Input Control Device for Overlapping Operation Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple operation regions are expanded based on user habits and errors, there is a possibility of overlap, leading to decreased recognition accuracy and unintended function execution in input apparatuses.
Innovation Solution
An input control device that includes an operation detection unit to identify operations in overlap regions and an operation region control unit to select one expanded operation region based on priority conditions, ensuring that only one operation region receives the input operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation regions are expanded based on user habits and errors, then operability is improved, but recognition accuracy deteriorates when expanded regions overlap
Solution Approach 1:
The patent segments the display region into multiple operation regions, each associated with specific objects. When expansion occurs, the system further segments the overlap areas by detecting touch position and assigning operations to specific operation regions based on the touch location, thereby maintaining recognition accuracy while preserving expanded operability.
Solution Approach 2:
The patent applies local quality by differentiating the handling of non-overlap regions versus overlap regions. In non-overlap regions, the expanded operation region receives operations uniformly. In overlap regions, the system applies differentiated control by detecting touch position and assigning operations to specific operation regions, thus maintaining accurate operation recognition while preserving the benefits of expansion.
2Ease of operation
If multiple expanded operation regions overlap, then user-friendly operation is enhanced, but unintended function execution increases
Solution Approach 1:
The patent performs preliminary action by pre-defining operation regions and their associated objects before user interaction. When a touch occurs in an overlap region, the system has pre-established the mapping between operation regions and objects, allowing it to immediately and accurately determine the intended operation based on touch position without requiring additional user input or causing unintended functions.
3Adaptability or versatility
If operation correction values are applied to expand operation regions, then habit compatibility is improved, but operation region ambiguity increases
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of an operation region control unit that mediates between the expanded operation regions and the operation execution. This intermediary detects touch positions, determines which operation region should receive the operation based on pre-defined mappings, and routes the operation accordingly, thereby managing the complexity of multiple overlapping expanded regions systematically.

AI summary
A plurality of operation regions configured to receive an operation and a plurality of expanded operation regions that are expanded in association with the plurality of operation regions are provided in a display region of a display device. An input control device includes an operation detection unit configured to detect the operation that is input to an overlap region where a part of each of the plurality of expanded operation regions overlaps each other, and an operation region control unit configured to select one expanded operation region that receives the operation out of the plurality of expanded operation regions having the overlap region, based on a predetermined priority condition, and control the plurality of expanded operation regions such that, of the plurality of operation regions, one operation region corresponding to the one expanded operation region receives the operation.
