Solution Overview
Problem
Conventional methods for scrolling through content lists are inefficient, leading to user fatigue and increased power consumption, as users struggle to locate desired content and maintain focus while scrolling.
Innovation Solution
A display control device with units for identifying a base-point content, calculating positional differences, and scrolling to minimize these differences, allowing intuitive scrolling based on tension representation, thereby reducing user effort and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional scrolling methods are used to search through content lists, then users can browse contents, but users perform many operations which increases power consumption and device load
Solution Approach 1:
The system pre-calculates and stores the positional relationships between base-point contents and focus positions. When scrolling is initiated, the predetermined scrolling amount is immediately applied based on pre-computed tension values, eliminating the need for continuous real-time calculations during user interaction and reducing processing load and power consumption.
Solution Approach 2:
The patent creates a virtual copy of the physical scrolling interaction by calculating a hypothetical scrolling amount based on tension representation. Instead of requiring actual manual scrolling operations, the system computes an equivalent scrolling distance that would result from a natural pulling motion, allowing the content list to jump directly to the target position without iterative adjustments.
2Loss of information
If users manually scroll through content lists to locate desired content, then content can be found, but users experience fatigue from performing many operations
Solution Approach 1:
The system continuously monitors the positional relationship between base-point contents and the focus position, calculating tension values that provide visual feedback to users. This feedback mechanism allows users to intuitively understand the scrolling dynamics and target position without needing to manually explore each content item, reducing search effort while maintaining accurate position tracking.
Solution Approach 2:
The scrolling system automatically adjusts the content list position based on the calculated tension between base-point contents and focus position. Instead of requiring users to manually scroll and search, the system performs the scrolling action itself by computing the appropriate scrolling amount and executing the position change, making the search process autonomous and effortless.
3Measurement precision
If precise tracking of base-point content position is maintained during scrolling, then focus position accuracy is improved, but computational complexity increases
Solution Approach 1:
The system pre-calculates and stores tension values and scrolling amounts for various base-point content positions before actual scrolling operations occur. This preliminary computation allows the system to maintain high position tracking accuracy during scrolling by simply retrieving pre-computed values rather than performing complex real-time calculations, significantly reducing computational load during user interaction.
Solution Approach 2:
The patent implements a dynamic scrolling model where the scrolling amount is determined by the calculated tension between base-point contents and focus position. This dynamic approach allows the system to adapt the scrolling behavior to the specific positional relationship, maintaining precision while simplifying the control logic through physics-based metaphors that naturally handle edge cases and boundary conditions.
