Scroll Tracking for User Interest Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to determine which content a user is interested in among multiple contents on a web page, as they primarily rely on browsing time, which does not accurately reflect interest in specific displayed areas.
Innovation Solution
An information processing apparatus and method that tracks scroll operations on a user terminal, obtaining and storing information about content display changes, scroll lengths, and content identification data to determine user interest by analyzing these metrics, and presents related content to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If browsing time is used to determine user interest, then the implementation is simple, but the measurement precision of user interest in specific content is low
Solution Approach 1:
The patent segments the web page into multiple display areas and tracks scroll operations to identify which specific segments the user views. By dividing the page content into distinct regions and monitoring scroll behavior within these regions, the system can precisely determine user interest in specific content segments rather than treating the entire page as a single unit.
Solution Approach 2:
The patent adds a spatial dimension to user interest measurement by incorporating scroll position and display area coordinates. Instead of only measuring time duration, the system now measures both temporal aspects (how long) and spatial aspects (where on the page), creating a two-dimensional measurement approach that significantly improves precision.
2Measurement precision
If scroll operation tracking is implemented to determine user interest in specific content, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The terminal device automatically generates and transmits scroll operation information without requiring additional manual input from the user. The system leverages existing scroll events that occur naturally during normal browsing, processing this information automatically to determine user interest. This approach minimizes additional complexity while maintaining high measurement precision.
Solution Approach 2:
The patent makes the terminal device perform multiple functions: it not only displays web content but also automatically tracks scroll operations, processes position information, and generates interest determination data. By integrating these functions into a single system, the patent reduces overall device complexity compared to having separate specialized components for each function.
3Measurement precision
If detailed scroll information is collected and stored for each content, then the user interest determination accuracy improves, but the loss of time for data processing increases
Solution Approach 1:
The patent extracts only the essential scroll operation information needed for interest determination, such as scroll position, display area coordinates, and scroll direction. Instead of collecting and processing all possible browsing data, the system selectively extracts the most relevant parameters, significantly reducing data processing time while maintaining high determination accuracy.
Solution Approach 2:
The system performs preliminary processing of scroll information by organizing and storing it in a structured format during the browsing session. This preliminary organization of data during natural browsing activities reduces the computational burden during the actual interest determination phase, as the data is already prepared and categorized for quick analysis.

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.
