Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens in high-motion environments, such as vehicles or cockpits, suffer from inaccuracy, latency, jittering touch points, unintended touches, and reduced usability due to motion-induced instability, leading to potential safety issues and operational challenges.
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 seamless user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch screens are used in high-motion environments, then user interaction is enabled, but touch accuracy deteriorates due to motion-induced instability
Solution Approach 1:
The system performs preliminary actions by detecting motion events and pre-adjusting touch zone positions before actual touch input occurs. The motion stabilization model predicts and compensates for motion-induced drift, establishing stabilized positions in advance to maintain touch accuracy during high-motion environments.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring touch input accuracy and comparing it against expected values. When motion-induced deviations are detected, the system adjusts touch zone positions and reprocesses touch detection logic to correct the deviation, ensuring accurate touch recognition despite ongoing motion.
2Measurement precision
If motion stabilization is implemented, then touch accuracy is improved, but device complexity increases
Solution Approach 1:
The motion stabilization model serves multiple functions simultaneously: it stabilizes touch zones, normalizes touch input, compensates for motion drift, and maintains consistent user interaction experience. By making the stabilization system multi-functional, the patent reduces the need for separate complex subsystems, thereby managing overall device complexity while improving touch accuracy.
Solution Approach 2:
The system manages complexity by dynamically changing parameters such as touch zone positions, detection thresholds, and normalization factors based on detected motion conditions. Rather than using fixed complex structures, the system adapts parameters in real-time, simplifying the overall architecture while maintaining high touch accuracy under varying motion conditions.
3Reliability
If touch zones are adjusted for motion stabilization, then unintended touches are reduced, but processing time increases
Solution Approach 1:
The system implements periodic action by processing touch zones at specific intervals triggered by motion detection rather than continuously. The motion stabilization model activates touch zone adjustment and reprocessing only when motion events are detected, reducing unnecessary processing time while maintaining high reliability during actual motion conditions.
Solution Approach 2:
The system performs preliminary stabilization actions when motion is detected, establishing stable touch zones in advance before user interaction occurs. This pre-adjustment reduces the need for continuous real-time processing during normal operation, thereby reducing processing time while maintaining touch reliability during high-motion environments.

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.
