Solution Approach 1:

The patent replaces traditional computational analysis methods with a visual-based analysis system. Instead of relying on complex computational algorithms to process EBSD data, the system converts crystal orientation data into visual representations (colors, shapes, patterns) that can be directly observed and analyzed, substituting computational processing with visual perception

Inventive Principle:

Solution Approach 2:

The patent applies color-coding to represent different crystal orientations and phases in the EBSD data. By mapping crystallographic information to visual color properties, the system enables rapid identification of crystal structure patterns without extensive computational analysis, directly addressing the need for faster analysis with reduced computational resources
