Display Control for Scroll Boundary Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for displaying multiple element objects on a screen, such as search results or file names, fail to clearly indicate when the beginning or end object is displayed, leading to increased memory usage with large background images to convey this information.
Innovation Solution
An information processing device and method that includes a display unit, a first scrolling unit, and a determination unit to scroll and manage the display of element objects, determining whether to scroll in a second direction based on the position of the display area and the element objects, allowing the user to recognize the beginning or end object without increasing memory size by restricting the movement and displaying the background image only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a large background image is displayed above the beginning element object to indicate the start of the list, then the user can immediately recognize the beginning object, but the memory size increases
Solution Approach 1:
The patent extracts the essential visual indicator from a large background image and implements it as a separate, minimal border line above the beginning element object. This border line conveys the same information (start of list) without requiring the large background image, thus reducing memory usage while maintaining the recognition function.
Solution Approach 2:
Instead of using a large background image that covers the entire screen, the patent applies a localized border line only at the specific position where the beginning element object is displayed. This localized approach provides the necessary visual indication precisely where needed without the overhead of a large image file.
2Ease of operation
If the display object is scrolled to show the beginning element object, then the user can see the first item, but the user cannot immediately recognize it as the beginning object without scrolling further
Solution Approach 1:
The patent uses visual changes (border lines) to indicate the beginning and end of the element object list. These visual markers allow users to immediately recognize the beginning object without needing to scroll further to verify, improving both ease of operation and information retention.
3Ease of operation
If the display object is scrolled to show the end element object, then the user can see the last item, but the user cannot immediately recognize it as the end object without scrolling further
Solution Approach 1:
The patent uses visual markers (border lines) to indicate the end of the element object list, allowing users to immediately recognize when they have reached the end object without needing to scroll further to verify, improving ease of operation and preventing information loss.

AI summary
An information processing device for allowing a user to immediately understand that a beginning or end element object is displayed on a screen is provided. The device includes a display unit for displaying a portion of a display object, in which a plurality of element objects are arranged, in a display area, a first scrolling unit for scrolling the display object in a first direction in response to an operation of a user, a second scrolling unit for scrolling the display object in a second direction that is opposite to the first direction, and a determination unit for determining whether or not to scroll the display object in the second direction based on a position of the display area and a position corresponding to the plurality of element objects.
