Touch Region Adjustment for Accidental Touch Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often accidentally touch extended touch regions on electronic devices when grasping them, leading to unintended operations.
Innovation Solution
A touch region adjustment method that detects changes in sensing parameters, such as pressure and capacitance, to determine the user's grasp gesture and adjusts the touch region's location to avoid accidental touches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If extended touch regions are added to improve screen utilization, then screen utilization is improved, but accidental touches increase
Solution Approach 1:
The patent applies dynamics by making the touch region adjustable and movable based on detected grasp gestures. The touch region is not fixed but can be repositioned dynamically when a grasp gesture is detected, allowing the system to adapt between two states: extended coverage for productivity and repositioned coverage for preventing accidental touches during grasping
Solution Approach 2:
The patent changes the position parameter of the touch region based on detected grasp gestures. When a grasp gesture is detected, the system changes the position of the touch region to an adjusted position that avoids the user's hand, thereby preventing accidental touches while maintaining the ability to provide extended functionality when not grasped
2Adaptability or versatility
If touch region is extended to side regions, then interaction functionality is improved, but unintended operations increase
Solution Approach 1:
The system dynamically adjusts the touch region position based on the detected grasp gesture. When grasping is detected, the touch region moves to a safe position that prevents unintended operations while maintaining interaction functionality when the device is not being grasped
Solution Approach 2:
The system takes preliminary anti-action by detecting the grasp gesture before unintended operations can occur and preemptively repositioning the touch region to prevent accidental touches, rather than trying to correct unintended operations after they happen
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively reduces accidental touches and improves user experience by ensuring the touch region is positioned away from the grasp area, preventing unintended device operations.
Implementation Method 1
obtaining a first region on a touch display of a terminal device and in which a sensing parameter changes; the sensing parameter includes a pressure parameter
Implementation Method 2
the sensing parameter includes a capacitance parameter

AI summary
An embodiment of this application discloses a touch region adjustment method. The touch region adjustment method includes: determining a region on a touch display of a terminal device and in which a sensing parameter changes, to further determine a grasping gesture of a user for the terminal device; and then, adjusting a location of a touch response region on the touch display based on the grasping gesture of the user for the electronic device, to avoid an accidental touch caused by the grasping gesture of the user for the screen of the terminal device, thereby improving user experience.
