Dynamic Hover Sensitivity in Dual Display Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-display information handling systems face challenges in optimizing touch-screen sensitivity and gesture detection across multiple screens, particularly in dynamically changing environments and usage modes, leading to inefficiencies in power consumption and accuracy.
Innovation Solution
The integration of a sensor module and power management system that uses a combination of orientation sensors, cameras, and touch controllers to dynamically adjust touch-screen sensitivity and power modes based on the relative orientation of the screens and active software applications, enabling adaptive power management and precise gesture detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If touch-screen sensitivity is increased to improve gesture detection accuracy, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The system dynamically adjusts touch-screen sensitivity based on the active application and device orientation. The power management system changes the sense state between high-power/high-precision and low-power/low-precision modes, making the sensitivity adaptive rather than static. This resolves the contradiction by applying high measurement precision only when necessary for the current usage context.
Solution Approach 2:
The patent changes the sensitivity parameter of the touch-screen based on external conditions (application type, orientation). By adjusting the sense state parameter dynamically, the system achieves high gesture detection accuracy when needed while consuming less power during normal operation, thus resolving the trade-off between precision and energy consumption.
2Measurement precision
If high sensitivity mode is used continuously to maintain accurate touch and hover detection, then measurement precision is improved, but loss of energy increases
Solution Approach 1:
The system periodically evaluates the current usage context (active application, device orientation) and adjusts the touch-screen sensitivity accordingly. Instead of maintaining high sensitivity continuously, the system switches between high-power and low-power modes based on periodic context assessment, reducing energy loss while maintaining accuracy when needed.
Solution Approach 2:
The power management system receives feedback about the current application and orientation state, then adjusts the touch-screen sensitivity in response. This feedback loop ensures that high measurement precision is maintained only when the context requires it, preventing unnecessary energy consumption during normal usage scenarios.
3Adaptability or versatility
If the system dynamically adjusts sensitivity based on application context, then adaptability is improved, but device complexity increases
Solution Approach 1:
The power management system serves multiple functions: it manages overall device power, monitors application context, detects orientation, and controls touch-screen sensitivity. By making the power management system universal and multi-functional, the patent achieves high adaptability without adding separate dedicated components for each function, thus limiting the increase in device complexity.
