Touch Input Correction for Multi-Form Factor IHS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-form factor Information Handling Systems (IHS) face challenges in maintaining accurate touch input due to variations in posture and orientation, leading to inconsistent user experiences as the parallax effect changes with device configuration.
Innovation Solution
The system identifies the current posture and orientation of dual-display IHS using sensors and calculates adjusted parallax values to correct touch inputs, ensuring accurate mapping of touch events across different configurations by remapping contact locations on the touchscreen to display locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device supports multiple postures and orientations, then versatility and adaptability are improved, but touch input accuracy deteriorates due to parallax effects
Solution Approach 1:
The system dynamically adjusts parallax correction values based on the current posture and orientation of the device. Sensors detect changes in device configuration, and the system automatically updates the parallax correction parameters to maintain accurate touch input mapping across laptop, tablet, and other display postures
Solution Approach 2:
The invention changes the parallax correction parameters according to the detected posture and orientation. By storing multiple sets of parallax values corresponding to different device configurations and selecting the appropriate set based on current sensor readings, the system maintains touch accuracy across varying form factors
2Measurement precision
If parallax values are dynamically adjusted for different postures, then touch input accuracy is improved, but device complexity increases
Solution Approach 1:
The system uses sensors to continuously monitor device posture and orientation, providing feedback to the touch input processing system. This feedback loop enables automatic adjustment of parallax correction values without user intervention, maintaining accuracy while managing complexity through automated control
Solution Approach 2:
The system performs self-calibration by automatically detecting its own posture and orientation through integrated sensors and adjusting the appropriate parallax correction values without requiring external calibration tools or manual user configuration
