Adaptive Mouse Resolution for Consistent Multi-Display Cursor Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling system mice face challenges in managing power consumption and maintaining consistent cursor movement across displays with different resolutions, particularly when transitioning between them.
Innovation Solution
An adaptive system adjusts mouse position sensor sensitivity and button press sensitivity based on usage context, such as accelerations and button press frequency, and automatically adjusts resolution to match display resolution to maintain consistent cursor movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high precision position sensor is used, then measurement precision is improved, but use of energy worsens
Solution Approach 1:
The patent implements dynamic switching between high precision and standard precision modes based on application context. The system automatically adjusts position sensor precision requirements according to the detected usage scenario (gaming, productivity, media consumption), allowing the mouse to consume more power only when high precision is actually needed for gaming applications, while saving power during standard productivity tasks
Solution Approach 2:
The system changes the precision parameter of the position sensor dynamically based on application type. By adjusting the precision level according to whether the system is in gaming mode or standard mode, the patent optimizes the balance between measurement precision and power consumption, ensuring high precision is maintained only when necessary
2Measurement precision
If high precision position sensor is used, then measurement precision is improved, but device complexity worsens
Solution Approach 1:
The patent implements self-service through automatic application detection and mode switching. The system uses built-in accelerometers and context detection algorithms to automatically identify whether a gaming or productivity application is running, then autonomously adjusts the position sensor precision without requiring user intervention or complex manual configuration
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring application context through accelerometers and software hooks, then using this feedback to dynamically adjust position sensor precision. This closed-loop approach allows the mouse to automatically adapt to changing usage scenarios, maintaining high precision only when gaming applications are detected
3Adaptability or versatility
If mouse resolution is adjusted for different display resolutions, then adaptability is improved, but device complexity worsens
Solution Approach 1:
The patent uses feedback from display resolution detection to automatically adjust mouse resolution settings. The system monitors the connected display's resolution characteristics and dynamically adjusts the position sensor reporting rate and cursor speed accordingly, eliminating the need for manual user configuration and simplifying the user experience while maintaining compatibility across different display types

AI summary
An information handling system mouse includes a position sensor that detects movement of the mouse and reports the movement to generate cursor movement at plural displays interfaced with the information handling system. The mouse automatically changes between a first position resolution and a second position resolution to generate cursor movement based upon a resolution of a display at which the cursor is presented. As the cursor moves between each of plural displays in response to mouse movement, the mouse automatically changes the position resolution so that cursor movement relative to the mouse movement remains consistent even where the cursor is presented at displays having different display resolutions.
