Touch Operation State Switching with Variable Time Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch operation systems for electronic devices face issues with poor operability due to insufficient feedback and the inability for users to recognize the current state of the touch operation, leading to accidental switching between restricted and enabled states, and unintentional execution of functions.
Innovation Solution
An electronic device with a control unit and switching mechanism that uses a first touch operation with a specific continuation time to switch from a restricted state to an enabled state and a second touch operation with a longer continuation time to switch back to the restricted state, providing better operability and user recognition of touch operation status.

Engineering Contradiction Analysis
1Ease of operation
If a double tap operation is used to switch between restricted and enabled states, then the switching operation is simplified, but the operability difference between switching from restricted to enabled and from enabled to restricted is not considered
Solution Approach 1:
The patent applies different touch continuation time thresholds for different switching directions: a first threshold for switching from restricted to enabled state, and a second threshold for switching from enabled to restricted state. This local differentiation of operational parameters prevents unintentional switching while maintaining ease of operation for legitimate user actions.
Solution Approach 2:
The patent changes the touch continuation time parameter based on the current state and desired transition direction. By setting different time thresholds (first threshold vs. second threshold) for different state transitions, the system distinguishes between intentional and unintentional touch operations, thereby preventing accidental state changes.
2Speed
If the touch continuation time for switching from restricted to enabled state is short, then the switching speed is improved, but the risk of accidental switching increases
Solution Approach 1:
The patent implements different touch continuation time requirements for different switching directions. A shorter first threshold enables quick activation from restricted to enabled state when needed, while a longer second threshold prevents accidental deactivation from enabled to restricted state, thus balancing speed and error prevention.
Solution Approach 2:
The patent applies a longer touch continuation time requirement as a preliminary protective measure when switching from enabled to restricted state. This extended time threshold acts as a preventive mechanism against accidental switching, requiring deliberate user intention before disabling the touch operation function.
3Device complexity
If feedback display about current state is not provided, then the device interface remains simple, but user recognition of touch operation status deteriorates
Solution Approach 1:
The patent introduces feedback mechanisms that display the current state of the touch operation member to the user. This feedback allows users to recognize whether the touch operation is in restricted or enabled state, preventing confusion and unintentional operations while maintaining a relatively simple interface design.

AI summary
An electronic device includes: a control unit configured to control so as to execute a predetermined function in accordance with a predetermined touch operation with respect to a touch operation member in a case where the touch operation member is in an enabled state, and not to execute the predetermined function in a case where the touch operation member is in a restricted state; and a switching unit configured to switch to the enabled state in accordance with a first touch operation with respect to the touch operation member in the restricted state, a touch continuation time of the first touch operation reaching a first time, and switch to the restricted state in accordance with a second touch operation with respect to the touch operation member in the enabled state, a touch continuation time of the second touch operation reaching a second time.
