Overlay Command Area for Limited Display Scroll Bottleneck
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses with limited screen size, such as smartphones and tablets, face difficulties in displaying command areas for setting items due to the need for frequent scrolling, which complicates user operation when there are many setting items.
Innovation Solution
A display apparatus that generates a first image with a setting area and a command area, and upon user operation, displays a second image representing the command area even if the original command area is not visible within the display area, allowing seamless user interaction without requiring constant scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display area size is limited, then the device portability is improved, but the command area cannot be displayed without frequent scrolling
Solution Approach 1:
The patent applies dimensionality change by displaying the command area in a popup window that overlays the setting area, transitioning from a linear one-dimensional layout to a two-dimensional layered layout. This allows both the setting area and command area to be simultaneously accessible without requiring vertical scrolling, effectively resolving the contradiction between limited display area and ease of operation.
2Loss of information
If the command area is displayed separately, then the setting area visibility is improved, but the user cannot confirm settings without additional navigation
Solution Approach 1:
The patent merges the command area and setting area into a single integrated popup window structure. The command area is positioned adjacent to the setting area within the same overlay, allowing users to both view setting information and execute confirmation operations without navigating between separate screens or menus, thus reducing navigation complexity while maintaining visibility.

AI summary
A display apparatus includes a processor. The processor is configured to: generate a first image including (i) a setting area for receiving a setting of a setting item and (ii) a command area for receiving a command regarding the setting; generate a second image representing the command area; receive an operation on the setting item performed by a user; and display the second image over the first image in a case where the command area is not displayed when the processor receives the operation.
