Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen, full-screen, and curved-screen touch devices experience high misoperation rates due to accidental touches at the edge regions when users hold the devices, leading to reduced touch detection accuracy.
Innovation Solution
A method and device that determine the application scene of a touch screen and identify accidental-touch prevention regions based on usage data and preset relations, shielding operations on these regions to prevent accidental touches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the touch screen uses large-screen, full-screen or curved-screen design, then the display area and visual effect are improved, but the misoperation rate increases due to accidental touches at edge regions
Solution Approach 1:
The patent applies different touch sensitivity characteristics to different regions of the touch screen. Specifically, the edge regions are configured with different touch detection properties compared to the central region, allowing the system to maintain high display area while reducing accidental touches at edges through localized quality differentiation.
Solution Approach 2:
The touch screen is divided into multiple regions including edge regions and central regions, with each region having independently configurable touch sensitivity. This segmentation allows the system to optimize touch detection separately for different areas, reducing misoperation at edges while preserving full-screen functionality.
2Reliability
If the edge regions are shielded to prevent accidental touches, then the misoperation rate is reduced, but the touch detection accuracy in those regions deteriorates
Solution Approach 1:
The patent implements dynamic region configuration where the edge regions can be dynamically adjusted or activated based on application scenarios. The system can switch between different touch sensitivity modes for edge regions, enabling them to be more sensitive when needed and less sensitive when accidental touches are likely, thus balancing detection accuracy and misoperation prevention.
Solution Approach 2:
The touch sensitivity parameters of edge regions are made adjustable and configurable. By changing parameters such as touch threshold, sensitivity level, or activation conditions for edge regions, the system can optimize performance for different usage scenarios, improving touch detection accuracy when needed while reducing accidental touches during holding operations.
