Dynamic Operation Start Region for Touch Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch interface systems struggle to distinguish between normal swiping and edge swiping operations effectively, leading to confusion and reduced operability, especially when the operation start region is not clearly defined.
Innovation Solution
An information processing apparatus that includes a position detection unit, a region determination unit, and a reception unit to detect touch positions and determine the operation start region based on the operation status and display state, allowing for clear differentiation between swiping and edge swiping by adjusting the size and position of the operation start region dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operation start region is set larger to facilitate edge swiping, then ease of operation is improved, but the precision of distinguishing between normal swiping and edge swiping deteriorates
Solution Approach 1:
The patent dynamically changes the parameter of operation start region size based on display state. When the display shows content that benefits from edge swiping (such as list views or scrollable content), the operation start region is expanded. When the display state suggests normal swiping is more likely, the region is reduced. This parameter adaptation resolves the contradiction by making the region size context-dependent rather than fixed.
Solution Approach 2:
The operation start region is implemented as a dynamic rather than static element. The region determination unit continuously adjusts the operation start region based on real-time display state information, including the type of content being displayed, scroll position, and application context. This dynamic adjustment allows the system to optimize for edge swiping when appropriate while maintaining accurate distinction between operation types.
2Measurement precision
If the operation start region is set smaller to improve distinction between swiping operations, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system changes the operation start region parameter based on display state analysis. When the display shows content types where normal swiping is more common (such as image viewing or detailed content), the operation start region is reduced to improve distinction precision. When the display shows content types where edge swiping is beneficial (such as lists or feeds), the region is expanded to improve ease of operation.
3Device complexity
If a fixed operation start region is used, then device complexity is reduced, but adaptability to different display states deteriorates
Solution Approach 1:
The patent implements a dynamic operation start region that automatically adapts to different display states through programmatic control. The region determination unit monitors display state parameters (content type, scroll position, application context) and adjusts the operation start region accordingly. This dynamic approach provides high adaptability while maintaining relatively simple device architecture, as the adjustment is achieved through software logic rather than hardware complexity.
Solution Approach 2:
The system changes the operation start region parameter based on detected display state conditions. Different display states (such as list view versus image view, or different scroll positions) trigger different region configurations. This parameter adaptation enables the system to handle diverse content types and user scenarios without requiring complex hardware modifications.

AI summary
An information processing apparatus includes a touch sensor configured to detect a touch position on an input surface touched with a pointer. The information processing apparatus is configured to receive, depending on whether or not a linear locus of the touch position on the input surface starts from inside an operation start region set on the input surface, the linear locus of the touch position as any one of a first operation and a second operation different from the first operation on an image that is displayed on a predetermined display. The operation start region is determined based on at least one of an operation status of the pointer and a display state of the image.
