Scroll Area Tracking for Content Interest Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to accurately determine which content a user is interested in among multiple contents on a web page, as they rely solely on browsing time, which does not account for user engagement with specific display areas.
Innovation Solution
An information processing apparatus that obtains and stores information related to content display changes and identification information during user scroll operations, allowing for the determination of user interest by analyzing scroll change amounts, display area lengths, and overlap of content areas before and after scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If browsing time is used to determine user interest, then the determination process is simple, but it cannot identify which specific content the user is interested in
Solution Approach 1:
The patent segments the web page into multiple display areas (e.g., first display area, second display area) and tracks scrolling behavior within each segment. By dividing the page content into manageable sections and monitoring which segments remain visible during scrolling, the system can identify specific content areas that attract user attention, thereby achieving content-level interest identification without overly complex processing.
2Measurement precision
If detailed scroll behavior tracking is implemented to identify interested content, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent extracts only the essential scrolling behavior data needed for interest determination, such as the position of display areas before and after scrolling, and the amount of scrolling. Instead of tracking all possible user interactions, the system focuses on extracting key parameters (display area positions, scroll distance) that directly indicate user interest, thereby maintaining measurement precision while reducing system complexity.
Solution Approach 2:
The patent uses the concept of copying display area information before and after scrolling operations. By creating simplified representations (copies) of the display area states at different scroll positions, the system can compare these copies to determine which content areas received attention, achieving accurate content-level tracking without requiring complex real-time analysis of the entire page.
3Measurement precision
If multiple display areas are monitored to determine user interest, then measurement precision improves, but loss of information increases due to data volume
Solution Approach 1:
The patent applies local quality by focusing analysis on specific display areas rather than treating the entire web page uniformly. Each display area is monitored independently for scrolling behavior, and interest determination is performed locally for each content segment. This approach improves measurement precision for specific content while reducing the overall data processing burden by avoiding global analysis of the entire page.

AI summary
Content is displayed in an active display region of a terminal apparatus, and information relating to the display of said content when the content scrolls in accordance with a scrolling operation performed by a user and content identifying information for identifying the content are obtained from the terminal apparatus and it is determined whether or not the user of the terminal apparatus is interested in the content identified by the content identifying information that is extracted in accordance with the information relating to the display of the content.
