Terminal False Touch Prevention via Parameter Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices with touch screens often experience accidental operations due to unintended touches, leading to unwanted actions such as dialing, deleting messages, or turning on the camera, causing user inconvenience.
Innovation Solution
Implementing a method where the terminal detects touch operations and obtains touch parameters like press force value and duration to determine if they match preset criteria, thereby determining if the operation is invalid and responding accordingly to prevent accidental triggering of functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the touch screen is made responsive to all touches, then the terminal can respond to user operations quickly, but accidental operations will occur causing misuse
Solution Approach 1:
The patent changes the parameters of touch detection by analyzing multiple attributes including touch duration, touch area, pressure distribution, and touch pattern. By evaluating these parameters against predefined criteria, the system distinguishes between intentional user operations and accidental touches, maintaining quick response for valid inputs while filtering out false touches.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring touch parameters and comparing them against expected patterns for valid operations. When a touch matches the characteristics of intentional user input, the system responds immediately; when it matches accidental touch patterns, the system suppresses the response, thereby resolving the contradiction between speed and accuracy.
2Measurement precision
If the touch detection sensitivity is increased to detect all touches, then user operations can be detected accurately, but false touches will trigger unwanted actions
Solution Approach 1:
The patent employs multiple touch parameters including touch duration, contact area size, pressure distribution patterns, and touch sequence analysis. By setting threshold values and pattern recognition rules for these parameters, the system achieves high detection precision for intentional touches while automatically filtering out false touches that do not meet the established criteria.
Solution Approach 2:
The system introduces an intermediary processing layer between touch detection and action execution. This intermediary analyzes touch parameters and determines whether the touch represents a valid user operation before triggering any terminal functions. This mediation prevents false touches from causing unwanted actions while maintaining accurate detection of legitimate inputs.
3Ease of operation
If the terminal responds to all touch operations, then user convenience is maintained, but accidental operations cause user trouble
Solution Approach 1:
The system monitors multiple touch parameters such as duration, area, pressure, and movement patterns to distinguish between intentional user operations and accidental touches. By analyzing these parameters, the terminal maintains ease of operation for valid inputs while preventing accidental operations from causing harmful effects or user trouble.
Solution Approach 2:
The patent converts the potentially harmful effect of false touches into a benefit by using the characteristics of accidental touches (such as brief duration, small area, or inconsistent patterns) as identification criteria. By recognizing these patterns, the system filters out false touches while maintaining responsiveness to legitimate user operations, thus turning a problem into a solution.
Data Source
AI summary
A method for preventing false touches on a terminal and a terminal includes: a touch operation on a touch screen of a terminal is detected and a touch parameter of the touch operation is obtained. If the touch parameter matches a preset touch parameter, it is determined that the touch operation is an invalid operation, and the touch operation will be responded nothing.
