Touch Control Method Distinguishing Normal Operation from Misoperation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch-control technologies often misinterpret user interactions due to careless touches on large screen interfaces, leading to unavoidable misoperations, as all touch events are considered normal operations without differentiation.
Innovation Solution
A method and apparatus that determine whether a user's observation area overlaps with their touch area, using a sample library to match user interface and interaction information, and only respond to touch instructions if the touch area and gesture match a corresponding sample, thereby distinguishing normal operations from misoperations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all touch events are considered normal operations, then the terminal device responds to all user inputs, but misoperations triggered by careless touches cannot be avoided
Solution Approach 1:
The patent segments touch events into different types by analyzing the relationship between touch area and observation area. It divides touch events into valid operations (when touch area overlaps with observation area) and misoperations (when no overlap occurs), allowing differential handling of different touch event types to improve operation accuracy while maintaining touch sensitivity.
Solution Approach 2:
The patent introduces an intermediary judgment mechanism that analyzes the spatial relationship between touch area and observation area before executing the touch response. This intermediary layer acts as a filter to distinguish intentional touches from accidental ones, resolving the contradiction between responding to all inputs and avoiding misoperations.
2Adaptability or versatility
If the touchscreen size is increased to save screen space and provide diversified interfaces, then more functions are available, but the user is more likely to touch the screen carelessly
Solution Approach 1:
The patent converts the harmful effect of larger screen size (increased misoperation rate) into a beneficial detection opportunity. By using the larger screen's spatial information to analyze the relationship between touch area and observation area, the system can identify and filter misoperations, thereby maintaining interface diversity while reducing accidental touches.
3Productivity
If the terminal device responds to all touch instructions, then user operations are processed quickly, but intentional operations cannot be distinguished from unintentional ones
Solution Approach 1:
The patent performs preliminary analysis of the touch event by determining the relationship between touch area and observation area before processing the operation. This preliminary action identifies valid touches that warrant response, filtering out misoperations in advance, thereby maintaining processing speed for genuine operations while improving intention recognition accuracy.
