Map Annotation Texture Mapping on 3D Object Faces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack an intuitive and simple method to display map information, particularly in associating annotations with physical objects in a visually clear and interactive manner.
Innovation Solution
The system generates an annotation representation as a texture on a polygon corresponding with the face representation of a physical object, allowing for the display of annotations in relation to the object, with features like association designation, offset positioning, and alignment with geometric normal directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If annotations are displayed as separate elements from physical object representations, then annotation information can be clearly distinguished, but the association between annotations and physical objects becomes less intuitive
Solution Approach 1:
The patent merges the annotation representation with the physical object representation by displaying the annotation as a texture on the polygon representing the physical object. This integration allows users to see both the object and its annotations in a unified visual context, making the association intuitive while maintaining annotation distinguishability through texture differentiation.
2Ease of operation
If annotations are displayed directly on physical object representations, then the association becomes more intuitive, but annotation information may become less distinguishable from the object itself
Solution Approach 1:
The patent applies local quality by using texture mapping to display annotations on specific portions (faces) of the three-dimensional polygon representing the physical object. The texture provides visual differentiation between the annotation content and the underlying object geometry, allowing clear distinction while maintaining spatial association. Different textures or color mappings can be applied to different annotation types or importance levels.
3Loss of information
If multiple annotations are associated with different portions of a physical object, then detailed information can be provided for each portion, but the complexity of managing and displaying these annotations increases
Solution Approach 1:
The patent segments the physical object representation into multiple discrete faces or portions, with each face capable of having its own texture mapping for annotations. This segmentation allows detailed information to be associated with specific portions of the object while the system manages complexity by handling each face independently through standardized texture mapping operations.
Solution Approach 2:
The patent implements a universal texture mapping mechanism that can handle multiple annotation types, sizes, and positions across different faces of the three-dimensional polygon. This multi-functional approach allows the same basic technique to manage diverse annotation requirements, reducing overall system complexity despite the detailed information being conveyed.
4Measurement precision
If the electronic apparatus provides detailed control over annotation positioning and association, then precision in annotation placement is improved, but the ease of use decreases due to increased control parameters
Solution Approach 1:
The patent enables self-service by allowing users to directly interact with the three-dimensional polygon representation and automatically associate annotations with the appropriate faces or portions. The system automatically handles the complex positioning and texture mapping calculations, providing precision placement without requiring users to manually configure multiple control parameters. Users simply indicate the desired association, and the system manages the detailed positioning autonomously.
