Dynamic Touch Activation Region Adjustment for Moving Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting touch inputs on touch-sensitive displays are ineffective, particularly when the display is moving, leading to increased cognitive burden and reduced efficiency, especially in vehicles where this can impact safety.
Innovation Solution
The method involves adjusting touch activation regions on a touch-sensitive display based on the movement of the display, ensuring that touch inputs are detected within the adjusted area to perform associated user interface operations accurately and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the touch-sensitive display is moving (e.g., inside vehicles), then the device can be used in more environments, but the touch input detection becomes ineffective
Solution Approach 1:
The system performs preliminary actions by detecting movement of the touch-sensitive display and proactively adjusting the touch activation regions before touch input occurs. The processor detects movement, determines new activation regions, and updates the display accordingly, ensuring that when the user touches the display, the correct region is already prepared and highlighted, maintaining reliable detection despite the display being in motion.
2Device complexity
If the touch activation region is fixed, then the system is simple to implement, but the user interface efficiency decreases when the display moves
Solution Approach 1:
The system transitions from a static, fixed touch activation region to a dynamic, adjustable region. The processor continuously monitors the position of the touch-sensitive display, detects movement, and dynamically adjusts the activation region accordingly. This dynamic adaptation maintains user interface efficiency while adding manageable complexity through automated detection and adjustment mechanisms.
3Measurement precision
If the touch activation region is adjusted frequently, then the touch input detection accuracy improves, but the power consumption increases
Solution Approach 1:
The system employs periodic action by detecting movement at specific intervals rather than continuously adjusting. The processor monitors for movement events and only adjusts the activation region when movement is detected, rather than performing constant adjustments. This periodic approach maintains detection accuracy while significantly reducing power consumption compared to continuous adjustment.

AI summary
A device displays a first selectable user interface (UI) element associated with a first touch activation region. The device detects a change of movement of the display. In response to the change of movement, the device adjusts the first touch activation region to encompass a new area. The new area is at least partially different from the first touch activation region prior to the change of movement and is based on the change of the movement. After detecting the change of movement, the device detects a touch input. In accordance with a determination that the touch input is detected within the adjusted first touch activation region, the device performs a user interface operation associated with the first selectable UI element. In accordance with a determination that the touch input is detected outside the adjusted first touch activation region, the device forgoes performance of the user interface operation.
