within and around potential regions, using a probabilistic framework to balance the need to avoid obscuring salient features and ensure sufficient features for recognition, and considering prior probabilities and restrictions on placement.

Engineering Contradiction Analysis
1Productivity
If virtual content is automatically placed in relation to a recognized object, then content placement efficiency is improved, but the content may obscure important parts of the object or be placed in areas with insufficient features for recognition and tracking
Solution Approach 1:
The system performs preliminary analysis of the reference image to identify feature-rich regions and salient object parts before placing virtual content. By pre-determining suitable placement zones that avoid critical features, the system ensures both efficient automatic placement and maintained recognition reliability.
Solution Approach 2:
The system applies different placement strategies to different regions of the object based on local feature density and importance. Areas with high feature density or salient characteristics are protected from content placement, while regions with sufficient but not critical features are designated as suitable placement zones.
2Area of stationary object
If virtual content is placed to cover maximum area, then visibility of content is improved, but object recognition features may be obscured
Solution Approach 1:
The system adjusts placement parameters (position, size, orientation) of virtual content based on the analyzed feature distribution in the reference image. By dynamically changing these parameters to optimize for both area coverage and feature preservation, the system achieves maximum content visibility without obscuring critical recognition features.
3Device complexity
If content is placed without considering feature density, then placement complexity is reduced, but user experience deteriorates due to obscuring important object parts
Solution Approach 1:
The system performs preliminary analysis of the reference image to pre-identify suitable placement regions with sufficient feature density. This pre-processing step creates a map of acceptable zones that guides subsequent content placement, maintaining simplicity while ensuring good user experience.

AI summary
A method for improving the placement of virtual content in augmented reality is disclosed. A reference image of the object to be augmented is analyzed for feature density information. The placement of content is based on the at least one location adjacent to where features are concentrated. Accordingly, the chance of the content interfering with an important part of the object is lowered, and object recognition and/or tracking ability is maintained because there are sufficient features nearby the content to enable object recognition and/or tracking.
