Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users find it difficult to continuously pay attention to specific content information on web pages, especially when it scrolls out of the display area, due to existing techniques that fail to effectively highlight or re-display important information.

Innovation Solution

An information processing device and method that specifies attention content information and displays a copy of it on the screen when it is about to be scrolled out, using techniques such as residual images or moving copies to maintain user focus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If content information is displayed on a web page and the user scrolls the page, then the user can access more content information, but the content information moves out of the display area and becomes difficult to notice

Engineering Contradiction:

Improvecontent information accessibilityVSAvoidcontent information detectability

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent creates a copy of the content information (residual image) that remains on the display screen after the original content scrolls out of view. This copy is generated by detecting when content information is about to leave the display area and rendering a residual image at the previous position, allowing users to continue noticing the content without scrolling back.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system performs preliminary action by detecting the moment when content information is about to move out of the display area and proactively generating a residual image before the content completely disappears. This preliminary generation of the copy ensures continuous visibility and prevents the content from being lost to the user.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the character string is framed out by scrolling, then the user can access new content, but the character string is not displayed again until the scroll direction is reversed

Engineering Contradiction:

Improvecontent information flowVSAvoidcontent information re-display time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements a copying mechanism where the content information is duplicated as a residual image that remains permanently on the display screen. This eliminates the need for the user to scroll back to see the content again, as the copy persists until manually removed or until new content overlays it.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The residual image mechanism ensures continuous visibility of content information by maintaining the copy on the display screen throughout the scrolling process. The content remains accessible and noticeable continuously, rather than disappearing and requiring re-display after scrolling reverses.

Inventive Principle:

Principle #20Continuity of useful action

3Difficulty of detecting and measuring

If a technique is applied to highlight map elements when scrolling, then the user can determine content presence at a glance, but the technique cannot cause the user to pay attention to character strings framed out by scrolling

Engineering Contradiction:

Improvecontent information detectabilityVSAvoiduser attention maintenance

Core Design Contradiction:

Difficulty of detecting and measuringVSEase of operation

Solution Approach 1:

The patent extends the highlighting technique by creating a persistent copy (residual image) of the content information that remains on the display screen after scrolling. This copy maintains the visual emphasis and continues to attract user attention, solving the problem of framed-out content becoming invisible.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The system performs preliminary action by generating the residual image before the content completely leaves the display area. This ensures that the content remains highlighted and noticeable throughout the scrolling action, maintaining user attention on important information without requiring the user to reverse scrolling direction.

Inventive Principle:

Principle #10Preliminary action

AI summary

Provided are a device and a method which facilitate continued focusing of a user on specific content information even when said specific content information has been moved off the display screen by scrolling or page transitioning. Focus content information, which is identified from content information displayed on the display screen of the terminal device, is set in advance as content information for user focus. Then, in response to user operations which transition said focus content information out of the display area, copy content information, being a copy of said focus content information, is displayed for a certain period of time on the display screen of said terminal device.
