Swipe-In Detection Region for Display Operation Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with operation panels, the swipe-in operation is not accurately detected when the edge of the operation screen region does not coincide with the physical edge of the panel, leading to recognition errors, especially in two-screen display scenarios where the user's intention is misinterpreted as a swipe operation.
Innovation Solution
A display device with an operation panel that employs a hardware processor to detect swipe-in operations using a swipe-in operation detection region provided near the edge of the operation screen region, allowing for selective execution of detecting operations based on first and second detection regions, which are adjusted when the operation screen region is displayed on a part of the panel, ensuring accurate recognition even when the edge does not coincide with the physical edge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the swipe-in operation detection is performed using a fixed detection region near the physical edge of the operation panel, then the swipe-in operation can be detected when the operation screen region coincides with the physical edge, but the detection accuracy deteriorates when the operation screen region does not coincide with the physical edge
Solution Approach 1:
The swipe-in operation detection region is made dynamic by adjusting its position and size based on the actual position of the operation screen region. The control unit determines the detection region by offsetting from the edge of the operation screen region by a predetermined distance, rather than using a fixed position relative to the physical panel edge. This allows the detection region to adapt to different display configurations including two-screen displays.
Solution Approach 2:
The detection region is positioned locally relative to the operation screen region rather than the physical panel edge. By setting the detection region at a predetermined offset distance from the edge of the operation screen region, the system ensures that the detection region is always in the appropriate location regardless of how the operation screen region is positioned on the panel.
2Quantity of substance
If the entire operation panel is divided into multiple operation screen regions, then more information can be displayed simultaneously, but the swipe-in operation may be misrecognized as a swipe operation
Solution Approach 1:
The operation panel is divided into multiple operation screen regions, with each region having its own dedicated swipe-in operation detection region. This segmentation ensures that swipe-in operations in different regions are independently detected and recognized, preventing misidentification between adjacent regions.
Solution Approach 2:
A predetermined offset distance acts as an intermediary buffer zone between the operation screen region and its detection region. This buffer ensures that the detection region does not overlap with adjacent operation screen regions, thereby preventing misrecognition of swipe-in operations as swipe operations across region boundaries.
3Device complexity
If the swipe-in operation detection region is positioned at the physical edge of the panel, then the detection structure is simple, but the detection fails when the operation screen region is positioned away from the physical edge
Solution Approach 1:
Instead of using a static detection region positioned at the physical panel edge, the system employs a dynamic detection region whose position is determined relative to the operation screen region. The control unit calculates the detection region position by offsetting from the operation screen region edge, allowing the detection region to automatically adjust to different screen positions without increasing hardware complexity.

AI summary
A display device includes: an operation panel that displays various types of information and accepts an operation input; and a hardware processor that: displays an operation screen region on an operation panel; and detects, using a swipe-in operation detection region in a vicinity of an edge of the operation screen region among a plurality of edges of the operation screen region, a swipe-in operation from the vicinity of the edge to an inner side of the operation screen region while continuing a touching state with the operation panel.
