Display Control Apparatus for Overlapping Content Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems fail to accurately scroll content when multiple items overlap, leading to unintended scrolling and reduced usability.
Innovation Solution
A display control program that differentiates between modes for interacting with content within specific regions on a screen, allowing precise control over scrolling and display changes based on user input, ensuring only intended content is scrolled or modified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drag operation is detected on a selected scroll target region, then the target image displayed in the scroll target region is scrolled, but when multiple contents overlap within the selected region, another content may be scrolled instead of the intended content
Solution Approach 1:
The patent segments the scroll target region into multiple hierarchical levels: the overall scroll target region and nested sub-regions corresponding to individual contents. When a drag operation is detected, the system determines which sub-region the drag starts from and scrolls only that specific content, not the entire scroll target region. This segmentation resolves the contradiction by enabling precise control over which content is scrolled, preventing unintended scrolling of overlapping contents while maintaining ease of operation through natural drag gestures.
2Adaptability or versatility
If one scroll target region is selected from among multiple scroll target regions, then a drag operation can be performed, but it becomes difficult to perform intended operations on specific overlapping contents
Solution Approach 1:
The patent applies local quality by assigning different interaction properties to different sub-regions within the same scroll target region. Each content's display region is treated as a distinct sub-region with its own scrollability characteristics. The determination unit identifies which sub-region the user intends to interact with based on the drag start position, and only that sub-region responds to scrolling operations. This allows the system to maintain adaptability in handling multiple overlapping contents while improving ease of operation through intuitive, location-based control.

AI summary
A computer-readable storage medium having stored therein a program that is executed by a computer using a display section and an input section for designating a position on a screen of the display section. The program causes the computer to operate as: means for displaying at least a part of a first content and a second content such that a first region defined by the first content includes a second region for displaying the second content; means for determining, on the basis of a position designated by the input section, whether or not a criterion concerning the input is met; and means for switching between a first mode in which the input operation changes a display form of the first content, and a second mode in which the input operation changes a display form of the second content within the second region, depending on a result of the determination.
