Touch Screen Region Segmentation for One-Hand Mis-Press Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience parsing errors when operating a mobile terminal with a touch screen held by one hand due to accidental palm contact, leading to mis-presses and incorrect operations, with existing solutions failing to provide effective solutions.
Innovation Solution
A method and device that set predetermined 'readily-mis-pressed' and 'non-readily-mis-pressed' regions on the touch screen, where the latter allows accurate operations during a timed period, distinguishing between intentional and accidental touches to prevent parsing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user operates the touch screen with one hand held terminal, then the operation convenience is improved, but the palm contact causes mis-presses and parsing errors
Solution Approach 1:
The touch screen is segmented into multiple operation regions (first operation region and second operation region) based on their susceptibility to mis-presses. The processing unit differentiates between these regions to apply different operation handling logic, allowing one-hand operation convenience while preventing palm-induced errors in sensitive regions
Solution Approach 2:
Different regions of the touch screen are assigned different operational characteristics. The first operation region (more prone to mis-presses) and second operation region (less prone) have distinct handling rules, with the system applying local quality differentiation to maintain both convenience and accuracy in respective regions
2Reliability
If the system implements strict operation recognition to avoid mis-presses, then the operation accuracy is improved, but the operation complexity increases
Solution Approach 1:
The operation processing is segmented into region-specific handling logic. The processing unit identifies which operation region is activated and applies corresponding processing rules, simplifying the overall complexity by dividing the problem into manageable regional segments rather than implementing complex global analysis
Solution Approach 2:
The system changes the parameter of region identification as a key differentiator. By detecting which operation region (first or second) is activated, the system adjusts its processing behavior accordingly, maintaining accuracy without requiring complex operation analysis across the entire screen

AI summary
The present application discloses a method and a device for operating a terminal having a touch screen, and the method includes steps of: starting to count a predetermined first time period when a predetermined condition is met; when an operation is performed by a user on a predetermined non-readily-mis-pressed region of the touch screen during the first time period, implementing the operation, otherwise implementing an operation performed by the user on a readily-mis-pressed region. The method and the device for operating a terminal having a touch screen provided by the disclosure solve the problem of error operations when a user holds the terminal by one hand and performs operations, thereby providing the user with conveniences.
