Dynamic Touch Menu Region Adjustment for Accidental Input Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch display panels in electronic devices are sensitive to accidental touches, leading to undesired control commands when users hold the device, making it uncomfortable to navigate due to the need to position thumbs away from functional options.
Innovation Solution
An electronic device with a touch display panel featuring a panel touch control unit that adjusts the size of the touch menu region and content display region based on touch signal duration and area, preventing accidental command execution by adjusting the screen layout dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a touch display panel is used to provide both input and display functions, then the space and cost for disposing a conventional keyboard is saved, but the device becomes very sensitive to accidental touches when users hold it
Solution Approach 1:
The patent applies dynamics by making the touch menu region dynamically adjustable in size and position. The control unit receives touch signals and determines whether to enlarge the touch menu region based on the touch coordinates, allowing the interface to adapt its behavior according to user interaction patterns rather than maintaining a fixed configuration
Solution Approach 2:
The patent applies local quality by creating different functional regions with different properties on the touch display panel. The touch menu region has distinct characteristics from the content display region, with the ability to be selectively enlarged or positioned in specific areas to provide different interaction modes in different parts of the screen
2Reliability
If users position their thumbs away from functional options to avoid accidental touches, then accidental control commands are prevented, but the operation becomes very uncomfortable
Solution Approach 1:
The system dynamically adjusts the touch menu region size based on touch signals. When a touch is detected, the control unit can enlarge the touch menu region to provide larger, more comfortable target areas for subsequent interactions, eliminating the need for users to precisely position their thumbs away from functional options
Solution Approach 2:
The system performs preliminary action by proactively enlarging the touch menu region in response to a touch signal, preparing the interface for comfortable continued interaction. This preliminary enlargement prevents the need for users to maintain awkward thumb positions during operation
3Ease of operation
If the touch menu region size is increased to improve accessibility, then ease of operation is improved, but the content display region size is reduced
Solution Approach 1:
The patent applies dynamics by making the boundary between touch menu region and content display region dynamically adjustable. The control unit can shift this boundary to enlarge the touch menu region when needed for accessibility, and restore it when content display is prioritized, allowing the system to adapt to different usage scenarios
Solution Approach 2:
The patent applies another dimension by utilizing the spatial dimension of the display panel more flexibly. The touch menu region can be positioned and sized in different areas of the screen, and the content display region can be adjusted accordingly, allowing both regions to coexist with optimized sizes based on interaction needs rather than fixed allocations
