Auxiliary Display Scaling Factor for Content Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-display systems face challenges in maintaining the original size and appearance of content when transferring objects between displays with different physical sizes, resolutions, or PPI, as users must manually adjust scaling, which is time-consuming and frustrating, and there is no method to automatically apply a consistent scaling factor.
Innovation Solution
A method that automatically applies a scaling factor to an auxiliary display based on user input and the predetermined size of an object on a primary display, using a calculated scaling factor to maintain the object's physical dimensions across displays, allowing for seamless transfer of content without manual scaling adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is transferred between displays with different physical sizes and resolutions, then the content can be viewed on multiple display devices, but the content size and appearance change due to different PPI and scaling factors
Solution Approach 1:
The system pre-calculates and stores the scaling factor for the auxiliary display based on its physical characteristics (diagonal size and resolution). When content is transferred from the primary display, this pre-calculated scaling factor is automatically applied to maintain consistent content dimensions across displays with different PPI, eliminating the need for real-time calculation and ensuring size consistency.
2Ease of operation
If manual scaling adjustments are required for each display, then content size can be customized, but user time and operational complexity increase
Solution Approach 1:
The system automatically determines the appropriate scaling factor for the auxiliary display based on its pre-stored physical characteristics and the content's original dimensions. This self-service mechanism eliminates the need for manual user intervention in scaling adjustments, allowing content to be transferred and automatically resized according to the auxiliary display's properties, thereby saving user time and simplifying operation.
3Manufacturing precision
If a fixed scaling factor is applied to the auxiliary display, then content size consistency is maintained, but the system cannot adapt to different display configurations
Solution Approach 1:
The system assigns a specific scaling factor to each auxiliary display based on its unique physical characteristics (diagonal size and resolution). This local quality approach ensures that each display receives the appropriate scaling treatment tailored to its properties, maintaining content dimension accuracy on that specific display while allowing the system to support multiple auxiliary displays with different configurations, thus achieving both precision and flexibility.
