Touch Operation Section State Switching for Unintended Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses with touch operation sections face challenges in preventing incorrect operations due to the proximity of the touch operation area to the user's hand, leading to unintended touches and reduced operability.
Innovation Solution
An electronic apparatus equipped with a processor that judges the type of touch operation and switches between a restricted state and a non-restricted state based on specific touch operations, allowing only certain operations to be effective in the restricted state to minimize incorrect inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch operation section is arranged on the side surface of the housing, then operability is improved by enabling operation with thumb while holding the device, but the risk of incorrect operations increases due to proximity to user's hand
Solution Approach 1:
The patent changes the operational parameters of the touch operation section by implementing different operational states (first state with restricted functions and second state with released restrictions). The processor judges the type of touch operation and switches between states accordingly, allowing normal touch operations in the second state while restricting them in the first state, thereby reducing incorrect operations while maintaining ease of operation
Solution Approach 2:
The patent makes the touch operation section dynamic by switching its functional state based on detected operation types. The system transitions between a first state where predetermined functions are restricted and a second state where they are released, allowing the touch operation section to adapt its behavior dynamically rather than maintaining a fixed operational mode
2Adaptability or versatility
If multiple touch operation types are supported, then functionality is improved, but the complexity of operation control increases
Solution Approach 1:
The patent segments the operational functions into two distinct categories: predetermined functions that can be restricted and other functions that remain available. By dividing the functional scope and applying different control rules to different function types, the system manages complexity while maintaining versatility
Solution Approach 2:
The processor continuously monitors and judges the type of touch operation performed, providing feedback that triggers state switching. This feedback mechanism allows the system to automatically adjust its operational state based on real-time input detection, managing complexity through automated response rather than user burden

AI summary
In order to achieve comfortable operations while appropriately preventing incorrect operations by unintentional touch operations on a touch operation section, when a touch operation performed on the touch operation section such as a selfie pad is a predetermined touch operation such as a double tap operation different from a touch operation such as a single tap or slide operation for giving an instruction to perform a predetermined function, switching is performed between a first state that is a selfie pad restricted state for restricting the predetermined function capable of being performed by the touch operation on the selfie pad and a second state that is a selfie pad restriction released state for releasing the restriction of the predetermined function.
