Solution Overview
Problem
Location-based AR software applications face challenges with network load and connectivity issues, particularly when multiple users are in close proximity, leading to a negative impact on user experience.
Innovation Solution
A computing device that selects physical locations for placing virtual objects in AR software applications based on an expected user location and spatially-dependent attributes such as wireless connection performance or sound perception, to enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If virtual objects are deployed at physical locations based on user position in location-based AR games, then user engagement and interaction with virtual objects is improved, but network load increases and connectivity issues occur when multiple users are in close proximity
Solution Approach 1:
The system performs preliminary actions by predicting future user positions and pre-deploying virtual objects at those locations before users actually arrive. This proactive approach distributes network traffic over time and space, preventing the concentration of multiple users at the same location simultaneously, thereby reducing network load and connectivity issues while maintaining high user engagement.
2Productivity
If virtual objects are placed at user's current location to maximize immediate interaction, then user engagement is improved, but users frequently move to new locations causing continuous network requests and increased network load
Solution Approach 1:
The system predicts where users will move next and pre-loads virtual objects at those future locations. This eliminates the need for continuous network requests as users move, because objects are already cached at their destination. Users maintain high interaction levels while network load is significantly reduced by eliminating redundant data transmissions.
3Adaptability or versatility
If virtual objects are deployed without considering spatial attributes, then deployment flexibility is improved, but user experience deteriorates in areas with poor wireless connectivity or sound quality
Solution Approach 1:
The system evaluates spatially-dependent attributes such as wireless connectivity quality and sound perception at different physical locations before deploying virtual objects. Objects are selectively deployed only at locations where these attributes meet quality thresholds, ensuring consistent user experience. This local quality assessment maintains deployment flexibility while preventing placement in areas with poor connectivity or audio quality.

AI summary
A computing device for supporting an Augmented-Reality (AR) software application is provided. The computing device is operative to select a physical location for placing a current virtual object, where the current virtual object appears to be placed when overlaid onto a video sequence capturing a physical scene in the surroundings of a user, based on an expected physical location which the user assumes in response to displaying the physical scene and the overlaid current virtual object to the user, and an attribute which is spatially dependent and which has an impact on a user experience of the AR software application. Taking the spatially-dependent attribute at the expected physical location of the user into consideration in selecting physical locations for placing virtual objects is advantageous in that virtual objects may be deployed at physical locations so as to provide an improved, or at least satisfactory, user experience to the users.
