On-screen Element Visibility Control in Overlapping Display Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for displaying important information on-screen, such as using a subordinate display area, can fail to show all important on-screen elements when they scroll out of the main display area, leading to elements being hidden or displayed in both areas simultaneously.
Innovation Solution
An information processing apparatus with element identification and display control means that identifies on-screen elements entering or leaving the main display area and determines their inclusion in a subordinate display area, ensuring continuous visibility of important elements by overlapping the subordinate display area with the main area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a subordinate display area is used to display important on-screen elements that scroll out of the main display area, then important information remains visible, but some important elements may still be hidden or duplicated in both areas
Solution Approach 1:
The system continuously monitors the position of on-screen elements relative to the main display area during scrolling, and dynamically adjusts the subordinate display area content based on this feedback. When an important element scrolls out of the main display area, the system detects this change and responds by displaying it in the subordinate area, ensuring continuous visibility without duplication
Solution Approach 2:
The subordinate display area is not static but dynamically updated based on the scrolling state and position of important elements. The system adapts the content of the subordinate display area in real-time, adding elements that scroll out and removing elements that scroll back into the main display area, making the display system flexible and responsive to user interaction

AI summary
There is provided an information processing apparatus which makes it easier to avoid a condition in which the viewing of on-screen elements included in a web page is interfered with.An information processing apparatus displays a main display area that represents content of a web page on a screen of a display device. The information processing apparatus identifies, among a plurality of on-screen elements of interest, an on-screen element of interest that enters or departs from the main display area as the web page is scrolled along a given scrolling direction, when the web page that includes the plurality of on-screen elements of interest and that can be scrolled along the given scrolling direction appears in the main display area. The information processing apparatus also determines whether or not to include the identified on-screen element of interest as a target to be displayed in a subordinate display area that appears at a position overlapping the main display area in response to the entry or departure of the identified on-screen element of interest into or from the main display area.
