Touch Panel Display Scroll Tap Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phones often misinterpret a flick operation as a tap operation when the finger is released without sufficient lateral movement, leading to accidental execution of intended actions on objects during screen scrolling, making it difficult for users to smoothly navigate to their desired screen position.
Innovation Solution
The electronic device incorporates a processor that detects and differentiates between flick and tap operations by setting a reception suppression flag during scrolling, disabling unintended tap operations on objects within the scroll region and indicating the disabled state through a distinct display style.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system allows tap operations during screen scrolling, then users can interact with objects on the screen, but accidental tap operations may be executed when users intend to scroll
Solution Approach 1:
The system dynamically changes the operational state of objects during scrolling. When scrolling is detected, the system temporarily disables tap operations on objects within the scroll region, and restores them when scrolling stops. This dynamic adjustment resolves the contradiction by adapting the interaction behavior to the current user intent context.
Solution Approach 2:
The system changes the operational parameter of objects from 'tap-enabled' to 'tap-disabled' during scrolling operations. This parameter change prevents accidental interactions while maintaining the ability to interact when needed, thus resolving the contradiction between scrolling smoothness and operation accuracy.
2Reliability
If the system disables tap operations during scrolling, then accidental operations are prevented, but users cannot intentionally tap objects during scroll
Solution Approach 1:
The system dynamically adjusts operation flexibility based on scrolling state. During active scrolling, tap operations are disabled to ensure accuracy. When scrolling stops, the system automatically restores tap functionality, allowing users to interact with objects when intended. This dynamic adaptation resolves the contradiction between reliability and flexibility.
Solution Approach 2:
The system periodically checks the scrolling state and adjusts operation permissions accordingly. Tap operations are enabled during non-scrolling periods and disabled during scrolling periods, creating a periodic pattern that balances reliability and flexibility based on user intent.
3Measurement precision
If the system suppresses tap operations during flick-based scrolling, then navigation accuracy is improved, but the interface responsiveness may be reduced
Solution Approach 1:
The system performs preliminary detection of flick operations and proactively disables tap operations before accidental taps can occur. By anticipating the user's scrolling intent and pre-adjusting the operational state, the system maintains both scroll position accuracy and interface responsiveness without conflict.

AI summary
A mobile phone includes a display, a touch detector configured to detect an operation at least including a flick operation and a tap operation, and a processor configured to execute the control program to execute processing in accordance with the operation. The processor can cause a screen displayed on the display to be scrolled based on the flick operation on a display region R included in the display. If the screen includes an object to be subjected to the tap operation and while the screen is being scrolled, the processor can disable the tap operation on the object.
