Display Data Generation for Scroll and Operation Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-functional peripherals (MFPs) and portable information devices, users face difficulties in performing screen position shifts when a scroll region occupies the entire display target region, leading to unintended scroll operations instead of screen position changes, complicating the operation procedure and losing gesture consistency.
Innovation Solution
A data generating device is implemented to partially display a screen with a scroll region, providing an operation region for screen position shifts by setting a target region, determining its size, and automatically adjusting the display to ensure the operation region is sufficient for user input, thereby preventing unintended scroll operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a scroll region occupies the entire display target region to maximize content display, then the area for displaying scrollable content is improved, but the ease of operation deteriorates because users cannot perform screen position shifts without triggering unintended scroll operations
Solution Approach 1:
The display target region is divided into two distinct areas: a scroll region for displaying scrollable content and an operation region for receiving screen position shift operations. This segmentation allows the scroll region to occupy maximum display area while the operation region provides a dedicated zone for unambiguous gesture input, resolving the contradiction between maximizing content display and maintaining ease of operation.
2Ease of operation
If the display target region is reduced to provide an operation region for screen position shifts, then the ease of operation is improved, but the area for displaying scrollable content deteriorates
Solution Approach 1:
Different regions of the display target region are assigned different functions with different qualities: the scroll region is optimized for content display with scrollable properties, while the operation region is optimized for gesture reception with screen position shift properties. This local differentiation allows each region to perform its specific function effectively without compromising the other.
3Ease of operation
If automatic display adjustment is implemented to ensure sufficient operation region, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The display data generating device performs preliminary actions by automatically adjusting the display target region position and size before user operation to ensure that an operation region of sufficient size is always available. This proactive adjustment prevents the need for complex real-time gesture interpretation and reduces operational errors, outweighing the moderate increase in display management complexity.

AI summary
A device for causing a display unit to partially display a screen having a scroll region in which a content is scrolled and an operation region is provided. The device includes: a setting portion that sets a target region which is a part of the screen displayed by the display unit; a change instructing portion that instructs the setting portion to change the target region based on operation on the operation region; a determination portion that judges, when the setting portion changes the target region, whether or not a size of the operation region of the target region is smaller than a set value; a display change portion that causes the setting portion to perform processing of increasing the operation region displayed by the display unit; and a generating portion that generates section screen data representing a content in the target region.
