Display Processing Apparatus Scroll Reversal Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for scrolling and displaying information on a limited display device require extensive user effort to locate desired candidates, as they necessitate continuous scrolling and potential backtracking, leading to inefficiency and user frustration.
Innovation Solution
A display processing apparatus that includes a display device, a storage device, an input device, and a display control device, which allows for automatic reversal of the scroll direction by a predetermined amount when the desired information is missed, and increases scrolling speed when continuous input is detected, optimizing the retrieval of desired candidates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous scrolling is performed to locate desired conversion candidates, then the user can search through all candidates, but the time required increases significantly and user effort increases
Solution Approach 1:
The system performs preliminary scrolling in a predetermined direction to a predetermined position before the user's desired candidate appears. When the user stops inputting directional commands, the system automatically scrolls back a predetermined amount in the opposite direction, effectively preparing the display to show candidates near the user's likely target without requiring the user to manually scroll back.
Solution Approach 2:
The system monitors the user's directional input commands and dynamically adjusts the scroll position. When input terminates, the system calculates the current position and automatically reverses the scroll by a predetermined amount, providing feedback that helps the user quickly locate desired candidates without excessive manual scrolling.
2Area of stationary object
If the display range is limited and many conversion candidates exist, then the display device can show only a subset at a time, but the user must continuously scroll to find desired candidates
Solution Approach 1:
The system automatically performs preliminary scrolling actions in a predetermined direction to a predetermined position, then reverses the scroll by a predetermined amount when user input terminates. This eliminates the need for users to manually scroll through all candidates or backtrack manually, significantly reducing user effort while working within the limited display range.
3Speed
If the user scrolls past the desired candidate, then the user can quickly move through candidates, but the user must scroll back to find the desired candidate
Solution Approach 1:
The system performs preliminary scrolling in a predetermined direction to a predetermined position, then automatically reverses the scroll by a predetermined amount when user input terminates. This preliminary action ensures that when the user stops scrolling, the display shows candidates near the user's likely target, eliminating the need to scroll back manually and saving time.

AI summary
According to the display processing apparatus of the present invention, when an instruction to perform scrolling and displaying of information terminates, the information is returned by a predetermined scroll amount in the reverse direction of the scrolling and displaying direction. That is, although the user-desired information has passed the display range on the display device while scrolling, the information is returned by a predetermined amount. As a result, it is not necessary for the user to return all the way to the desired candidate.
