3D Display Rendering via Spatial Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3D multi-screen applications, achieving seamless spatial synchronization of virtual objects across multiple displays is challenging, as existing technologies focus primarily on time synchronization, neglecting the importance of spatial synchronization for an immersive user experience.
Innovation Solution
A method and apparatus that determine the appropriate 3D display for rendering an object based on its position and posture within a global coordinate system relative to the user's viewpoint, using eye-tracking and coordinate transformation techniques to ensure seamless object transfer between displays.

Engineering Contradiction Analysis
1Loss of time
If time synchronization is implemented for multi-screen applications, then content alignment across different devices is improved, but spatial synchronization and immersive user experience deteriorate
Solution Approach 1:
The patent transitions from 2D time-synchronization to 3D spatial synchronization by introducing depth dimension and viewing angle considerations. The system determines which display to render objects on by calculating spatial relationships in 3D space, including distance from user's eyes to display and angular positions, thereby creating immersive experiences that 2D synchronization cannot achieve.
2Manufacturing precision
If virtual objects are transferred between 3D displays, then spatial synchronization is improved, but rendering determination complexity increases
Solution Approach 1:
The patent introduces a rendering determination module as an intermediary that centralizes the complex spatial calculation logic. This module receives object position information, calculates spatial relationships with multiple displays, determines the appropriate display for rendering, and manages the transfer decisions, thereby organizing complexity in a manageable way while maintaining high spatial synchronization precision.
