Mouse DPI Adjustment via Host Screen Size Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical mice output a fixed DPI value, causing user annoyance when switching between display devices of different screen sizes, requiring manual adjustments that are inconvenient, especially when multiple devices are used.
Innovation Solution
A computer system and method where the DPI value of a mouse device is automatically adjusted based on the screen size of the current display device, with the host detecting screen sizes and outputting signals for the mouse to adjust DPI values, allowing seamless cursor control across different displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed DPI value is used in the mouse device, then the device structure is simple, but the user experience deteriorates when switching between display devices of different screen sizes
Solution Approach 1:
The patent applies the dynamics principle by making the DPI value adjustable and adaptive rather than fixed. The mouse device dynamically changes its DPI setting based on the detected display device characteristics, allowing optimal performance across different screen sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements parameter changes by modifying the DPI value according to the screen size of the display device. The system detects the display device parameters and adjusts the mouse's DPI accordingly, enabling seamless transition between different display configurations without manual intervention.
2Adaptability or versatility
If manual DPI adjustment is provided, then the user can optimize cursor control for each display device, but the ease of operation deteriorates due to frequent manual changes
Solution Approach 1:
The patent applies the self-service principle by enabling the system to automatically detect the display device and adjust the DPI without user intervention. The mouse device autonomously optimizes its settings based on the detected display characteristics, eliminating the need for manual adjustment while preserving customization benefits.
Solution Approach 2:
The patent implements feedback by having the system detect the display device parameters and use this information to automatically adjust the DPI setting. This closed-loop mechanism ensures optimal performance is achieved automatically based on real-time detection, removing the burden of manual configuration.
3Adaptability or versatility
If multiple display devices with different screen sizes are used, then the system versatility is improved, but the user experience deteriorates due to cursor speed changes between displays
Solution Approach 1:
The patent applies dynamics by making the cursor speed adaptive rather than fixed. The system dynamically adjusts the cursor movement speed based on the detected display device, ensuring consistent and comfortable cursor control experience when switching between multiple display devices with different screen sizes.
Solution Approach 2:
The patent implements parameter changes by modifying the cursor speed parameter (DPI value) according to the display device characteristics. This ensures that when users switch between different display devices, the cursor speed automatically adjusts to maintain optimal performance and user experience across all displays.
