AR Portal Thickness via 3D Model Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality (AR) portals with perceivable thickness are lacking, leading to abrupt transitions between virtual scenes, resulting in a poor user experience due to the lack of immersion and adaptability in AR applications.
Innovation Solution
A method and apparatus for virtual scene switching in AR portals, where a terminal device displays a current virtual scene and a scene switching trigger, determines the relative position of a target virtual object to the trigger, and adds a 3D model matching the trigger's shape to lengthen the moving path, effectively increasing the portal's thickness and enhancing the traversal experience.

Engineering Contradiction Analysis
1Speed
If a virtual portal is implemented with zero or minimal thickness, then the scene switching is fast and efficient, but the user experience becomes abrupt and lacks immersion
Solution Approach 1:
The patent introduces a temporal dimension to the portal traversal experience. By adding a 3D model that persists during the traversal process, the system transforms an instantaneous 2D scene switch into a temporally extended 3D experience. The 3D model is added at the portal position and removed after traversal completes, creating a time-based narrative structure that enhances immersion without sacrificing switching efficiency
Solution Approach 2:
The 3D model serves as an intermediary element between the user and the scene transition. This mediator object provides visual and spatial context during the traversal, bridging the gap between the thin portal structure and the user's need for immersive experience. The 3D model acts as a temporary guide or companion that facilitates the transition without becoming a permanent obstacle
2Ease of operation
If a 3D model is added to lengthen the moving path, then the traversal experience becomes immersive and smooth, but the device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-defining portal positions and their associated 3D models before user interaction. When a user approaches a portal, the corresponding 3D model is automatically added at the predetermined portal location. This pre-planned structure allows the system to respond dynamically to user actions without requiring complex real-time calculations or ad-hoc model generation
Solution Approach 2:
The portal system implements dynamic behavior where 3D models are temporarily added to the scene based on user interaction with portals. The models appear when needed (when a user triggers a portal) and disappear when not needed (after traversal or when no portal is active), allowing the system to maintain simplicity during idle states while providing enhanced functionality during active use

AI summary
Embodiments of this application disclose a virtual scene switching method and apparatus, a terminal device, and a storage medium, to improve the service adaptability of a portal, improve the application scenario of the portal, and enhance traversal experience of a user. In this method, when a terminal device determines that a relative position between a target virtual object and a target scene switching trigger meets a predetermined position relationship, it may be determined that the target virtual object intends to pass through the target scene switching trigger. In this case, the terminal device may add a target 3D model to a position of the target scene switching trigger, and a moving path of the target virtual object passing through the target scene switching trigger is lengthened in a manner similar to thickening the target scene switching trigger, to implicitly increase the thickness of the target scene switching trigger, and reducing or even eliminating an abrupt feeling during a traversal, to allow the target virtual object to experience an immersive traversal.
