Touch Screen Object Adjustment for Turbulence Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screens in aircraft environments face challenges due to parallax distortion and movement caused by turbulence, G forces, and vibrations, which affect the accuracy and ease of data input for flight crew, as existing solutions do not adequately adapt to these conditions.
Innovation Solution
A touch screen system that adjusts the positioning and size of touch sensing objects based on the position and frequency of touches, using circuitry and a controller to modify the boundaries of the objects in response to user input, thereby improving accuracy and reducing the impact of environmental interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If touch panel size and resolution are increased, then display quality and information density improve, but touch accuracy deteriorates due to parallax distortion and movement from turbulence, G forces, and vibrations
Solution Approach 1:
The patent implements dynamic adjustment of touch object parameters (position, size, shape) based on detected movement and turbulence conditions. The system continuously monitors accelerometer data and adjusts touch sensitivity parameters in real-time, transforming static touch objects into dynamic ones that adapt to environmental conditions, thereby resolving the contradiction between display quality and touch accuracy
Solution Approach 2:
The system changes physical parameters of touch objects (position coordinates, boundary dimensions, sensitivity thresholds) in response to detected environmental conditions. By modifying these parameters dynamically, the system maintains touch accuracy despite variations in display quality and environmental disturbances
2Productivity
If touch objects are made smaller to increase information density, then productivity improves, but ease of operation deteriorates due to difficulty in accurate touching during movement
Solution Approach 1:
The patent makes touch objects dynamically adjustable in size and position based on detected turbulence and movement conditions. During calm conditions, objects maintain smaller sizes for high information density. During turbulence, the system automatically enlarges touch objects and adjusts their positions, allowing the system to achieve both high productivity and ease of operation under different conditions
Solution Approach 2:
The system uses accelerometer feedback to detect movement and turbulence conditions, then adjusts touch object parameters accordingly. This closed-loop feedback mechanism allows the system to respond to environmental changes in real-time, maintaining ease of operation while preserving information density
3Device complexity
If fixed touch object positions are used, then device complexity is reduced, but adaptability deteriorates in response to environmental movement and turbulence
Solution Approach 1:
The patent implements a self-adjusting system where the touch screen automatically detects environmental conditions through integrated sensors and adjusts its own parameters without external intervention. The system monitors accelerometer data and autonomously modifies touch object positions and sizes, providing adaptability while maintaining relatively simple device architecture through self-service functionality

AI summary
A touch screen and method are provided for adjusting the positioning of touch sensing objects in response to the position of the application of one or more touches. The touch screen, includes, but is not limited to a display face including an object, the display face configured to display a symbol associated with the object, and circuitry defining the object and configured to sense the position of at least one touch on at least a portion of the object. A touch screen controller is configured to adjust the object in response to the position of the at least one touch.
