Dynamic Touch Sensitive Region Adjustment for Overlapping UI Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple display items are closely positioned on a touch panel, it is difficult for users to accurately perform touch operations, leading to unintended functions being activated due to overlapping touch sensitive regions.
Innovation Solution
An electronic apparatus with a display control unit, detecting unit, setting unit, selecting unit, moving unit, and reception unit, which sets wider sensitive regions for each display item and moves touched items to ensure accurate touch operations by receiving touch inputs as intended, even when sensitive regions overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch sensitive regions are set in a wider area than display items to enable easier touching, then ease of operation is improved, but when multiple display items are displayed in close proximity, their touch sensitive regions overlap causing unreliable touch operation recognition
Solution Approach 1:
The touch sensitive region is dynamically adjusted based on the selected display item. When a display item is selected, its touch sensitive region is expanded to a wider area to facilitate easier touching. When not selected, the touch sensitive region is restricted to the exact display region. This dynamic adjustment resolves the contradiction by providing easy touching for the selected item while preventing overlap confusion for unselected items.
Solution Approach 2:
Different touch sensitive region sizes are applied to different display items based on their selection state. The selected display item has an expanded touch sensitive region, while unselected items maintain their original display region boundaries. This local differentiation allows the system to provide enhanced ease of operation for the active item without causing reliability issues with neighboring items.
2Productivity
If multiple display items are displayed in close proximity to maximize screen utilization, then productivity is improved, but accurate touch operation becomes difficult leading to unintended function activation
Solution Approach 1:
The system dynamically changes the touch sensitive region boundaries based on selection state. For the selected display item, the touch sensitive region expands beyond the display region to make touching easier. For unselected items, the touch sensitive region remains confined to the display region. This allows multiple items to be densely arranged on screen while ensuring accurate touch recognition for the intended target.
Solution Approach 2:
The selection state acts as an intermediary mechanism that mediates between the need for dense item arrangement and accurate touch recognition. By using visual selection indicators and corresponding touch sensitive region adjustments, the system enables users to accurately identify and touch the intended item even when items are closely positioned, thus maintaining both productivity and ease of operation.
3Ease of operation
If touch sensitive regions are expanded to wider areas to accommodate imprecise touch operations, then ease of operation is improved, but determination of which display item the user intends to operate becomes ambiguous
Solution Approach 1:
The touch sensitive region size is dynamically controlled based on the selection state of display items. When a display item is selected, its touch sensitive region is expanded to provide tolerance for imprecise touch. When not selected, the touch sensitive region is restricted to the exact display region boundaries. This dynamic control maintains clarity of user intent by ensuring that only the selected item has the expanded tolerance zone.
Solution Approach 2:
The system applies different touch sensitive region characteristics to different display items based on their selection state. The selected item receives the benefit of an expanded touch sensitive region for ease of operation, while unselected items maintain precise boundaries. This local quality differentiation prevents ambiguity in user intent by ensuring that expanded tolerance zones are only active for the currently intended target.

AI summary
There are provided a setting unit, a selecting unit, a moving unit, and a reception unit. The setting unit sets each of sensitive regions of a plurality of display items in a wider region than each of display regions of the plurality of display items. The selecting unit selects any of the plurality of display items. The moving unit moves a display item in accordance with a touch operation. The reception unit receives a touch operation as an operation to a display item having been selected when a touch operation to an overlapped region is detected. The overlapped region is a region in which the sensitive regions of the plurality of display items overlap.
