Dynamic Page Navigation for Scrollable Item Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable devices face inefficiencies when browsing numerous items, requiring multiple scroll operations or page navigations to find desired information, which impairs user experience due to fixed page sizes and limited user control over displayed content.
Innovation Solution
A method for generating display data that allows users to dynamically specify the number of pages displayed based on the distance between points in a scroll region, enabling adaptive page navigation and improved user experience by adjusting the number of items shown according to user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the number of items displayed per page is fixed, then the device structure is simple, but the user experience deteriorates when browsing numerous items requiring multiple scroll operations
Solution Approach 1:
The patent implements dynamic page size adjustment by allowing users to specify the number of items to display per page. The system calculates the number of pages based on the distance between two points in the display region, transforming the fixed page structure into a flexible one that adapts to user needs, thereby improving ease of operation without significantly increasing device complexity
Solution Approach 2:
The patent changes the parameter of page size from a fixed value to a variable that can be adjusted based on user input. By accepting two points in the display region and calculating the number of pages based on the distance between these points, the system dynamically modifies the display parameters to enhance user experience while maintaining reasonable system complexity
2Loss of time
If users must scroll through many pages to find desired information, then the display structure is simple, but the time required to find information increases
Solution Approach 1:
The patent allows users to pre-specify the number of items to display per page before browsing begins. By calculating and setting the page size in advance based on the user's indicated distance in the display region, the system prepares the optimal view configuration beforehand, reducing the time needed to find information while keeping operation complexity manageable
Solution Approach 2:
The patent replaces the traditional mechanical scrolling mechanism with a calculated page navigation system. Instead of relying on sequential scrolling through fixed pages, the system uses distance-based calculations to determine page boundaries and allows users to jump directly to desired sections, significantly reducing information search time while maintaining operational simplicity
Data Source
AI summary
A display data generation method used in a computer including an output module, includes generating display data of page numbers for scrollably displaying page numbers of a plurality of pages each containing predetermined item information, to output the display data of page numbers from the output module, retrieving page information indicating a same number of pages as a number of page numbers displayed in a distance corresponding to a distance between two points in a display region in which the page numbers are displayed when the two points are specified by the user, wherein the number of page numbers are calculated based on the distance between the two points and the distance between adjacent page numbers displayed in the display region, and generating item display data for displaying item information contained in the pages indicated in the retrieved page information, to output the item display data from the output module.
