Hover-Based Address Switching on Compact Image Forming Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses with limited screen size cannot display all addresses for transmission functions on one screen, preventing users from checking multiple addresses without touching the screen.
Innovation Solution
An image forming apparatus that switches displayed addresses based on changes in coordinates of a moving object, such as a user's hand, without physical contact, allowing for scrolling and switching of addresses using hover operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the screen size is limited, then the device can be compact and portable, but it becomes impossible to display all transmission addresses on one screen
Solution Approach 1:
The patent implements dynamic display switching where the displayed address changes based on the detected hand position. As the user's hand moves across different regions of the screen, the system dynamically switches between multiple addresses, allowing all addresses to be accessed on a limited screen area without requiring a larger display.
Solution Approach 2:
The patent introduces hand position detection as an intermediary mechanism between the user and the address display. By detecting where the user positions their hand on the screen, the system mediates which address should be displayed, enabling indirect selection and viewing of multiple addresses without touching the screen or requiring additional display space.
2Ease of operation
If touch operation is used, then the interface is simple and direct, but it cannot prevent unintended scrolling and lacks precision
Solution Approach 1:
The patent replaces the mechanical touch contact system with a non-contact hand position detection system. Instead of requiring physical touch to select or scroll through addresses, the system detects the hand's position in proximity to the screen and switches addresses accordingly, eliminating unintended scrolling caused by accidental touches while maintaining ease of use.
3Loss of information
If multiple addresses are displayed, then the user can check all addresses, but the screen layout flexibility is reduced
Solution Approach 1:
The patent uses dynamic address switching based on hand position to provide all addresses sequentially rather than simultaneously. This maintains screen layout flexibility because only one address is displayed at a time in its optimal position, while all addresses remain accessible through the hover operation, avoiding the need for fixed multi-address layouts.

AI summary
An image forming apparatus includes a processor configured to switch one or more addresses to be displayed on a screen displaying the one or more addresses among plural addresses used for a transmission function for transmitting information according to a change in coordinates of a moving object without touching the screen.
