Mixed Reality Interference Visualization for Virtual Object Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mixed reality systems struggle to effectively present the extent of interference between virtual objects, as they only sequentially link interference positions with line segments, making it difficult to determine the extent of interference traces.
Innovation Solution
An information processing apparatus that acquires real-space images, stores virtual object models, determines interference between objects, records interference information, generates composite images showing interference outlines, and outputs these images to a display, allowing for the presentation of interference shapes and history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sequential linking with line segments is used to record interference positions, then the system can track interference occurrences, but it becomes difficult to determine the extent of interference traces
Solution Approach 1:
The patent creates a visual copy of the interference trace by projecting the sequence of interference positions onto the three-dimensional model of the component. This allows the interference extent to be directly visualized on the component model, making it easy to understand the spatial distribution and magnitude of interference without complex data processing.
Solution Approach 2:
The patent transforms the one-dimensional sequential linkage of interference positions into a two-dimensional visual representation on the three-dimensional component model. By mapping interference trace information onto the surface or volume of the component, the system provides intuitive spatial understanding of interference extent across multiple dimensions.
2Measurement precision
If detailed interference trace information is recorded and visualized, then the understanding of interference extent improves, but the system complexity and processing requirements increase
Solution Approach 1:
Instead of processing and analyzing complex interference trace data, the system creates a visual copy by overlaying the interference positions onto the component model. This approach maintains high measurement precision while avoiding complex processing, as the visualization directly represents the interference extent without requiring additional computational analysis.
Solution Approach 2:
The patent replaces complex mechanical or computational analysis systems with a visual information processing approach. By using graphical representation of interference traces on the component model, the system achieves precise interference measurement through visual intuition rather than complex mathematical processing or additional hardware.
