Location-Based Virtual Object Access in Collaborative AR Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality and augmented reality technologies lack effective methods for enabling collaborative sessions with selective access to virtual objects based on geographical proximity, limiting immersive and interactive experiences.
Innovation Solution
A collaborative method is implemented where virtual objects are associated with geographical locations, allowing access based on proximity, using advanced AR technologies like computer vision and object tracking, and incorporating wearable devices with cameras and touch-sensitive inputs for intuitive navigation and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual objects are made accessible to all users in VR/AR environments, then user interaction and collaboration are enhanced, but control over access and privacy protection deteriorate
Solution Approach 1:
The patent introduces geographical location data and proximity detection mechanisms as intermediaries between users and virtual objects. The system automatically determines access rights based on physical proximity to real-world locations, serving as a mediator that grants or denies access without requiring complex manual authorization protocols. This resolves the contradiction by providing adaptive access control through location-based automation.
Solution Approach 2:
The system implements self-service access control where virtual objects automatically manage their own accessibility based on predefined geographical parameters. The virtual environment autonomously evaluates user proximity to designated locations and adjusts access permissions accordingly, eliminating the need for external administrators to manually manage access rights for each interaction.
2Adaptability or versatility
If geographical proximity-based access control is implemented, then selective access to virtual objects is improved, but technical complexity of the system increases
Solution Approach 1:
The patent leverages the universal functionality of existing mobile device location services (GPS, cellular triangulation, Wi-Fi positioning) to enable geographical proximity-based access control. By reusing established positioning infrastructure for a new access control application, the system achieves selective access capabilities without adding significant technical complexity, as the core location detection functions already exist in standard devices.

AI summary
Collaborative sessions in which access to added virtual content is selectively made available to participants/users. A participant (the host) creates a new session and invites participants to join. The invited participants receive an invitation to join the session. The session creator (i.e., the host) and other approved participants can access the contents of a session. The session identifies a new participant when they join the session, and concurrently notifies the other participants in the session that a new participant is waiting for permission to access the added virtual content. The host or approved participants can set up the new participant with permissions for accessing added virtual content.
