Electronic Device Misoperation Prevention via Grip-Based Operation Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses face malfunctions due to misoperations, particularly when the orientation is falsely detected or when a palm accidentally contacts a touch panel during operation, leading to unintended switching and operational disruptions.
Innovation Solution
An electronic device with distinct operation members for each grip position, where the system control unit prioritizes responses based on specific grip configurations, ensuring that only intended operations are executed when both operation members are activated, thereby ignoring unintended touch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If orientation-based switching is used to prevent misoperations on multiple touch panels, then misoperation prevention is improved, but false detection occurs when the device faces directly downward or upward
Solution Approach 1:
The invention divides the operation members into two distinct groups: a first operation member operable by the thumb of the hand holding the first grip portion, and a second operation member operable by the thumb of the hand holding the second grip portion. This segmentation allows the system to differentiate between intentional operations on the first operation member and unintentional operations on the second operation member, resolving the orientation detection accuracy issue while maintaining misoperation prevention.
Solution Approach 2:
The invention applies different operational rules to different parts of the device. The first operation member responds to operations under all conditions, while the second operation member is selectively responsive based on grip detection. This local differentiation in operational quality allows the system to maintain high reliability without suffering from false orientation detection.
2Ease of operation
If multiple operation members are provided for different grip positions, then ease of operation is improved, but misoperations increase when palm accidentally contacts operation members
Solution Approach 1:
The invention dynamically adjusts the responsiveness of operation members based on detected grip state. When the grip state indicates the user is holding the device by the first grip portion, the first operation member remains fully responsive while the second operation member becomes unresponsive. This dynamic adjustment maintains ease of operation for intentional inputs while preventing misoperations from accidental palm contact.
Solution Approach 2:
The grip state detection unit continuously monitors the grip position and provides feedback to the control unit, which then adjusts the operational status of the second operation member accordingly. This feedback mechanism ensures that only operations on the first operation member are processed when the grip state corresponds to the first grip portion, effectively filtering out accidental contacts while preserving intentional operations.

AI summary
An electronic device includes: a first operation member; a second operation member; and at least one memory and at least one processor which function as: a control unit configured to perform control so as to execute a predetermined function in accordance with an operation to the first operation member and to execute the predetermined function in accordance with an operation to the second operation member, and, in a case where operations to both the first operation member and the second operation member are made, to execute the predetermined function in accordance with the operation to the first operation member without responding to the operation to the second operation member.
