Palm Touch Gesture Privacy Control for Large Touch Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As electronic devices with larger touch screens display private or sensitive information, there is a risk of privacy invasion and personal information leakage, as the current systems do not effectively protect against accidental exposure of such information during usage.
Innovation Solution
Implementing a method that detects a palm touch while performing a primary function, allowing the device to switch to a secondary function that secures privacy, such as blurring or muting sensitive content, setting a lock screen, or changing the sound output mode, thereby preventing unintended exposure of personal data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the touch screen size is increased to provide better multimedia services and user interface, then the display quality and user experience are improved, but the risk of private information leakage increases due to larger display area
Solution Approach 1:
The system performs preliminary detection of palm touch gestures before sensitive information is displayed or during its display. The processor detects palm touch patterns in advance and proactively switches to privacy protection mode, preventing information leakage before it can occur. This is evident in the detection of palm touch gestures that trigger privacy protection functions.
Solution Approach 2:
The palm touch gesture serves as an intermediary signal between the user and the privacy protection mechanism. When the user places their palm on the screen, this gesture acts as a mediator that triggers the system to switch between normal display mode and privacy protection mode, effectively controlling information visibility without direct manual intervention.
2Loss of information
If the electronic device displays personal information on a large screen, then the information visibility is improved, but the security against accidental exposure deteriorates
Solution Approach 1:
The display system dynamically adjusts its behavior based on detected gestures. The processor continuously monitors touch patterns and switches between normal display mode and privacy protection mode in real-time. This dynamic adaptation allows the system to maintain high information visibility when needed while providing immediate security protection when a palm touch gesture is detected.
Solution Approach 2:
The system changes display parameters dynamically based on gesture detection. When a palm touch is detected, the processor modifies display settings to activate privacy protection functions such as blurring or masking sensitive information. This parameter change allows the same display hardware to serve both high-visibility and secure-display purposes.
3Adaptability or versatility
If the system provides multiple multimedia functions, then the versatility and user capability are improved, but the complexity of controlling privacy protection increases
Solution Approach 1:
The palm touch gesture serves as a universal control mechanism across multiple multimedia functions. Whether the device is displaying messages, browsing the web, or viewing photos, the same palm touch gesture triggers privacy protection. This universal gesture-based control simplifies the user interface while maintaining protection across diverse multimedia applications.
Solution Approach 2:
The system provides automatic privacy protection without requiring users to manually configure complex settings for each application. The processor automatically detects palm touch gestures and activates appropriate privacy protection measures based on the current context, making the system self-regulating and reducing the burden of complex privacy management on users.

AI summary
A method for operating of an electronic device is provided. The method includes detecting a palm touch on a touch screen of the electronic device while performing a first function of the electronic device, and performing a second function of the electronic device based on the detected palm touch on the touch screen of the electronic device.
