Mobile Terminal Application Control via Static Touch Area Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals are inconvenient to use for controlling applications, with complex operation procedures, especially when users need to stop multimedia functions like music playback in urgent situations.
Innovation Solution
An application-controlling method for mobile terminals that detects static actions on the touch screen, determines the touch area, and compares it with a threshold area to stop running applications, using an action-sensing chip and baseband signal processing chip to differentiate between static and point touches.

Engineering Contradiction Analysis
1Ease of operation
If conventional mobile terminals require users to return to control interface and manually operate buttons or click touch screen to stop applications, then the application control function is available, but the operation procedure is complex and inconvenient especially in urgent situations
Solution Approach 1:
The system performs preliminary detection of static actions (palm covering or face touching) on the touch screen before the user needs to stop the application. When a static action is detected, the system automatically determines the touch area and compares it with a threshold area to trigger automatic application stopping, eliminating the need for users to manually navigate to control interfaces.
Solution Approach 2:
The mobile terminal automatically detects user actions and controls application running states without requiring manual intervention. The system self-judges whether to stop applications based on detected static actions and threshold comparisons, making the terminal autonomous in application management.
2Measurement precision
If the touch screen detects any touch action to control applications, then application control is achieved, but it cannot distinguish between point touches and static covering actions leading to inaccurate control
Solution Approach 1:
The action detection process is segmented into distinct phases: detecting touch actions, determining action type (point touch vs. static action), calculating touch area for static actions, and comparing with threshold. This segmentation allows the system to handle different action types systematically without overwhelming complexity.
Solution Approach 2:
The system applies different detection criteria based on the local characteristics of touch actions. For point touches, simple coordinate detection is used. For static actions (palm covering or face touching), the system calculates touch area by detecting consecutive sensing channels and compares with threshold, applying localized quality analysis to distinguish action types.

AI summary
A mobile terminal and an application-controlling method thereof are provided. The application-controlling method for the mobile terminal according to the present disclosure comprises: detecting an action on a touch screen of the mobile terminal when an application is running; if the action is a static action, then acquiring a touch area between the static action and the touch screen; and comparing the touch area with a threshold area, and if the touch area is no less than the threshold area, then stopping running of the application. In this way, the mobile terminal and an application-controlling method thereof according to the present disclosure can make it more convenient for the user to operate the applications of the mobile terminal and are easy to operate and to be popularized.
