Display Object Visibility During Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control devices suffer from reduced object visibility when widgets are scrolled off-screen, making it difficult for users to access and view them.
Innovation Solution
A display control device and program that includes an operation reception unit, area updating unit, and object updating unit, which changes the shape or size of objects to ensure they fit within the visible area during scrolling, preventing visibility reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If widgets are scrolled in the off-screen direction, then the scrolling function is improved, but object visibility is reduced
Solution Approach 1:
The widget dynamically changes its shape or size based on its position relative to the visible area. When a widget is detected to extend beyond the visible area during scrolling, the system automatically adjusts its dimensions to fit within the visible area, ensuring continuous visibility while maintaining scrolling functionality.
Solution Approach 2:
The system changes the shape or size parameters of widgets based on their position in the virtual space. By detecting whether a widget extends beyond the visible area and adjusting its shape/size parameters accordingly, the system maintains widget visibility during scrolling operations without compromising the scrolling function.
2Loss of information
If the shape or size of objects is changed to fit within the visible area, then object visibility is maintained, but device complexity increases
Solution Approach 1:
The widget automatically adjusts its own shape or size based on its position relative to the visible area. The system detects when a widget extends beyond the visible area and autonomously modifies its dimensions, eliminating the need for complex manual control logic and reducing overall device complexity.
Solution Approach 2:
The system continuously monitors the position of widgets in the virtual space and provides feedback when a widget extends beyond the visible area. This feedback triggers automatic shape or size adjustments, creating a closed-loop control system that maintains visibility without requiring complex predetermined control logic.

AI summary
In a screen on which a portion of objects among a plurality of objects arranged in a virtual space are displayed, reduction in object visibility by a user can be suppressed even when an object is scrolled in an off-screen direction. The operation reception unit receives scrolling operations on a screen in which a portion of the objects among a plurality of objects arranged in a virtual space are displayed. The area updating unit updates an area within the virtual space displayed on the screen in response to a scroll amount received by the operation reception unit. The object updating unit changes at least either an object shape or size when, in an area updated by the area updating unit, there is an object partially outside this area, so that the object fits within this area.
