Touch Panel Misrecognition Detection via Back Operation Frequency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch panels in electronic devices may malfunction, leading to misrecognition of user operations and rendering operation assist functions ineffective.
Innovation Solution
An electronic apparatus with a display device and a panel control unit that detects frequent user operations to go back along screen transitions, triggering the display of a misrecognition key to indicate potential touch panel malfunction, and offering a help function to assist the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch panel continuously monitors user operations to provide operation assist, then the help function becomes more responsive, but the system complexity increases
Solution Approach 1:
The panel control unit performs preliminary actions by monitoring the frequency of back operations in advance and proactively displaying the misrecognition indication before the user realizes the touch panel malfunction. This early detection and notification approach improves operation assist responsiveness without requiring complex real-time analysis during each operation.
Solution Approach 2:
The system implements feedback by continuously monitoring the frequency of back operations and using this information to determine when to display the misrecognition indication. This feedback mechanism allows the operation assist function to adapt to user behavior patterns and provide timely help without excessive system complexity.
2Speed
If the touch panel operates at high frequency to respond to user input, then the operation speed improves, but the likelihood of misrecognition increases
Solution Approach 1:
The panel control unit uses feedback from monitoring back operation frequency to detect touch panel misrecognition. By analyzing the frequency pattern of back operations, the system can identify when the touch panel is malfunctioning and display appropriate indications, thereby maintaining high operation speed while improving reliability through intelligent monitoring.
Solution Approach 2:
The system performs preliminary monitoring of operation patterns to detect potential misrecognition before it affects the user experience. By establishing a baseline of normal operation frequency and comparing current operations against this baseline, the system can early detect anomalies and provide assistance without slowing down normal high-speed operations.

AI summary
An electronic apparatus includes a display device, a touch panel, and a panel control unit. The display device is configured to display an operation screen. The touch panel is configured to detect an operation to the operation screen. The panel control unit is configured to perform transition of the operation screen in accordance with the detected operation. Further, if the operation to go back along the transition is detected with a predetermined frequency or more, the panel control unit displays on the operation screen a first soft key to indicate misrecognition of the touch panel.
