Tactile Input Classification for Aircraft Cockpit Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern aircraft cockpit displays often face challenges due to the limited viewable area and overlapping information, making it time-consuming and error-prone for pilots to select desired elements, as they need to pan and zoom to differentiate between elements.
Innovation Solution
The system identifies and classifies tactile user inputs based on temporal characteristics, such as short or long touches, to determine the intended selection among multiple graphical elements, using a prioritization scheme that considers the current operational context to automatically select the most relevant element.

Engineering Contradiction Analysis
1Quantity of substance
If multiple graphical elements are displayed in close proximity to provide comprehensive information, then the quantity of information is improved, but the ease of selection deteriorates due to overlapping and limited viewable area
Solution Approach 1:
The system changes the parameter of temporal duration to distinguish between different types of user interactions. Short touches (e.g., 0.5 seconds or less) are interpreted as selection attempts, while longer touches (e.g., greater than 0.5 seconds) are interpreted as confirmation or cancellation actions. This temporal parameter differentiation allows the system to handle ambiguous touch locations by using time-based classification to resolve selection intent among multiple overlapping graphical elements.
2Quantity of substance
If the display shows detailed information in a limited area, then the density of information is improved, but the time required for navigation and selection increases
Solution Approach 1:
The system performs self-service by automatically determining user intent based on the temporal characteristics of the touch input. Instead of requiring the user to manually pan, zoom, or navigate through multiple display screens to locate and select elements, the system uses the duration of the touch to automatically interpret whether the user intends to select, confirm, or cancel an action. This automated intent recognition reduces navigation time and eliminates the need for multiple manual operations to achieve selection among dense graphical elements.
3Productivity
If graphical elements are positioned in close proximity to maximize display capacity, then the productivity is improved, but the reliability of selection deteriorates due to increased error rate
Solution Approach 1:
The system changes the parameter of temporal duration to create a reliable selection mechanism even when graphical elements are densely packed. By establishing a clear temporal threshold (e.g., 0.5 seconds) that distinguishes selection attempts from other interactions, the system achieves reliable selection accuracy without requiring increased spacing between elements. This temporal parameter provides a robust criterion for disambiguating user intent among closely positioned graphical elements, thereby maintaining high display capacity while ensuring selection reliability.

AI summary
Methods and systems are provided for resolving a selected graphical element corresponding to a tactile user input associated with a graphical user interface display on a display device associated with a vehicle, such as an aircraft. The tactile user input is classified based on its temporal duration, and the classification of the tactile user input influences the identification of the selected graphical element or other response to the tactile user input.
