Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing viewer applications require device-specific modifications for zooming and panning operations due to varying display resolutions, leading to decreased performance across different computing devices.
Innovation Solution
A viewer application modifies a view-to-image transformation matrix based on user input to convert resolution-based coordinates to resolution-independent coordinates, allowing for consistent interactive operations across different display devices without needing device-specific customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If device-specific modifications are made for zooming and panning operations, then the operations can be optimized for specific display resolutions, but the application complexity increases and performance decreases across different computing devices
Solution Approach 1:
The patent transforms the coordinate system parameters from resolution-based to resolution-independent coordinates. This allows the same application logic to work across different display resolutions by changing the parameter space rather than modifying the application structure for each device.
Solution Approach 2:
The patent creates a universal coordinate transformation system that works across all display resolutions. The resolution-independent coordinate system serves as an intermediary that enables the same viewer application to function correctly on devices with different screen resolutions without device-specific modifications.
2Measurement precision
If device-specific modifications are made for different display resolutions, then the operations can be optimized for each device, but the rendering and downloading performance decreases
Solution Approach 1:
By changing from resolution-based to resolution-independent coordinates, the patent eliminates the need for multiple device-specific rendering paths. This single unified approach improves rendering performance by avoiding the overhead of device-specific code execution while maintaining display precision through the transformation matrix.
3Ease of manufacture
If resolution-based coordinates are used for zooming and panning, then the operations can be implemented simply, but the application requires different operations for different display devices reducing versatility
Solution Approach 1:
The patent introduces resolution-independent coordinates as an intermediary layer between the user interface operations and the actual display rendering. This intermediary coordinate system maintains implementation simplicity while enabling cross-device compatibility, as it translates user actions into a universal coordinate space that can be adapted to any resolution.
4Measurement precision
If different zooming and panning operations are used for different display devices, then the display precision can be optimized, but the code complexity and maintenance difficulty increases
Solution Approach 1:
The patent changes the fundamental parameter from resolution-based coordinates to resolution-independent coordinates. This single parameter change eliminates the need for multiple device-specific operation sets, reducing code complexity while maintaining display precision through the transformation matrix calculations.
