Solution Overview

Problem

Conventional maps in virtual spaces, obtained by reducing the space at a uniform magnification, suffer from poor visibility, making it difficult for users to identify important objects, especially on smaller display screens.

Innovation Solution

The proposed solution involves a computer program and method that display a virtual space map using non-uniform, distorted scaling instead of uniform magnification, allowing for improved visibility by emphasizing certain objects and reducing the size of others accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If uniform magnification is used to reduce virtual space, then coordinate accuracy is maintained, but visibility of important objects deteriorates

Engineering Contradiction:

Improvecoordinate accuracyVSAvoidvisibility of important objects

Core Design Contradiction:

Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies non-uniform magnification where different regions of the virtual space are scaled at different rates. Important objects are positioned in regions with higher magnification to enhance their visibility, while less important regions use lower magnification. This local differentiation allows the map to maintain coordinate accuracy for navigation while improving visibility of key elements.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces asymmetric distortion to the map projection, where the scaling factors differ along different axes or regions. This asymmetric approach allows important objects to be emphasized through localized expansion while maintaining overall coordinate relationships for navigation purposes.

Inventive Principle:

Principle #4Asymmetry

2Difficulty of detecting and measuring

If non-uniform magnification is used to improve visibility, then visibility of important objects improves, but coordinate correspondence between virtual space and map deteriorates

Engineering Contradiction:

Improvevisibility of important objectsVSAvoidcoordinate correspondence

Core Design Contradiction:

Difficulty of detecting and measuringVSMeasurement precision

Solution Approach 1:

The patent dynamically adjusts magnification parameters based on the content being displayed. When important objects are detected, the system changes the magnification parameter for that specific region to enhance visibility. The system maintains a transformation matrix that tracks the relationship between original and distorted coordinates, allowing accurate coordinate correspondence to be preserved despite non-uniform scaling.

3Area of stationary object

If map scale is reduced for smaller display screens, then display size is optimized, but visibility of important objects deteriorates

Engineering Contradiction:

Improvedisplay area utilizationVSAvoidvisibility of important objects

Core Design Contradiction:

Area of stationary objectVSDifficulty of detecting and measuring

Solution Approach 1:

The patent segments the virtual space into multiple regions with different magnification levels. Important objects are placed in regions with higher magnification, allowing them to remain visible even when the overall map scale is reduced for small display screens. This segmentation enables the system to optimize display area utilization while maintaining visibility of key elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a dimensional transformation by applying non-uniform scaling that operates independently in different spatial dimensions. This allows the system to compress the map in certain directions while expanding it in others, effectively utilizing limited display area while maintaining visibility of important objects through strategic dimensional manipulation.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
