Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens in motion environments suffer from inaccuracy, latency, jitter, unintended touches, and reduced usability due to vehicle or user movement, leading to inaccurate and erratic touch inputs, especially in critical applications like cockpits and automobiles.
Innovation Solution
Implementing a motion stabilization model that adjusts and normalizes touch zones based on stabilized positions, using sensors and algorithms to correct for motion, ensuring accurate touch detection and integration into scene rendering, thereby stabilizing touch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch screens are used in motion environments, then the device can be operated during movement, but touch input accuracy deteriorates due to vehicle or user movement
Solution Approach 1:
The system uses motion sensors to detect device movement and provides feedback by adjusting touch zone positions in real-time to compensate for motion, maintaining accurate touch input detection despite device movement
Solution Approach 2:
The system dynamically changes the parameters of touch zones (position, size, shape) based on detected motion parameters, adapting the touch control system to motion conditions while preserving input accuracy
2Measurement precision
If touch zones are adjusted for motion compensation, then touch input accuracy improves, but system complexity increases
Solution Approach 1:
The system introduces motion sensors as an intermediary component that detects device movement and enables the touch zone adjustment mechanism, managing the complexity through a dedicated sensing layer
Solution Approach 2:
The system implements dynamic adjustment of touch zones based on real-time motion detection, allowing the touch control system to adapt to motion conditions while maintaining manageable complexity through algorithmic control
3Reliability
If motion stabilization is implemented, then unintended touches are reduced, but processing time increases
Solution Approach 1:
The system performs preliminary motion detection and preemptively adjusts touch zones before erroneous touches occur, preventing unintended inputs while maintaining efficient processing through advance preparation

AI summary
Embodiments of the present disclosure provide techniques for motion stabilized touch control. Reference data comprising one or more stabilized positions for one or more touch points corresponding to one or more touch zones associated with a touch screen device may be generated using a motion stabilization model. One or more touch zones may be adjusted based on the stabilized positions by transmitting-computer executable-instructions configured to cause the one or more touch zones to be aligned with the one or more stabilized positions. One or more touch detection models associated with the touch screen device may be updated by tuning the one or more touch detection models to learn the stabilized positions. One or more dimensions of the one or more touch zones may be recalibrated by adjusting a size of at least one of the one or more touch zones.
