Display Device Swipe Discrimination in Turbulent Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices in aircraft cockpits struggle to accurately distinguish between deliberate and involuntary swipes on touch-sensitive interfaces, leading to unsatisfactory interactions with critical data.
Innovation Solution
A display device linked to a touch-sensitive surface, featuring an acquisition module to detect user interactions and a determining module that differentiates between taps and swipes based on distance and direction, determining operations such as selection or scrolling based on predefined thresholds, including a threshold angle for swipe direction relative to scrolling direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device uses a touch-sensitive surface to detect user interactions, then the ease of operation is improved, but the reliability of interaction detection deteriorates in turbulent environments
Solution Approach 1:
The patent changes multiple parameters of the tactile interaction to improve discrimination accuracy: it measures both the distance traveled during the interaction and the angle relative to scrolling direction. By analyzing these parameter combinations, the system can reliably distinguish between deliberate and involuntary swipes even in turbulent cockpit environments
Solution Approach 2:
The system implements feedback by using the determined operation (scrolling vs. selection) to confirm whether the detected tactile interaction was intentional. The angle threshold mechanism provides feedback validation - when the swipe angle exceeds the threshold relative to scrolling direction, the system interprets this as a deliberate selection gesture rather than an involuntary scroll
2Measurement precision
If the display device discriminates between tap and swipe based on interaction span, then the measurement precision is improved, but the reliability of discrimination deteriorates in turbulent environments
Solution Approach 1:
The patent transitions from one-dimensional discrimination (only based on interaction span/distance) to two-dimensional discrimination by introducing the angle dimension. The determining module now evaluates both the distance traveled and the angle relative to scrolling direction, creating a more robust discrimination mechanism that reliably distinguishes deliberate from involuntary interactions
3Ease of operation
If the display device interprets all swipes from non-selectable zones as scrolling operations, then the ease of operation is improved, but the measurement precision of user intent deteriorates
Solution Approach 1:
The patent changes the decision parameter from solely distance-based to a combined distance-and-angle-based criterion. By measuring the angle of the swipe relative to the scrolling direction and comparing it against a threshold, the system achieves precise measurement of user intent while maintaining ease of operation through natural gesture patterns

AI summary
An electronic device for displaying data on a display screen is able to be linked to a touch-sensitive surface and to the display screen. The display device comprises an acquisition module configured to acquire at least one tactile interaction by a user, detected by the touch-sensitive surface, and a determining module configured to determine a display operation as a function of the acquired tactile interaction.When the tactile interaction is a tap on a selectable zone or a swipe between a first selectable zone and a second selectable zone, then the determined operation is a selection operation of the corresponding selectable zone.When the tactile interaction is a swipe from a non-selectable zone, then the determined operation depends on the direction of the swipe.
