Touchscreen Input Correction for Mobile Platform Perturbations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Perturbations during the operation of mobile platforms, such as changes in vehicle speed or position, can lead to user input errors on touchscreen display devices, causing accidental selections or failures in inputting commands.
Innovation Solution
A system and method that utilize sensor data from a mobile platform to detect and characterize perturbations, and then process user input data to determine if it is likely to be invalid due to the perturbation. The system initiates corrective actions, such as confirming, invalidating, or modifying user input, to mitigate errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touchscreen display devices are used in mobile platforms, then information access and interaction capability are improved, but user input errors occur due to perturbations during operation
Solution Approach 1:
The system performs preliminary detection of perturbations using sensor data before finalizing user input processing. By detecting perturbances in advance and characterizing their nature, the system can prepare appropriate corrective actions, ensuring that input validation and correction mechanisms are ready before erroneous inputs are processed, thus preventing unreliable inputs from affecting system operation
Solution Approach 2:
The system continuously monitors sensor data to detect perturbations and uses this feedback to dynamically adjust user input validation. When perturbations are detected, the system feeds this information back into the input processing pipeline to trigger corrective actions such as confirming, invalidating, or modifying user inputs, thereby maintaining input accuracy despite ongoing perturbations
2Reliability
If sensor data processing is added to detect perturbances, then user input error mitigation is improved, but system complexity increases
Solution Approach 1:
The system uses existing sensor components of the mobile platform for multiple purposes: their primary functions for vehicle operation monitoring and additionally for detecting perturbations that affect touchscreen input. By making existing sensors multi-functional, the system avoids adding dedicated hardware for perturbation detection, thereby reducing the increase in system complexity while still improving input reliability
Solution Approach 2:
The system leverages the mobile platform's own sensor data to detect and characterize perturbations affecting its touchscreen interface. Rather than requiring external monitoring systems, the platform uses its inherent sensing capabilities to self-diagnose perturbation conditions and trigger appropriate input correction mechanisms, reducing the need for additional complex external systems

AI summary
Systems and methods are provided for mitigating user input errors due to perturbances of mobile platforms. The systems may include, one or more sensors configured to sense measurable conditions internal or external to a mobile platform, and a controller in operable communication with the sensors and with a touchscreen display. The controller may be configured to, by one or more processors: receive sensor data from the sensors, process the sensor data to detect and characterize a perturbance, receive user input data indicative of user input performed by a user via the touchscreen display, process the user input data to determine whether the user input is likely to be invalid due to the perturbance, and initiate a corrective action in response to a determination that the user input is likely to be invalid due to the perturbance.
