Mobile Terminal Touch Panel Sensitivity Control for Gloved Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication terminals face challenges in accurately determining the effectiveness of touch operations, particularly when users wear gloves, due to varying sensitivity settings of the touch panel, which can lead to unclear feedback on successful interactions with incoming call keys.
Innovation Solution
A mobile communication terminal with a touch panel that can set sensitivity levels high or low, coupled with a processor that displays objects on the screen and provides feedback through visual and haptic means, such as color changes and vibrations, to confirm effective touch operations, especially during incoming calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the touch panel sensitivity is set high to detect touch operations when users wear gloves, then the detection capability is improved, but false touch operations may occur due to accidental contacts
Solution Approach 1:
The system provides visual feedback by changing the display color of the touch target object and haptic feedback through vibration when a touch operation is detected. This feedback mechanism confirms to the user that their touch was successfully registered, allowing them to adjust their touching behavior to avoid false operations while maintaining high sensitivity for genuine touches.
Solution Approach 2:
The touch panel sensitivity is dynamically adjusted based on the detected touch state. When a touch operation is detected, the sensitivity is temporarily increased to ensure detection of gloved touches, and then returned to the normal state, creating a dynamic sensitivity adjustment that balances detection capability with false operation prevention.
2Reliability
If the touch panel sensitivity is set low to prevent false touch operations, then the false operation rate is reduced, but the ability to detect touch operations when users wear gloves is deteriorated
Solution Approach 1:
The system performs preliminary detection of touch operations and provides immediate visual and haptic feedback before the operation is fully executed. This allows users to correct their touch input if it was accidental, effectively preventing false operations while maintaining the ability to detect genuine touches.
Solution Approach 2:
Visual feedback through display color changes and haptic feedback through vibration provide immediate confirmation of touch detection. This feedback loop enables users to distinguish between successful touch operations and accidental contacts, improving reliability without sacrificing detection capability.
3Loss of information
If visual feedback is provided by changing display color to confirm effective touch operations, then user awareness of touch effectiveness is improved, but power consumption increases
Solution Approach 1:
The display color change feedback is applied periodically only when touch operations are detected, rather than continuously. The display returns to its normal state after providing feedback, creating a periodic action that provides necessary user information while minimizing power consumption compared to continuous high-power display states.
Data Source
AI summary
The touch panel is configured to be located on the display and have sensitivity to a touch operation being able to set relatively high or low. The at least one processor is configured to display an object on the display in response to an incoming call, configured to determine whether a touch operation on the object is effective, configured to determine whether a touch operation is performed in a state where the sensitivity of the touch panel is set relatively high, configured to give notice that a first touch operation on the object is effective when the at least one processor determines that the first touch operation is effective and the first touch operation is performed in the first state, and configured to execute a predetermined processing when a predetermined time has passed in a state where the first touch operation continues.
