Document Scale and Position Optimization for Portable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in accurately scrolling or scaling documents on portable devices to view intended content, especially when content has different optimal scales and positions, leading to suboptimal viewing experiences.
Innovation Solution
A computer-implemented method and system that optimizes document scale and position in response to user input by identifying relevant content and adjusting the display to an optimal scale and position, providing visual feedback, and restraining further input requests within a threshold to maintain optimal viewing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the document is scaled to fit all content within the viewport, then the complete content becomes visible, but the reading quality deteriorates due to very small text size
Solution Approach 1:
The patent segments the document into multiple sections or regions, each with its own optimal viewing scale. Instead of forcing the entire document to one scale, the system divides content into manageable portions that can be independently optimized for display, allowing users to view different sections at appropriate magnification levels.
Solution Approach 2:
The patent introduces an additional dimension of control by allowing users to specify both position and scale parameters independently. This transforms the traditional single-scale viewing into a multi-dimensional viewing space where users can navigate to specific regions and adjust scale locally, resolving the conflict between showing all content and maintaining readability.
2Adaptability or versatility
If manual scrolling is used to navigate to specific content, then the user can access any part of the document, but the process becomes time-consuming and difficult to perform accurately
Solution Approach 1:
The patent implements preliminary action by allowing users to specify a target position before finalizing the scroll operation. The system pre-calculates the optimal scale and position for the requested content region, and provides visual feedback during the scrolling process to guide the user to the correct location, eliminating the need for trial-and-error manual scrolling.
Solution Approach 2:
The patent incorporates continuous visual feedback during the scrolling operation, showing users their current position relative to the target content. This feedback mechanism allows users to make real-time adjustments and ensures accurate navigation to the intended section, significantly reducing navigation time and improving accessibility.
3Adaptability or versatility
If the document is scrolled to display content at different optimal scales, then each content type can be viewed at its ideal magnification, but coordinating multiple scales and positions becomes complex
Solution Approach 1:
The patent merges the control of scale and position into a unified operation. Instead of requiring users to independently adjust scale and position for each content type, the system combines these controls into a single coordinated action, automatically managing the relationship between different content regions and their optimal display parameters.
Solution Approach 2:
The patent introduces an intermediary layer that automatically manages the coordination between multiple content scales and positions. This intermediary system handles the complex calculations and adjustments required to display different content types at their optimal scales, shielding users from the underlying complexity while maintaining full adaptability.

AI summary
Methods for optimizing a scale and position of a document in response to a user input is provided are provided. In one aspect, a method includes receiving an initial input request to scroll a document to a target position of the document, and identifying at least one relevant portion of content at or near the target position of the document. The method also includes adjusting a position and scale of the document while receiving the initial input request to an optimal position and an optimal scale for viewing the at least one relevant portion. Systems and machine-readable media are also provided.
