Electronic Device Diagonal Input Detection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices fail to accurately recognize and prevent unintentional diagonal inputs, leading to unintended operations when users press keys unintentionally, particularly during scrolling operations, resulting in user intention mismatch.
Innovation Solution
An electronic device with a detection unit configured to differentiate between first and second direction operations, executing specific processing modes based on simultaneous or non-simultaneous detection of these operations, and continuously executing processing in certain modes to prevent unintended diagonal inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If diagonal direction input recognition is enabled, then input versatility is improved, but unintentional operations occur when users accidentally press adjacent keys
Solution Approach 1:
The patent implements dynamic switching between two operation modes: a first operation mode where diagonal direction inputs are recognized, and a second operation mode where diagonal direction inputs are not recognized. The system transitions between these modes based on detected input patterns, allowing versatile input recognition when needed while preventing unintentional operations when accidental presses occur
Solution Approach 2:
The patent changes the operational parameter of diagonal input recognition by switching between two distinct operation modes. In the first mode, diagonal inputs are enabled for versatile control; in the second mode, diagonal inputs are disabled to prevent erroneous operations. This parameter change allows the system to adapt its input recognition behavior based on the operational context
2Productivity
If simultaneous pressing of multiple keys is recognized as diagonal input, then input efficiency is improved, but user intention mismatch occurs during scrolling operations
Solution Approach 1:
The patent uses feedback from the detection unit to determine whether simultaneous key presses represent intentional diagonal inputs or unintentional accidental presses. The control unit monitors input patterns and provides feedback by switching between operation modes, ensuring that diagonal input recognition enhances productivity only when it aligns with user intention
3Speed
If key repeat function is enabled for continuous pressing, then operational speed is improved, but unintentional diagonal inputs are triggered during horizontal scrolling
Solution Approach 1:
The patent dynamically adjusts the operation mode based on the scrolling direction and input pattern. When horizontal scrolling is detected, the system switches to the second operation mode where diagonal inputs are not recognized, preventing unintentional diagonal movements. When vertical scrolling or other operations are performed, the system switches to the first operation mode to enable diagonal input recognition, thus maintaining operational speed without triggering harmful unintentional inputs

AI summary
An electronic device includes a control unit configured to perform control, in a first operation mode, to execute first processing in a case where a first detection unit, which is for detecting an operation indicating a first direction, detects an operation, to execute second processing in a case where the second detection unit, which is for detecting an operation indicating a second direction, detects an operation, and to execute third processing in a case where the second detection unit further detects an operation, and in a second operation mode, to execute fourth processing in a case where the first detection unit detects an operation, to execute fifth processing in a case where the second detection unit detects an operation, and to continuously execute the fourth processing in a case where the second detection unit further detects an operation.
