Steering Operation Input Control for Adjacent Touch Misactivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation control devices often inadvertently cancel intended operations due to the high probability of unintended actions when performing consecutive operations on push and touch switches, leading to user dissatisfaction.
Innovation Solution
An operation control device with a processor that limits process execution on a second operation region until a predetermined condition is met when an operation is performed in the direction of the second region from a first operation region, thereby reducing unintended operation execution and preventing intended operations from being canceled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation device limits execution of processes for touch switch operations after detecting a push switch operation, then unintended operations are reduced, but intended operations may be mistakenly canceled
Solution Approach 1:
The patent applies local quality by differentiating the treatment of adjacent operation regions based on the direction of the initial operation. When a push operation is detected, the system selectively limits touch operations only in the adjacent region in the direction of the push, while allowing touch operations in other regions to proceed normally. This localized approach reduces unintended operations without mistakenly canceling intended operations in other areas.
Solution Approach 2:
Instead of completely disabling touch operations after a push operation (which would cancel intended operations), the patent inverts the approach by selectively enabling touch operations only in regions not adjacent to the push direction. This inverted logic allows the system to maintain reliability by blocking likely unintended operations while preserving user convenience for legitimate touch inputs in other areas.
2Ease of operation
If the operation device accepts all touch operations after push operations, then user convenience is maintained, but unintended operations increase
Solution Approach 1:
The patent implements local quality by applying different acceptance criteria to different operation regions. Touch operations in regions adjacent to the push direction are rejected, while touch operations in non-adjacent regions are accepted. This spatial differentiation allows the system to maintain high user convenience for legitimate operations while filtering out unintended operations in the vulnerable adjacent region.
Solution Approach 2:
The patent introduces an intermediary filtering mechanism that sits between the touch operation detection and the process execution. This intermediary layer analyzes the spatial relationship between the push operation and subsequent touch operations, and selectively blocks only those touch operations that are likely unintended (those in adjacent regions), while allowing other touch operations to pass through to normal execution.
3Reliability
If the operation device implements directional analysis of operations, then operation accuracy improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the operation regions into distinct categories: the first operation region (push switch), the second operation region (touch switch), and adjacent versus non-adjacent regions. This segmentation allows the control logic to systematically evaluate each operation type and region combination, improving operation accuracy through structured analysis while keeping the complexity manageable through clear regional boundaries.
Solution Approach 2:
The patent introduces a spatial dimension to the operation analysis by evaluating the directional relationship between push and touch operations. Instead of treating all operations uniformly, the system analyzes operations in terms of their spatial adjacency and directional orientation, adding a geometric dimension to the control logic that improves accuracy without requiring complex temporal or contextual analysis.

AI summary
An operation control device includes a memory; and a processor connected to the memory, the processor being configured to: in a case in which the processor receives, at an operation unit that includes a first operation region and a second operation region adjacent to the first operation region, an operation performed on the first operation region in a direction of the second operation region, limit execution of processes corresponding to operations performed on the second operation region until a predetermined condition is met.
