Foreground Background Screen Layering for Rapid Home Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses take significant time to process and display the home screen, especially when clearing user operation information, which can lead to delays and inefficiencies in user transitions.
Innovation Solution
The apparatus employs a display control unit that overlays a foreground screen with a background home screen, allowing for rapid switching by predicting and pre-loading frequently used or last screens, thereby reducing the time required to display the home screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image forming apparatus clears user operation information and returns to home screen, then user privacy is protected, but display response time increases significantly
Solution Approach 1:
The system performs preliminary actions by generating and displaying a background home screen in advance before the clearing operation is triggered. When user operation information needs to be cleared, the pre-generated background home screen can be immediately switched to the foreground, significantly reducing the display response time while maintaining privacy protection
Solution Approach 2:
The system introduces a temporal dimension by creating foreground and background screen layers. The background home screen is generated in advance and stored, allowing the system to switch between foreground (user-specific) and background (default home) screens based on privacy requirements without requiring complete regeneration of the home screen
2Manufacturing precision
If the apparatus generates home screen from scratch each time, then screen content is always fresh and accurate, but processing time is excessive
Solution Approach 1:
The system generates the home screen structure and content in advance as a background screen before it is actually needed. This preliminary generation includes loading common applications, widgets, and layout elements, so that when switching is required, only the foreground/background layer needs to be swapped rather than regenerating the entire home screen
Solution Approach 2:
The system creates a copy of the home screen in the background layer that can be quickly switched to the foreground. This copied version maintains the essential structure and content accuracy while allowing for rapid deployment when privacy clearing is triggered

AI summary
An image forming apparatus for a display that is configured to display at least one of a foreground or a background includes a display control unit and a determining unit. The display control unit configured to cause the display to display, in the foreground, a first screen corresponding to a first input by a user. The display control unit is also configured to cause the display to display, in the background, a second screen corresponding to a home screen of the user. The display control unit is also configured to cause in response to receiving a clear input from the user, the display to display, in the foreground, the second screen and display, in the background, the second screen separately from the second screen displayed in the foreground. The determining unit is configured to determine a first duration that a third screen is displayed in the foreground.
