Transparent Display Coordinate System for Reduced Computation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transparent display systems require time-consuming recalculations of virtual object positions when the display screen's posture changes, necessitating repeated coordinate system reconstructions and position calculations for users and physical objects.
Innovation Solution
A display system comprising a light transmissive screen, first and second information extraction devices, and a processing device that constructs a fixed reference coordinate system, initially locates user, target object, and screen positions, and updates the fused image based on movement amounts of the screen and user, reducing the need for constant coordinate recalculations.

Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen posture changes, then the system can adapt to new positions and orientations, but the computation time increases due to repeated coordinate system construction and position calculations
Solution Approach 1:
The patent pre-establishes a fixed reference coordinate system before the display screen posture changes. By having the coordinate system ready in advance rather than constructing it during each posture change event, the system reduces computation time while maintaining adaptability to new positions and orientations.
Solution Approach 2:
The patent transforms the coordinate system from a static, repeatedly reconstructed structure to a dynamic fixed reference system. The fixed reference coordinate system remains stable while only the position relationships of objects relative to this fixed system are updated, reducing computational overhead during posture changes.
2Measurement precision
If the coordinate system is reconstructed for each posture change, then accurate position calculation is achieved, but the system complexity and computational load increase
Solution Approach 1:
The fixed reference coordinate system is established beforehand, serving as a pre-prepared framework for all subsequent position calculations. This preliminary action eliminates the need for repeated coordinate system construction, reducing system complexity while maintaining calculation accuracy through the stable reference framework.
Solution Approach 2:
Instead of reconstructing the entire coordinate system, the patent uses the fixed reference coordinate system as a template and only updates the position relationships of specific objects relative to this fixed framework. This copying approach maintains accuracy while reducing computational complexity.

AI summary
A method for information display, a processing device, and a display system are disclosed. The display system includes a light transmissive display screen, at least one first information extraction device, at least one second information extraction device, and a processing device.
